Random shutdowns with every rom - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi all,
I have an N910G in Australia. I have tried many different roms and different OS versions but always have the same problem of random shutdowns on low cell signal.
I'm currently running the Andycar rom because it's just a customised stock MM room and even uses the original CSC.
My phone has never been better but the random shutdowns are happening even on this room.
It can't be an EMMC issue because the phone is perfectly reliable on a stock factory rom.
My wife also has an N910G. I have the exact same issue on both device.
I just installed wakelock to see if it helps but it's too soon to know yet.
What am i missing?
Thanks in advance for any comments

Battery. There is a topic about it out there somewhere.

Only with non standard roms? Multiple phones and batteries, all working properly with stock roms, all will work for days with a reliable cell signal. All will reboot or turn off with a low or changing cell signal.
I'm not ruling battery out but it doesn't sound right to me.
My gut feeling is that it's CSC or BL related but I've tried original stock versions with the custom ROMs - same problems.
The last rom I tried was a customised debloated stock rom - same problem.
I'm lost ...

Hi all,
I have stared from scratch with another fresh install of Andycar customised stock MM 6.0.1 rom. I can use it around the house perfectly for days on end. Battery life and performance is awesome but when I go to work the phone will randomly shutdown every 10 minutes or so.
It's definitely not battery.
It's not EMC.
It's not the sim.
I've flashed modem.bin and NON-HLOS.bin from the stock rom (that works 100% reliably) but still I have the same problem that I've had with every single rom I've ever run apart from the stock Samsung rom.
Any time I go somewhere where signal is low the phone will soon shutdown instantly.
Is there anyone else in Australia running an SM-N910G on Telstra with a non standard rom?

Hi, I am not in australia, but can say this.... for what its worth, I have an n910v galaxy note 4 on a custom rom myself. I have set up 3 others exactly like mine. I have not used the rom you mentioned but am using the modestrom instead. none of the phones I set up have ever had random shutdowns. It may be a random problem with the rom itself. I know it isn't really helpful, but wanted to state it anyway.

Hey tattmann,
It doesn't specifically help me but I do appreciate the reply :good:
It's strange that i can produce the same problem on multiple (3) devices with so many different roms. I can't believe that no one else has had the same problems.
In every case I can restore a stock rom and the device will perform reliably - despite having horrible battery life, masses of bloatware and crappy performance...
Thanks again for the reply

With custom roms my phone is shutting down completely when i either open gallery or do two or multiple things at once. Weird thing is once its shut down i cant power it on immediately. I have to connect to charger or remove battery. Then its turning on when i press the button. Sometimes it happens irritatingly fast.

Question about battery

Just received a new T-mobile Wing today and I am underwhelmed by the stock rom. I am considering reflashing the rom but I have a question concerning the battery. My previous phone was T-mobile Dash which I also reflashed the rom on. However because of the reflash, something with the charging program got messed up which resulted in the phone shutting off suddenly when listening to music, using the wifi, or even making a simple phone call. A couple people on the Dash side of this forum experienced the same problems. So my question is, has anyone experienced a similar problem when reflashing their Wing/Herald to any of the custom roms available?
nope. we've never experienced that.
sometimes the devices turn off unexpectedly, but its rare and seems to be device specific
Yeah Never happened with us...Maybe you and the others got a "bad batch" of dashes haha...But the Wings alot better than the dash...Ive had both!! Welcome to the Herald Side of the Forum!!

Two Major Problems w/ TW Roms

Hello,
I've been flashing for a long time and currently I'm running Bionix 1.2. I've got 2 major problems and I have a workaround for each; however I thought the community might know better than me.
The first one is about the signal bars and dropped calls. I live in an area (Maine) where you never experience a dropped call since there aren't many people living. At least with my old MyTouch and stock Vibrant, I never had one. So almost once a day I drop call and see the all the signals gone. Sometimes, I see signals but there is no data or GSM connection since I cannot login to GTalk and other services (FB, twitter, etc.). I read in the development section that turning flight mode on/off can help. Well for me, it sometimes helps, sometimes doesn't. I find myself rebooting to solve the problem at least. I am a little concerned since I might need my cell in case of an emergency and I definitely would not want to wait for a reboot to call 911.
The second one is about the GPS. If I open navigation and ask for turn-by-turn directions, almost every time, it gets stuck searching for GPS. The workaround for me is to launch Maps, wait a few minutes to locate my location; then ask for directions. Although, this might not work from time to time. Again, in the middle of nowhere, you are driving and need a quick and dirty turn-by-turn directions and your smart Vibrant makes you go thru a lot of hassle to accomplish your task.
Any advice from our community?
Thank you!
Flash to stock, call t mobile and tell them your gps is non functional even after the froyo update, and get an exchange. My gps works INSTANTLY. Cold. I type my destination in Navigation and when I press enter my navigation is already talking. No maps, no 10 minutes, no downloads, we all know these are often placebos and we are still waiting and waiting for a signal which can still go off road randomly, etc. none of that with a new phone.
I did not try the physical gps fix in the forums but that could work too. Your gps still not be fixed by software, its a hardware problem. It seems phones manufactured after October (?) do not have the gps issue. Worth the hassle for me, at no cost if you do it for the gps issues and there is no physical damage to your phone. Just make sure you flash back to stock before you call because they will ask you to go through your system information on the line. Back up EVERYTHING and put it on a computer, get your exchange and flash back to your favorite rom and enjoy your now fully functional Vibrant that works in every way you bought it to work. And make sure you not only factory reset before you send the old one in, but also delete anything incriminating on your internal sd because a factory reset won't do it.

Don't blame the rom...Your hardware sucks.
Been running TW roms since the Bionix 1.0 days and NEVER had any issues.
Those problems are not inherent to TW roms, it's a problem with the phone.
@TheSneakerWhore, @deadpass:
OK - it might the hardware, but how do you explain no dropping calls on stock 2.1? I've used on stock for at least couple months and never had to reboot my phone because it did not have signals (or had signals but no connection).
I also flash Axura roms and never have a similar issue but they are too customized for me.
PS: I am not trying to blame the TW roms specifically nor am I defending another rom. Actually, if you open the latest Development thread, you will see my post thanking those guys because of an excellent job they've done. I am just not happy with the data and GPS - which I never had an issue before starting flashing TW and thinking others might be experiencing the same.
Strangely my GPS and cell signals seem stronger on TW ROMs than most others... It might be just slightly different hardware (not all units are created 100% equal after all) reacting differently to the software?
Have you perhaps tried Trigger v1.5? I thought the theming was very tasteful, you may like it, and it seemed pretty solid on GPS and signals.
Thanks, @Oxirane. I will give it a try.
I would try out different modems. For instance jl5 and kb1 great with gps in my case. jfd, ji6, ka5-7 all were teh suck when it came to gps. It all depends on your phone and location too. So flash away and find whats right for you.

I lol'd @ this "I live in an area (Maine) where you never experience a dropped call since there aren't many people living."
I'm with the OP on the drop call and inconsistent data issue. By all means, I have flashed almost every ROM out there. Every single ROM on here is awesome and all respects to the devs. I'm currently on Bionix 1.2 now for the third time and what I have and still noticed is the inconsistent data drop 2-3 times a day. No biggie since I managed to turn airplane off and back on and everything's back to normal. At first I thought it was KB1 that's causing this so I decided to try out different modems/kernals. After playing around a bit, I decided to stay with KA6 for a few days and noticed data improvement but still inconsistent (loss data connection). I also flashed the ROMs (Axura and Einherjar) and I don't have the data loss. I also flashed all the way back to Nero 5 just to check it out. I do not have any data problems with Nero 5. Anyways, I don't really mind every now and then switching air plane mode off/on. However, the issue as mentioned by OP does exist on some phones.
I'm running Bionix V 1.2, and the last 4 ROM's before this were all also TW ROMs.
I have not experienced a single one of your issues. My phone is fast, smooth, and have excellent signal and data everywhere around my area.
I doubt it is the ROM, but I'm no expert and cant say that for a definite.
But if myself along as many others , including a few buddies of mine, don't see those issues it just seems unlikely to be the ROM.
But who knows....
Well im guessing its the change of modems that's causing your issues... im sure it has nothing to do with the rom espeically since you never had issues supposedly when using Axura (since axura is based on bionix). Almost all the roms on here are based on TW roms, just change modems, theme, add a few random options, from what i've seen in the code. Like other suggested tryin flashing different modems and find the one that works best for your area. I've been running Bionix V 1.2 since day one and have not experienced any of the issues you have describbed...

I know your not trying to act up or anything, but thats kind of just mean.
I mean these devs are helping us by giving us more options.
Most of them aren't based on TW.
some are, most aren't.
but your saying "almost all the rom on here are based on TW Roms, just change modems, theme, add a few random options"
I'd like to see YOU edit the modem and theme and add a few random options and make a ROM. go ahead.
I can say that TW is also just editing a few codes and theming on a ROM that Samsung made, and that they aren't developers.
TW set a standard, a precedent, and people will follow it, but they aren't copying it.
not complaining at all to any ROMs. just throwing out my input to let the OP knows that he's not alone in this world. To me, if there's a way around the problem, the problem is minor. Besides, I flashed and used different ROMs like changing diapers. LOL. I like to keep my Vibrant looked different every 2-3 wks. Pretty soon, we'll see a flow of new ROMs and I be all over every single one of them like "flies on sh!t". Dang, haven't used that expression in a long time. LOL

there is not "editing of modems" its changing modems... and theming is nothing more then changing pngs and .9s and edit xmls... its not very difficult... time consuming but not difficult. as far as what TW does to their roms in decompiling smalis and editing the Java, i've personally only seen a handful tru developers here actually doing it to what samsung has leaked. MOST of these so called roms have taken the edits that TW has done and just dropped their own changes on top of them. This has been proven time and time again! but regardless you are entitled to youre own opinions.
My point is that Axura IS based on TW's edit so if the issues persist in TW rom but not in Axura, one of the causes would most likely be due to the modem cuz im 99% sure that several Axura roms use different modems.... that is all i was trying to say.
One thing I have not seen in any of the posts that are having the issue is what modem you are using.
I will say it now, KB1 modem sucks monkey balls. I haven't had any dropped calls on it, but have stale connections all the time. What I mean by that is, my phone is sending data packets, but isn't receiving any for a good 30 seconds.
So, try a different modem. KA5 seems to be the best modem for signal and battery life.

THX Krylon360. To be perfectly honest, I tried different ROMs and modems and noticed some significant improvements. I totally agree that KA5 and KA6 are better for me in terms of signal hence KA6 is what I stick with as mentioned in my previous response.
surprisingly, these problems can come up from odd combos of apps or some configuration that is unique........ Lucky you
I had some phone disconnects on my phone when it was on a TW and Eugene kernel, but it was a custom mms I installed that caused the issue..... so you might look at what you got on your phone as well. Remember, some of the app developers did not or do not update their apps and this may cause an issue especially running a 2.2 platform (especially a ported 2.2 platform) if they are older apps. Food for thought
I was having the same issues with 1.2. dropped calls, no data, constantly switching from edge to 3g, etc. had no issues with nero. As everyone said, try a different modem. Worked for me.

Thanks everyone! krylon360, I should have mentioned the modem I've been using: KA5. So, it's weird how you and some others find KA5 and KA6 to work best and I had all these problems with it. Maybe it really is a unique combination of apps, configuration etc.
Last night I flashed KB1 and will give it a try for a few days. I tried GPS on my way to home; opened Navigation and entered directions, and I got instant lock. I see that as an improvement. Will follow closely. Thanks again!

There's nothing wrong with the roms i been flashing since i got my vibrant once flashing do you wait the initial 10 mins and then reboot before you start using your phone? if not you may want to try that. TW roms are pretty much flawless.

[Q] Please help :( i9505 Constant random reboot issues..

Hey guys..
I've owned all the Samsung Galaxy phones from the S+ right up to the S4 and I've flashed firmwares over all of them with generally no problems at all.
But lately I have a constant issue that has been plaguing my Galaxy S 4 (i9505) phone since I flashed the 4.3 i9505G (GE Edition) ROM over my phone.. (have since moved to OMEGA v12)
The phone just randomly reboots whenever it seems to feel like it.
It could be whilst taking a picture, it could be whilst using google maps, it could be whilst installing an app from the app store or just scrolling across the screen. It's basically rebooted through anything and everything and I've tried pinning it down to something but every time I think that I've got it sorted out. It crashes again whilst doing something else.
1 thing however has got me stumped. The phone has NEVER crashed whilst plugged in. If I keep the phone plugged in, it's never ever just rebooted on its own for me. Which got me thinking that it could be a faulty battery or some sort of voltage issue.
Coming from the 4.3 GE Edition ROM there are other people experiencing random reboots. But now I've just flashed over OMEGA v12 and right after flashing (I did a full wipe of course first) the phone rebooted whilst typing in my Wifi access key. After the reboot I was able to set my phone up and I did a reboot myself, then I went to the app store to add an account and the phone crashed AGAIN.
I'm totally over this issue with my phone. I paid a small fortune for it and I cannot rely on it at all. So I absolutely need it to work. I've had issues on 4.3 GE getting Mobile Data to work. I've had issues with it crashing and I'm just done with all of this.
Do you think that my phone is already broken? (It's barely 3 months old) Do I need to get it replaced under warranty? Can I even get it replaced under warranty, is there a way to even get my warranty back or reset the flash counter etc?
I'm just so confused guys I thought maybe it was my battery, and that my battery was faulty because I had battery percentages dropping and jumping around like mad. For example 15% battery left would actually have the phone turn off... and reboot at 0%. Then the light wouldn't go green for 'Fully charged' and the phone would sit on 99% or 100% but still not say 'charged'. In addition I could swear I had lost more than 10% of my charge in the blink of an eye etc.
I just bought 2 new batteries but they will take a week to get here.. and if the phone is still rebooting (and it isn't a voltage/cut out issue with the battery) then should I assume it's a hardware issue and that the phone needs replacing? Or could it just be a bad flash or something? The phone has at least a 2 year warranty. I don't want to replace it after just 3 months when I haven't even so much as dropped it once.
My recovery is PhilZ 5 Touch 6.0.4.0
I always check MD5 sums before flashing and do a full wipe:
- Wipe Data/Factory Reset
- Clean to Install a New ROM
- Yes
- Then Flash the new .zip file etc.
What on earth could be wrong with my phone?
I'll happily provide any more information, as I honestly cannot handle this happening and I have no idea what my problem is...
Thanks incredibly much for any help at all, what-so-ever.

I can only give you advice on some of the smaller issues that you mentioned. I haven't had a problem with reboots at all (i've flashed all manners of ROMs too, including the GE), so I'm guessing it is hardware related. You should get it replaced (if it still is messing up with the new batteries).
As for warranty, yes you can claim it back on warranty. To be doubly safe, restore it to stock: http://forum.xda-developers.com/showthread.php?t=2265477
Use Triangle Away: http://forum.xda-developers.com/showthread.php?t=1494114
Also FYI, rooting does not void warranty: http://matija.suklje.name/rooting-and-flashing-your-device-does-not-void-the-warranty-in-eu (assuming you are in the EU, not sure about other countries) (gosh i've posted this a lot today).
Thanks a lot buddy I am in the EU definitely and the phone is purchased from the EU. I am actually about to flash it right back to stock now to see if it stops the rebooting issue. I will just have to live without custom roms for awhile and such. If it still keeps crashing I will wait for the new batteries. If it still keeps crashing again after I get those. I guess all that is left to do is render myself without a phone for a week or two and have it repaired...
I wouldn't worry mate it sounds to me like a definite battery issue

Hi leijonasisu,
I've stumbled across your post after having experienced more or less the same issues as you. After trying many custom ROMs in the last few weeks, the phone has barely been useable for more than a few minutes until it randomly reboots. At which time, I must start over with the whole flashing process. My question is, did getting a new battery resolve your issue? Or did you just trade the device back in?
many thanks

Looks like it's better to restore to Samsung stock firmware first then start again from there,
But this will upgrade the the Knox bootloader also.
Stock firmware can be downloaded here, www.sammobile.com/firmwares
I fixed this ages ago. It was a battery issue, I'd bit my bottom dollar that it would be a battery issue for anyone else too, I've read a lot of stuff online about people who have gotten bad batteries with theirs. Swapped to 2 third-party and apparently larger batteries and never had an issue and never looked back.
Sorry for not replying back much sooner but I forgot about the thread.
Try another battery and if within a day or two you get no reboots then toss the bad battery and enjoy your phone! The thing is the battery (due to voltage issues) can make it look like it's the OSes fault when in actual fact it's just a faulty battery and voltage issues.
same problem here.. s4 randomly reboot..
I got the same problem.
The phone reboots every few minutes on me when i want to take it out of standby.
Sometimes it works for a few hours and sometimes it just reboots itself every few minutes or it reboots when i want to do something.
So ur all saying that a new battery could solve my problems ??

Hi, the OLD problem WAS caused by the faulty batteries batch (easy to recognize - the battery serial no was beginning with BD code).
Now, more frequently it is resulting from KNOX related issues.

But i would like to have a custom rom and root again .
So how would i go from here to there without having random crashes / reboots on custom rom ?

Only one option then: read the ROM-specific threads, loo for feedback posts. If ROM would cause random reboots, you can be certain that it will be written there.
Same issue with gt i9505, random reboot, earlier i had gt i9500 that was flawless with all rom n root n with everything, but i bought gt i9505 and its random reboot like in every 30 to 20 mints, im totally pissed n disappointed ? plzz help....

For me kitkat UGNG8 with random soft rebooting, tried everything with that firmware I could, reset to default and it was still randomly rebooting when ever it liked. Usually after swiping the screen out of wake lock most of the time. I even re-odin GNG8 3 times.
Cured by Odin with this one, below, which I thought I couldn't, because of the backward compatibility of the dates, but it went in ok. No reboots for weeks. Cured my i9505 S4

Interesting will have to give this a go, also the battery option.
For months I was running on Lollipop custom ROM, the developer did an upgrade and then the SIM card removed error started. I went back to the old version was keep getting the SIM Card removed error. A few days ago went back to Original ROM for NZ 4.4.2 and I still get the SIM Card error and now the phone just reboots randomly.

[Q] Phone reception/broadcast on CM and ASOP roms

I have tried many times now to use CM or ASOP roms and their like and I find that I consistently have the same problem: no phone calls in (I would boot the rom and then call my cell from my house), can't hang up after a phone call and lousy GPS.
I don't have these problems when using a stock (Touch Wiz) based ROM.
Why is this?
Clearly it's a software issue, what could possibly be missing in the various roms that would make this happen?

Has anyone experienced this problem and has suggestions as to how to fix it?
Thanks
I flash a LOT of roms. Sometimes two or three a day. (I am going to meetings but I will always be a flashaholic.) I am almost constantly on AOSP because I do not like how clunky TW feels and there are about three or four things an AOSP rom does easily that you cannot do easily or at all on TW. I have had all of the problems you mentioned at one time or another but never all at once. When I first bought my SG4 and started flashing roms the GPS was a big issue but that problem is pretty much nonexistent now. The same with the inability to make a call. I have not seen that in awhile. I recently flashed a rom that I thought was running perfectly until I made a phone call and could not get the phone to hang up. I had to reboot to get the phone to disconnect. That was the first and only rom I have had that problem with. I think I reinstalled it a few days later after it had been updated and it worked fine.
Other things I have noticed is that Google's voice recongition does not work as well on AOSP roms and there can sometimes be a problem with MMS.
I say all of this to say that first, these roms are in development. They are not perfect. They sometimes have problems. If a rom has a glitch you cannot live with, go to a different rom.
Next, you have to follow the installation instructions to the letter. If it says to stand on one foot while installing the rom do it. I have seen some roms that have really weird install instruction but if you do not do it, the rom is not going to work. Acheron's Super S4 has you use specific recoveries and reboot into recovery. That is a little odd.
Next, if you feel you are constantly having these problems with all AOSP roms, which is odd, try flashing a stable version. CM has milestones. I know Liquid Smooth has an official 3.1 that is supposed to be very stable. See if you have these problems are more stable versions and instead of nightlys.
Next, I have seen people on the exact same model phone and carrier have greatly different experience with a rom. Individual phones seems to have their own quirks you have to learn. I believe most of this type of issue though is user error and you just don't realize you are doing something wrong.
Finally, the one thing I know nothing about is unlocking your phone for the international version. I wonder if that has anything to do with your problems.
Good luck and don't give up!

leeco pro 3 x727 shuts down after few minutes

This happens only when I install any custom rom...the phone works fine with x720 5.8.018s version...anything apart from that device will shut down every 2-3 minutes ...very strange behaviour ...any one has any idea ?
any custom rom , android 6 or 7 , AOSP or stock based, it will boot fine and after initial setup , it will work for 3-4 minutes and then suddenly device shuts down. .. when i boot it up again , same thing happens, in one minute shuts down.
if i flash 5.8.018s stock rom , everything works fine....and it doesnt shut down...
After device bugs, my phone finally was restored into x720 stock ROM (i have x720). On boot it worked below 1 minute and reboots. I had to do clean data. Also booting x720 ROM into x727 is not too good idea. Maybe you should try to do more wipes?

I did all the wipes i could , cleaned all kinds of data... it was US version 5.8.018s originally and i tried to flash Omni ROm first , and other ROMS , all had same issues, so i thought going back to the stock US rom , but since US version of 018s is not available anywhere, i went to chinese version , and it works perfectly , no reboot/shutdown...... I have used number of phones and installed 100s of ROMS , i have never faced soemthing like this...i hve even used leeco pro 3 before, with all custom roms and no problems.

Ok update...i downloaded x720 021S and 023S and updated using in build update option..(local update) , and it worked, 23S is working without any shut down...so i guess, it is problem only with roms flashed thru TWRP

Usefull information, thank you very much.
Nearly the same problem here: My X720 is only rebooting sometimes, but more often switching off directly (vibrates one time and switches off). While the phone is in that status, the battery is discharging. I can only reboot the phone by holding the power button for about 10sec or to TWRP. Two times I was rebooting the phone and some (not all) settings were restored to default - reflashed the rom... Another time rebooting the phone it hangs in the booting display, did not get it booted completely again - reflashed the rom.... Very strange behaviour and don't know why this happens.
But for about the last month, the phone is only switching off and I can reboot and use it for an unspecific time.
That all happens with several ROMs - currently I'm on ResurrectionRemix 5.8.5. This is the most stable custom rom I have tested, but anyways the phone switches off in irregular periods. Sometimes the phone is about a day alive, sometimes only a few hours, sometimes below an hour. When I'm playing HQ games I think the phones switches off much faster, but not sure.
I'm also not sure - I do not have used the stock rom really long after I get this phone (was CN 5.8.018s I think) - but my feeling is, that the phone was definetely more stable with the stock rom.
Now after finding this thread, I will give the stock rom another try. Would you be so kind as to describe the process of going to the stock 023S a bit more in detail? First flashing the 5.9.021S for the x720 ROM throught TWRP and after that using the build in update option (rename file to update.zip into root folder)?
Thanks!

You do not flash a 21s update twrp that may brick you.
You have to go stock and flash with stock recovery.
Their threads already on this.

Does anyone completely solved the shutting down issue on x720? I remember the same issue with the stock rom when i was getting the phone (5.8.018). but this rom could have been a shop rom, cant remember.
For me it seems that the issue happens more often whenever the phone uses more performance. Playing HQ games let the phone shut down after about 1-3min. doing nothing on the phone, it remains for about a day. Weird behaviour... will try to flash the stock recovery via fastboot and then a stock rom (no shop rom). hopefully it will improve the behaviour or even better solving the issue.
Sounds like a hardware issue. As for me, I have a couple of screen issues--I usually have my LeEco Pro3 Elite connected to a charger, and I sometimes don't use it for long stretches of time (say, 8 hours) because I have another phone as well. Once in a while, during those times the screen refuses to turn on. Sometimes the fingerprint scanner wakes it up, other times I have to straight up reboot the phone using the power button (I have to keep it pressed for two whole minutes for it to wake up the phone). Pretty annoying, dunno why it's happening. Could be a loose screen cable.
Now, if your phone is shutting down every few minutes no matter what, it could be a battery issue. I say this because I had a similar issue with an old iPod Color from 2005. The iPod would shut off every few minutes even when plugged into a charger. I changed the battery and it stopped shutting down.
Hopefully it's not a motherboard issue because replacing a phone's motherboard is never easy.

I don't think gameplay should affect the phone negatively at all. Especially a phone with a Snapdragon 821, a 14nm processor with efficient cores, for crying out loud. I play Fate Grand Order, a pretty intense 2D online game with 1080p graphics for 5 hours straight on my LeEco Pro3 Elite (Snapdragon 820) without it heating up at all.
Again, seems like a hardware issue because no phone with a Snapdragon 821 or 820 should be doing that. Especially while gaming.

Thanks for the information.
Could be possible... If I'm shaking the phone like a cocktail-mixer, it feels something loose inside it and this could be the battery of course which could be not fixed correctly. But I am sure, that this issue has also something to do what is happening on the phone currently. Sometimes I am going to bed and the phone does not move for 8hrs, it simply lays on the table. In the morning, it is shutted down. Need to hold the power button for about 10sec to restart the phone (usually hold 2sec to power on). Sometimes (not really often) it warm-starts automatically.
I think this could be also a memory issue or internal storage. Yesterday I was playing a game (Bowling by Jason Belmonte) and after 3min, the phone hung up, display remains on, no reaction on pressing the hardware buttons, waiting 5min... nothing happens. So I pressed the power button 10sec, phone seems to reboot normally, but it take a bit more time in my oppinion. Now after entering the pin, some phone configurations were resetted to default, but not all. Playing this came, it sometimes happened, that the phone switches off (with one vibration). Rebooting with a 10sec press and it runs again normally. This time phone hung up and some configurations were resetted to default. WTF?
Today I have played Hmmsim 2. Phone hung up again, pressing the power button 10sec, phone begins to reboot, but rebooting never finished (waiting for about 1-2hrs). Long Press power button (10sec) to try to reboot again - same behaviour, never ending ROM loading screen. Wiped to factory via TWRP and the phone reboots again, but all configurations lost, like freshly installed rom. OK, whatever, using the google backup for apps and so on... when installing the apps in the background, the phone reboots about 3-4 times, app installations not finished. Cancelled and shutting the phone down to TWRP, where I am now...
What I will try to say is, that whenever the storage or memory is used to much or something like that, the phone begins with that behaviour.
And now I am thining about what to try next. I think I will try to flash the stock recovery via TOOL ALL IN ONE then flashing a stock rom like 5.9.023S.
I am still not sure of a hardware issue...

The easiest way to tell is if the issues were occurring before you flashed TWRP. Were they? This is why you always wait a couple of months before modding your device. Otherwise you'll be stuck in a loop of doubts. By this I mean you'll be convinced that the issue has to do with your custom ROM or kernel rather than your device's hardware, but you have no way of knowing for sure because you never used the phone enough on stock firmware.
I was like you... my unmodified Zenfone 3 had a screen flicker issue and a headphone jack issue that I was convinced was a Nougat problem. I upgraded from Marshmallow to Nougat immediately after getting the phone. After a lot of research and posting threads on the Zenfone forums, I realized I had a hardware issue on my hands. The screen had to be replaced for the flickering to stop, and the headphone jack had been gimped to 0.3v by ASUS for some reason. I quickly sold the phone and got my LeEco.
Here's a thread I made on XDA about my screen flickering issue. It's a hardware issue: https://forum.xda-developers.com/zenfone-3/help/ze552kl-screen-flickering-lowest-t3660643
I've learned some important things from that experience: it's easy for your brain to trick you into thinking you've got an easy-to-solve software issue on your hands, when in reality you've got a hardware issue. You need to start making arrangements for a replacement device and get video evidence of your problems to show to the seller ASAP. Because that behaviour isn't normal. Now I hope you do have a software issue on your hands that the stock firmware will solve, but who knows. Be prepared for anything.

Thank you very much!
I am sure that the phone was doing the same on stock rom, but maybe fewer times. I have flashed a stock based rom now (Turbos mini 5.9.023s) and the issue still exists, but now the phone reboots normally more often than going into edl mode (emergency mode). I have found an old thread here on XDA and the issues described there sounds nearly the same. Finally the user in this thread also had hardware issue.
I believe also in a hardware issue, but I am still not sure. If I am looking to other threads regarding similar problems, there is always some regularity in the behaviour or the reported issues. In my case these rebootings (usual reboot or reboot to EDL mode) are definetely very unregular. On the TURBO Rom, these reboots happen definetely more often when the display is off and the phone sleeps. On the TURBO Rom, playing games seems to be helping lasting the phone a bit longer, the completely differnce to ResurrectionRemix Rom, where the phone was lasting longer when doing preferabely nothing. The issues are so inconsistant and this is making it hard to believe, that this is a hardware issue. Why the hell is the phone behaving different on every ROM - if it's a hardware issue, the occurred problems should have some regularity.
As I didn't have an OTA update option on the stock rom, I'd found out that this could be a "shop rom" (5.8.018), which is not the best choice nor for the first month(s).
I'm from Germany and I do not really want to return the phone to china or east asia for repairing (bought at banggood). This could take a very very long time. Changing to a new one could be also difficult because there are hardly any more devices out on the market and I need to return it for the change too.
But I am slowly at my wit's end and before these issues are making me more and more crazy, I will accept a problem with the hardware.

If your issues were occurring from the moment you got the phone, you know it's a hardware problem. Your seller sent you a defective phone and you should at least try fighting for a partial refund. If you paid through PayPal, open a dispute. If you paid with a credit card, ask for a chargeback. Now, the shop you bought it from might ban you for initiating a chargeback, but it's probably worth it. Or you could just cut your losses and move on. Maybe donate your phone to a dev who wants to try something crazy. :good:

Oh snap, it's a Banggood phone? I bought my x722 from Banggood. No glaring issues other than the screen one so far, but this does worry me for the future. How long have you had it?
This is the problem with Chinaphones. They're cheap, they've got good specs, but you can't guarantee quality. Especially with now close-to-defunct brands like LeEco. If you're still okay with Chinaphones, get a Xiaomi next. Probably the most reliable Chinaphone brand out there, next to Huawei. And try to buy from an official source. I heard The Solution Shop in Europe sells Xiaomi phones for cheap (?). And always remember to record your unboxings and document all issues from now on.

Admittedly I'm not sure at all if this issue was already present after starting the phone for the first time. One of the first things I have done during the initial setup wizard was using the integrated data transfer app by LeEco (scanning a QR code with the old Xperia Z, downloading app to transfer data to the x720). This app establishes a Wifi direct connection between both phones to transfer the data like apps and other stuff. This transfer process takes at least 6-7 hours and during that process I am sure that the phone was not rebooting a single time. Maybe a specific app or background process of an app causes this irregular rebootings. I have not testet this. I have installed the most common of my apps also using different custom ROMs later.
On the current ROM (Turbos mini 5.19.023s) I have now looked into the last_kmsg.log file severel times after the phone was hard-rebooting (not to emergency mode - the phone is switching down to emergence mode really rarely since I have flashed the stock based ROM) to debug for a kernel problem and the power off reason seems to be ""Triggered from PS_HOLD (PS_HOLD/MSM controlled shutdown)". In the log file I could also find some "kernel panic" entries. So I have a little gleam of hope that the issue is not a hardware problem. I have to test a bit more with the stock recovery/ROMto gain a better knowledge of the issue. I think I will post this into the ROM topic to ask a developer.

Now, the shop you bought it from might ban you for initiating a chargeback, but it's probably worth it. Or you could just cut your losses and move on. Maybe donate your phone to a dev who wants to try something crazy. :good:
Oh snap, it's a Banggood phone? I bought my x722 from Banggood. No glaring issues other than the screen one so far, but this does worry me for the future. How long have you had it?
This is the problem with Chinaphones. They're cheap, they've got good specs, but you can't guarantee quality. Especially with now close-to-defunct brands like LeEco. If you're still okay with Chinaphones, get a Xiaomi next. Probably the most reliable Chinaphone brand out there, next to Huawei. And try to buy from an official source. I heard The Solution Shop in Europe sells Xiaomi phones for cheap (?). And always remember to record your unboxings and document all issues from now on.

Finally - I got it working without any problems now!
Happily it seems to be not a hardware issue. I have flashed the Grossoshop ROM and Recovery via a provided .bat file. This .bat file has flashed the recovery first via fastboot, then the ROM via fastboot. This Grossoshop ROM was based on 5.8.018s I think. Then I have updated TWRP Recovery to the latest version via TWRP itself (flashed the new image). Then I have flashed Mauro's 2.2 (which is based on 5.9.023s) and it is running great! Super performance, no extrem battery drain, no reboots, all is working (except the chinese design downloads as I cannot create a Leeco account from Germany). But now I'm satisfied. :good::laugh:

Usefull information, thank you very much.
Nearly the same problem here: My X720 is only rebooting sometimes, but more often switching off directly (vibrates one time and switches off). While the phone is in that status, the battery is discharging. I can only reboot the phone by holding the power button for about 10sec or to TWRP. Two times I was rebooting the phone and some (not all) settings were restored to default - reflashed the rom... Another time rebooting the phone it hangs in the booting display, did not get it booted completely again - reflashed the rom.... Very strange behaviour and don't know why this happens.
But for about the last month, the phone is only switching off and I can reboot and use it for an unspecific time.
Thanks!

My x720 has done the same to me a couple of times now, Vibrates once and turns off and I have to hold the power button for a few seconds longer to turn it back on again which is odd.
The battery was charged over 50% % 70% at the times it happened and I wasn't even using the phone, It was just sat on the table in front of me.
I didn't have any problems at all until a few days ago when it first shut down.
I'm using Oreo - AICP 13.1 from here - https://forum.xda-developers.com/le-pro3/development/rom-aicp-13-0-pro3-aka-zl1-x727-x720-t3698058
The problem now is I don't know where to start troubleshooting When I get time I am planning on a clean wipe and fresh install of AICP again to see if that solves the problem
When using this ROM does your phone heat up a lot.

Did you manage to fix the problem somehow?
