constant system crashes

Hi there,
I bought my Galaxy Note one month ago and in the first weeks I never had any problems with it, but recently it crashes more and more often. A week ago, while I was still on stock rom (unrooted), it crashed 5 times at one day. I did nothing that could be a problem for it, I was sketching (Autodesk SketchbookMobile), browsing, playing games etc.
I thought it may be the best to try a custom Rom, so I rooted my Note and flashed RocketRom v20. But soon after that the same problem appeared, and besides that, I needed after every crash more than 10 trys to successfully start the phone, somestimes it stuck at the "Samsung Galaxy Note" logo, sometimes it even accomplished it to get to the PIN-input, but crashed at it.
Yesterday I flashed RocketRom v21, but nothing changed.
The only thread about crashes I found in this forum says it may be because of S-Memo, but I barely use it, and never had problems while using it.
Right now I'm holding my Note in my Hand and try to start it, it's attempt 30 or so. I really love the Galaxy Note, but this makes it hard to use for me.
I appreciate every attempt to help me.

seems like manufacturing defect. If you are able to enter download mode, then flash Stock ROM which is latest for your region. then go for a replacement.

A few minutes ago I wasn't even able to get to downloadmode or to charge the phone, but after I plugged it in and out a few times I somehow managed it to get to download mode. I flashed the stock Rom, but the phone again stucked at the "Galaxy Note"-Logo the first two attempts to start it, now, again, it shows no reaction.
It seems like I have no other choice then to send it back

Sounds like a hardware defect with the internal NAND that might be accounting for the random freeze/reboots. Bad RAM can also do this.
Bad/ Corrupted sectors can do that. Lawl.
Also, list all apps that you've installde from the market. There might be some conflicting processes that's causing the phone to hang.

And first to be sur take your sdcard out, and test sometime bad/defective sdcard can also have dramatic effect.

It's already on it's way to Amazon.
I tried starting it without the sd-card, but that didn't help.
I hope it doesn't take too long, because i can't handle the tiny screen of my Samsung Wave anymore.

You are not the only one with this problem. Mine also started crashing/turning off randomly after approx 1 month of buying. Again on stock rom unrooted and very few apps installed.
Starting to think that just maybe samsung have tried to push the boat out too far by releasing this device. Don't get me wrong I love it (when it works) but it just seems too buggy atm. And I don't think ICS will cure all these problems we are all having. I know every device has a small percentage of faulty products but it seems that the note has a high percentage of those.
Sorry to be so negative but when you spend 600 euros on a phone you expect it to work for more than a month.

[Solved] Samsung Galaxy Note 3 SM-N900 Random Restarting/Rebooting

[Solved]
Original Problem
Hi All,
Hope someone can help me, as the title states I have been getting random reboots with my Exynos Version note 3, SM-N900.
I am currently running 4.4.2.
Here are the problems I receive:
Constant bootloops. (Can only be solved by doing a battery pull)
Randomly cuts off (no shut down animation) (Doesn't always come back by pressing power button)
Around the camera area is warm when it cuts off or is bootlooping, but not so hot that it is burning, it has been hotter while gaming.
I have tried everything,
Clearing cache.
Factory Reset.
Safe Mode.
Reflashing Rom with Odin.
Didn't reinstall any of my apps.
Didn't disable any apps.
Please note that I was rooted when this first occurred. I unrooted and reflashed the rom and it has still been occuring.
Also note I got the firmware from www.sammobile.com, and the reboots never occur while the phone is charging.
Can somebody tell me if this is a hardware issue, or just plain software issue.
I have tried just about everything and I can't seem to find a Jelly Bean rom to test the issue.
Should have Bought the Qualcomm Version
Any feedback will be appreciated.
Thanks.
Solution!
Finally found a solution!!!
After I changed my sim, it didnt random reset for a while till two days after and the restarting and overheating returned.
So I dug up through a lot of xda forums on random restarting.
Wish I could remember which one so i can quote.
But he basically said that knox was the issue on his.
So again proceeded to re-root and uninstall anything with the name knox.
I used nobloat free and link2sd just to be safe.
Since then no overheating no restarting almost a month now.
Hope this Helps anyone with the same issue.

I may be wrong and hope I am... but this sounds to me like a hardware issue.:fingers-crossed:
If it was a software issue flashing Original rom and no custom apps plus safe-mode should solve it.
normally the side of the camera heats up when doing processor intensive things. The phone shouldn't do that when idle ans standby.
Did you drop the phone or something similar happened recently?

Really hoping its not hardware..
No the phone never fell very hard it fell on carpet once but it was already giving problems before it fell.

Have to agree with smartjais. Thermal protection will kick in and shut off the device if the processor gets too hot and won't turn back on until it cools down below the threshold.
It almost sounds like the cpu either isn't dissipating heat properly, or you have a faulty processor in general.
You say you were rooted when this started... did you happen to overclock or adjust cpu voltages on a custom kernel before? If so, is possible (unlikely, but possible) that you may have damaged the soc.
Either way, it sounds like hardware to me.

No did not overclock or install a kernel, it was stock just rooted.
The phone does not get ridiculously hot, as it has been hotter when gaming.

what version bootloader do you have?

hmm A friend had a similar problem with the GS4 and it turned out to be hardware.
Are you still under warranty ??
I know knox might be tripped when you rooted but since its Exyeos version you can try to reverse knox counter.

Hi Guys,
Thanks for the response i'm not sure what version bootloader i have.
I think I isolated the problem, the heat was mainly from the sim card port.
I changed my sim card and it was still overheating.
But I left the battery cover off, and played with the sim card while it was on (like put pressure on it and try moving it while it was still on) , and what do you know?
Bootloops and cut off everytime.
I was in my office at the time so i folded a 2 pieces of paper. 1 in between the battery and the sim and 1 where the sd card supposed to be.
TA DA! No overheating or bootlooping almost 10 hours now.
I don't know if the port was loose or whatever.
I'm monitoring it over the weekend and will report back.:fingers-crossed:
Thanks for the help guys.:highfive:

Ok that's cool :highfive: .. Didn't know that lose mem card or battery could do this. Hope the issue never comes back.. Do update us after you monitor .:good:

Some years ago i used to have an lg gw620 and it dropped down one day after that it started reboot itself with no reason ..... If it doesnt reboot when it charges i guess it means that your motherboard is cracked somewhere .......

Final Solution!

After I changed my sim, it didnt random reset for a while till two days after and the overheating returned.
So I dug up through probably hundreds of xda forums on random restarting.

Had the same issue on a Galaxy Tab Pro, disabling all Knox apps didn't do the trick as those apps kept running anyway. Uninstalling solved it!
FWIW, in my case, the reboots happened after turning screen off, whether manually or automatically. OS version was 4.4.2, latest firmware for the tab at the time. I used my app, 3C Toolbox to uninstall the app in case I needed to install them back. One (soft)-reboot to unload knox completely, no more random hot restart.
Thanks for your thread, my Tab is working as expected now. Just wanted to share my experience.

[Q] Samsung Tech got my phone worse

I think they got my phone worse, I'm planning on take it back to Samsung but first I want the opinion of you guys since I've learned so much in XDA and they are so much "pros" in here.
I would like to know if there is something I can do? Is there something I should say to them? and mostly ... Should I ask for a full refund for the new $330 main board that DID NOT fixed the problem or they did well?
The beginning :
- I bought a N900W8 in september 2013, since the very beginning it had a multitouch problem, when XY from a finger aligned with the XY from another finger, one of them would disappear, it wasn't such a problem for me since the odds to trigger the bug wasn't that much and I had warranty.
- Kitkat was out and I couldn't help myself and updated it to the mexican leak, since it was "Knox-trigger free" and "downgreadable" I was still planning to take it to warranty if the problem with the touchscreen persists.
- Everything was fine and it didn't had the problem anymore, kitkat was amazing, rooted it, installed X-Note, my phone was great. Months passed, I updated it with the canadian Kitkat NB7 and more months passed.
- So, it's september 2014, I was reading reddit on my phone and it started to lag bad, like unusable bad.
Diagnostic :
- Later I notice it's not lag, it's a delay with the touchscreen. If I used any voice assistant app It would work perfectly but if I touched anything on any spot, it would take like 30 sec to recognize or it would act like I was long pressing it or double tapping, same thing with the pen and the physical buttons (volume, home, power). I spend nearly 20min tapping everywhere on TWRP recovery mode and there was no delay, the physical buttons worked perfectly too. EDIT: every time I installed or re-installed a ROM every tap/physical worked perfectly when selecting (next, next, choose apps, etc). the delays started after booting the OS.
What I did :
- Clean up the phone, check RAM (max was 10% still had 15~45sec delay), Format, Hard Reset, Reinstalled Kernel, Reinstalled ROM, Downgrade ROM, tried another Kernel, another ROM, 3 more ROMs, 2 more Kernels, flashed everything stock, tried stock with custom kernel.. NOTHING. The only thing I couldn't do was to flash Jellybean back because I updated to NB7.
- Took it directly to Samsung (Knox was still 0x0 but there is NO 4.4 update in my country yet so warranty wouldn't cover it) the guy said it was too weird, I took care of my phone so much, he though I bought it 1 week ago not 1 year lol.
What SAMSUNG did :
- After a week they told me it was the main board / motherboard, charged almost $330 for a new one.
- Went to pick it up, the guy turn it on and handle it to me, I even couldn't choose the language because the delay was there. He immediately called someone on the phone, and told me he has to take a video when the problem occurs, but when he inserted the battery back my phone started to work perfectly, almost 45min later was still good so he told me to go back if something happens again. My Scover didn't work, they told me it's "normal" for the Scovers to broke (it did worked before taking it to repair).
- 3 days later I decided to install 4.4 again, but this time I was not going to update it so I could downgrade to 4.3, long story short, I flashed 15 times and downgrade it 16 times because everytime I was on Kitkat the incredibly annoying delay cames back and it fixes when I flash JB back.
New problems :
- The problem persists on kitkat dissapears on jellybean, I haven't tried the updated firmwares, just the leaked mexican one since I needed to downgrade android.
- Scover makes my phone flashes like I'm open it and closing it.
- Every re-boot the half botton of the screen and the volume/home buttons, back and menu, won't work, the power button shows a black screen with the options on the top. I have to pull the battery or shutdown- turn it on in order to solve the problem.
Thank you for reading !

Note 4 freezes and restarts issue! Ultimate thread

Hello everyone,
I've had my note 4 over two years now and out of nowhere problems started happening after second MM update, model SM-N910F was freezing and restarting and sometimes was not able to boot normally and got mmc read fail.
I'm reading a lot about this problem in other forums and here, so hope someone could help about this issue.
No Success:
I tried anything from removing sd card, removing sim card, changing the battery, resetting the device, cleaning the cache, flashing the room through odin, flashing the rom with pit file and doing a re partition (Didn't tried Nand erase).
Success:
The only way that I was able to fix the freeze issue was by installing app called Wake Lock and enabling PARTIAL_WAKE_LOCK.
But using Wake Lock has its disadvantages. First of all you need to run the app all times which its not practical and second it wipes your battery because it keeps device and processor awake.
Please join this thread anyone who has similar issues with the aim to fix or bring the phone to an usable state again.

I also purchased my GN4 about 2 years ago and just recently got this error. This is really fishy. Wouldn't be surprised if it was Samsung trying to screw over all the root users and get us to upgrade to newer models.

Did you tried Wake Lock if it works? Which model of GN4 do you have ?

Yes, I'm on the Canadian SM-N910W8 model of GN4.
I've been using the Wake Lock app for a few days now and it works perfectly, if you can get the phone to boot into homescreen that is.
For instance, when the phone shuts off due to low battery or an inevitable crash, sometimes getting the phone to boot up is a real pain in the ass because it doesn't boot up correctly most of the time.
However, one odd fix I've discovered is to put your phone and battery in the fridge for about 2-3 minutes and let it cool down completely. And then magically your phone will boot up properly to homescreen again. Activate Wake Lock and you're pretty much good until the next time your phone shuts off and can't boot. My phone will NEVER boot up to homescreen if it is even slightly hot in temperature. In order to boot, it needs to be cool.
I am highly confident that this is indeed a hardware issue, instead of a software issue. The mainboard fails to read memory properly which probably indicates that the mainboard needs to be replaced. I however cannot afford to do this so I hope that I can last atleast 2-3 years of my GN4 surviving through Wake Lock. :crying:

I really don't think it's an hardware issue but even if so, why this started to happen immediately after the update and why it only happens when the device goes to sleep or when we power on the device.
I also noticed the change on bootloader fonts and interface after the update. I'm suspecting that the problem is there.
Does any one has any thoughts about this?

It's a hardware issue. It's a bad nand issue in fact. You can find Reddit posts a mile long about it.
Anyways it will slowly get worse over time. Had to replace the main-board in my SM-N910W myself.

Is there any reason at all why it is happening I mean for the nand issue. I don't like the answer that is motherboard fault and we should replace it, which probably means replacing the phone. Is there anyone who can see deeper into the motherboard to find the issue. I also insist that this started to happen immediately after the second MM update.
I still have an IPhone 3G from 2008 and never changed anything on it. Isn't that ironic ?

It was a Bad batch of nand chip that started to go bad after a year or two. Note 4s started to drop like flies before April.
I think your in the 1st stage of Loss and Grief. 1st stage is denial.

If thats so than Samsung should repair our phones under warranty and not tell us we have to pay for the repair coz we installed custom roms.

I would be more interested in understanding how come so many Note 4 devices started acting up around same time mark...

This is definitely a hardware problem with the motherboard. Mine started giving the same symptoms 2 weeks after the 6.01 upgrade. Wakelock made it stable but after Samsung replaced the motherboard it is so much faster and no issues at all. I wonder if this is a faulty NAND issue whether the 6.01 upgrade and the way it manages memory could have triggered it. Certainly strange but it need Samsung to fix it.

I am also having same problem.
I was using custom rom and it was working fine without any lag or freeze suddenly one day my Note fall from bed to ground and since then it is not working properly i thought its the ROM so i reverted back to stock MM rom flashed via odin.
Reset everything erased everything but the problem remains same.
At present i am on stock with hardly any apps just FB and whatsapp.
But my device is so slow and keep lagging and sometimes it becomes very hot and restart itself.
I dont know what to do now. i m on 910 G snapdragon.

Sorry to hear that, as for now jut install wake lock and enable partial_wake_lock so you can use your device until it fails completely

Mmm. I was thinking to root my phone (4month old still under warranty ) i think i changed my mind after reading this ?. Thank you guy's for the warning
Sent from my SM-N910G using Tapatalk

Same issues, I downloaded the wake lock and so far so good.

I have the same issue also guys and it started a week after updating to Marshmallow.
Phone worked perfectly fine for 2 years prior to this. So I highly doubt its a hardware issue and more likely a software/firmware problem.
Phone seems to have issues whenever the screen is asleep (hence why the wake lock app seems to help with this problem although not a proper solution)
I'm hoping Samsumg can release a patch fix for this as I truly love my Note 4 and would like to keep it for some time yet.

have anybody tried going back to Lollipop?

I was thinking about that! but I saw on other threads people downgrading with no success.

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!

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.

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.

it was the same with the ROM that came from the factory.
I experienced 21s and 23s beta Tars, 23s original Chinese...

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.

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:

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.
