Does your SGS ever turn itself off randomly?

Since I have got it (2 weeks ago) i have picked up my phone make a call, and on about 7-8 occasions, have noticed that the phone is turned off, and I can't get it to turn on. The only solution is to take out the battery and put it back in. Has anyone else experienced this. I have updated to JH2 firmware, but it still happens. I even got a new battery for the phone (Bell employee let me swap with another phone that was going back to samsung for gps issues), but the problem still happens once in awhile (like every 2 days, sometimes more sometimes less). Anyone have any ideas? thanks

More likely that it just "freezes" and you can't get it to react, then the solution is to take out and back in the battery - Sounds like a defective unit to me.

i think your phone was unable to wake? i have that problem previously where i can still call through my phone (using another phone) but there's no vibration / notifications of sorts.
i then realized i've been playing with SetCPU of late, long story short, i uninstalled the application, rebooted and all is fine since then.
good luck!
if it still persists, i'd do a reflash, wipe every bit of data available + formatting my SD cards. lol.

So..are you saying that the phone is actually still 'on'...just the screen is not turning on?

yeee sort of. lol. but why it's unable to answer, yet able to receive calls. i have no idea. same goes for any kind of notification that wakes your screen (SMS, calls, alarm, etc.)

Next time it happens, i'll try calling the phone to see what happens...I dont wanna return it because I have a 'rare' phone that seems to have good gps and can enter recovery mode.

you should check bell to see if there working and have recovery mode i got my just recently the newer shipments are hopefully all working with recovery mode and good gps

Did you install any Lockscreen app or something similar? I´ve read about another guy who had similar problems with a not waking up device. And it was a lockscreen app that caused this.

Yeah, I agree with everyone. I had SetCPU on my device and it would shut off a bunch of times per day. After I unintalled it everything worked fine. Another trick you can try is when the phone "freezes" try to hold down the home key. You sould still get the task manager box.

My first SGS did this a lot. My second and third SGS have not done this. Conclusion: faulty.

Yep...
I'm with mine for more than three weeks now, and I've never managed to cause it to freeze/shut down. although yours considerable rare, You'd rather have a working device I presume...

No, i haven't installed any apps like that. Like i said, GPS works 'ok' on this phone and it enters recovery mode. Thats why I would hope its a software thing and can be fixed. I will go back to get an exchange today ONLY if they let me try it out 1st (recovery mode).

I've had this happen twice, both times I was charging the phone with the screen locked and the cable was accidentally violently jerked out, after that my phone wouldn't turn back on without a battery pull. It has not happened of it's own accord though.

Note 4 Randomly Turned Off Won't Turn On Anymore

Hi everyone, after trying everything I could to fix this phone I don't know what to do anymore so I'm here asking for other options.
So the story is, I was just using my phone as I usually would that day and it just randomly turned off and won't turn back on anymore.
(it randomly turned off before a couple of times but it would always turn back on)
- It won't go into recovery mode or any other of the 'modes' (I tried all the different combinations of pressing the keys).
- It's not a battery issue as I've tried my battery on my brother's phone (he has a Note 4 too) and it worked fine and I tried his battery on mine and it wouldn't work.
- I tried the 'drain' method (removing the battery and holding the power button for a minute or more).
- I tried using multiple cables to charge my phone nothing worked.
I didn't drop my phone, wet it, root it or anything and it was working fine the day it happened until it just powered off by itself. When I plug it in my laptop it would make
a sound indicating I've plugged something in but nothing happens. It was version 5.1.1 model SM-N910F.
TLDR; Is there a way to somehow recover the files in the internal phone memory?

This is happening to me as well, also started in February. I'm suspecting a hardware issue. Tried it ALL but rooting. In the past 30 minutes my phone has booted and rebooted itself till it died. If someone can confirm it is a hardware issue. Maybe it's time to unite and get it fixed for free. ~Tamarnouche

Recovering data from a brain dead phone may not be possible, as it probably need some internal component replacement which may erase the data(Mostly). Have u tried connecting it to pc? Better give it to service immediately. Good Luck.

My phone has done exactly the same thing, happened in February too, initially it did the random freeze then started to reboot itself, went back to stock software and full wipe but no improvement; now it will only boot if I leave the battery out for a prolonged period, otherwise it doesn't respond to the power button at all.
I occasionally see MMC Read Fail on boot but not all the time so presumably the internal memory has a bad contact or is failing.
Can it be replaced?

I have the same problem with my Note 3. Only if I keep the battery out for a long (over 24 hours) time I can see the boot logo. So if you find a solution to this kindly don't forget to tag me, will really appreciate it.

I was wondering..
I came across this Forum group since I was looking for boot problems with my SM-N910T3
I hope flashing pit will resolve this..
I recently started to have some low level issue and was hoping it was partition/boot related and not hardware.
Randomly phone boot directly into Download mode with error;
ddi: mmc_read failed
Often I have to pull battery and hold down /power / home for 10 sec to boot up again.
Thanks

Galaxy Note 4 constant freezing & restarting!

Hi there,
So my galaxy note 4 is having some serious problems for the last couple of days and it's really starting to bother me. I've tried doing everything I can find online so far but to no avail I've had no luck at all. Basically, my phone constantly keeps freezing and restarting. It will crash for quite a period of time then restart itself, crash and restart. It probably crashes and freezes about 80-90 times a day? More if I'm trying to use it of course (It also resets itself when not using it).
I've tried everything, bought a replacement (genuine) battery and not fixed it. Got to the point where I seen online about doing a factory reset so I backed everything up to my computer, started the factory reset and when I was going through the setup of logging into google and samsung account, it continues to crash and freeze all over again. (It crashed & restarted whilst retrieving my apps from google, thus I had to reinstall my apps again manually after I finally got it setup again).
To make matters worse, I cancelled the insurance cover last month and only a few days ago this started happening. I've not dropped the phone or damaged it in anyway, screen is completely perfect too. It just constantly crashes and restarts on it's own. Get a phone call and it crashes, using google maps, crash. It's beyond unusable now. I still have 4 months left of the contract before I'm due an upgrade and I really don't think it will last me that long.
Can someone PLEASE help? Suggestions would be so helpful!!!
Thank you!
P.S Phone isn't rooted, only using Nova Launcher prime.

Sounds like your battery is on its way out. Have you tried a new battery?

Earlier in the week I had an error I've not seen before. Phone restarted and went to black screen sort of looking at a recovery screen with android logo and in the centre of the screen was the message
"Kernal Panic" with some information on the top. This only has happened the one time and hasn't happened since. Took the battery out and restarted again...

How do I go about doing either of these....
Still happening and it's driving me insane, It won't last me until the end of my contract (January)

Its rebooting 80-90 times in ONE day? Good god! Have the phone turned off then. Unnecessary pressure is being put on the phone mate!
Factory Reset isn't going to solve it anyway, its for tiny problems. Your system is somehow messed up badly.
Do what the above member said. Flash a stock ROM via Odin. But before that you need to completely wipe the phone. To completely wipe you need a custom recovery like TWRP. So flash it now, root the phone, then reboot into TWRP and use the Advanced Wipe section to wipe everything (external SD not needed), then reboot the phone in Download mode, and flash the latest stock ROM via Odin.

You are now part of a large group of us having the same issues. Several things have been tried. One thought is that the motherboard is faulty. Replacing it would be expensive. Download the app "wake lock" and set it to partial_wake_lock. Don't ask me why it works, but it does. Apparently the phone goes nuts when the screen tries to go off, the partial lock keeps it from crashing. That makes the phone usable, hopefully a permanent solution will become available. ;( The only time it goes nutty again is if the battery runs down and when I restart, the app is not running. Going back to the back and setting it to partial has allowed me to play games, etc for extended periods of time and no problems. It shouldn't be that way, and I really suspect the marshmallow update and then security update screwed it up, it was fine before that.

Which version is your note 4? verizon? att? tmobile? sprint? etc united states variant? other country? This helps find out if others that are having the same problem are on the same setup as you and more importantly tells me if I'm likely to have a problem with mine getting ready to come. :laugh:

80-90 times in one day is probably being generous. I've not actually counted how many times it restarts but If I need to use my phone I can guarantee it will be restarting a couple of times. Driving using navigation *Crashes* Inbound phone call *Crashes* get text message *crashes* all followed by the phone restarting. Practically unusable.

I'm gonna give this a go and hopefully it'll help! Thanks for the advice. Funnily enough, for a couple of months the phone has been prevented from the screen going off. I get a text or a notification and the screen would stay on until I hit the power button to turn it back off. Get a text in the middle of the night and I'd wake up to a boiling hot phone the next day, almost too hot to even keep in the hands. This literally frustrated me beyond belief and had to get a new battery and all sorts of complications. Also you mention the android update which made me think, I NEVER had this issue before I installed the security update for 6.0.1 - I put my money on something really stupid that's sincerely knackered my phone for certain!

While upgrading a phone, especially for major upgrades like from LP to MM, OTA method should always be avoided. You MUST do a clean flash of the ROM, otherwise you are bound to have problems. 80% of time people complain because they didn't flash the ROM cleanly, so whatever you want to do now, do it, but if it doesn't solve it (very likely it won't), then kindly flash the ROM via Odin after a full wipe. And if even that doesn't solve it then its hardware.

Thanks for letting me know your version. Hopefully it wont affect mine since mine is US Verizon. But out of curiosity have you checked for even the slightest sticky button? I've had phones where a button started to get tacky and would cause it to keep the screen on or go on and off like what you're saying. May not even feel like a sticky button. Do they all click very responsive? or do any feel like they have a dull thud experience?

The volume rocker and power button feel really loose but this isn't really something new. Something I have noticed is when I take the cover off the back, the battery barely stays in itself. If holding screen upwards and battery cover off then It doesn't hold the battery which made me possibly think that perhaps the battery does not situate properly and doesn't deliver enough power (or too much) but this was just one of my theories into why the hell my phone is acting this way.
Edit:
Forgot to add I'm running the security patch 01/08/2016

Are you able to wedge a folded small piece of paper between the bottom edge of the battery and the phone to make the battery fit tighter? I mean it's not good to have a loose battery. But I can't see how that would cause the screen to stay on. If anything I would think it would cause the phone to shut off or reboot.

Let me know how it goes. There are other threads about same issue. Most of us have tried reflashing, wiping everything, custom roms, going back to stock, trying to downgrade, taking out the sim card, taking out the sd card, not having both in at same time, brand new battery, I think even putting the battery in the freezer momentarily, etc. etc. Nobody seems to have had any real luck with it, except those who were under warranty and got a new phone, or are capable and wiling to exchange some hardware. I just find it odd that it happened all of a sudden after updates and recently to many people.. Still, I keep coming here hoping someone will have great news. Mine started with marshmallow, but definitely got worse with the security update.

Aside from the previously proposed wake lock solution, members in the T-Mobile Note 4 threads have experienced limited success with a downgrade to LP from MM.
From my reading, these issues seem to be common across all Snapdragon models, not to say it Exynos is excluded (I don't frequent Exynos threads).

Well a new motherboard was the only thing that fixed it for me, replaced under the 2 year warranty but I had to wait a while for parts. What is interesting is that the phone is much faster, the battery life much better than when it was new. Also it now barely gets warm using google maps - before it got quite hot. It would be very interesting to find out what percentage of Note 4's have been going down with is problem - mine was a fairly early one - was Samsung rushing to beat Apple two years ago and a bad batch of parts used? I don't know -we need some answers on what is the problem to be sure.

Just a personal experience and thus advice, please don't keep flashing bunch of stuffs every other day. The more your eMMC gets used more chance of your phone getting messed up. This is how my Note 3 died, kept flashing this and that, and did the same on Note 4 too, but have now stopped. I don't know whether there's an endurance rating on these eMMCs used or not but this is what I think, I could be wrong, please quote me in that case.

Wow, that sounds promising. I'm sending mine for replacement, and although I'm not getting a new MB installed, hopefully the incoming unit will be similar in performance to yours.

Your reasoning sounds plausible, but my phone suffered similar issues and I only flashed my unit 2-3 times in the 14 months I had it.

Help! Bootlooping out of the blue for NO reason

So... For no explainable reason my phone has gone into a bootloop, simply from me attempting to restart the phone.
Details of anything I can think of that might be related are below. I need a genius to help me A) figure out WHY this happend, B) help me figure out if there is a way to (non-destructively) get out of this bootloop (i.e. NOT having to do a factory reset), and / or C) tell me if there is a way that I can perform a full system backup using ADB, Fastboot or Odin with a phone that can't get past recovery or bootloader without going into an endless bootloop. I'm not a lazy guy and normally take the time to research problems and figure them out on my own, however at present this is my only activated phone, it's almost 11pm, I have to be up and out the door at 6am tomorrow, I will be judging competitions all day and will not have any opportunity to do anything about this until late tomorrow... In the meantime, I need a functioning PH1!!
My PH1 is the Sprint variant and I have not rooted it nor have I unlocked the bootloader. The only thing I have "done" to the phone is to sideload the latest OTA, NMJ32F (the day it came out, over a week ago, and it's functioned perfectly since that update). My phone has been in use throughout the day today with no difficulties. I went into a building with very spotty service for several hours this evening. On the way home, I noticed that I was stuck in 3G service, despite being in an area I know has good 4G/LTE coverage. I also noticed an unidentified icon on the status bar, a rectangle, which was located (I believe) to the right of the battery icon. It looked like a rectangle, perhaps representing a screen, or a phone? IDK. The other item of note is that I did sign into the guest account on my phone so that my daughter could use the stopwatch for timing competetion events without tampering with anything. She didn't drop it or get it wet or anything along those lines... she used it to time events, returned it to me in perfect shape. I logged out of the guest account, back into my account, rebooted to try to get the phone back into 4G service, and boom, I'm stuck in a frigging bootloop for no apparent reason.... And I'm about to lose my mind over this.
I CAN get into download mode and into recovery mode by holding the appropriate button combinations when it loops, but from there whether I power off and power on again or whether I select reboot from recovery menu, it continues to loop...

Well folks, still strange, still unexplained, but I had to bite the bullet and factory reset, just can't afford to wait. I'm still open to any thoughts on what might have gone wrong though I suspect we'll never know. This phone has been a bit buggy from day 1, things like BT randomly shutting off, VoLTE wouldn't stay enabled, etc... Hopefully this is the last time this happens. Still love the phone though!

So I am running O beta rooted and last night this happened to me. I ended up going into fastboot and starting OS through there and I had no issue with the reboot bootloop. However, last night I went to bed with a phone @ 75-80% and woke up 6 hours later with a dead phone. Charged and rebooted this morn and everything seemed normal today. It was super wierd

Had to return mine for this very reason. Less than a week in service and went into boot loop. The reboot happened after it lost all battery power (corrupt filesystem?). Several factory resets did nothing to fix it. Removed the SIM. The phone was also fully charged. Did not try ADB as it was brand new and a return was the safest easiest option.

I am stuck with the same problem, and this is my second phone already. This one doesn't stay on long enough even for an attempt to factory reset. I will send it back again, but I have no hope. Time to cut my losses and move on. Going to Pixel. And I sooo wanted Essential to succeed!

If it's your second phone, have you looked at what applications you install?
The probability of getting two bad phones is pretty slim unless there is a major manufacturing flaw.
Not saying it can't happen, but it would be unusual.

Could it be due to Encrypted Data partition?
It once happened to me on a Huawei Mate 2 which I encrypted data and battery dead, then bootloop.
If that's due to corrupt encrypted partition, there seems only other recovery mode can help you get some files back.

Random boot loops on new Redmi Note 7 (Stock 10.3.5 MiUI non root)

Saturday night, I plug my 1 week old phone on the charger at 9%. I power off the phone and see the battery charging animation. I turned it back on as usual but this time my phone did something I've never seen before.
It started bootlooping!
I was like what the hell.
It loaded up to the lock screen and then rebooted. This happened over and over again for about an hour.
After googling, I found a thread about a Redni Note 5 pro having the same issue.
The solution was to hold power and Volume down until the phone rebooted to recovery.
After doing that, I was presented with the option to reboot to system, wipe phone (which I definitely didn't want) and connect to My Assistant.
I chose the first option and sure enough....my phone was stuck in a boot loop once again.
This is my first Xiaomi phone. It's not rooted at all and has locked bootloader on the stock 10.3.5 ROM. Fresh out the box...just a few apps, some photos and texts.
I've seen stuff like this before happen with rooted phones but never on a brand new non rooted phone.
Fortunately (and with lots of prayer), I was able to let the phone battery drain out completely since it wouldn't power off.
Sunday morning, I plugged it back on the charger and to my surprise, I saw the battery animation only this time!
After charging fully, I turned it on and saw it bootlooping again. After 5 mins, I decided to remove both my SIM tray with both SIM and micro SD.
THIS time, the phone stopped bootlooping entirely! Again....what the hell was my question ?.
Normally, my nerves are steel but yesterday, they were more like spaghetti lol
Against my own judgement, I wanted to test if it was my own SIM card causing the issue or if my micro SD card caused the issue.
I placed the SIM try back in with each card 1 by 1 however, the phone immediately started bootlooping on it's own right from system!
I've never seen this before with any other phone or brand I've used in the past.
This activity occurred again and again regardless which card was inserted. With no cards, the phone worked normally.
I decided, you know what, at this point, I'm going to back up my data during and factory reset since now I have access.
Thank God that worked!
After many hours of backing up data, factory resetting my phone and then restoring everything on Mother's Day ( which meant working around free time and planned activities with my Wife), I am happy to say my phone is back working normally with the same SIM card and Micro SD as if nothing happened.
Fluke or not, definitely going to be watching this phone carefully to see if the problem is gone for good.
I will say this, when I first took the phone out the box last week, I turned it on and watched it update to MiUI 10.3.5. Normally I factory reset my phones after updates to be safe but since the phone was still new, I did not factory reset this time. That could be the reason it did this...I'm still not sure.
Sometimes I power my phones off, connect the charger and turn them on. For years I've never had an issue or doing it this way. For a few days I didn't have an issue with my Redmi Note 7 either. After this experience, I will stop doing that entirely.
My question is, have any of you encountered random random boot loops with any of your Xiaomi products? How did it occur and how did you fix it?

Got the same problem, fixed it the same way

Hello,
today I got the same issue as you stated above.
I tried to remove the SIM card (while the phone is on) and the phone brought me to the startscreen instantly. Inserting the SIM card caused the bootloop again ..
I googled this issue and found this thread,
went into the Recovery mode (Power + Volume Up) and did the Data Wipe.
Consequently, I could start the phone with my SIM card without problems ..
Later I found out, that removing the "Telephone"-permission from the "Contacts and dialer" app caused the bootloop.
(On my Stock 10.3.4 MiUI non root)
Greeting,
Dorian Rec

most probably removing the "Telephone"-permission from the "Contacts and dialer" app is causing the bootloop - remove SIM and data card, start phone, fix the settings issue the get back the SIM

How you solved this issue?

It's MIUI 11.0.1 still the same problem
Ok I updated my phone to MIUI 11.0.1 it still has the same problem but thanks to everyone in this thread I
finally fixed this problem that kinda scared the crap out of me.
Thanks Everyone

I did not know this was a thing until last night. I'm on MIUI 11.0.9
My phone restarted out of nowhere and then my flash light came on by itself, gps was turning on by itself and the reboot/switch off screen kept coming and going, little while later it went into the loop. wouldn't even get to the android screen, i couldn't go into recovery mode either it was so bad. I let it die last night and after seeing this thread i plugged it in, and took out the sim (no memory card). So it seemed to work, though the torch and reboot/switch off screen did show up but nothing like yesterday where it kept interrupting me while i was trying to backup my data. Luckily i do a manual back up regularly.
I changed the "Telephone" permission and it went into the bootloop immediately. It turned on, and i started to backup the last of my data and it went into bootloop again. It's been 10 minutes now.
I noticed it seemed to go into bootloop every time i turned off gps,cell data, or was clearing files from my phone. Honestly i thought i was being hacked. Any suggestions on what I can do?

It looks like a hardware problem, if your phone gets into bootloop even there is no sim card - try to change to the other position for the sim card

same issue
gosh scared the xxxx out of me too! I was uninstalling updates uninstall to my redmi note 7 cause too little space and it went into reboot loop. removed sim and giving permission works. I wonder how to do it if removing sim didn't help me boot! how would j have been able to add back permission. what's worrying was I didn't remove any permissions , I only did uninstall updates to all xiaomi apps

Seems like this problem exists on MIUI 12.5 too. I haven't tested the fix yet.
