p5200 Random shutdowns

Hi all,
I own the p5200 (Tab3 10.1) for a few weeks.
Recently I noticed that the device sometimes randomly shuts down by itself, and I have to power it on again by myself.
It mostly happens when I don't use it (and than come back to use it and it's dead) - but it also happened once when I used it.
Did any of you guys experience that weird behavior ?
I don't believe it is a hardware defect, rather then a software/kernel issue (maybe even the previous generation's SOD problem?)
Appreciate any help!

The problem seems to be getting worse, now it happens a few times a day,
I read some and thought it may have to do with the Sleep of Death.
If anyone knows anything about it I would be more than happy to know,
Thanks,
Matan.

Are you running stock? Are you rooted? Need more information to try to lead you in the right direction.

Thanks for the reply,
I'm running stock unrooted/modified XXUBMI5 firmware.

Hi,
same/similar problem on my P5200/10", stock not rooted firmware 4.2.2 - after cca a month of using random switch-off started, after another few weeks it was more and more frequent and the tab was usable only very hardly. my quess was some HW error like bad battery concact, as it happened mostly during tab movement/shaking/turn arounds etc.
Sent back to vendor to reclaim, back after a month with factory reset and message "problem not reproducible". and really, it was not happening(!)
Another week or two has passed since then - and random switch offs are again back, now also when there is no movement (i.e. overnigth). I am planning to try to save some logs to find why it happens (some bad application?) or at least to prove to vendor it really happens. then I will try also another factory reset (however, I do not like to setup it again and again and backup/restore might not work, if it is caused by some app ).

When this happened to me on a previous device, it turned out to be SD card related. The SD card would unmount and that would apparently freeze my tab, usually shutting it down. Then again I was using a swapfile and had most of my apps installed to the SD card. But I figured I'd mention.

thanks, but I have no external SD card inside, there is just the internal one, which is not removable.

Hi,
Same here - no SD card involved.
I can update that "somehow" those random shutdowns did not occur in the past few days (where before it happened a few good times a day)
I can also say that when the device is connected to a charger no shutdowns whatsoever.
Also, in the past few days battery is draining much faster than before.
Personally I think it is the battery, October's bad battery batch of the S4/S3 reminded me that this could be the issue here as well.
Tried to look online for a battery replacement to buy, but without any luck so far.
alfi_ , if you have any new info I would very much like to know
Thanks!

Hi,
so far nothing special - as it does not happen while on charger, also log via USB is useless. and the log via TCP is empty.
what I have seen in discussions / heard from more experienced people, incl. the branded service partner, it can be often caused by some additional application (for me its hard to believe. and if the same happens to PC computer, it will definitely be a reason to return the device). but anyway I would suggest you to make a backup and try the factory reset too. then test it for some time without any new installed application.
for my one it looks little better after reset (weird behaviour), but it still randomly shuts down. then I am going to visit a service center personally to present there the behaviour, but it may take some time..

Hi,
the problem was reproducible also in the service center with factory setting without any other application installed, so after a month the tab is back with replaced mainboard (part gh82-07643a) - and so far no problem. hopefully it will not repeat anymore

I've been experimenting the same issue. Sm t311, stock unrooted rom.
It happens when the device is sleeping, it just fails to come back.
I've seen it happen with and without sd card, with and without power cord attached. It doesn't seem to be related with the sleeping timespan either.

one, maybe useful info when this happens, which I was not aware of - androids v4.1 and newer have the possibility to boot into "safe mode", where all additional installed applications are disabled. so before you try factory reset and reinstall/reconfigure all applications, you can try also this. (I am wondering this option was not told me by the service). on tab 3 10" you can reach it while booting and the logo is shown, press and hold both volume keys.

battery terminal
I seen a post somewhere that samsung forgot to secure the battery terminal, on some tabs. I have the pics of the teardown, in case I ever needed them. I'll post a link. https://www.dropbox.com/sh/rg53ls0004rgdjr/ARJ-ecv2NA/teardown (1)

Here is the original post http://forum.xda-developers.com/showthread.php?t=2593766

After troubleshooting this issue and discarding possible causes such as charching problem, smart cover side effect, defective sd, etc etc, I had given up on my T311 and decided to start experimenting with some custom roms (after all, it's painless to brick a defective tablet). Somehow, after flashing FastDream the issue disappeared.
It has run for 27 hrs straight without turning itself off.

Hi, I have problem with my Galaxy Tab 3 10.1 gt p 5200.
Tablet without noticeable reason began randomly shut down by itself.
Sometimes in an hour goes off 5-6 times, and sometimes working 5-6 hours without turning off.
Tablet can not be sent to the service because it was purchased abroad.
On it is the original untouched Android 4.2.2.
I tried a factory reset and re-flash with the latest android from sammobile.com , but it didn't help.
Does anyone has a similar problem or solution.
Thanks in advance

Rebooting every few minutes - my tablet now resembles a potato

Hi all,
I have a vanilla, unrooted tablet which had Marshmallow installed a few weeks ago. It reboots constantly (like I am lucky to get 2-3 minutes out of it). Sometimes it reboots 7 or 8 times in a row until I give up and hold the power button down.
Have cleared cache and factory reset (multiple times). This hasnt solved the problem. I thought this might be an issue with the Google Play Store, as it generally crashes as soon as I run this (as the first thing I do after the reset) - so after one of the resets I downloaded the latest playstore APK and installed it. Also did not login to the play store in case this was corrupted or something. Have tried this without loading ANY apps other than the stock that comes after the reset - but still the issue persists.
All of the above has been done with the SD card removed - and with full charge
Generally it crashes as soon as I try and run any app or go to settings etc. This is even with the completely factory reset and wiped tablet with no additional apps installed.
Having tried everything, am down to the theory of hardware fault - specifically the battery. After the last update (which failed half way through) I had big problems with battery life and the tablet got (and still gets) quite hot. I am thinking something in the new update might have put extra stress on the battery, which after a few weeks has caused it to fail.
Is this possible, and is there anyway in logs etc to tell if this is hardware or software?
Anyway, other than throwing this away and buying a new one - am not sure what the next step to solve this is. (Maybe revert to previous Android?). Any suggestions or help is welcome, but I am thinking of throwing this away and not throwing good money after bad...
(Have emailed Samsung but of course never heard back - so suffice to say my next tab wont be Samsung)

try download your stock firmware and flash it with odin via your pc.

i had problem with my tab...i had restarts always...whatever i do, every few seconds it restarts by itself... but it works normaly on cable so i went to search for a solution and lol i laughed when i saw what was the solution...i removed the backcover fo the device and then just reatached the battery connector cable and thats it and now my tab works normaly even on battery.not sure if u have similar issue but u can try it it will take u 5 min work and also u have video on Youtube how to dissambly galaxy tab S...cheers mate and wish u good luck

I solved this prob yesterday, itb works fine nw, didnt crash since, just open the tablet remove the basttery vlean its pins then reinstall it
U can find vedios explaining hw to remomve z battery

OK - have updated firmware with ODIN (and tried 3 different versions going back to Android 5)
Have undone the back and removed battery and reset cables. Even replaced the battery with one I bought off Ebay
Cant think of anything else, must be a fault on a board somewhere...
I think she is dead. :crying:
Thanks to those who posted and sent me PM's - really do appreciate it.

By the way, it is definitely something to do with the power. When it reboots and it is attached to a USB, the screen flashes up with the empty battery (ie charging from completely empty) symbol momentarily (maybe a second or 2 tops) before flashing up with 64% or whatever the actual battery level is...

If your battery can go from 0% to 64% in a few seconds, the battery connector needs to be resoldered due to cracked solder joints.
This rework only takes 5 minutes , ask a repair shop or anyone knows how to solder for assistant.

Random Reboots?

I was just wondering if anyone else has an issue with their Note 4 rebooting randomly with no external input. This started happening with the Android 6.0 update both on the download from here and the AT&T official release, Any Ideas? I've already purchased a new battery due to a separate issue, any idea?

I had the same problem. The phone would freeze and randomly reboot. Sometimes the system crashes and asked me for the typed-in password (not fingerprint). Sometimes when I charge the phone, and unplug the power cable, the charging led stays lit and the battery has to be pulled. I decided to switch the battery with my wife's Note 4 and see if the effects remained. So far I haven't had any problems after switching the battery, so I believe the battery may be the cause of all these issues. I'll keep you updated on the issues.

I'm back. The battery replacement didn't fix the reboots. I think my phone's hardware is permanently damaged. :crying:

its something completely different to this topic

I've been having the same issue, started about 2 weeks ago. phone would start being sluggish then if I continue tapping on screen, it'll reboot. At least once I saw it go into recovery & reinstall firmware(?). Another time it just sat at the bootloader screen waiting for software download or something till I took out the battery. Most likely it's a software issue related to 6.0 update or updates afterwards. taking out the SD card helped a bit.
but basically got annoyed & upgraded to LG V20 today. Coincidentally, there was another person at the AT&T store with a Note 4 having the same issue.

Mine just rebooted twice on me a while ago, first is emergency calls only now the reboots then what. And yes the slow charging is a problem too. MM got serious issue dam att

use wakelock its an app u get it from play store.it makes ur cpu always running.some how it fixes the problem of random reboots. dl it and set it to partial lock (the 5th option)

Same problem. Just started a few weeks ago. REALLY frustrating having to enter my password every 3-4 minutes. NEVER buying another Samsung, too many damn issues with this phone.

My reboots tend to happen once the phone goes below 60% battery. It's fine above 60%. Once it goes below 50%, the reboots tend to happen with any intense network activity. The phone will often go from 50% to 22%. I forgot what the 30's and 40's look like. I will try the Wakelock app.

Ugh. I posted about this a few weeks ago. It's started happening more frequently and will occasionally go into a boot loop or show 0% battery even though there's a charge.
Has anyone found any solution? I haven't tried wiping / resetting but I'm getting close to trying it.

Here is a cautionary tale for you. My completely stock, unroooted phone started acting the same exact way. On the 4th or 5th battery pull (to fix a frozen screen) it just crapped out. It's totally unresponsive. Deader than a door nail. Tried everything. The download mode, discharging by power button depression/battery removal, etc. Adb shell command does not detect it. Nor Odin. Computer throws up a qhsusb_bulk error when I plug it into pc. I have NO CLUE how to fix it & I am desperately seeking a solution. Please proceed wisely with your oddly acting phones & don't let this happen to you.

Same issue. Just got off the phone with Samsung support, all possibility of having this particular phone with this particular issue sent in for evaluation has been suspended. Translation, they know it is an issue and will not stand by the changes they push to their products (latest OS). I am researching the prospect of legal action since THEY pushed the new OS against my request. Shouldn't that affect the warranty or coverage? Consulting my attorney friends as we speak. Will let you know. I am not sure how WakeLock will help, it is not going to sleep, it is repeatedly power cycling through a kernel process until the battery overheats or it reboots.

Same issue
Since Marshmallow, my 910A will get sluggish or freeze, shut down, sometimes reboot and sometimes just brick (temporarily). Sometimes--more often in recent days, I get a "dll_mmc read fail" message and the target that says do not stop downloading. No matter what I've tried--factory and soft resets, cache clearing, battery pull, replacement, and SD card switch, contacting AT&T and Samsung rep--it doesn't seem to change. This is a daily issue and becoming more frequent. Any suggestions or do I just need a new phone? Thank you.

Note 2 keeps restarting everytime!

Hi guys. A relative asked me if i can repair his note 2. I think his network was locked and the phone keeps restarting everytime. I flashed a new firmware on the phone. The one I use on mine..XXUFNG1, and also I went into recovery and clear data and cache after flashing. But still the phone keeps rebooting everytime. Why is that and how can I fix this?
Note : It's not bootloop or anything. You can switch on the phone, use it for like 5mins and then it freezes and restarts itself. And it goes on like that. Sometimes it doesn't restart also and you can use for more. But most of the time after 5mins, it restarts.

Was the phone dropped or exposed to moisture? Possible battery problem? Reboots even when connected to a charger?

Hi..thanks for reply. I tried another battery in it. The one I use myself. But it still restarts. I don't know if the phone was dropped or anything though. The relative just told me that it needs to be unlocked. Do you think it's software related? Or something is damaged in the phone?

Since it is running a stock ROM and still behaves this way after a factory reset, I think there is a hardware problem.

I might have a similar problem. I copy from another thread:
Hey guys,
I like this rom so far. But since 2 weeks I got an issue.
My phone randomly turns off, atleast I guess that's what happens. Sometimes the "notify" LED is on permanently but the display won't go on. To start the phone again I have to put out the battery and put it back in.
My battery is randomly empty pretty fast even if I just let the phone turned off. This happens like every 5 minutes.
I already bought a new battery but the problem hasn't changed.
What to do now? :>

I like the phone. It's over 5 years old and runs like the first day. Except it DOESN'T wake up anymore after a short time when the screen is off. I can press the power/home button as many times as I want and wait for 5 minutes, screen will still be off. Only way to "wake" it up again is to put the battery out and in again.
Currently I don't have enough money to buy a new phone and I can get a new motherboard for 25$. But I'm not sure if this will fix my problem.
I'm not even sure if this is the ROMs problem since it worked with all earlier versions of this rom perfectly and even the latest release worked for weeks/months.
Click to expand...
Click to collapse
As long as I leave the screen turned on the display/phone won't go off and I can use it as always. Even the battery don't drop drastically then.
It might be exposed to moisture tho. When I take a hot shower I'll leave it on the window sill and the room gets steamy.
ROM: [7.1.2 r24] LineageOS for N7100 [Unofficial] - Version from 08.10.2017
GAPPS: Open Gapps ARM 7.1 Aroma - 03.05.2017
Baseband: N7100XXUFND3
Ril and other stuff I don't know where to check.
Some years ago I had the SDS and the motherboard was changed without the EMMC bug.
Sometimes my phone only charges in slow mode too.
I try a clean install and newer pico gapps now. Maybe it will solve the problem. I'll reply then if it worked or not.
[EDIT]
Since my phone was low on battery I turned it off completly and put it on the charger. After an hour or so I wanted to look after it.
The green charging light stays on and if I want to turn the phone on nothing happens. The light stays on even after removing the charger.
Seems like a hardware, not a rom problem? Will changing the motherboard fix this?
[EDIT 2]
Quick update. I fully wiped/factory resetted and clean installed newest version of this ROM + newest mini pico GApps. Still the same problem. Gonna try it with another ROM/kernel now and if the problem persists it's a hardware fault.
[EDIT 3]
Fully wiped again and changed ROM+Kernel. Still the same problem.

Random and untimely reboots

Hello everyon everyone.
I have the SM-P600 version, everything was good until the beginning of the week when touchpad began to go off without reason, and completely random.
I first reinstalled several official ROMs from the most recent to the oldest, with no significant improvement
Then i rooted and tried Lineage, it looked good for a while, but in the end same problem.
Please note, when the tablet begins to mess, the reboots are occuring more and more often and after a while it turns in a loop and im not even able to switch it off.
Samsung logo display, black screen, logo, black screen, etc ...
I think rather for a battery-side problem, if some people have faced similar problem, I'm taking help.
Do you know if by chance we can use the tablet without battery to test this theory?
Thank you in advance for any answers.

I think I'd be taking a close look at the physical power button. Seems to me that if it had gone flakey it could cause something like this.

Hello and thanks for you answer,
Just to precise i never faced this issue while flashing an official or custom ROM, dont know if it is just luck or it can help in anything
Anyway ill try to check it the power button just in case

It's weird I just started having this exact problem myself. One morning I unplugged it and it had shut itself down overnight. Since then it randomly reboots. Sometimes I can get 20/30 minutes out of it, but once it starts, it can get into multiple reboots with the only way to stop it is to plug in the charger. I tried wiping cashe/dalvic (no help). Nothing was recently changed (including apps). Tried resoldering battery connector (battery was replaced a year or so ago with OEM Sammy). The P600 is rooted with TWRP installed, but no custom ROM. Usually the reboots start while I'm doing something (surfing, email, etc.), but I don't think it will do it while sleeping. I'm considering the power button, but I don't see this exact problem anywhere else, but this post. Any ideas?

OK. My tablet has taken a turn for the worse. Now it is stuck in a continuous boot loop. I tried the power switch, no help. I tried booting into TWRP, and it went back into rebooting before I could do anything. Strange thing is I can put it into download mode indefinitely without it rebooting. Should I ODIN back to stock? I tried the resoldering of the battery connection earlier. Any other ideas?
