My tablet turns off by itself - Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &

Good evening. As the title says, my SM-T820 turns off randomly. I've changed the battery and installed several official firmwares with no luck so I don't know what else I could try, if anybody has any idea please tell me.
Thank you so much
Kind regards.

I've had similar problem after trying different firmwares.
My solution was to go back to stock wiping everything there is.unfortunately I cannot really remember my steps, just be careful not to break anything, find a guide for this.
All I remember is doing some painful steps with Odin.

Thank you, I'll keep trying, if it's not broken by now I'm sure I'll not break it...
Regards

Mine also keep restarting by its own .. and freezing and turning off .. then I can turn it on without a hard reset ..
I found that power saver mode makes it longing till it restarts again.
Did you find a solution ?

I also had this problem. Mine was overheating heavily and restarting, then again overheating and so on. My way to fix it was to send it to Samsung Service, and unfortunately they said that they can no longer fix the device since parts are not available. So I asked them if they will exchange motherboard if I supply one, and they agreed but offered no warranty for such replacement. I got motherboard from aliexpress and my tablet started working as it should from the begining. The other issue I had with "old" motherboard was really high battery drain even when tablet was not used. It lasted like 2 days without use, now i'm charging it approx once a week.

[Q] Random Rebooting and Overheating X10

I had bought my xperia sometime around October'10 & updated it to 2.1 when it was available & then started facing this problem. The battery gets overheated, specially when charging, & when any activity is performed on the phone then, the phone goes into a loop of rebooting, stabilizing only when the battery cools off. Not only that, when on the move, apps like maps is initiated, the phone often reboots, so much so that it sometimes happens 4/5 times in a day, 2/3 times together. Since yesterday, the phone rebooted more than 10 times, twice with a sudden jarring sound while closing down. Also sometimes there is a burning rubber smell coming from the back of the battery. I have tried everything from reinstalling the android software to sending it off to a repair centre only for them to say that it is liquid damage when I know for a fact that no liquid has EVER touched it. Please someone help me. What do I do? Would downloading a custom rom or Zzdizus ne wcustom kernel help. Anyone got any working fixes
It sounds to me like a hardware problem, since you've reinstalled the firmware.
Why not, try zdzihus' beta 4 or wolfs' CM6.1.3 to see if it will be the same. But if it's the same, then you'll need a service.
I've had this problem too. I sent it to the repair center too (KPN Netherlands). But after 3 times to the repair center the problem still occurred. After the third repair I received a new X10 (with 2.1 pre-installed).
So I'm afraid there's no quick (software) fix. It's definitely a hardware problem and there's many people reporting this problem. Some get it fixed by having the motherboard swapped, some got a new phone, like me. I hope you still have warranty and manage to convince them is't not liquid-damage, because otherwise you're probably screwed.
I have this problem too, i don't think a rom upgrade will fix this, reading at different threads i am not alone with this problem, please read this:
http://forum.xda-developers.com/showthread.php?t=831658
I am going to get mine in for repair see if they can fix it, otherwise i am screwed.
Chances are services won`t be able to find the reason, and odds are good they will just hand you a new device.
Is there anyway whatsoever to stop the rebooting without paying for repair and without sending it to a repair centre (they keeps saying its liquid damage when I know its not). There must be something because this problem didnt occur when the phone was on Android 1.6 at all.
its not a case of roms or 1.6 vs 2.1 etc this is a problem which looking at the SE forums they know about however are not doing anything about
its a problem with the motherboard in about 1/5 xperias from what i read so not everyone will be affected but for those who are (tell tale sign being a burning smell when the battery is removed combined with random reboots) then the unit has to be sent back to SE for re-fit / replace.
however, and this is where the worst problems are, from what i read if the white sticker behind your back cover had red dots on (yes i know most peoples will just from natural humidity) but this is the water damage sticker and they wont fix it for free if this is marked (red dots)
also you need to have all the proof of ownership / warranty receipt to send off with it, so if your like me and got your xperia off of ebay they your screwed
sorry to be the bearer of bad news but this is the problem, if you have it its hard to get fixed and if you dont then good for you but the likelyhood of you getting the problem is not too slim not to think of taking out insurance
There must be something I can do though. The phone only started overheating when I updated to stock 2.1 so there must be something
This definitely sounds like the mobo problem that's been plaguing the x10. Sadly to say, there is no fix you can easily do without switching out the motherboard. I feel like the watermark sets itself off when the device overheats. Same thing happened to me, and I bought my first x10 overseas so I had no warranty. Your update to 2.1 probably just coincided with the issue starting.

What if I get zzhidzu's new custom kernel. It undervolts. Would this sstop or at least reduce the battery overheating problem
Please some expert respond
Because you're undervolting, it will probably not overheat as much, but it definitely will not solve the problem. The motherboard is already compromised. At first, my faulty x10 would only reboot once every few days, but as time went on, it became more and more frequent. Now, I can't even get it to boot past the carrier splash screen. Swap kernels for now, but plan to start saving money either for repairs or a replacement phone.

Does anyone have any fix whatsoever?
any at all? to at least significantly reduce the rebooting
If you boot your phone without a sim does it still happpen?
its defonatly worth a shot i recon ill give it a go also
Is there anyway I could maybe replace the motherboard myself or even do something to my phone to stop it from rebooting because of the battery? This way when I feel that its hot I can turn it off myself when I am ready.
There must be something I can do. The phone is literally unusable :'(
@Omega Red
It still happens but not really as much. But what's the point of having a ohine if you cant call lol
I have just switched back to stock 2.1 and my phone is behaving very well now.
Does anyone know how much it costs to get the moboreplaced outside of the warranty in UK pounds?

[Q] vibrant randomly turns itself off

Its been doing this for a while. I'll go to check it and it's off, but the battery hasn't died. Last night it did this so my alarm didn't go off for work this am. Everything is stock on my phone. N
stock everything so please don't ask what rom/kernal/whatever ..
Any suggestions? I can't be late to work again because this phone is for ****
If you are absolutely sure that your phone is completely stock, then the problem is probably your battery. Does this only happen when the phone is not plugged in?
It does it when its on the charger too. Like I woke up this morning and found it off but it was on the charger when i found it like that. i havent flashed anything or changed any roms or kernals which is why I say its stock. otherwise people ask me what rom im using or whatever.
It could possibly be a lose battery. Generally people will notice it when there is movement to the phone i.e. shaking it or dropping it. If the phone is completely still when it randomly shuts off chance are that a lose battery is not your issue. Still its worth looking into. Most people fix a lose battery with a small piece of cardboard wedged between the battery and case.
Good luck!
Probably not a loose battery. I just had it charging for the past hour and went to check it to find it turned off. Any suggestions as to why it happens when its just sitting there charging?
My phone did the same thing, and with my wife having the same phone I was easily able to rule out battery. Since your complety stock it sounds like a problem with the phone. If your with Tmobile give them a call and see if they will replace it, they did for me.

My phone is already a year old tho. i think my warrenty is gone,
(At least in my case) the warranty didn't matter. I had a 100% bricked vibrant and I told them that "it just happened" and no one was the wiser. I got a replacement and all I had to pay for was shipping. So my advice, tell the T-Mobile rep: my phone is broken through no fault of my own and I want a replacement.
Edit: that stuff happened like a year ago so I don't know if that policy still applies. Hope this helps though.
I did download Load Monitor and made the settings a certain way. so far it hasnt shut off. We will see if I am late to work again tomorrow.
even some stock Samsung roms (like kb5 and ka5) lately have had the same turning off problem for me as well. i think it has to do with some of the older vibrant's when the hardware (battery) becomes charged or is depleting slowly, triggers a software issue like a discharge error forcing an emergency shut-down to prevent damage. the only thing i can recommend it to take the advice of previous posters and get a replacement or upgrade if you are nearing the end of your contract.
just a few things to consider.
Have you tried, I know this sounds odd, a drastic ROM change? Not just switching between Froyo ROMs, but moving to a Gingerbread ROM like MIUI? Could help isolate the problem if it keeps happening under a different OS.
my problem is gone now that i use custom roms. the same could help you thread starter.
Edit. i know you refer to developers as op's but do you do the same to a thread starter?
Pretty sure OP stands for "Original Poster", as in the person who started the thread. Developers start a lot of threads which is probably why you thought it referred only to developers.
Since installing Load Manager my phone hasnt shut off by itself. Seems to have fixed the problem!

[Q] phone restarts

Hey guys you are probably tired of answering this same question but I will ask it anyways.
I was having a problem with my phone restarting constantly till it simpily wouldn't turn on, I got the motherboard replaced and now it still restarts constantly, I bought a new battery hoping that it might fix the issue and also went back to a stock rom and kernal to see if it was a software issue...
The phone acts up mostly when on the net with it... doesn't matter if it is pluged in or not.
Hopeing that maybe some of you might have some other ideas as to what else I can try, aside from smashing it into a million pieces, which I don't want to do as I really love this phone.
I had the same problem and I sent it for warranty and they changed the board.
Good luck.

Hardware or software glitch?

My brother bought a second hand SGS2 (I9100), and it has some weird glitch affecting the battery reading.
Even though the phone is fully charged, when the phone goes to standby mode (sleep), after a few minutes, or seconds, it suddenly "thinks" that the battery is not charged, so it turns itself off. When you turn it back on, is says we need to charge it, but after 15 to 30 seconds, it reads the battery properly, and goes back to the right battery %. If the phone doesn't go to standby, then the battery glitch doesn't affect, it doesn't say it is not charged, and it can be used with no problems for hours.
I've reset it to factory reset, but it hasn't solve the bug. We have tried also changing for another battery (I have one as well), but is not that, the battery is perfect (both of them). We changed the ROM a couple times, also changed the Kernel and root it, but the issue does not go away.
Can anybody tell me with the info provided if it is a hardware issue (hope not) or if it can be on the software? I've searched the forums but didn't find others with the same issue.
Thanks in advance for any help you can give us to figure it out.

While you're at there, resetting the fuel gauge chip a few times wont hurt either.

About 2 weeks ago, a guy reported a very similar (probably exact) problem.
After many troubleshooting, the problem was hardware related.

Dont wanna sound rude or anything, but s2 is still not a cheap phone (for most of people atleaset) , meaning,
when ur buying smartphone 2nd hand, the seller will have to agree on me turning on phone, playing with it for 20 mins, check everything and so on..
Display, RAM, everything, meet somewhere where is wireless so you can download android system tester off market etc etc
Because i am almost sure this is HW problem mate. I suggest you call him right away, and hope he still has the same number

Not rude at all! My brother review the phone, but didn't seem to have any issue at the beggining, started to fail like a week later.
We can return the phone at any time, is just that they don't have another one to give us right away, and most likely they'll take it for a review before we can get either a refund or another unit, so we wanted to explore all the options ourselves first.
I'm sure he'll be returning the phone soon as we pretty much ran out of options.

Thanks a lot Jokesy, you have been very helpful as I followed the thread and it is the exact same issue.
After a few days, the problem got even whorse as everytime is even harder to turn it on because it reads low battery. We can only turn it on, most of the time, through Recovery, as the key combination for Download Mode doesn't even respond. Sometimes doesn't respond at all. We just need to turn it on one more time to flash the stock ROM to return it.

Wow! then it is a hardware problem too. Since you said it will be returned, I think it's the last option too.
Good luck and hope you get a normal unit

Sounds a hardware problem so. You should change your defective battery. It is a typical problem of these devices.

is there an app or a way to test the battery health while the phone is charging? to make sure its the battery not anything else controlling the power in the phone

There are many apps for testing it, try some from the google play. But it would be better to find the Motorola's service of your area, because it might has problem the motherboard as well. I'm saying this from my experience.

the problem that motorola service in egypt "my area" will cost me more than the phone price .... thats why i wanna do it or test it myself
I have that problem for months. Changing battery helped me for 3 or 4 months. But it keeps happening. I'm having that issue "again" so if you have chance to buy another one do it. Save yourself and save your money for good. Cause you'll keep paying for battery after warranty and you'll say yourself "wow i could buy another phone."

I got issue, so i decide to buy new battery
Well done
Hello , this is due to android 7.1 update . Lenovo is responsible for doing this to us , it´s called programmed obsolenscence to make you buy new phones. This moto z is the cheapest vr ready phone in the market with a long long life in terms of tech , the only way is to buy a moto mod check in ebay (sept-2019) they are selling some for cheap from hong kong because a new moto mod battery came out with more mah.
I have had that battery issue before with a Moto Z that I bought in November 2016. The issues started around August 2017. When I had the issues I prolonged the use of the phone without replacing it by using a battery mod, but after some time it would power off even while on the battery, and would immediately power off the second I took the battery mod off probably a few months before that.
I eventually gave into buying a new battery for it and attempting to replace it myself. I rooted the phone first thing when I initially got it, so I didn't try doing official repairs since warranty was voided. Ended up breaking the screen in the process, ordering a new screen (had issues), and then ended up refunding the screen and just sending it into Motorola for replacement. The new 3rd party battery did seem to work without issue for the short time I tested it, so that may be an option, but might end up needing to be replaced in a year. The screen was really easy to break though.
I got a refurbished phone back and it is just now starting to show the same issues again (Replaced it March 2018, have not rooted yet). Had it abruptly die at around 20% earlier today. Not that bad but good to know that it may be starting to happen with this phone. This one I still have left plugged in every night, but without the turbo charger.
Debating on the next phone upgrade right now or if I just want to downgrade to a Moto Z Play I have laying around if it becomes unusable. I will still keep them around since I mess around with the dev kit, but not planning on getting another Motorola as a main phone if I get a new one.
