Random turn-offs/reboots FRUSTRATION!

This tablet is a great piece of tech, however I've had two major problems with it. AMOLED screen burn-in and random reboots/shut-downs.
In the past week it's at least turned itself off or rebooted itself 9 times. Is anyone receiving this problem? Also in the past 3 hours or so, it's been rebooting to the Samsung Galaxy Tab 7.7 screen just before the tab turns on and gets stuck there. I managed to get out of that situation but I'm not sure how.
If you have problems list which version of the tablet you have, your firmware or kernel version and your specific problem.
Hopefully we can get Samsung's attention if theres enough people and have this patched with an update. Or maybe it'll all go away with ICS... just being optimistic lol.
If anyone knows any sort of customer service or someone from Samsung I can email about this problem that'd be appreciated.
Details:
GT-P6810
32GB WIFI Only
2.6.36 P6810DTKL5 Rooted.

I don't have the problem but if I can maybe suggest, have you reset the device back into factory setting?

Your not the first one to ask this nor your alone, this also happens with the Galaxy Note with some users, I've never been able to pinpoint the cause for this on the note.. I'll see if it happens on my Tab7.7 when I get it tomorrow.

Do you by any chance have a sim card inserted? I noticed yesterday as I was working with AT&T to get my device set up that each time I had to take my sim card out (to give them the serial number) the Tab would reboot on its own.

I have had 2 reboots since getting my tab, very weird.

We need more people to chime in and see how wide spread this issue is, it could be cause by a very aggressive deep sleep state that is used by samsung?

I thought that factory resetting it would help but as far as I can tell it hasn't. I tried that about a week ago but am willing to give it another shot if someone proves me wrong. Thanks for the input though.

I have the wifi version so I don't have a sim slot. Sorry for not being more specific in the opening. Although I remember someone else mentioning that their sim may have been the problem. Thanks anyway.

Maybe something with the processor, they're relatively similar aren't they? Anyway hopefully I didn't discourage you from your tab, it's still one of the best pieces of tech. Lets hope this problem isn't that widespread and if it is lets hope for a patch or something, maybe with the ICS update hehe.

Have had my GT-P6800 for about a month and I have had several random reboots -- since the reboot is complete and I end up where I was I cannot determine what's behind it.

Haven't had reboots, but I've ran into issues with it turning itself off at least once a week. Currently on LA2 firmware.

I had about 4-5 reboots in a week . don't remember details .

Is everyone using 3G card that are having reboots? I did NOT have any reboots until getting a 3G card this weekend. It JUST did it. Also, I notice if it's on charger (not USB) that when it's full it will more likely reboot. That's my $.02.

My 7.7 p6800 has not exhibited any reboot. I am on KL1..but it has prompted me to update...

I just got my Tab7.7 but I do not have a spare simcard yet to test if its causing the issue but I will update this post for any findings

1 Sleep of death so far, watched a movie but locked the device to take a phone call from another phone. Had it in flight mode but wifi enabled.. so thats about 24hrs from initial power up.. I also performed a factory reset before using the Tab.

yep, my tab prompted me to update as well, I it yes, it downloaded something over wifi, then it rebooted, then it goes to recovery and installed the new stuffs, then said "failed" lol
I only have one crash that is when I used the cam then hurriedly hit back several times, then it froze and rebooted, that's the only time it did it

I've structured the OP a bit better hopefully. I've provided my details and asked people for theirs.
Going to go look for who to complain to now lol.

No reboots yet but I did see it wake up to the lock screen while it was sitting on my desk, I have it in flight mode if it matters. It was actually spooky..

Ok I just had the sleep of death on my Tab7.7
Airplane mode but wifi is enabled, the last thing that I was doing was watching a movie and locked the tablet to take a phone call on my other phone. No SIMcard inserted only a 32GB microSD card.

Hi all.
Got my tab 7.7 3G about 3 weeks ago. Rooted on day 2 (this is my 4th droid so pretty confident doing so.... but...) using the simple root method posted somewhere here in XDA.
Not sure if this is related to the rooting, but I've had about 6-8 reboots, several shutdowns and one really strange rebooting which led to the tab unresponsive to anything (only showed the samsung name logo). I was about to factory reset again (I did about a week ago but only because I forgot to reboot after I rooted) when the tab suddenly woke up and started booting normally.
Normally until apps started loading and for almost all the apps, errors of some kind started popping up.
Since I had control again, I factory-resetted the tab.
Since then, I've had no reboots or shutdowns. I do not know why.
Other strange quirks - sometimes, when waking the device with a quick push of the power switch, the screen does this strange graphic swirly thing (almost seems like a graphic image gone mad while loading) and then loads the proper graphic/lock screen.
Sometimes too, when changing orientation, the graphic seems to lag behind the action. Not all the time though. I use Go Launcher as my default but I've noticed the TW screen do the same thing when I change orientation.
As far as Go launcher is concerned (I use it as well on my GS2), only the dock seems to have a problem - when flicking from one dock to another, the next dock does not 'center'.
So far I am a bit disappointed and hoping (hugely) that ICS releases this tab to its dual core, SAmoled glory.
Edit - if I were to say which was the biggest disappointment, that would be the media rescan. When I have a new photo or image, the image does not appear right away in Gallery. When I try to use the music player, the player will not load (rescanning) but the image appears in gallery after.

Hm, mines rooted too. I wonder if that affects how often you get a reboot/shut-down? Still, it better get fixed with an update.
Btw, don't use this tablet as an alarm. I woke up half an hour late to find that the tab was off. I turned it on and the battery was at 60% so it definitely wasn't the battery running out. Maaan was I late for school lol.

tab 7.7
I have the same problem especially when watching the movie or downing torrents after the screen shutdown especially when the battery over 50%. when I want to switch on the screen, the tab will not response until long press on power button switch on with galaxy tab 7.7 screen. that means it was shut off !

Nexus 5 Screen Freeze

Was at about 30% battery and the screen froze as in it wouldn't take any touch events. The backlight would react as if the screen wasn't touched. It seems like the touch events just were not registering but the phone worked in the background. Kernel issue maybe? I have been using faux.

Something similar ....
I had a similar experience on the 15th .... took my N5 off the Qi charger and the screen froze when i tried to unlock it.
I hit the power button and was able to unlock and get a few touches in before it froze again.
I was finally able (after much screen off/on cycles) to get down to the developer options and turn on show touches & show cpu usage.
... background processes looked fairly normal when the screen was frozen(touches showed as frozen) ...
I was rooted, stock rom except for xda user Jishnu Sur's N5 camera mod and running a couple tried & true root apps(Stickmount & QuickBoot). Thought some software issue might be jamming up the digitizer i/o causing it to freeze.
Reverted entirely to stock (the Team Win recovery was also experiencing screen freeze - buttons worked fine) including removing TRWP and re-locking the boot loader!!
The screen freezing problem persists ... my conclusion is that it's a hardware issue. :crying:
It's possible you are seeing the same thing, but I haven't seen anything in the forums to indicate it's a widespread problem.
Returning it for a replacement phone ... :fingers-crossed:

Hi,
same problem here from France.
I already returned a Nexus 5, after multiple freeze I tried to format data partition via bootloader, (no rooted phone, following google instructions for stock reset) then the phone crash wile formatting, it never wake up gain.
When I get a new one from google after one or two week same problem appears, and it's append more and more often, since monday my phone crash one time more every night, and all the day today.
A this time I'm still trying to load it sine I came back from work seven hour ago, battery still at 49%.
I think it's and hardware issue too.
I'm very disappointed about Google and I'll never by anymore LG products.
Thanks for reading.

Freezes tend to happen on custom kernels specially if you under-volt it too much. have you done that?

Last week I had the same problem with my new NEXUS 5. IT’S TOTALLY A HARDWARE ISSUE.
LG products are however not so bad in the JAPAN market but still we are expecting a lot from LG technology.

LG services suck.
I am facing the same problem with my Nexus 5. Unrooted, bought 7 months back from India itself, was working fine till around two weeks back,when the lags, screen freeze, blacking out n all appeared. Got it repaired twice at the LG centre. They changed the front display touchpad as well as the charging connector strip. The problem still persists.

S7 Edge freezing then restarting

Hi all,
Hope somebody can shed some light on this issue I'm facing. This is my first ever post. All your input will be very much appreciated.
I purchased this S7 Edge DUOS (Dual sim version) around 8 weeks ago. Around 3 weeks into my ownership, I've started facing a persistent issue which I've tried to resolve with the best of my knowledge but unfortunately I haven't succeeded.
Randomly the phone will freeze for around 5 to 10 seconds and then restart. Sometimes a pixelated set of lines would appear across the screen when it freezes, a lot of the times they are green.
When the phone does reboot and I return back to the main screen, everything is back to normal and the apps I was using remain opened in the background, so it's not a proper reboot.
There is no such pattern on when this happens, it happens while being used on any app and a lot of the times it reboots while the phone is in my pocket. The only reason I realise is because the phone will be on the startup lock screen.
Battery life seems okay, nothing seems to be draining the battery. Although sometimes it does get hot and drains it temporarily.
I have cleared cache partition, done a factory reset and deleted third party apps. Nothing has resolved the issue. When I did the factory reset, the phone didn't crash for a good few days then started doing it again.
I just cannot work out what it may be and it's getting really frustrating!
I really hope somebody can shed some light on this, I am trying to avoid going down the return route.
Many Thanks in advance for all your help.
Hassan

Hi my mate had the exact taste problem with his s7 Edge single dim version, it woody of freeze and reboot and pixilated just as u explained and turned out his phone his cpu overheated and this was the result of it, he then returned it to Samsung and he received a brand new handset so best is to maybe return it as it sounds to be a faulty handset.

Problem with WIFi

Hello,
I have a problem with my both Mate 9 devices.
The Mate 9 lost for a second the connection to the WiFi.
I have this problem onlny in my WiFi.
Other devices works fine (Pixel Xl, Iphone, Samsung Tab S).
Have someone a tip ?

Can you explain more about your problem? What happens when you turn wifi on? Does it just turn off after a few seconds?
Have you tried a soft reset?
Sent from my MHA-L09 using Tapatalk

I'll hijack this thread with my issue I guess. I have a mate 9 about 3 months old. After a period of time, WiFi will drop, but I can't actually switch WiFi off, the toggle is just frozen. It feels like a frozen process because other things can't close after this. I also can't reboot the phone normally using the menu when holding the power button. I just get the symbol for 'busy'. I have to hard reboot my phone, hold up volume and power.
I'd love to see if a fix could be done without needing to take the phone back as I don't have a spare phone atm so taking it back for warranty stuff is bit of a problem. Lots of thanks to anyone who has read this, and huge amount if anyone knows of a possible fix.

First, back up everything with HiSuite and do a factory reset. It seems like a software issue but hard to say. If it's still there, it might be a hardware issue, which would have to be done through warranty. If you're a bit more advanced you can wipe everything out and flash fresh update files from Huawei and start completely from scratch. All the info about doing that is on this forum. If a factory reset fixes it, you should consider unlocking the bootloader, rooting, and disabling all the bloatware that Huawei puts on there as I'm sure it would cause lag and issues like that after some time.

If the wifi signal is very weak, it will change to mobile aggressively if the option Wi-Fi+ is selected. I'm not sure if the other Android devices have this or not.

Dear waz i am with you on this. I tried to hard reset and reflash the rom. When i uninstall play service updates i dont see wifi issue again but then most of the apps do not run. And when i let it update itself allof a sudden i start having issues wiht my wifi connection and i cannot even restart it because it gets frozen. What rom are you uskng?

Hi. As I mentioned in the PM reply, I did a factory reset as deleting "a few apps" didn't help with the problem. So I'll know more in 2 or 3 days if no issues occur or not. Hoping it's fixed

Well, a factory reset has got it working fine again. I haven't had the WiFi drop for the past 2 or 3 days since the reset. Looks like it was software influenced indeed, sweet!

Large delays coming out of sleep

I have a very weird issue with my HTC U11 plus:
When the screen is off (the device is asleep, not turned off), pressing the power button or using the fingerprint sensor turns it on, but there is a random delay, between 5 and 20 seconds, where the screen stays blank.
Additionaly, the Edge Sense is absolutely unreliable: there is again a delay of between 5 seconds and 35 seconds.
It has started doing that last week.
I tried factory resetting it today, but I get the same result. I have opened a ticket at HTC, but as it is out of warranty, I don't think they'll be able to help me...
Has anyone ever seen such an issue?

Did you solve this？
I have this problem too and my camera also have delay when i open.
I tried flash the stock RUU,but it's no use.?

No, unfortunately not. HTC support said they could repair it but as it was out of warranty they gave me a quote for several part replacement they might have to do, and it cost the price of a new handset (500 euros for a motherboard replacement) so in the end I went with a new handset

It's so unfortunately.?

I have the exact same issue and from the last weekish or so, and no luck fixing it or finding out what is causing it. Also tried factory reset, safe mode doesn't help. Randomly its ok at times but typically 5 seconds to wake from sleep mode. Ive done no system updates. And yes camera is affected, almost feels like CPU tied up doing something.
running android 9
software 2.20.709.2
kernel 4.4.153
It must be an APP issue causing this, does someone have the issue on a rooted device to see what's using the CPU. Once its out of sleep mode for a bit its all ok and runs normal.
---------- Post added at 02:42 PM ---------- Previous post was at 02:11 PM ----------
Hi edzilla,
Did you try another ROM, or does anyone with the HTC u11+ not have this issue and if so what ROM/stock version are you on?

I believe I was on the latest update when it happened, and that that there wasn't any update before it started happening.

ill try rooting/aftermarket rom later to confirm if its hardware.

i downgraded back to android 8 RUU and the issue is still there. i have not tried non stock rom yet but this seems like a hardware issue with the screen or CPU once its in full sleep mode. is anyone running a decent alternative rom i can try?

Anybody found a solution? Like with a different ROM? Or confirmed it is hardware?
I have the same. Came out of the blue. First it was draining the battery. That has stopped now. But since a couple weeks, huge delay when starting. Up to 25sec.
Thought it was an app. So did a hard reset, wiped everything. But even without any apps installed, still the same delay when starting from standby.
Android 9
software 2.19.401.2
kernel 4.4.153
Is it worth putting a different ROM? Don't want to waste a weekend...
So maybe better directly getting a new phone? Any thoughts?
Thank you!

I couldn't find a good rom to try and never found a fix for the slow wake issues.. still happens in safe mode so not an app. Most likely hardware.. gave to my daughter who can deal with the issue better than me.
