[Q] Screen won't stay off!

I can't turn my screen off. When I press the power button it goes off for 0.5 to 3 seconds and comes back on. I was using Axura when it first happened, but then I restored an older CM rom and I'm having the same issue. Has anyone else had this problem? I'm sure I don't have to add that it isn't ideal for battery life ..

Are you plugged in when it is happening? If so, have you tried to turn off the "Always stay on" setting?

I had this happen to me. It turns out it was a faulty power button. Its a hardware issue. I had to return my phone because I was still in the 30 day window, if you're outside of that you need to send it in to samsung.

Thanks for the replies.
Strangely enough the issue disappeared as quickly as it appeared about 6 hours after it began! I tend to agree that it's a hardware problem, but as long as it's not happening constantly I'm going to live with it (due to the fact that as an Australian living in Spain with a NS from the US I don't imagine a warranty claim would be easy).

A hardware problem wouldn't be my first assumption if I was on a custom ROM and/or had lots of apps installed.
If it happens again, I'd get a logcat recorder app or adb logcat session running on the phone and see what exactly it says goes on just before the screen wakes each time.

Oh ok. I tend to assume it's a hardware problem due to the fact that it happened on completely different roms. But the way that bug causing "artifacts" are sometimes left behind when changing roms doesn't give me confidence in that assumption. I really don't understand it.
I'll definitely give the logcat a go if it comes back. Thanks.

hi,
i am bringing back this thread from a few months back because it was the only one i found that showed the same problem.
i installed alogcat and attached a log file here. can anyone see if there's anything in the log that would be a software reason as to why it's waking itself? also, it doesn't shut itself off while this is happening. the screen will stay on indefinitely. i've had the phone for 6 months and this has become a new problem i would say in the last 3 weeks. i don't want to have to send it to samsung for a few weeks.
thanks for any assistance

Random reboot temporary fix?

So i've had random reboots starting on my phone recently and was thinking about ordering a replacement phone through LG here soon.
However, after speaking with a T-Mobile rep, they advised me that after hearing complaints about it, they've found (or heard of) a temporary fix for it, and it has seemed to stop MY random reboots too.
They're saying theres an issue with the software and the GPS crashing, a tmobile rep told me to just try and turn off the GPS option in the settings and, ONLY turn it on if its REALLY needed, and it should solve the reboot issue.
Now mind you my phone rebooted randomly about 2-3x a day. After following this very easy step, it no longer reboots AT all... and whenever i need GPS for anything, i just turn it on for those moments, then turn it back off.
( not sure if this has been mentioned before, but if it hasn't then give it a try, if it has then just hit the back button and continue on with your life )

Have tried that because I feel its probably partially GPS related too but I've had the phone reboot while GPS was off. I don't know if even using it for a bit seals your doom. What's weird though is I've never had a reboot while actually using the GPS including in Navigation for hours at a time. I think we just need a patch at this point.

[Q] Has anyone got a blank screen after moving around alot

Ive gotten it maybe 5 times since I bought it, although the latest updates have been stable. I still got it a few days ago though. Basically if I have the dock, and close the lid and say rotate the whole device or just move it a certain directions, it will make the screen stop displaying when trying to open it again. The lid opens, you hear a noise like it unlocks, but the screen is black. I try unlocking and locking, undocking, but its still black unless I reset the device via power. Anyone having this issue? It's not a serious one yet, but id like to know why it happens in the first place.

I have similar experience without dock.
I put it in carrying bag and drive to subway, when I take it out and the screen is blank and I can reboot it by power button. It happened 3-4 times under same situation.
I updated to 3.2 and problem didn't come back so far.

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.

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 !

[Q] Screen goes partially blank

Hey, so I have this weird problem with my G Flex 2.
I got it around 40 days ago from U.S. Cellular.
I have run into this problem about three times now, and from what I can remember it always happens when I have music playing. I tap the screen on to the lock screen then let it go to sleep or turn it off myself. When I wake it back up the screen is all black except for a few millimeters on the top, where I can see some display.(*note, this doesn't happen every time)
I am able to scroll through the display but no pop up menus. Since the battery is sealed off in the back of the phone I can't use that fix, holding the power button only brings up the menu option to turn off the screen which doesn't do me much good since I can't use the screen.
If I wait for 5 minutes or so the phone will right itself, but I don't want this to be a persisting problem. I'm not sure if this problem is tied to the music playing, it hasn't happened when it isn't playing, but I play music on my phone quite often. (note* I am playing the music from my phone, not streaming)
If you need more info I'll do my best to provide it. This is all I can think of right now.
Honestly, I don't expect anyone to have a fix yet since the phone is fairly recent and not as popular. I tried looking under G3 forums since the UI is pretty much identical, but I didn't find anything.
Sorry, my post is a little wordy.
I'd appreciate any help anyone can provide. Thanks

Yes, this has happened to me twice recently too. Once the screen was completely black except for a bright white line at the very bottom, but the phone was still responsive behind the dead screen. The other time there was a distorted/ghosty notification bar showing at the top but nothing else (like what you reported). Then the problem would resolve completely and spontaneously after resuming from sleep a few times. I have the Korean model (F510S) which was a gift so I'm stuck with it - no returns or warranty available.
bonebeatz1234 also posted about a similar problem. Seems like a hardware fault?

The replacement phone screen was fine i had a different issue of over heating and had to return it . I opted to get another device the note 4. Didn't wanna go that route bit had no choice i loved the design and ui of the flex 2. I wished lg would of just ditched the 810

Hi, I encountered same problem here.
Is anyone able to send me a screen shot or a video of this problem.
As I need to use this to prove the situation and claim warranty from the seller, however I didn't take a photo or something when the problem happened to me.
please sent to [email protected] if you have the photo or video and many thanks~

Just had this problem also had a g flex 2 for about 21 days now and it happened to me after a restart in the car with a pinkish line at the top and the phone was completely responsive even though the screen was blank
I think it might have to do with heat cause I held it by the ac vent while I was reading this board on my nexus and when I looked back at the phone it was working perfectly
But I swear during my time with the phone it heated up way more than this time and this time the phone wasn't even hot
I reset the phone like 3 times before I held it to the vent and it didn't help at all
Using the att variant with android 5.1.1

Have the same problem every now and then, found a recommendation on another website and in the instruction manual to reset the phone by holding down the power button and volume down button for about 10 seconds or to turn it off by holding down the same buttons for 20 seconds. I find what works better though is to just leave the phone alone and it corrects itself within about 5 minutes.

Having this same problem. Happens once every couple of weeks. Any updates on this?

I think that this is a heat problem....everytime i left my phone in the sun, it show me this strange error.

I'm not convinced its a heat issue. I looked at my battery chart the last time it happened and it was barely over 90 deg. It seems it happens to me when it is charging PLUS doing something like streaming music or GPS is on. I need to start taking notes. I should have done that before.

this have happened to twice too. weird anomaly.

Having the same random issue. Today it happened and reboot would not fix (it usually does) finally after about 30 minutes the screen came back to normal. I now disabled lock screen in case I need to get data off the phone from pc ? in the case that the issue becomes permanent.

although it's an old post, but worth to mention, that It can happen to all the LG Flex 2 models.
It is caused by a heat or inaccurate voltage. let me explain how it can happen:
heat - when you put the phone on the car's cradle under the car's front windows during a sunny day - it will happen.
voltage/heat - when you charge your phone and not using your original charger (eg chinese car chargers) - it will happen.
so what to do? I've noticed that putting the device over the cat's air conditioning , can reduce this to few minutes. also, if you can, mount your cradle over one of the air condition outlets and it will freeze your phone all the time
