Hi all,
I have a rooted "g'Five President G9(Android 4.2.1)" smartphone. I'm facing a strange problem:
If I turn my wifi+bluetooth off and touch anywhere on screen, its display disappears and shows a very dim grey screen. Then until and unless I don't turn my BT/wifi on again, its display won't get back to the normal state(shows a grey screen). When that grey screen appears, I still receive notifications for calls and messages. Even I can respond to calls because I have an estimate about where to touch to answer it. I can also lock/unlock phone thorough that grey screen (which means mobile is not stuck). I have tried restarting phone, but in vain. Please provide some help in this regard.
I can use my phone easily if its wifi/BT is on(but it drains battery with a vigorous pace). I haven't performed any tricks with my device in recent months and I'm facing this problem since last week.
Any help would be appreciated.
Thanks.

Hi all,
I'm having a problem with my sgs2 that I'm unable to solve.
The problem is that sometimes, not always, my phone does not enter sleep by itself. Infact it doesn't lock itself either.
Also, again sometimes, if I have a missed call alert or text the display lights up but then stays lit sat at the lock screen.
I've done some testing. I have tried different roms and tried the stock Samsung tom without modifying any settings and the problem remains.
If the phone is in my pocket then it can be a while before I notice. Today this happened for about an hour before I checked my phone. The phone was hot and the battery level had significantly dropped.
I've also noticed that with sound and vibrate switched off, sometimes when receiving a call the phone vibrates for 1/10 of a second. Everytime this has occurred the screen has stayed on after lighting up for the call.
I have wiped the user area on my phone but note this did not delete my music and pictures. Is this correct?
Any ideas? I'm really stumped and it's ruining the phone for me.
Thanks.
To see what apps/processes are causing the device to wakeup from deep sleep download and install Better Battery Stats and see under Partial Wakelocks.

Hello,
the following problem appears when i try to unlock the phone after some hours: i can see my home screen, but the screen stays extremely dim. When i try to start an app (e.g. browser) the screen turns black. I can unlock it again, but the screen stays dim. after some unlocking the screen becomes normal (normal brightness) and also the apps are startable.
i am using autobrightness, the stock firmware, 4.1.1 (i9300xxdlih) power saver is not turned on.

i updated mobile phone to android versiopn 4.1.2. this morning. Unfortunately the problem still appears.
Maybe its a hardware defect?
Try to disable somehow light sensor and change settings to non auto brightness.

i disabled auto brightness and set the brightness to the highest level. But its still same: very dim and after a while a black screen; after a few times of unlocking, the display works normally
I have just seen the same issue on a friend's S3.
Anyone else? I feel like this is a very big issue that is still lurking in a lot of devices.
I tried it myself and I toggled the power button to turn the screen on and off.
It doesn't take long but sometimes when the screen turns back on, it's super dim and you can faintly see the lockscreen image.
You have to cycle the screen several more times to get it to the 'correct' brightness, and no it is NOT a brightness setting.
It's some hardware issue in the phone.
Sorry for the necrobump, but I only found this thread. I have this problem too since about a week back. It makes my phone useless at times. I first thought it was a software issue. I have an app (called Twilight) for dimming the screen more than normal settings and also toning it, for nightime use, and I thought that was the culprit first, but nope. I have flashed rom, recovery, wiped all caches I can think of. Still happens, just now I was in the middle of installing android revolution hd, and the screen ultradimmed on me so I can't finish the process
Thing is, a few months ago I managed to crack my screen by way of gravity and concrete. I let the samsung brand service centre in Stockholm repair it for me (it is out of warranty) and this issue with the dimming never happened before that. Then again, it didn't happen directly afterwards either... but still. So, I am thinking: either me dropping it caused more damages and this is because of that. Or the service center did a bad install of the new screen. Or, the replacement screen that was installed has a defect in itself. I am leaning a bit towards the third explanation... maybe different batches of screens?
Does anyone have any ideas? If I am to contact the service center and complain about their work I would like to be able to point towards a "known problem"...

Take it back, if it didn't happen before then the new screen is most likely.
It isn't a common problem
Hi everyone !
I'm new here (and not a native english speaker, so apologies in advance for any grammar mistakes)
Before making this thread, I looked for info here, but I'm not sure for what to search.
I'll try to explain my problem here.
I bought a Galaxy SIII from my provider 3 weeks ago and everything looked fine, till last week.
Some times to time, with no apparent reason or cause, while my phone is on sleep mode, on my desk, or in my pocket, playing music, I have the following problem: when I push the on/off button to wake up my phone, my screen is turning on, taking me to the lock screen.
But, my screen brightness is very low, like set to the minimum.
And when I draw my unlocking pattern, screen goes black.
Bottom buttons are lit and my phone seems to be OK, I can feel haptic feedbacks.
But the screen is black.
If I push the on/off button again, screen stays black and bottom buttons are not lit anymore, as a usual Sleep Mode.
If I push on/off again (depending on how much I wait between 2 on/off):
- My phone awakes from Sleep and takes me again to the unlock screen, brightness still very low. And after the unlocking pattern traced, black screen again
- If I didn't wait enought after putting it into sleep mode, in this case, I don't have to redraw the unlocking pattern. I'm back to my home screen...
for 1/4 of a second, stilll with brightness at the minimum. And screen goes black.
And after a serie on onoffonoff, boom, my screen is back to full and normal brightness and everything is OK.
At the beginning, my phone did that once in a while. I thought at the time ti was after pushing the on/off button while using a CPU/RAM hungry app, my phone struggling to recover....
But now, it's totally random.
Depending on .... I don't know what, I have to do the onoffonoff thing 2, 5, 10, 50 times in a row so my phone can recover from is half comatose.
Yesterday, I could not use my phone for half an hour ...
and if someone calls me, I hear the ringtone, but screen stays black.
I can answer the call (but not knowing who's calling) by sliding on the part of the screen where the slider normally is.
Funny thing is about removing the battery. It doesn't solve my problem.
When I do so, my phone boots, I see the "Samsung Galaxy SIII" boot screen, on low brightness (whih is not normal ...)
After that, I normally have another boot screen with my provider's logo and tone. But screen goes black again (but I still here the tone)
Then I realized it started to happen when my phone proposed me a Samsung update.
I tried to reset my phone to factory settings but it didn't work, the update was still here.
For a while I thought my problem was solved, because my phone behaved normally for 3 or 4 hours, without problem.
But it came back.
I found on the internet several "almost-same-problems" without proposed solutions.
Like checking if the proximity sensor was blocked by a protective transparent plastic sheet, or a case.
I tried to to remove mine.
Didn't work.
Some people said it was linked to their phone trying to acquire a wifi network.
My wifi on or off, withiin or without the range of a wifi router didn't work ...
I tried to note things down about what I did, when, how, app launched before the problem appears.
I checked battery info (temp, voltage, etc).
No pattern emerged.
So.
Hs anyone of you enountered the same problem ?
Do you have ideas, solutions I can use ?
Or maybe a voodoo prayer ?
I could sent it back to my provider which will bounce it back to Samsung. But it will take ages (3 to 4 weeks ...) :'(
Thanks in advance !
do a factory reset, go completely stock
if that doesn't help, send it in

That's what I did.
I tried by going into the Parameters menu, and reseting.
I tried by booting my phone with Vol+ / Home / Power buttons to access a console mode and do a wipe data/reset.
The problem is that my phone got an update like one week ago from a 4.?.? to 4.1.2.
And even with a reset, my phone reboot with the 4.1.2 version, which seems to cause this problem.
Or maybe not, but I can't be sure.
As I said, after a factory reset I did yesterday, everything went well for 3 or 4 hours and the problem reappeared.
send it to the service

Dear friends, see this, see in the youtube:
watch?v=ixWozCI8sek
I activated the phone in their own settings of android to show screen touches and strokes that you can see in the video above, and installed YAMTT app to better show the problem.
The Problem on mobile touch in the middle of the screen there is a track that is not recognized touch, but if I press the screen sinking, she returns to work temporarily, and now recognizes the touch - but after a few minutes the problem back and touch is not recognized again.
The screen is perhaps dished up, and when I press down her back to be in contact with the part of the cell that recognizes the touch, but with time the screen should be getting back dished up (this is my guess, not i'm sure).
Detail, not always when I press is running, sometimes I press the screen to the center of the touch again be recognized, but it seems that the phone is registering touches alone.
What would be a solution, and change the screen (it does not mean that changing the screen the problem solved), want to try other alternatives before changing the screen.
Perhaps heating up the screen with hot air, in theory it will expand and become more pliable, and then if I press down the center panel of the phone with something for a while until it cools, in theory the screen would remain indefinitely, and if that is the problem could solve -
Anyone have any thoughts, has been there?
Thanks in advanced!
