[Q] Brightness adjustment doesn't work. Screen won´t turn on again. - Epic 4G Q&A, Help & Troubleshooting

Hello guys, I hope some one can help me out here.
Yesterday, after I woke up I noticed my phone has turned off, I turned it on again with no problem, minutes later I tried to check something on it but the screen doesn't turned on, the backlight from the keyboard and the 4 button under the screen still works, I can press any button and it sounds like phone still works, even with the camera button I hear the shutter like the phone take the photo, the system is on while the screen is still off. The only way to see the screen now, is removing the battery and leave the screen on all the time, I notice then that the brightness adjust doesn't work and it got stuck in the last one used (about 40%).
I was at the moment with CM9. I tried with stock rom using Odin, also again with CM9, and CM10.2. Changed kernel in the last two but the problem is still there.
UPDATE: I just tried CM7 and brightness control works, but still has the problem.
Do you have any ideas for this? Thanks in advance.
P.D. Sorry for the bad English.

[Q] Screen automatically on every minute

Hi everyone,
I've been using Android Revolution HD 3.1 since it is out, and I manually formatted everything what was needed before installing the rom. Kernel is the one supplied with the rom and it is the recommended radio (12.35d.60.140fP_26.06.03.24_M2)
everything works fine, except that the screen turns on every minute by itself and turns of like 5 seconds later. I've checked and nothing is pressing the power button. the problem is, is that it is very regular.
anyone any idea how to solve this?

You ve current widget installed? If yes, try removing that and see if the problem goes away
thanks for your answer, I finally found the culprit, it wasn't currentwidget, it was the taptap app. as soon as I turned off the sensor, the screen wasn't turning on anymore. never guessed it would be taptap as when I connect it to power, nothing happens. only on battery.
thanks anyway

[Q] Turns on by itself after pressing the power button?

Hi All,
I would like to describe something which I'm not sure if it is just me or a bug. There have been a few occasions where I have pressed the power button to put the phone to sleep and after a second, the screen turns back on again. I've tried to replicate it by maybe the way I have pressed it and it could have a residual effect on the button, thinking I want to turn it on again but I've not been successful. It just happens on and off.
Other than that, I love my HTC One X. Just like to find out if others do encounter this. Thanks! =)

Thought it was just me, looks like it's a bug.
Same here, doesn't always happen
Same here, but happened only 3 or 4. Also i was unable to reproduce it on purpose.
Great, at least I'm not alone and it is not due to my way of pressing the power button. Hope HTC fixes this bug in the next update. Thanks all! =)
Me too!!!
same here
Mine does this too, also mines rooted with custom rom. I can replicate it if a press the screen lock button a few times it just shuts off, no shut down or any warning about what's its done. Do we know if this is a hardware or software fault as I guess my warranty is void after rooting.
Same here. I hope somebody can provide a solution.
I've had this before on my sensation but not on my HOX.. running cm10

Hmmm
Yup same ting happen to me I really thought it was me alone dat had dat problem and again I have a custom rom install, was even thinking or going back to original art ruu hoping it would solve the problem , the thing is its my back up fone incase of emergency I'm using my galaxy note 3 and now and them I keep hear a beep when I look the fone is on lol I just feel the one x has too many bugs
yeah.. same thing happened to me after i change my recovery to philz and rom to aosb.
Whenever i turn off my phone and charging, it will boot into recovery. after a while it will boot up itself as usual.
Never happened to me in stock recovery/rom... Not sure what is the cause

Hi Thant,
Thanks for the info. But my battery doesn't even full or almost full. Even when my battery is only 8% left it will boot up automatically.
i wish they have option to turn the feature off..

[Q] Weird problem with screen-HTC One X

Hello,
I was looking through the XDA, but haven't found anything similar, so I hope somebody could have an idea what could it be.
First of all, phone is HTC One X-32GB International version.
Few days ago, I noticed that after some idle time, my HOX touch screen becomes unresponsive.At first, I didn't pay too much attention, because everything was fine after restar by power button, but problem continued to repeat.I thought it could be because of the heavy use, so I started to disable app by app but nothing changed.I restarted it several times after that and noticed that if I try side buttons, they show volume is going up and down when I press them.Also a big screen clock is normally working, so my next guess was that maybe a factory reset would solve the problem,but it didn't.
So what i shappenintg?
When I surf the net,or dialling numbers,or whatever else, everything works fine to the moment I stop touching it and leave it idle for a while.After few minutes, screen is unresponsive, doesn't matter if I put screenlock on or of.I can't even answer the call when it rings.Everything looks just as it should look,but is unresponsive.Except side buttons.Then again I have to restart it with long press power button.If I don't touch the screen after phone restarts, after minute or two it goes to unresponsive state again.
I hope somebody has idea what could or what should I do.
Thanks in advance
*update
Sometimes helps if I press power button...
*update 2
Now it's not helping any more if I press power button, seems that power button is not reacting at all sometimes, only if I hold him long enough to restart it.
In fact, now even restart is not helping.
I'm sorry, what ROM do you have? And do you have sweep2wake function on? 'cause I also have had problems with touch, when s2w was on, but I am not sure, what was the ROM that time...

It's a stock ROM-And sweep2wake is not on.
Have no idea what else to try.I tried to unlock bootloader,put CWM in because you can control it with buttons, made a backup of everything to USB, format everything, put everything back, but problem is still here.Now I also noticed that it has a delay when push power button for example when I press it screen goes off immidiately,but when I press it again, sometimes it takes 20 seconds just to turn screen on again.And of course, it still not reacting.
Now my last hope is that a ROM became corrupted somehow,so I will try to delete everything, and put some other ROM in.
Since, I am a noob, there will be a lot reading for me .
Everything wiped, unboxed ROM on, and a problem still persists.
Newest discovery:if I twist upper right corner a little bit, everything works fine.

Open up your phone and check the connector for the digitizer is properly connected, even remove it and blow into the connector to make sure there's no dust causing problems.
You can test the screen response before putting the back cover on again, its pretty easy and there are videos on YouTube showing how to remove the back, good luck.

I found some time to open it yesterday evening, and connectors are as they should be.I also tried to remove them, and blow them out, but no use.
Thank you anyway.
I think I will sell it like this for parts.

Phone working but screen black

Hello everyone,
I have since the first time an LG G3 (D855) that I root and that works very well.
Recently I bought a new one from a friend for my girlfriend.
He never root it, he reset it and sent it to me by mail.
At the reception, I turn on the phone and there, I have the LED lights, sound start but nothing on the screen.
It reacts when I put the finger on the screen so the touch sensor works.
I try a restart and battery removal but nothing better.
The screen has no shock but I told myself that perhaps during the trip he took a bad cut.
I hope it's just a miswired table, so I dismounted to check, but still nothing.
ThenI try something, I disconnect my phone too and I swapped motherboards.
And then the screen with my card in it work.
While my screen with the motherboards of the phone I just bought stay blank.
So the screen is not broken, perhaps it was a install problem.
So I use LG Flash Tool to reinstall the original rom (following a tutorial )
Everything goes well and ends without worries.
But that didnt change anything, the screen is still black.
Do you have an idea ?
Thank you in advance for your assistance and sorry for my bad english
I just realized that if I strongly illuminates the screen I can see that it works.
It' like brightness was at zero.
It's not a screen problem because when I plug it to the other motherboard brightness is ok.
Someone had this issue?
Same problem here
So I'm having the same problem at the moment, but this is the 2nd time that this has happened to me. Last time. I fixed it by changing charger. It worked for like 2-3 month and then I switched again and the problem came back. I suggest you try a few charges. It took around a week before it got fixed.
Hope it'll work for you.
BTW it was a Nokia charger
Black screen G2 after some seconds even during boot...

Exactly the same problem on my LG G2.
It often go to black screen, but it's not totally OFF. Touch work, and the screen the same, i noticed using a torch that the brightness when to something like zero, but if i increase the level, it stay dark. Only press power button sometimes come back, but few second later... Dark screen again.
It happens everywhere during boot, in home, in lockscreen, in TWRP.
I tried:
- Change rom
- Flash stock firmware...
- Totally switched off for 2 months
- Detach and reattach the screen
- Test proximity sensor in hidden menu
Nothing worked.
If anyone has an idea...

Black Screen

When I was using this phone the screen suddenly turned black. No powering off or anything, the phone was nearly fully charged anyway. Nothing seems to be working anymore. I tried turning it back on but it's completely unresponsive. It won't even charge anymore. I was wondering if there was any solutions to this and if other people where having this problem or did my phone just brick itself
Are you able to get to the bootloader? by pressing volume + and power at the same time. It may be worth trying to flash stock also. I am no expert its just what I would try.

Of course I did. But at no avail. Today, I found out, that the new screen is partially working. I can see very dark picture, it means, I have no back light. Tried to set it up from engineers mode, but no luck.
So the new screen is on, but without back light, and the phone heats pretty much in the top area.

If so. Try to pull down the statusbar and swipe a bit under the statusbar line, in the top of the screen from left to right, with some luck you will tap the brightness switcher

I can connect to the phone through Vysor, and when I change the brightness level there, there is no change at all. The Phone does not react to any settings change at all.
Tried eragon rom, but still no change....

Better hope you still have your garantie, because theres legit no way to restore it. You just have to send it back for it to get fixed. This happened to me once and yesterday twice. sadly I am to dissapointed from this. I am never buying an Elephone again ! PS bro it isnt worth sending this hell of a **** peace back. It costs and the blackscreen thing is gonna happen again in 6-8 months. SO go out there and buy yourself a real phone not this bull****. I have to do the same rn.

Just happened to me with my 3 year old phone. Left overnight with enough charge. Pressed the side button and nothing - held it down to restart and then complete blank.
Repalced the battery about 1 month ago with one from AliExpress for £5.
So using the kit provided with the battery or a watchmakers screwdriver - undo the 12 tiny screws and remove the white surround and then the inner back with the phone's number on it. Next disconnect the battery socket but be careful as it is tiny - use a torch and magnifier if vision not good. Remove the sim card. Wait 10 minutes - did this with the blue light flashing - it stopped finally on disconnection.
Put it all back together and hey presto fully working phone
