Hello,
I have a very strange problem with my Xperia Z2. After unlocking the display on the device is blank. You can see the brightness, the touch works, because when I swipe my fingers I can hear android sound but there is no picture. I must do "lock - unlock" pattern 3-4 times, sometimes even more to get the display work properly. I tried to fix it by using software repair but it didnt work, and also
factory reset. Its just so iritating, I cant even lock my phone anymore, I try to keep the display on as much as possible if someone trys to call me so I can answer it. Device is currently running on Existenz ROM but the issue started on the stock so I flashed custom rom but it didn't help. So this is probably a hardware problem and if it is, what could be broken ( is it display, GPU,whatever ) or it could be a software problem ? Any help would be appreciated.
Can you see your lockscreen?

No, no the "lock-unlock pattern" is reffered to simply pressing the unlock button on the phone. There is just blank display and light is on as I mentioned but no picture. After pressing button many times the picture finaly comes and then it's normal. It only happens when phone goes to sleep mode or after I lock it.
If your phone reboots can you see the SONY logo and the boot animation as well?

Nope, there is nothing. Just a sound and LED works, and blank screen. Then again, when the phone finally reboots, pressing lock-unlock button will do the trick. It seems like, when I dont touch the phone longer time, it's harder to get screen on. But when I constantly work with the phone there is no need for that amount of "lock - unlock button move".
mby RIP graph.. try flashtools..

It's probably hardware, now it's just a question of repair cost and is it worth it ?

I think this is due to a faulty LCD screen, but the digitalizer seems fine. So maybe you could consult some local repair shops and prove if my hypothesis is correct. But first of all you should try also flashing another kernel (eg elite kernel) first to see if it is a software issue rather than a hardware issue.

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.
thx, i hope you can help me solving this problem

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
Hello friends.
I just got my Motorolla Atrix 4G and im not abble to unlock it on the unlock screen, the touch just dont works at all there, even the capacitive buttons below not responding. The first day I managed to unlock it somehow after removing the battery, after that the unlock screen was working fine even when I lock the phone so I tough the problem was over and stated to install some basic apps. Like 2 days later the problem was back and now not even removing battery was working, sometimes I get to unlock it but now thats less and less posible. I read that installing an optional unlock screen could do the trick so I installed "Widget Locker" and worked some hours, then the same thing even the Widget Locker unlock screen dosnt respond. Its weird because once I manage to unlock it the touch works perfectly at all so that makes me think its a software/system problem.
Currently I cant unlock it at all, not even removing battery or anything.
The phone its used, I was thinking to bring it to a tech center on here and try root and installing a custom rom?
Thanks in advance for your help guys.
Bump...
Just to add... tried hard reset and didnt worked =/
¿Any sugestion? ¿Should I try an screen change?
Thanks.

Does the problem occur when you move the phone into a vertical position (moving the lock screen)?
Try turning the screen off/on by using the power button (but don't turn the phone off) ... does this help?
When you installed a custom rom did you do a full system wipe? (goto 'mounts/storage' and format pre-install, data, system, osh, cache) before
installing rom.
Hello barry, thanks for the answer.
Yes, the problem occours in both horizontal and vertical positions.
If I press the power button the power off dialog appears on screen and im unable to touch the options, holding the power button dont turn the phone off so im forced to remove the battery to turn it off.
I havent installed a custom rom yet. Thats the next step ill be covering. I toke the phone to a tech center place and asked them to install a custom rom (since I cant persoanlly do the root and flash rom proces) They just told me that it didnt fixed it, but when i turn it on i saw the same Moto Blur interface wich make me think they didnt changed the rom at all...
Sadly when puting a SIM and starting the phone the Motorolla interface screen appeared, but... touch wasnt working there neither wich now starts to make me think it is a hardware problem after all... Im not sure anymore and dont know what to do now
Sorry for the long answer and the bad english.
sounds like your digitizer might need replaced, based off of what I read. just out of curiousity, what android version is it?
Stock Android Gingerbread 2.3 with Moto Blur UI
Digitizer? Not Screen then?
EDIT: Ohh nvm, Digitizer = Touchscreen right?

Yes. Don't confuse the two, the screen has nothing to do with the digitizer, other than one being on top of the other physically.
Hi!
I installed "U20_nAa-14_2.6.29.6-nAa-14" and "MiniCM7-2.2.1-mimmi" on my phone. The mobile network didn't worked, so I tried closing back the bootloader. I made it with "s1tool relock.exe", and it really closed it back. The instructions I followed while doing it, said that I shouldn't start the phone after doing the relocking and disconnecting it from the computer. Accidentally I switched it on, and now it won't turn on. Only the startup vibration and green led flash. If I connect it to the computer it keeps connecting and deconnecting, I don't know how to open up the bootloader again if it's possible at all.
Is it repairable?
Thank you for your help.

Flash THIS with flashtool. The download is about 213 MB, although it may say differently when downloading, just wait till it's finished.
It's original Sony Ericsson Firmware and can be flashed on a device with a locked bootloader. Not sure about the version, although it says 2.1.1.A.0.6, it may be older, but i don't have a U20, so I can't check. It should be possible to upgrade it with Sony Update Service if it's an older version. Good luck.
Thank you!
It worked. Can I ask that too, is there a safest way to solve the no network problem?

Depends on your simlock certificate or how your phone was unlocked from it's original network. There are two or three methods (msm_7227_semc, msm_7227_setool2, and maybe one for omnius too) , just try them and check if you get a signal before you flash any custom firmware. If you don't get a signal, relock it again and try a different method.
Flashtool used to be quite good at figuring out which method worked best, but I don't know if that still supports unlocking 2010 devices. I've got 0.9.13 and there is a BLU (Bootloader UnLock) button.. just try that
I opened it again with msm7227_semc, bacuse the others didn't worked, and installed it again. Now everything is fine, but the home button and the screen lock still not works:/ I think I'll leave it this way, and not risk one more time my network connection.
Thanks for your help.

If it's unlocked and the network is still there you can do whatever you want with it There's no need to lock it ever again so you can experiment with kernels and roms all you want.
What was the matter with the home-button and the screenlock? Do the other buttons work and is the screen ok when you slide out the keyboard?

The other buttons are all fine, and the home looks fine too, just the only way to use it is to turn on the screen with it. Which hasn't got a lock on it, when I push any button, it switches right to the home screen. Turning on lock patterns and others didn't helped. Maybe can I use external applications to substitute the functions?

Hmm, sounds a bit like the ROM doesn't want to go to sleep. Maybe you could reboot into recovery, and wipe data/factory reset, wipe cache and wipe dalvik-cache (from the advanced menu). I'm sure you already did that, but it can't hurt to do it again, and see if that fixes the problem
The phone should enter deep-sleep after about 5 seconds after the screen is turned off, in which case the only way to wake up the screen are the power-button and the home-button. pressing menu or back should keep the phone asleep. If after about 10 or 20 seconds you can still wake up the screen with the back or menu buttons you might want to check if there's an app keeping the phone awake.
Done factory reset and cache wipe already multiple times. Just realized how annoying is the dysfunctional home button, so I tried MiniCM7-2.2.0, MiniCM9-3.0.5 with nAa-11,13,14 and nAa-ics-04. Unfortunatley didn't worked the home button or the screen lock with none of them. At first time, I installed the MiniCM10, but the phone was relatively slow with it and buzzed, so I switched to MiniCM7.
Screen timeout and turnoff delay both set to immediately, but even the camera button can turn on the screen no matter how many time elapses. Can the original MiniCM apps keep it awake? I installed a task killer, but no change.

If it happens on all ROMS, maybe it's your home-button keeping the phone alive, as in that it makes continuous contact. Wouldn't know what to do about that though. Does it happen on stock firmware too?

No, when I restored it with the Sony Update Service everything worked fine on the stock 2.1, and it is still possible to turn on the screen with the home button, but it's other functions are out.
Wow, this time I didn't installed the gapps like it was written in the CM wiki (http://wiki.cyanogenmod.org/w/Install_CM_for_mimmi), both the home button and screen lock works. Why it is written in the "Install CM for mimmi" article if the gapps on the download page is for MiniCM10?
Whatever, shame on me, I should've just take it seriously, and not follow the instructions blindly.:silly:

Hello people.
My amazfit does not respond to the screen when playing.
what can I do?
Same as mine!
Looking for a solution too!
Or a way to control the watch settings by phone. Someone?
Same here, the screen is stuck on selecting left or right hand and the touch screen is not responding. I can pair the watch with my phone and they show everything on the app just the screen is stuck. Please anyone help
Im facing the same after the last update. If i turn my watch on while it's charging, remains normal with all functions and screens. But as soon i disconnect the charger and the screen goes off i'm not able to turn it on again. At least until i reboot it.
If i reboot and keep pressing the screen it works normally, but again as soon as the screen goes off, i'm stucked.
Tried to factory reset, and factory reset without recovering the activities. But nothing changed.

The it looks like a hardware failure... Any chance of water damage?
Touchscreen may behave weirdly if the screen is dirty, specially where it touches the bezel, that would explain why it works when it's connected to the electricity. If it's not the case, then probably some internal component failed...

NO chance of water.
And started to act like that after received the 1.3.8a
Like I've said, the touch still works without connected to the electricity, but i have to turn it on and keeps pressing the touch. Or the screen and the button will be freeze again.
It's very weird actually.

If it's under warranty yet, probably it's better to ask for a replacement. If not, unlock bootloader and do a full wipe (erase all data) and/or re-install stock 1.3.6d.

It's a camera under the screen. The reason the screen flashes is to take a picture of your fingerprint. It's not a hardware or software problem it's normal behavior.
How does your device take a pic of your fingerprint if it can't see it coz it's too dark
