Help...!!! Display Issue...!!! Screen dark but runs in background! - Xperia Z2 Q&A, Help & Troubleshooting

Since last week my display acting weirdly. Currently on eXistenZ Premium | 6.0.0 | 30/11 LB
After few seconds of use screen goes black (but back light still on) but runs in background & when screen off manually (by double tapping or power button) then on manually (by double tapping or power button) lockscreen appears normal & then can unlock & work normally for some times till the same thing happened. Some times even boot screen face the same problem but after turning screen off & on allow the phone to work for few mins till the problem starts again.
I've tried stock ROMs, custom ROMs, in Unlocked & Locked bootloaders but the problem exists. I wondered if it is a heat related problem as I can work for a longer period if I keep phone switch off for some time.
Please help to solve this...!!! I'm really depressed.! :crying::crying::crying:

Hi,
I have been using Ex Roms for a while now and not experienced this. ( Currently using 6.0 prem )
I will recommend i clean/fresh install. I.E
Flash latest .264 FTF ... with wipe selected.
Flash Adroplus Kernel in Fastboot & Flash Rom.
My current method ... trust this helps.

[Q] XWKI8 Screen not timing out

Hi,
I recently updated to the XWKI8 stock firmware and now the screen fails to time out I have tried setting the time out to 15s/30s/1 min but the screen never switches off.
Is this a know issue? Is there any work around? I am getting fantastic battery time gains by upgrading from 2.3.3 but all is lost the moment the screen gets turned on due to an incoming message (when the phone is in my pocket) and then never gets turned off)

1) Tried normal reboot since flash?
2) Updated via Kies? So maybe you try to reflash it but then you have to do it via Odin (Kies just see that it's the actually one)

Please try the following - if not already done:
1. Wipe cache partition in recovery mode (Volume UP + Home + Power).
2. If you have CWM then also clear Dalvik cache (for Java VM).
If that does not help either, you may have to make a hard reset (*2767*3855#).
As this will wipe internal SD card, be sure to have everything in a backup elsewhere.
EDIT:
Here is another guess to try before.
There are two different places where you can set the screen off time.
The one you found is (I am sure) in Menu => Settings => Display => Screen timeout.
The other one is in Menu => Locations and Security => Timeout.
Maybe there is an other value set on your phone.
Try to change this setting before wiping everything.
Good luck !
Resolved!
A combination of the above two suggestions resolved the problem. Tried setting and unsetting security options and rebooting. It seems to be working now.
Thanks guys!

Back to STOCK :)

So last aug. 5 i hijack my sisters phone with CM7 with no problem encountered in less than 30mins..hahahaha..1st problem encountered: the lock screen (the pattern) it seems that i dont know how to make it work i think something is interfering with the lock screen pattern (idk what it is) then today the pattern i made last aug 5 isnt working now (i am 100% sure that is the pattern i made ) 2nd: before i put the CM7 my sister installed instagram on the stock ROM and there's no problem with it BUT with i port it to CM7 *BOOM* device is incompatible O.O same version same file size same phone any suggestion what when wrong? my priority is how to reset the pattern if the lockscreen wont show in the screen every time i press the (power button) is animates the off screen but when i press it again the LOCKSCREEN is not there O.O
HELP )
If you want to reset the lockscreen, just go to recovery and flash the CM7 ROM again and do a data-wipe. You'll loose everything on the phone memory (apps).

[Q] Several major bugs with AOKP (Neo MT15i)

Hi. This is first time I rooted and changed something to my phone's core system. I bootloaded through Flashtool and got in the newest kernel, ROM and GApps from this thread: http://forum.xda-developers.com/showthread.php?t=1613017 and my baseband is 77 (http://www.mediafire.com/?1oyztnqww22bgek). Things looked fine and my system was working as it should. But soon I was starting to see these bugs:
Screen moving from left to right and back at recovery menu on vol up/down press. Not a big bug though, still possible to work with the menu and read the text.
No lockscreen. Tried all the lockscreen options at settings, but power button still just turns the screen on and off. I can only see the lockscreen right after I reboot my phone and before I enter the PIN, the wheel works as I've set it but then I can't get into the lockscreen anymore.
Strange menu button functionality. Firstly, when I was in the home screen and pressed the menu button, a menu with system settings popped up. Now nothing happens, for both HW and SW buttons. Since the time it worked I was just messing with settings but I'm sure I didn't disable anything like that.
Browser and Google Play not working, Play says RH-01 error, browser just crashes. GMail works.
Tilt not working properly. It did after the fresh install, but now it works only for menus, not for homescreen like it did before. I've tried running a widesecreen-only game but it's being displayed in normal, portrait mode- with errors. Enabling/disabling the tilting didn't help.
And I believe that there are more bugs I didn't mention. I did everything as told in this article http://www.theandroidsoul.com/aokp-xperia-neo/, just with getting the newest links instead of the ones provided. I installed the Hallon version of AOKP and I was running GB 2.3.4 before, if that helps. And like I said- I am doing it for the first time so I am quite new to these things, so firstly sorry if I didn't mention anything important and please describe the steps about how to fix it a little bit more detailed. Thanks!
Hi..
That ROM is legend sometimes ago,and dont have problems like you said.
The step I did was like this :
1. Flash full firmware ICS(.ftf file)with flashtool.
2.Flash kernel
3. Flash ROM
4. Flash Gapps
5. Flash Add-on if any
Enjoy
Sent from my Xperia Neo V
MT15i_4.1.B.0.587_Global.ftf ICS firmware and hallon kernel flashed through Flashtool, then rebooted into system. Then in revocery I wiped cache, dalvik and reseted to factory, installed the newest AOKP ROM, installed GApps, booted into system. My screen is still moving from sides as the screen refreshes in recovery. But after booting, still the same issues persist...
Inside the old recovery,screen dancing is known issue,try Flash other kernel,no harm changing kernel.
Can you provide,Aokp ROM version and kernel you have..
Sent from my Xperia Neo V
AOKP Hallon JB Milestone 1
I tried the CM10.1 and my recovery menu fixed but the bugs weren't fixed, so then I flashed the CM10 and my recovery menu changed again, now with black background and again, fixed animations. But then my device bricked so I flashed again the MT15i_4.1.B.0.587_kernel.ftf.
Couldn't you just send me links to a working combination of kernel-firmware with AOKP? The requirements says I need baseband 72/77, do you have any links or tips for these? I've tried several combinations but just none really worked, now I am on stock laggy JB 4.0.4 and I have no idea what to try now...

[Q] [Help] i9100 won't show lock screen or power menu

Hello guys, firstly, I wanna say this issue I encountered is pretty anodyne, but anyway, I wanna solve it cause it's annoying.
So, I was using a S2 with CM10.2 installed and I wanted to replace it with the [ZERO]BUG ROM v5.0+Premium Suite to, basically, improve its battery life and other minor issues. So I executed an "unclean" install, cause I directly entered CWM and installed the ROM, without installing the stock 4.1.2 via Odin and then again root the phone and install CWM. So it went ok apparently, but everytime I try to lock the screen, it surely locks, but no lock screen appears when I turn it on. Plus, the phone shuts down when I keep the power button pressed 2 seconds, and no power menu appears on the screen before that.
I thought it was a bad "coordination" between the two ROMs, because of the unclean installation, so I installed stock 4.1.2 via Odin to keep in that ROM cause it's pretty good, but still no lock screen or power menu.
So I wanna know how to solve this, cause I'd like to sell the phone and it has to be perfect for that. I don't care to stay in stock, go for CM or another custom CM/stock-based, I just wanna solve it.
So thanks in advance to all of you who are trying to help me.

Facing strange Black Screen Problem even after booting of the Phone successfully

Hi,
I'm facing a strange Black Screen Problem even after booting of the phone successfully every time. I can see the lock screen every time for like 2-3 seconds then suddenly entering to black screen automatically if I try to unlock or don't attempt to do so. The phone is able to ring if I try to make a call from other no. but won't able to pick up because there is no option to answer or decline the call. If I hit the power button all power menu buttons are coming like to reboot, power off , airplane mode etc but some how I'm not able to access the phone from inside.
Please note that last time when the phone was running fine I saw one error like android.system.mui has stopped working and everything was crashing so I had to reboot my phone and ultimately landed into this issue. Also my internal storage was like 600-500 MB free that time.
I'm on miui 9 official for Redmi Note 4 ( 32GB version SD 625).
I'm a new member of XDA and I haven't read all the rules yet, so I apologies if I do any mistake please correct me if I'm wrong as this my first post in XDA. I respect all the community guidelines.
Please provide the working solution for this.
A few quick questions as follows
- Do I have to install TWRP recovery for the same to clear cache which i think it may resolve the issue just removing the cache?
- I'm not sure about Miui recovery 3.0 clear data option to clear cache as i don't really want to erase my all important documents, photos, videos, notes in my phone.
- How can I recover my data if I had to reset my device ?
Please guide me for the above issue.
I really appreciate all your concerns.
Thanks & Regards,
Gaurav Kumar
I have exactly same problem, please help with solution.

Are you able to boot into the recovery and use it? Or does the recovery shows the black screen also?
hey I`ve just got the same problem in Redmi note 4, did u find any solution?...
so far what i did till now is, flash Red Wolf Recovery, wipe, DALVICK, CACHE and DATA (not the internal storage where is your info), the wipe is like a factory reset, is the only solution I`ve found so far.
any ideas?

Do you have a unlocked bootloader? If you don't then possibly resetting device from recovery is the only thing.
Does this issue already solved? I also have the same issue but I don't know how to fix it. Please help me
HI
I have the same problem, I tried using the fastboot (power+volume down) and nothing happened, I tried the recovery mode (power + volume up) and I got three options, (reboot, wipe data, connect with mi assistant) the first would reboot the phone to the same problem, the second one I don't want to wipe all data or reset the phone as I want to retrieve the data on it, I tried the third and downloaded the mi pc suite, but the phone doesn't show on my pc, I receive the no device detected even after connecting my phone with USB
I have the same issue on my Mi Max 2!!!
And the developer mode isn't possible to enable, because of this black screen!
Please help!

I updated my Mi Note 4 system software yesterday to MIUI 9.6 (me thinks), but it is having booting issues. I struggled 2 hours last night to get it started but in the morning I noticed that the fingertip sensor isnt working. I cleared cache, added new finger print, still the problem persisted and then I read on the forum to power off and restart the phone. I clicked on power off and since then my phone is not rebooting. The screen in black, I can hear phone calls, msg notifications. I have tried pressing the power button for 40 seconds (as per the MI Support Tech's advice), followed by using the fastboot (power+volume down) and nothing happened, I tried the recovery mode (power + volume up). Still nothing is showing. The Mi logo and android restart option isn't showing only. The phone is black. I can see navigation light and the blue light blinking on the top left when msg/notification comes. I haven't taken a back up since many many months. I don't want to lose my data. Please help.

Why don't you throw your data in a PC or a memory card? Also guys if im not mistaken you can not rollback from MIUI 10 to an earlier version if you update via the OTA right?Or else your phoned will be bricked am i right? Someone confirm this cause its risky.
Solution for mi black screen.
Hello friends,
I think the issue in sensors, because when i bump my mobile on my hand the screen wake up suddenly but some time screen in hang position but when i try it one or more time its working normally .
Same issue
Hi, I recently updated to the 9.6.2.0 in my Mi note 4 and after reboot it started to go off and on (only the backlight (touch layer worked)). I rebooted several times and get it going. after few minutes went black again and after reboot the fingerprint sensor stopped working (HW diagnostics saying error if you try to test it) and then the battery status started act weir. If i plug phone to charger, no matter how many % i ve got it charge only 1% (after hour or so)and if i unplug it lose 5% in 5 seconds and stays there for amount of time till the battery reach the same percentage as the indication is sayin.
TBH pretty weird and pretty annoying.
And yes it is probably sensor ( or a driver? ) because turning phone up-side down or covering the proximity sensor osometimes help.
I dont want to wipe my phone until it is necessary.
Is it because of update?
Thank you
