My lg v20 H910 has a black vertical line that divides the screen into two parts, at first it was almost invisible but now it's persistent and won't go away i'm rooted but i tried reverting back to stock and installed resurrection remix.. every time this line comes back it stays longer than the time before it.

Are you using any overlay app? Maybe screen filter of some sort?

Wow so even after flashing back to stock you're still getting black screen? I've seen the black screen a few times with miui but not everytime. I was hoping it would be fixed with the final v5.
thats weird. the first time a flashed Miui I had that same problem. I just reflashed the same rom and the problem went away. I have never carried the black screen through multiple roms.
Even I flash back to the stock rom by RSD the black screen can't fixed. I already replaced the camera module but not fixed.
Do you use autokiller memory optimizer? I got black screens when I set it above strict. If you do maybe youd want to lower those settings.
I didn't install the auto killer, But even i flash back to 2.1 stock rom without any tweak apps,it still can't fixed the black screen
Hmm, same issue in several ROMs, sounds like an hardware error.
I have found the following in Loyat Forum:
(http://forum.lowyat.net/topic/1667176)
Help! My camera shutter suddenly closed up and can't open anymore. Is this normal or my phone is screwed?
This is a known issue for xt720. Not all of them though but quite a number have experienced it already where the shutter just completely shut. There's nothing much can be done other than sending it back for warranty... OR you can try this trick. Get a magnet and put its South field close to the shutter. Apparently it will open up. Not sure how true is this but yea.... better than dismantle the whole phone just to find out you really screw the phone up for good...​
Maybe this could help...

[Q] Transparent locked screen beneath actual display?

Hi guys, I am having a bit of an issue with my Samsung Infuse. I recently purchase this refurbished phone and it is unlocked from AT&T. Every thing seems to work fine except for the fact that there is constantly a second display underneath the actual display. What I mean by this is that the default locked AT&T screen is always showing, but it is transparent so it overlaps with whatever else is supposed to be displayed on my screen. I assume it is the locked at&t screen because on the bottom it says "phone locked" has a clock and on the top it has an at&t logo.
I tried hard-resetting the phone to factory setting too. I also tried to disabled the lock screen, but it was separate from the transparent at&t lock screen.
Any ideas?
bump.
So I tried a few things. Namely, I tried to install a custom rom to "overwrite" whatever interface the phone previously had. I installed cm9 but I am still having this problem. Any ideas?

idk..is it a transparent background wallpaper?
is there a loose video connection to the screen?
screen shot or video may help show what you mean
It could also be screen burn-in, but, I've never heard of the "phone lock". Mines has the loading symbol and status bar burned into my screen
Sent from my SGH-I997 using xda app-developers app
I will try to get a high quality photo if I can. Unfortunately, my phone is my main camera.
And I looked up what screen burn-in is. It actually looks pretty similar.

Thanks. I will try to see if there are any solution to screen burn in

Black lines on screen

Hello
Today I had a very bad accident with my LG G2 smatphone.
I had an official CM 11 on board. Wanted to update it to CM 12, found this one: http://forum.xda-developers.com/att-g2/development/5-0-2-cyanogenmod-12-t3037040
Downloaded, flashed, everything was fine. Then I installed SuperSU from the Play store. Next, opened the app and tried to install the components it needed. It failed. The app recommended to reboot. After rebooting, the screen was all white with dark corners, I was able to see the interface through the white layer, it looked like this one I found on Google: http://i.stack.imgur.com/gGYktm.jpg
After turning off and on the screen, the colors came back to normal, BUT there are now exactly five one pixel width black lines through the entire length of the screen.
Teriffied, I rebooted quickly to recovery (the lines are there aswell) and installed back CM 11 from the backup with senseless hope. It didn't help.
The phone was connected through the USB cable to my laptop all the time.
Couldn't find any fix to the problem, please help me, the phone is new and without warranty. (the guy that sold me it didn't say it was the ATT D800 one, I live in Europe so no warranty here, I guess.)

Its an incorrect firmware case. Don't worry. Simply restore it using the LG Flash tool and you should be fine. And remember, always go to CM12 site for most recent firmware files.

You you search, you'll find it is a common problem. It is likely related to overheating, and it is a permanent. Fortunately it is not so critical and you can live with it

Android Oreo Developer Preview Image Released!

This preview of the Oreo build is updated with the March 2018 security patches. It is Android Oreo, version 8.1. If you want to use this, keep in mind that this is a development preview! It is not the final release. There are also a few things to note about using it.
It requires you to be bootloader unlocked (unlocking wipes your phone)
This update will wipe your phone even if you're already unlocked
You will not get any OTAs while on this build
VoLTE and WiFi Calling might not work
No CTS, so Android Pay/Pokemon Go may not work
May be some undocumented bugs
If you're fine with all of that, then the download link can be found on Razer's developer page about the update.
If you want to go back to the stock Nougat images, just follow the instructions here.
If anyone does this can they show us some videos

Look up a video of Oreo on a Pixel. It looks exactly the same.
No default white theme like normal Oreo same default theme as nougat.
Screen now has a colour option which can be set to show more vibrant colours.
Double tap to sleep (only on lockscreen)
Speakers seem louder than before.
And all the normal Oreo stuff
Also Pokémon go does work.

Color options and more power for the speakers are both great news. Much excited.
I'm tinkering with GSIs and I've realised you can go into Download Mode by tapping the Power button several times as soon as the Razer logo pops up (before the orange 'tampered' message appears).
In case that helps someone ^

I wonder if there's a way of doing that with maybe the volume buttons to go directly into recovery as well ?

It did the same thing to me when I flashed stock nougat to fix boot loop. Remove and reinstall the Sim card. That worked for me.
Anyone having Bluetooth mic issues on this preview?
Just got a new BT headset with a built in mic and it ain't working. Just thought I'd check in here before returning it.
I went back to Nougat but did anyone else notice the screen colours go between vibrant and normal all the time? noticed it on the lockscreen, Keyboard and quick toggles but it only seemed to happen with colourful stuff. Default Razer wallpaper, Coloured keyboard and theme applied etc
Yes @Roxas598 I did notice the colors change from vibrant to normal a lot. And I've been watching Netflix on it lately as well and have been watching the second season of a series of unfortunate events and the whole show has been looking darker than it should, making it hard to watch even with brightness all the way up.

I already reported the issue but wanted to make sure it wasn't just me. Thanks!
My Fitbit is not being recognised at all, and my bluetooth mic on my new headphones doesn't work. So it looks like there are some issues with Bluetooth which I'll revert to stock to resolve. Not bad so far, but obviously being close to stock means it doesn't feel much different to 7.1, certainly not enough that you get that excited buzz we once got back when Android revisions were massively different.

How did you do this? I'd like to know since I'd like to use Netflix and Google Pay.

Question Bug with proximity sensor

Hi guys,
It often happens to me that screens shuts off when I try to click on top tier of screen, it's really annoying especially with full screen apps.
I recently put on screen protector film but I don't know if it's due to this.
Anyone has this problem ?
Many thanks.
Are you rooted and using [MOD][Xposed+Magisk][Pre-Release] AOSP Mods - System modifications for AOSP-based Android 12+'s option to double-tap the status bar to sleep? If so, it might be related to that setting. I was trying to reproduce a different bug, playing a full-screen landscape YouTube video and I found almost every time I tried to make the status bar appear and then drag it down, I accidentally shut the screen off.
Luckily for me, I rarely try to do something like that while in a full-screen landscape app, so I'm keeping that setting on.
If you're not rooted or not using that Magisk Module, then ignore this.
I'm not.
It happens even whith WhatsApp when I select a message in a conversation and try to click on delete icon located in top screen, screen shuts off.
Where is the promixity sensor ?

I'm not really sure. I just unlocked my P7P and ran my finger across the status bar, back and forth and I never found it.

Meanwhile, the cutout for the proximity sensor has been slightly tweaked again and is more to the right of the front-facing camera than last year’s Pro phone.

I have the same problem. TMobile Visual Voicemail has its delete button just below and to the right of the front camera and the screen turns off before I can delete the playing voicemail. I have to go back to the full list of voicemails and delete from there.
