How to get display working? - Android Q&A, Help & Troubleshooting

Hello!
I have changed the display for LG E975 phone, but when I turn on the phone the phone screen remains black with some blink of white screen. When I put back old display it has stopped to give the picture. I can't see the picture and I have not activated LG On-Screen Phone. The phone is able to start, when Android loads I can hear when the new mail is received. This is happening with both new and old display. How to troubleshoot / solve this?
Thanks!

[Q] Black screen when accessing Camera-> Pixellated screen instead of Nokia logo

Hi All,
I had an issue with my phone giving a black screen when accessing the camera application till Saturday.
I tried the volume down+ power option, but to no avail. Reset the phone after backing up the data.
Still camera not working, it was blurry sometimes and sometimes the bottom icons worked to switch to the front which was working fine.
I was using the phone as it is till today as I was not able to give it to service center today and wanted to give it tomorrow but sometime back, the phone went into a pixellated screen and the phone wont give any video.
whenever I restart the phone, instead of the nokia logo, it gives a completely pixellated screen.
Not sure what to do. Looks like only option remaining is to take it to a Nokia Care center here in hyderabad.
Any suggestions???

Sounds like a hardware issue. Not something that could be fixed with a wipe or anything. Send it back, that is what a warranty is for. See if they can give you a loan phone while they have yours. Most providers will do that if you have a warranty.

[Q] LG G2 D802 problem when making or answering a call

Hi guys.I have a problem with my LG G2 D802.When I answer a call or make a call,the screen goes blank and the touch doesn't work anymore.I can't do anything else on the phone.The conversation is normal and anything else seems to be ok.Please help! Thank you.
If I answer a call,the screen goes blank,I can speak normally:After the call even the other person finishes the conversation,I still can't do anything on the phone,because the screen stays blank.If I have another call this will awake the screen and it will work normally,I mean,I can take the call,answer and speak on the phone but with the screen blank again. and so on.To have the phone back to normal,I have to reboot it by switching the phone off and on again. Very strange.This happened after I unlocked the phone ,probably because I left the SIM card in ?!!! Any possible advice/solution? I tried soft and hard/factory reset with no results.

I actually had this same issue. my g2 is rooted, but running the stock rom. it has a screen protector but nothing else that would impede the sensors.
I found that this issue never took place in well lit areas. but if at night sitting i a poorly lit room I would go to swipe the scree it would unlock for a second or two and then lock back up. in talking with a friend. I found that the g2 has in set so in the proximity of a pocket or something dark the screen dims back so as to not allow you to mistakenly hit ay button ( i.e. butt dial) i figured my proximity sensor near the ear piece was dirty and causing much less light then there actually was. at the time there wast a firmware update ( which I have now gotten) and was desperately seeking help.
I finally got the firmware update VS98012B and it seems to have solved the issue I ( and you) was having. I would see what version you are running now and then update to the aforementioned and see if that solves your problem.
PM me and let me know what road you decide to travel and if for some reason it doesn't help you we shall figure it out.
Blank Screen
I am having sort of the same issue. But mine is wether in a well lit room or dark room it doesn't matter.
I noticed that it usually happens when i receive a call, after the conversation when i hang up it does not go back to the home screen. all i get is a blank screen. the only way i can get it to generate the home screen again is by pulling down the status bar and going into the general settings and clicking home button again.
during this blank screen i can still see the status bar, and when i bring down the status bar i can see the nav buttons but they are unresponsive.
I also noticed this takes place sometimes after closing an app (noticed on netflix)
I am rooted on stock rom and TWRP recovery. Phone Model [LS-980 Sprint]
I immediately rooted so dont know if issue was there before root.
SOMEONE PLEASE HELP.

I decided to open the phone and check the proximity sensor.I unplugged the proximity sensor ribbon and guess what:IT WORKS.without the functions of the proximity sensor and LED.But at least,I have the keypad and the screen on during a conversation.I have even the knock-knock function.Probably,I will use it like that until a kit-kat update will be available.Thanks for your answer.
VS980 Black Screen
I have a customer phone that I replaced the LCD and Digitizer on. The new screen works fine but...now when a SIM Card is in the phone and I dial out a thin horizontal line appears in the middle of the screen and then the screen goes black.
If I remove the SIM card and place a call, the phone gives me the standard "Emergency Calls Only" and goes back to the dial pad.
The SIM Card is not activated but it is recognized by the phone.
Has anyone else had this issue? I tried a factory restore with no luck.

Hi,
I have the same issue , my screen turns black when calling or receiving calls , i m not really good with my hands... so do you know other solutions to disable the proximity sensor ?
thanks
Same issue here - LG G2 screen turn off and goes blank during conversations
I have exactly the same issue - LG G2 D802 screen turn off and goes blank during conversations.
Thanks to @Bam9 and @EtherBoo , who suggested to clear the proximity sensor from the outside and squeeze the top left corner of the phone, I tried to clean it and put some stress on it - and it worked!
Another issue which I also have and is also caused by the proximity sensor is that the screen stays on and the touch buttons in the dialer aren't responsive - which means we can't switch to speaker, add a call, mute, etc... However, the main touch / navigation button (home, back and menu buttons in the bottom of the screen) are responsive, in addition to the status bar.
(This issue was already reported by @athorax here)
In both of these situations the only quick way to end a call is to pull down the status and notifications bar and hang up from there.
I have a glass screen protector (which don't block the proximity sensor), and I am rooted and using CyanogenMod 11 ROM.
I used ioroot to root and AutoRec, which comes with TWRP 2.7.0.0, to install CyanogenMod ROM.
However, going back to stock ROM (in my case, LG G2 D802, it's D80220C) won't help since the issue still exists.
What I'm sure is that it was pretty much okay in the beginning, and the situation became worse and worse - occurring randomly, until it arrived to a situation in which I can't use the phone properly during conversation.
Now that I discovered that I can put some stress on the proximity sensor it seems that I have a hardware rather than a software issue.

So for you it was a software issue?
Is your sensor working until today with no issues?

I'm also rooted and with TWRP.
Did it happened before you rooted?
Did you used ioroot to root andAutoRec to have TWRP?
You see, I'm really trying to find the similarities between us all in order to solve this issue...

We already have KitKat based firmware update. For me it's D80220C.
For you it might be already D80220D. Use this link to check your version, and replace the IMEI in the end of it with your IMEI.

When you place the call you do hear that the call is made?
If so - then you have exactly the same issue.
What is your model, what ROM are you using, and did you root your phone?
I have LG G2, unable to make call. The signal strength is fine. I have tried reinserting the sim. but i am able to receive calls. when i make a call the dialup screen come up and call ended automatically. Any Help

[HELP] Dim LCD Problem

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.

LG G2 developing major malfuction

Hello all, I am currently researching some new phone as my Lg G2 is failing. I thought I would explain the issue though incase its something that could be fixed. The issue started the other day when my phone kept activating in my pocket even with screen lock on. When I try to use my phone the screen would randomly change to a clock face with a small lock symbol in the bottom right of the clock . This clock would be on the top of the screen and the screen would only respond to touch inside the clock image. It would not unlock when swiping. Also while this clock is on my screen if I received a incomming call the clock would be replace with the normal accept or decline screen while shrunk in this small box the clock occupied. It would let me swipe accept call and talk.
I could not google this issue, anyone seen this before?
Thanks.
Wanted to add, I also reset phone back to factory settings and it didnt fix it.

Second screen always on problem

Hello. I've got this weird problem on my LG V10 (H901). Second screen show nothing when main screen is off, even settings for second screen are all set. It's ok when main screen is on. I have tested proximity and light sensor and it's working ok, I do factory reset, upgraded with KDZ vie LGUP but problem persist. Even stranger is that shortcuts (for example bluetoot, flashlight etc..) are working if you touch second screen area, but there is no light on screen. Does anyone know how to fix this issue?
