Hey Guys. Recently I have started to have an issue with my screen rotation failing to move into landscape and my auto brightness staying dim. It didn't seem to coincide with any software updates which was a bit confusing.
So I cracked on by pulling the back cover and battery and instantly spot a collection of metal filings in a circle directly above the camera sitting on the case. After a clean with an alcoholic wipe, stuck it back together and all was well again.
Just thought I would leave this here just in case anyone else runs into a similar issue :good:

Sometimes the touch screen is not responsive. I need to press screen at various places to get it work again.
Any idea why this is happening?
Due to ROM bug or Hardware issue?
It may sound funny but my TD2 is the same and after few checks I found a way to fix it..... You must look at your display in an angle and you can see that in the center is a spot which is darker than the other display, after this you must suck a little right above the spot and everything is back to normal....
use a duct tape to suck it
this might be caused by extra pressure was placed on the screen. I found out about this when I accidentally slept on my phone for a whole night
Just got myself a transformer today and it seemed great, however right after about 5 minutes the thing goes nuts like someone is swiping or touching the screen. Mostly just one spot on the left side and it will do it whether I'm holding it or it's sitting by itself. Can't seem to find anything posted about this wondering if thats because it's not common or I'm just not looking for the right stuff? Any help would be great, will likely return it tomorrow anyhow but if there's a fix would be nice.
Yeah, I got this as well while playing Angry Birds (F'd up my scores ! ). I don't know if it will work for you, but I just cleaned the screen really well with a cotton ball and alcohol, dried it, then used a microfiber cloth to clean it up (the ones that come with glasses, screen protectors). It worked for me, i think there was some gunk on the screen and was registering as a touch..
Try a factory reset and if it doesn't work take it back for a new one.
Thanks I can't see it being something on screen but will give it a wipe done here in a minute. Also tried the factory reset seemed to help but still getting in same frequency just not as badly. will see if the cleaning doesn't work I'll take it back and replace it.
This is the biggest annoyance that I have as of recent.
I have particularly oily fingerprints which causes smudges constantly.
I love the sensitivity of the TF, but if there is excessive smudging, the residue will register as a screen input - Wish the sensitivity could be adjusted.
Weird things happen when I need to clean the screen... I.E. I will be using a browser and use a single touch to scroll down, but it will zoom in/out instead; the long press menu will show up in a random spot persistently; -or- the screen will be completely unresponsive.
When this happens - I turn of the screen, clean it, turn the screen back on, and I'm good to go (note: sometimes I cannot even see any smudges where I am having issues).
This happens to me FREQUENTLY when i use the tab outside during humid days. I am thinking a screen protector may help, but still havent gotten one to try it out.
I had this same problem before the touch screen completely stopped responding on me.
For mine it only happened after waking it up from sleep mode though. When I turned Timeout to Never the ghost touching stopped.
Well tried as suggested the cleaning of the screen and all that but it still did it so took it back to the store got lucky and they still had one left, and exchanged it. New one hasn't had any issues at all. Thanks all.
I just took mine out of the box for fun (it was packed up for rma) and when i turned it on the touch screen worked. The ghost touching stopped to. But i still have a strip from top to bottom on the right side of the screen that registers two touches . So ill probably still send it in for a replacement.
Hello guys! After a long search on the recent questions in this amazing forum I couldn't find anything similar to my girlfriend problem...
Her Nexus 4 was just fine until the update to 4.3.. After that it started to show a problem during/after calls, the screen turns black completely (even when is not near the face or anything) and its impossible to do anything with the phone after that. Power button doesn't work, and there is only two ways to get the phone working again: the other person hang up the call.. or to hard press the power button until the restart...
I tried already to change for a 4.3 ROM and now I changed it to a 4.2.2 ROM... any idea or suggestions to a possible solution?
Thanks a lot guys!
I too recently had this problem. There was a simple fix after dealing with it a couple of days. My 4yo daughter had been playing with my phone after which I started having the problem. What I found was one of her hairs had become stuck in the bumper and was resting on the screen over the proximity sensor. Once I cleared that, no more problem.
The sensor is on the upper left of the screen.

If You use screen protector and it goes over sensors, than will be the reason of Your problem. Just remove it.
It could be the 4.3 update. I didn't have any such issues until the update and then they began. AndroSensor confirms that no matter what, proximity sensor is at 0.
Any thoughts on what to do short of RMA?

I can assure you its your screen guard that is creating an occlusion for your sensor on top left. Remove it and it will definitely work.

Not sure if I mentioned it earlier (perhaps in another thread) - no screen guard. That wasn't the issue. Finally, I changed the proximity sensor itself, all bueno. No RMA which means avoiding a bunch of hassles (namely new phone, data xfer, etc).

I've noticed that since updating to 4.4 that my sensors are freezing.
I noticed it when I went to use SMS and the screen immediately switched to landscape and would not rotate back when I held the phone upright. I unchecked the auto rotate in the settings and it returned to upright. I also noticed at the same time that the screen was a little dark and was not auto adjusting the brightness.
From the phone I entered *#0*# to get the test page and on opening the sensors they where all stuck solid. Only the proximity would work.
Sensor Hub test shows the STM32 pass.
The only way to fix it is to power off and back on. A re-start does not fix the issue.
I suspect a hardware problem. Anyone else seen this before?

I bought a used V20 with a defective screen. I change it, everything work for fine, but i notice a strange behaviour with the second screen.
The second screen is always on and i can unlock it by only touching the finger print sensor. BUT at night (or in the dark), the second screen turn off and i need to press 2 times on the power button to wake the phone.
The Knock On feature doesn't work too in the dark.
The light sensor seems to work correctly.
I would love to post a video but i can't......
This is an issue or it is normal ??
Thanks for your help !
Sounds like Doze.
I don't find anything related to Doze or "standby" about this screen.
check "daily timeout" on Show when main screen off. Seem u turn this function on at night

Sounds like there is an issue with the proximity sensor (not light sensor).
It's setup to turn the second screen off as well as disable knock on if the phone is in your pocket. Even during daylight hours if you put your finger within an inch of the sensor when the main screen is off, it should trigger it.
It seems your sensor may just be messed up.

There are a few apps on the play store you can try to fix it if you are rooted. You could also try a sensor app to see if the proximity sensor is showing feedback properly although you might need to be rooted for the apps to show the proximity sensor properly (not sure). My note 4 had a hardware test in the service menu not sure how to do it on V20 though.
Same Issue
Edit: Resolved the issue. Please read this post. There is a small rubber gasket-type thing that sits in the hole of the phone's frame where the proximity sensor is positioned. That rubber gasket was not included with my replacement screen. I pulled the rubber piece out of my original, broken screen, and installed it into my replacement screen. I am no longer having issues with the phone in the dark.
I am experiencing the same issue. I have a T-Mobile LG v20 (H918) and I cracked the screen last week. I ordered a replacement LCD assembly and installed it myself. Everything works fine during the day or in a well lit room, but at night, in a dark room, I experience all of the issues you are reporting. I am finding other posts online with our same issue, but as of yet, no resolution.
Even though the second screen is set to always be on, at night, in a dark room, it turns off almost immediately after locking the phone. It is almost as if the phone is in a "deep sleep" or something, because the following also occurs:
Knock On will not wake the phone
Fingerprint sensor will not wake the phone
Even connecting to the phone via AirDroid / AirMirror the phone doesn't wake
Need to press the power button multiple times to wake phone
Providing a light source immediately turns on second screen and resolves all issues
