Hi.
I just noticed that a part of my screen, which is upper right corner, is less sensitive than the others. FYI, I just got the phone for a week.
I need to tap harder on that part.
I did a touch sensor test, but I am not sure on how to determine if that exact part of my screen is faulty.
So my questions are;
1. How to know which indicates which through the touch sensor test?
2. Is there any way to fix this myself? Or should I bring my phone to the nearest phone repair shop/the centre?
This problem is really bugging me. Please help.
Thank you

I think my Incredible is finally dying. Top left corner of the screen has zero response to touch input. Affected area is about the size of a dime. Kind of annoying since I use notification power widgets. (CM7.1 Stable)
Anyone else have any experience with their phone's screen partially not working? I'm due for an upgrade in January anyway, but I already told my little sister she could have this phone when i was done with it lol
I saw a case or two in some other forums where the Dinc screen was dying. In particular they had issues with the top half of their screen and precision. If you are running CM7.1, you can take a look at Dev Tools > Pointer Location. It won't help, but it could possibly give you a better idea of how bad off the screen is.
Hey guys...I got an incredible deal on a slight water damaged t989 in otherwise great physical shape, and I really like it. The only issue I'm having with it is when I make a call, the screen goes black (still shows the clock at the top...everything else is black), without ever putting the phone to my face. And after that I can't do anything to get it to come back on.
Is it normal for the screen to still show the clock when the phone is up to your ear? I figured it might be based on how amoled screens work (only producing light locally where it needs it), but wasn't sure.
Also, do you think this is the proximity sensor being faulty? That was my guess...it looks like the part costs $23 and is connected to the front camera. I could also try taking it apart and drying it out better (I already did that with the motherboard and it fixed all the other issues it was having, like the main camera not working)...I'm just a little less inclined to do this since I don't see any guides for disassembling that part of the phone and don't want to accidently damage something.
I guess I'm willing to try opening it up further and airing out the proximity sensor...possibly replacing it...but the important question on my mind is does this phone normally still display the time at the top when you hold it up to your ear?
anybody? It would help me just to know if this phones screen goes completely black when making a call, or if it goes black but still shows the very top with the clock and such when the phones proximity sensor is covered up (ie: held up to the ear)
Hi Guys,
Hoping there's a hardware guru out there who can help Yesterday, I replaced the screen of my stock UK Note 2. All went well until the LOCA glue part which was a nightmare, Anyway, to cut a long story short, the job is done, however, I am now experiencing very strange screen behaviour.
The lower part of the screen (first row of widgets) is unresponsive to touch yet works fine with S Pen, but here is the weird bit, it does respond to touch on the home screens but not in apps ie I can open the camera using my finger but cant activate the shutter button (except with the S Pen). As far as I can tell this happens in all apps. All other aspects work fine and it is purely limited to this bottom strip.
I wasn't happy about the LOCA glue job and I am certain that I had leakage towards the lower half of the phone. What I was wondering was does this behaviour point to a specific hardware part that I can either clean or replace or am I stuffed!
Any help would be much appreciated :fingers-crossed:
Hi, I've searched this forum and the Internet in general about proximity sensor problems but it seems like basically every problem that someone else had was fixed by removing tempered glass/screen protectors/cases/covers. I'm having a proximity sensor issue and I'm not using any screen protector or case.
This has happened twice now. Once when I was listening to visual voicemail, once when I was making a call. The screen goes dark and will not respond to any wake commands. Every now and then it will turn on for half a second when I hit the power button but then turns back off again. The first time when I was listening to visual voicemail, I had to hard restart the phone by holding volume up and power. The second time during the call, I managed to hang up the call in the half second the screen came back on, which ended the problem.
Right after that, I tested the proximity sensor using the SMMI test (calculator .12345+=). The test makes you put your hand near the sensor, then away, then near again. During the test, the phone immediately sensed my hand near the sensor except that my hand was nowhere near the sensor and there was nothing else near the sensor either.
I did a reboot and ran the test again. This time, the test finished correctly. The phone did not detect my hand until I actually put it near the sensor.
I'm running stock everything except I do have root(ZE551ML). I'm leaning towards this being a hardware problem and I've only had the phone for a week so I'm well within my replace period with Amazon. Is there a solution to this I'm missing or should I just replace? I'm a firm believer in troubleshooting first. Plus, setting up the phone the way I like again will be a huge PITA.
Thanks.
I would replace. It does sound like a hardware issue, and your better off getting a replacement instead of a possible pain for the life of your phone.
I get the same, and the flickering screen happened once to me after I I have just put a tempered glas protector on it ... removed it and so far no problems, but who knows.
I think the SMMI test works correctly the first time you start it, and incorrectly the 2nd, 3rd etc ... dont think it is a hardware error ...
Hi all, i have a zen2 with this same problem, i think doing sensor calibration can resolve the issue... but i can´t found how to do, by code, or by app...
Any body know how to do calibration of sensor aproximty?
Thanks in advanced!
Ps. I dont have screen os glass protector...
i don't having tempered glass or any screen protector. my proximity sensor is not working. Even i checked .12345+= but it gives error in proximity sensor. what to do? plz anyone?
same problem
Hi to everyone,
I have the same problem with the proximity sensor.
After a device reboot, the simmi test work correctly, but after some hours the test fails.
Someone know as I can calibrate the sensor ??
Thanks
I just fixed mine, cause I was having that issue for a LONG time now.
I actually just stuck a piece of paper in front of the light sensor part of the sensor window on the screen. It's the right side of the sensor window.
To be more clear, a while back my screen broke, so I ordered a screen online and changed it. Ever since then my prox. sensor didn't work, so I couldn't use the keypad during calls (the screen would go black).
My screen still isn't attached properly, so it's just being held in by the floppy protective case I have on it right now. This allowed me to pull the screen away from the phone a bit and slide a piece of paper behind it right in front of the light sensor. As soon as I blocked the light sensor then the proximity sensor started reading properly.
I got the idea because I was trying to clean the screen, thinking that it might just be dust blocking it or something. That didn't help, so I tried cleaning the sensor, but had the calibration test running at the time, and it instantly worked!
So I kept playing around with it and noticed that every time I blocked the right side of the sensor, it worked, but as soon as I removed the brush I was using to clean, it stopped working.
I stuck a piece of paper in, and BOOM, worked just fine.
People might want to build on this and maybe try sticking a piece of tape over the right part of the sensor. I haven't tried it, and since I finally have it working now, I really don't want to play with it too much and mess it up.
Hope this helps anyone else having this issue.
Hi all,
I am using zenfone 2 laser z550kl. Screen blackout during call and did not come up till the call is cut. I changed only the cover of proximity sensor and phone is working fine. Change the small rubber covering of sensor and it will work.
Hope this will help all if still using asus phone.
I've tried to change the touch feedback setting to long/medium/short but nothing changed.
I attach a video that show what is the problem with the screen/digitizer - when tapping and keep touching (holding) the screen look at the X axis - its not constant as it should be.
The finger hold stable and not moving, but at the screen the dot moving.
I've checked 3 other G4 devices, all of them don't have this issue.
There is no screen protector (neither the one that comes with the device)
Most of the problem is at the top left of the screen, the bottom right is pretty stable.
Its very annoying while use brush/paint, zoom pictures, playing horizontal mode the left side (top of the screen) dosn't work because of this on some games.
Anyone else had this issue?
What is that problem and how do I fix it?
Is it a software / hardware problem?
There is something to make it better? anyone notice this issue?
My g3 was real bad like this it was software changed from kernal to kernal. not really rom to rom. And g4 is horribly over sensative
I have the same problem, for me it's probably hardware and software, because it was better before V20D, but I still had the problem, now it's worst. LG tried to hide this ****ty screen with software. But I repeat it's first an hardware problem... All my left screen is bad and not stable, more than yours.
Try the app "Ghost Touch Tester" and in developer mode activate "Show Touches"
This is very disappointing, reminds me the first android devices at 2010 with the bad touch screen.
Its not that worst, but you expect a smoother and better quality for device on this level.
I guess its a hardware issue, 2 other devices that I've checked dosn't have this issue (of too sensitive touch) even with tempered glass screen protectors.
The left and the top sides are most sensitive then right buttom.
Maybe kernel would fix it, anyway same story with ver. 5 and with the new 6.
Any ideas if there is something to do?
Have a 2 years warranty but I believe they "won't find any problem".

My g4 is pretty bad when trying to type i mispell all kinds of crap and i got the glass on too
My G4 is very difficult to scroll with. It constantly opens links, instead of scrolling. Tried changing the Acessibility settings for response time to slow, and also the pointer speed, but it didn't work. Very frustrating. I almost wonder if someone paid LG to make sure more links get opened. Seems kind of convenient that the end result is you click on almost every single link.
