so i got a rooted at&t lg g2 and almost everything works perfect but i noticed my proximity sensor doesnt work as every time i make a call the screen stays on. so i went to the market and downloaded a couple of apps that test the sensors and oddly enough they all say that there is no sensors active or on to turn them on and try again WTH any ideas how to fix this could it be a software issue? i did like 3 or 4 hard resets and still nothing any help greatly appreciated thanks

Hi,
I have a problem whit my Samsung Galaxy Note. When ever I have rooted my phone, the touch screen randomly stops working. It seems to happen whenever I come near the proximity sensor during the time when I make a call. I know that it is used to dim/lock the screen during the call but it seems that the touchscreen system chrashes at that point and stays in that locked mode. After a reboot everything is fine untill it randomly happens again.
When such thing happens, the stylus is working but the finger touch is not reckognized anymore. The strange thing is that when I unroot my phone everything seems to work fine.
And that is a bummer because I cannot sent it for replacement because everything seems to work fine when my phone is stock/unrooted.
The phone is brand new, got it last saturday.
Is there any one who has heard of this problem?
Thanks in advance,
Jeffrey

try wiping dalvik cache after rooting sometimes helps small bugs like tht
First time poster, though been a regular lurker.
It seems I have a slightly dodgy proximity sensor. Have checked with one of the proximity sensor apps and while the sensor detects if I have my hand over it, it is very unreliable when I take my hand off. It can take from anywhere from 1 to 30 seconds or sometimes never.
While ive been through other threads where people have a completely failed sensor, does anyone have this intermittent problem. Also is this a hardware or software issue.
Im currently htc-dev unlocked running Pacman v15.0.
Out there is a tool for recalibrating the sensor, but you would need to be S-OFF I think and it's done with a service tool (a special PG88DIAG.nbh)
Let me know if you are willing to try it, but it is VERY dangerous if you do the wrong things.
I had the exact problem from the very beginning. Got a phone and the very next day had a screen protector applied. For a few days proximity sensor created problems. The screen would go black when the call started, but until the call did not end, there was no way to bring the screen back. So, I used an app just like yourself to check and saw the same thing happening. Ultimately read extensively and realised it was due to screen protector. Took a scissor and cut off the protector above the sensor. A few months later when I had a new protector (of a different company) applied the same problem reappeared, so I had to cut it off from the top. Except that this time around I was sort of expecting it. I hope this help! :fingers-crossed:
I had the same problem and it continued no matter whether i remove the protector or cut the portion....im unable to most awesome ROM's.......only n sense 4.0 im able to re turn on the screen using power button.if there a way to completely disable this turn off during calls irrespective of the ROM its highly appreciated......
Looking forward for the solution

An update to my situation.. I ordered a new proximity sensor on e-bay and have replaced the same on my phone now. While I was at it, I cleaned up the window as it was pretty grimy and could have been the source of trouble. Also cleaned up the contacts with Isopropyl alcohol. End result.. Im still having the same problem!!
Im pretty sure now that its not a hardware problem and has to do with the calibration. What I have noticed that the sensor works fine in bright sunlight but not when there is less light around. Also am not using a screen guard!
Would it be possible to guide me to the right tools to recalibrate please?
Sorry, I haven't done this myself, but I'll search a bit how it's done by HTC.
They are using a special holding station where the devices are calibrated.
Hi,
I recently replaced my cracked screen and all went well, expect that now the proximity sensor doesn't seem to work 90% of the time. When I make a phone call the screen goes off and it won't come back on when I move the phone away from my face. Either party has to hang up in order to get the screen back on. I've opened the phone up and double checked the ribbons and cables, everything seems ok.
The sensor itself appears to be fine, it's connected direct to the motherboard by the looks of things. I've wiped the phone completely just in case it was software related but that hasn't helped. Has anyone got any advice on how to fix this? I guess I could try to source a broken One S and replace the motherboard, but I don't want to spend too much on getting it working.
Any troubleshooting advice most welcome..
Cheers...
Mines been doing this since the htc repair centre had it,but its got a lot worse recently, proper random though it will work say 10% of the time.
I can't help with the sensor but I set the power button to end calls, its in the accessibility tab in settings, does make it impossible to use the key pad for options on phone calls though.
My screen goes black when I am in a phone call and it does not turn on unless I hold the power button or something like that. I have already went to the proximity settings to test that it is working.
Any ideas?
Firmware version? Seems to be a bug in last firmwares. Also had this issue some time. Now it seems to be gone.

.In the process of backing up my phone atm to try a factory reset. I'm on latest T-mobile version though.
How did you fix yours?
Bump. Anyone? Is there a fix or is my sensor faulty? Because if it is I can still send it back in for a replacement. Sometimes it will work fine, and sometimes it won't.
I've got similar problem. When sensor is activated, it's keeping activated even if nothing is in front of sensor, so I have to wait for other side to end a call.. any suggestions?
EDIT: problem solved-> I just cleaned the glass on proximity sensor, maybe some dust was there

I also have a problem with phone's proximity sensor. With me, it shows some signs of work right after i boot up the phone. In service menu (*#*#7378423#*#*) -> Proximity switch starts with On value and then goes Off, On, Off, On.. a cycle of at least one minute. The interesting thing is when i cover the sensor it stays On, which means it detects its working. I suppose the sensor is faulty, as I tried several suggested methods to resolve this issue: pressing firmly on top of the sensor, factory resets, reinstalling the software with Sony's PC software kit, some applications from Google market, etc. None of them helped.
As I bought my phone 2nd hand, I see the upper speaker is pressed on its left side a little bit, as if the phone was dropped exactly on this spot at the speaker (which I find is almost impossible, as the front panel is perfect without scratches or anything) or somehow it was pushed with some sharp object. I explained this as it might have a link with the proximity sensor issue, or it may not be connected to it, not sure.
I really don't know if this is a right place or not but i want to mention it here, this started when i accidentally leave my phone at heavy rain. It stopped working for 2-3 days and when it started i found total loss over touch, i replaced it and then it was working fine except... its proximity and other sensors are not working and it take almost 5 min to turn on, i though it may be hardware issue, but than after some days it reboots normally and everything was working again except proximity, it remains this good for a while even doesn't get affected by reboots but then again everything was gone, after that day it happens for few times, i didn't recognise what made it go smoothly and than what made it worst again, help me with thar pls.... I also see color stripes for a while clicking on cancel in download mod....i'd installed stock rom more than 2 times and now on CM14.1 help me.....

Greetings and welcome to assist. If returning to stock doesn't work then it must be a hardware issue I'm afraid and there is little we can do to help with that. Really hope you manage to fix it
Good luck
