i'm having a frustrating issue after replacing the screen on my sister's Moto G.
nothing is wrong with the new screen, everything is in good working condition there. however, neither the proximity sensor, ambient light sensor or accelerometer are working anymore. i don't understand why because as far as i can tell those components are attached to the motherboard and shouldn't have been affected by the replacement of the screen module. also, the front facing camera is not working either but that's my fault. when i put the phone back together i accidentally broke off that tiny lever you have to flip up to remove the camera in the first place. i guess the camera can't plug back in properly without it. so then i wonder if the missing front camera could be causing the other component issues?? that doesn't sound right to me but i thought i should mention it anyway. i have no idea how i'm going to fix the broken lever without replacing the whole motherboard...the screen alone was already $60. ugh
so my question would be does anyone know why these parts aren't working anymore, and how could i fix them? none of them destroy the phone's core functionality but i would like to get them working. i don't own an Android phone and i'm not really familiar with the OS, would a factory reset maybe get things working?

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.
I have a photon Q LTE
Something is terribly going wrong with this one , first the front camera stopped working , when i click , nothing happens , the button is greyed out i thought it was software so i factory reset , still nothing rear camera is working fine though.
then when i opened the keyboard the touch screen becomes disables , i can't do anything on via touch screen when keyboard is opened.
then now touch screen completely stopped working
i think hearing songs in bathroom was not a good idea , moisture got in , i believe , i tried many ways to dry it out but eveyrthing is becoming worse.
i am out of warranty and sprint charges 50 dollars and not guarantee of any recovery
any help would be highly appreciate.
All of the things you describe indicate some sort of hardware issue - with water certainly being suspect if you think it got into the device.
I'm not sure what we can suggest exactly, other than the obvious - throw it in rice and hope, although most of the components are sealed, so if you are experiencing issues it is probably too late.
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 have a nexus 5 ( marshmallow). I have (stupidly) dropped it twice and the screen is quite damaged. When I receive or make a call the screen goes black. I can't access the touchpad, speaker etc. Very annoying. I am replacing the screen now but the question I have is whether I also need to replace the proximity sensor.
Is it related to my issue? Or will replacing the screen fix everything? The person that is replacing the screen is charging an extra £10 for the sensor if he can do both together. He says if it turns out I need the sensor afterwards it will cost £40 so I would rather do it in one go if I need to.
I have installed the Proximity Screen Off app but it makes no difference.
Thanks

There is a known issue with the proximity sensor not working correctly in Marshmallow for the Nexus 5 it is especially noticable when making or receiving calls.
You can see the complaints from other Nexus 5 users here https://productforums.google.com/forum/#!topic/nexus/oqh-V37hgDM
This doesn't mean that your proximity sensor isn't damaged but the issue doesn't occur on Lollipop. If you can revert to Lollipop temporarily to test before you make your decision would be a better way to test if there is a problem with the sensor.
Is it even possible to replace just the proximity sensor on Nexus 5? I can't find any info about it
