Hello guys!
I've just got my repaired HTC Desire 500 from the service center after having yellow line along the screen and usb sync. failure. They said they replaced the entire motherboard and the screen.
Everything worked just fine until I experienced some weird proximity sensor issues. As an HTC user, I use the Gravity Screen app in order to wake the screen through the proximity and gravity sensor to save the power button from prolonged use.
I realized the proximity sensor is not working with the app. And the sensor works 8 out of 10 times when having a phone call, the other 2 times the screen doesn't wake when moving the phone away from my ear.
I tried testing the sensor via the built-in function test, it "most of the time" fails the test. On the other hand, it works okay with phone calls!
The sensor sometimes work, sometimes hang and sometimes never works!
I tried factory reset and wiping cache partition and sensor works okay at the beginning then starts acting weird.
Please help me with your useful feedback because it's truly frustrating!
Lately, my proximity sensor has been giving me trouble - at least, I think it's the proximity sensor. The symptoms:
1) I can't unlock the phone unless there is enough ambient light. Generally not a problem, but a little inconvenient.
2) As soon as I start a call, the screen goes black and will not turn back on no matter what, making it impossible to bring up the dialpad or hang up. I've enabled the "power button to hang up" setting, but it doesn't seem to be doing anything. The only way to end a call is to wait for the other side to hang up or remove the battery. The former is fine if I'm actually talking to a person, but if I get into an auto-attendant tree I'm screwed. It happens regardless of whether I'm holding the phone to my face or not. Flat on a table, same behavior.
The phone is rooted, are there any apps or things I can do to verify that it's the proximity sensor? Is there any way to just disable the proximity sensor in software?
Use the hidden menu (3845#*850#) and go into device test.
There is a proximity sensor test there. As you move your hand near the sensor it wall say near and as you move it away it will give you a light reading.
Thanks - the top always says "Proximity: NEAR". The bottom one says "Light: off" If I wave my hand hear the sensor, it turns blue and give me a reading hovering around 10. Closer to the phone and it's red and gives me a lower reading. Holding my finger on the phone, completely blocking the sensor, gives me the "Light: off" reading again.
I'm not quite sure what to make of that.
I've had similar problems with my international version G3. Both times I have had to take off the back cover, remove the various screws around the top half of the phone, pull off the plastic casing, and then use compressed air to spray out the area around the proximity sensor. After this the phone works fine for a month or so.
Somehow dust seems to be getting into the phone quite easily. I'm wondering if the area around the speaker grill is not fully sealed.
I finally took the time to disassemble my phone and sure enough, the proximity sensor was filthy. A couple seconds with a can of compressed air and things seem to be back to normal.
Thanks!
I have a lg g stylo the sensor is so sensitive .. I wave my hand over my phone and the screen goes black I am trying to figure out how to turn it off ..

Click to expand...
Click to collapse
If it does become a problem there is an exposed module just for diabling prox sensor
Proximity Sensor Issue Solved
Just opened the Mobile yesterday night, and after a little hectic; i had managed to clean the dust from board sensors.
Working Perfect now, like a charm !
I was in the car and my phone slipped out of my pocket and landed on the carpet.
Fingerprint reader stopped working.
Face unlock was still working.
Factory reset the device
Fingerprint reader still not working.
Face unlock still working.
Can anyone offer a suggestion or know what I can do.

Send it back without mentionning the fall? Just say that the fingerprint readed stopped working.
I already tested with a new fingerprint scanner and it still doesnt work. If i attach the fingerprint scanner and turn my phone on, it would start in a bootloop saying "Phone is starting". I had to remove the battery to turn off the phone, unattach the fingerprint scanner, turn on and it works just fine. Well, fine without a fingerprint scanner. So i was wondering if there is something wrong with my board. If any of you have a picture of the board, near the fingerprint scanner area, it would help too.

I had to remove the battery to turn off the phone, un-attach the fingerprint scanner, turn on the phone and it will startup like normal. Well, normal but without a fingerprint scanner.
