I've applied a glass screen protector a few days ago and found that the sensor on this phone is so sensitive that it picking up the reflection from the screen protector, because the sensor is right under the display so it's not possible to have a cutout for it.
You can test a proximity sensor on this phone with *#77692# code, if it stuck in green and vibrates after you press "Proximity On" it means it's thought that the sensor is being obstructed, this will be very annoying when you making a call and screen doesn't turn on automatically after you pull it away from your ears.
What I've done is to reflash stock rom with Odin, checked the "Nand erase all" (This will erase all the /data partition, basically factory reset the phone), when it comes up it has saved the new Proximity sensor baseline reading and everything function correctly again.
I already have this bug. I reboot the phone and the problem gone ! (I make test with an app, more flexible : sensor test)

I got a used S2 Skyrocket, all stock and factory reset. It has a slight crack on the outer glass and the crack seems to run over the proximity sensor.
With this option "Turn on proximity sensor" ENABLED:
- the screen switches off when I take the phone close to my ears. BUT it does not come back on at all when I move it away. I have to like pull the battery out and reboot.
With the option "Turn on proximity sensor" disabled: The screen won't automatically turn off. Is this my only FIX?
I did the self test of the Sensor using the menu I get by dialing *#0*#. When I move my finger over the sensor, the screen turns green and vibrates, but when I move off... there is no change.
So I assume the sensor or the cracked glass is causing this? Question: Can the senor be cleaned by dis-assembling the back side?
I have used my SR's sensor a lot more as part of a Power Button fix. The Smart Screen ON app helps interact with and configure the sensor's screen response, so you might get a clearer view of the malfunction from it.
Nope that app didn't help. I might have to open and clean the sensor...
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!
I have OPO with CM12 nightly firmware.
Problem appeared also in CM11S, CM11 nightly
When in call screen turns black and i can't turn it on.
So if i accidently press to call to wrong person, i cant cancell call.
Found temporary fix: swipe over proximity sensor, then press Power button, and it will turn on in couple seconds.
But it doen't work always.
Hello, fréquent problem when you put a screen protector too near the proximity sensor....
Use Proximity Sensor Finder on play store to test it.
If you see 0.0cm every time remove your protector

Hello,
i see 0.0cm every time, but i have no any screen protector or case, its "as bought"
The "sensor last covered" timer resets every time when i SWYPE the green area (dynamic), not over black something near camera, not when i just put my finger there and thats weird.
The issue is modem. Flash the Alpha modem and it will fix the issue. (I'm too lazy to link but just search and you'll find it)
problem solved with flashing CM11s with full wipe including userdata_64G.img
thanks
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 ..

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 !
Solution on 2nd post.
Hi.
Lately I'm having problems with proximity sensor.
1. During phone calls, after getting phone to my ear, screen turns off and that's fine, but after ending the call screen never wakes up. I have to press the Power button to wake up the screen.
2. After pressing the power button, screen turns off and AOD screen shows up, that's ok, but after putting it to pocket or after covering the proximity sensor with hand and taking it off the AOD screen doesn't show up. It's black screen always. I have to wake up the phone and off for AOD screen to show up.
I was testing the proximity sensor with different testing apps and it is recognizing near proximity but it never recognize that there is nothing near anymore. Ex.: during testing I cover the proximity with hand and it is recognizing it, but when I take my hand off, proximity sensor is still saying there is something near.
Problems started some time ago occasionally but since yesterday it always like that. It started on Android 10. Downgraded to 9 (ver 1.9 from zte de site) and it was ok for 2 weeks like. Yet it started to get stuck for good, even upgrading back to Android 10 (v 2.4) didn't help.
I looked where the sensor is, left side from earpiece and I swear I could see some dust under the glass, but since the phone is waterproof (IP68) how there could be any dust inside? I was shaking the phone to get rid of the dust from the proximity sensor to no avail, sensor is still stuck.
No glass protector applied, no any cover.
What do you guys think? Should I get RMA for it? Or s there anything can be done? Anyone else having these problems?
FIX for proximity sensor getting stuck/not working properly
Found fix by myself.
Proximity sensor in my case got some dust in it or it de-calibrated itself. If proximity sensor is broken on hardware level, probably this solution won't work. Yet, you are free to try it anyway.
If your proximity sensor de-calibrated somehow or got dust on it and it is misbehaving, do the following:
1. Go to Phone app, enter:
Code:
*983*673636#
to enable EMODE (self-testing app), toast info about enabling EMODE will be shown,
2. In the Phone app enter:
Code:
*983*0#
to start the EMODE, menu for various test will be shown,
3. Go to SENSOR TEST
4. Cover the proximity sensor with your hand ? (upper side of the phone ), test will say something like PASS in green color),
5. Swipe to the bottom of the menu, place your phone flat on the table in not so bright environment and hit CALIBRATE.
6. Your sensors are now re-calibrated and proximity sensor will work like new, even if it is dusted.
7. If you want to disable EMODE, go back to Phone app and enter
Code:
*983*2567336#
but refrain from doing so, if you want to run EMODE again in case of any of sensors misbehaving again and wanting to recalibrate later.
That's it, my proximity sensor is working again like new.
Sidenote: if there is dust inside the phone, phone is not so waterproof (IP68) after all. Just be careful with water with it

Hey! I have the same problem with the proximity sensor and even though I did the same that you say, nothing changed.
Do you any other solution?

Sorry to hear that. I have no other solution. Take it to service center.
