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...

Is there a way to disable the proximity sensor (preferable completely, at a system level, but the main issue is in-call). I cracked my screen, and due to the crack being directly above the sensor, the screen is sometimes stuck off, sometimes stuck on, and i'd just rather completely disable it.
Thanks in advance!
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 !
My proximity sensor is not turning off the screen when I'm in calls. I think it may (not sure) have something to do with DT2W, which should not be active when the screen is disabled during a call. Anyone else?
Edit: after spending a while on a call tonight playing with it, I think the proximity sensor is causing the problem, it turns off the screen when it's right up against my ear but move it slightly back to the edge of my ear where it's like a half an inch to my head from the proximity sensor, the screen turns back on. It should be sensing objects a few inches away, 2 at a minimum, not a half an inch.
My proximity sensor only activates on androsensor when my finger is about an eighth of an inch from my phone, a tiny, tiny gap. Can anyone on 5.1.6 or higher confirm whether the proximity sensor activates at an inappropriate distance or not? Like I said androsensor was the app I used if you need one
Very generally said, I am having the same problem! During calls my display always turns on randomly and I accidently press buttons involuntarily during calls. Is there any solution or fix for it?
Hi all,
I just got a 2018 Galaxy A7 this week.
I can't get the Always On Screen to function correctly.
When the proximity sensor at the top of the screen is covered, the screen will fade all the way down, but not shut off completely.
If I leave the phone face down on a table, I can see the screen dimly reflected off the surface if I turn the lights off.
From the manual: "If the sensor at the top of the device is covered for a certain period, the Always On Display will turn off". So it should turn off if face down, in a pocket, etc?
I tried setting "Block Accidental Touches" but this makes no difference. Same for a factory reset in case something I installed was holding the screen on.
Am I missing a required setting?
With thanks
Also: I checked with the built-in tests (dial *#0*#). The proximity and light sensors seem to work ok, so this appears to be a software or setting issue? Or a mistake in the manual?
I confirm that the aod will automatically turn off if I put my phone into my pocket. But I afraid of the burn out of my display. The aod seem to stay the same position in a very long period and there is no option to set up the period for the movement of the aod. Maybe I will turn this funtion off.
Thanks for checking. I'll contact Samsung about this.
I don't know if you need to worry about burn in, the clock and other information seems to move around often enough. Even the home button moves slightly to avoid issues. They've used these screens with these anti-burn in measures for a while and there hasn't been a large number of complaints.
Yeah, A7 has this function and I worry about the burn in of its screen but it do not have LED notification and because of that I must use aod. But the A6, my wife's phone, do not have aod and LED notification. Why Samsung did not support LED indicator for A series? It so annoying.
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.
