Proximity Sensor Issue! - General Questions and Answers

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!

[Q] Samsung Focus 1.3 Proximity/Light Sensor problem

Does anyone know if there is an issue with the proximity and light sensors in the Samsung Focus v1.3? Neither of them work on mine.
When I go into Diagnosis, the Proximity Sensor test shows XXX where the detection value would be, and the light sensor says "Val: 0000" in red where the ambient light value would be.
This means whenever I make a call, I have to hit the sleep button on the phone to turn the screen off, lest I accidentally press buttons on it with my ear while I'm talking.
All other features and functions of the phone work just fine. I've dropped it once, but the Prox/Light sensor issues started occurring before that.
Any assistance would be appreciated.

Might be a hardware issue i have the same problem, i tried to fix it by installing the factory ROM. No luck. I'm gonna bring it back to rogers to see if i can get it fixed :\

Similar problem
My phone will go to blank screen as soon as I hit "Answer" or for outgoing whet I tap "Call" so I can't put on the speakerphone or hangup. All butons and functions are disabled. I have to remove the battery to reset the phone or wait for the caller to hang up. On calling "VoiceMail" it just goes on and on before hanging up so removing the battery works faster and restarting the computer.
I have tried to adjust the proximity indicator as I read on another forum but it doesn't seem to make any difference. I have to add that this seems intermittent and sometimes it works normal and sometimes not.
Maybe "dropping it" has something to do with it. One forum said customer service wanted him to do a hard reset which I assume is the only way to get rid of the Mango update or any apps installed that may be a contributing factor. If anyone has any ideas let us know.

Blank Screen after finished calling with speaker mode on

Not sure if any of you had this but I notice my phone when placed on speaker mode, after calling my screen goes blank and none of the key function work (all buttons including home, power, etc) and I had to do a battery pull. I assume this may not happen as often but I recently get it a couple times already.
I spoke with the S2 guys and notice this happens to their handheld due to the sensor set. One best way to work around is simply Turn off proximity sensor under Call setting.
This happen when I had a 2.3.6 TGY KK5 stock rom.

yeah buddy same thing happens with my device as well.. bt it doesent always have to be on speaker mode. on normal mode also sometimes my device goes blank..
anyone here help please.....

Several users on our russian forum have reported same problem on different ROMs (2.3.4, 2.3.5 and 2.3.6). Most of them are using phone calls about 60-90 minutes per day.
I never had this issue with my 2.3.5 Germany ROM, but I am using my phone for calls just for 5-10 minutes in a week.
Tip
You don't have to replace battery. Just long press power button (over 10 seconds), and phone should reboot.

I've seen the same problem on my phone, but after I pressed the power button for about 7 seconds and let go, the screen came back and I was able to hang up the call. I've turned off the proximity sensing (settings -> calls -> proximity sensor) and haven't seen the issue since then.

okk i wll give it a try........

my gf is experiencing this issue on her SGR as well. After a call, the phone will become unresponsive and the red spot(light sensor) near the speaker at the top of the phone will be lighted up.
using stock + ardatdat's 1.3A kernel (default settings).
will try the proximity sensor solution and hope the issue goes away.

yes buddy after unchecking the promixity sensor in call option it 0does work... bt still sometime red sensor glows and slows my phone down..... if anything of this kind is experienced then do share..

should be fine once you switch the proximity sensor off as thats what it seems to cause all the prob and the only thing u have to live with is ur screen doesnt go dim when you stick it to ur face while talking

[Q] Proximity sensor troubles, can it be disabled?

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 !

[FIX] Proximity Sensor stuck fix.

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.
