Have the Rogers HTC One X....its rooted and bootloader unlocked using the HTCDev method. The only problem i have is with the Proximity Sensor!!
During calls, unless i COMPLETELY cover the sensor, as in the phone is pressed against my face/ear...the phone will stay on!!
So now its seems like it only has two settings: Screen ON when nothing is there. Screen OFF when i COMPLETELY block it instead how it used to b where i cud come close and it wud turn off. This is really annoying, because unless im pressing the phone really hard against my face, itll b on. N even then sometimes, i have to take the phone away, and then put it back against my face for the screen to go off..
USING Z DEVICE TEST: the proximity sensor range = 9cm, resolution +/- 9cm. Shows only two distance readings: either 9cm or 0cm. And again, i have to completely block the sensor and the reading goes to 0cm.
I wiped dalvik cache, tried different ROMS, dont know what the problem is....PLEASE HELP!!!!
anyone..? No one?!?
Mine works fine and the tool says the same - +/- 9cm. The only thing that changes while viewing that menu is the green bar that pops up to 100% when the proximity sensor senses something close. The depth of about three decks of cards stacked on each other is how close my hand can get without tripping the sensor. If you are having the same issue across ROMS, you most likely have a hardware issue. I'd flash it back to a stock ROM just to be sure (might want to stay away from the newest if you are flashing an RUU for now).

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.
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
Hi all,
When I'm using my month old Nexus 5 it will just randomly kick me back to the lock screen, sometimes I can just unlock it and keep on trucking but sometimes it will just immediately lock again or it will work for a couple of seconds and then re-lock. Once its in this state even a reboot doesn't always help and about the only thing I can do is get into recovery mode and re-flash it again. I used the Sensor Box app and have noticed that the light sensor is always reading zero, and I'm not sure if this is part of the issue?
This was happening on the PA Alpha, Stock 5.0.1 and since I was still having the issue I flashed back to 4.4.
The weird thing is that my phone had been fine for the 3 weeks or so I had it before hand. I flashed lollipop on it less than an hour after I took it out of the box and it had been running smoothly up until yesterday.
So a few questions:
Is there anything I can try to fix ir?
Can I use debugging to see what is causing the screen to lock?
Is this likely to be a hardware issue?
If it is, is there anything I will need to do to make sure I keep my warranty?
Any help is very much appreciated.
Bump with some other information:
I don't think its the light sensor, I tried using the phone in a pitch black room last night and the same thing was constantly happening, there was something else odd happening though.
From the restore of 4.4 I was on the "Select language" screen, whilst I could swipe and roll the various language options up and down the moment I presses "Next" the phone locked, if I left the phone on this screen eventually the screen would automatically lock and then it would keep locking itself constantly again.
Also, just for total clarification by "lock" I meaning "return to lock screen" not freeze up and become unresponsive.
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 !
Good morning, i have a Note 20 Ultra exynos version and when i test the proximity sensor i have no response. It's possible ??
Thanks
yes, it is implemented differently. it works fine with apps that support it
What do you mean by "test"?
When you're on a phone call it should turn off the screen if you cover the sensor.
No if i cover the entire note the screen is always on.

Using the mic not in speaker phone mode?
If so it sounds like it's not working... phone screen should go dark when it's against your face on a call.
Try clearing the system cache on the boot menu, this may fix it.
Try it in safe mode for the off chance a 3rd party is the cause.
When i try with a call it seems to work but after two or three attempts the screen remain on also if i close the cover..

Not sure but that sounds like software.
You said cover as in a wallet case?
There may be a setting for that but if so I have no clue.
Doesn't sound like a normal operation unless it's a Samsung case and it's suppose to do that.
Don't think there's even a visible specific system apk for it. You could try clearing the Android Systems cache maybe data too but that may cause more trouble with lost settings... and end up worse off for the trouble.
On the note 10+ a small faint blinking circle is visible about a quarter inch to the right of the front cam cut out when the proximity sensor is active. Not flashing, not active.
If that helps you any...
Note: if it's active during a call and I trip it 2-4 times with a second or two spacing, the screen will remain off until I turn it back on.
This is normal operation.
Ok thaks a lot for your explanation..
I'm having the same issue which started today. Every time I put the phone up to my ear to place/ receive calls the proximity sensor isn't working and I'm pressing all random buttons accidentally with my cheek. I've turned my phone on and off to try to get it to work and no dice. It was working fine before today so I'm not sure what happened. I didn't drop my phone or anything. A google search showed this has been a problem since the S10 when Samsung embedded the sensor under the screen and dropped to turn on/ off this feature under call settings.
Advice anyone?
Try in safe mode. If it works there it's most likely a 3rd party app.
Was -anything- updated or just installed?
Did you change any settings?
Try a "hard" reboot and clear System Cache in boot menu.
Clear Android Systems cache.

Is a hard reboot restoring everything to factory settings? If not can you provide me the steps I need to complete to get there and If I need to back up everything and how to go about doing that? I'm a novice who's learning everyday so I appreciate your patience

No! Not a hard reset!
Hard reboot simulates pulling the battery...
I think I got it to work again. Hard reboot I guess according to google is pressing the “Volume down” and Power / lock key for 10 to 20 seconds bypassing the options shown on the screen until the phone turns off by itself. I then pressed the volume up key and the power/ lock key until the android recovery menu came up on the screen. I then chose "wipe cache Partition" and rebooted the phone after that.
It seems to be working again and hope this helps anyone who starts encountering this problem like I did.

Clearing the System cache can fix a lot of Android voodoo gremlins. I clear mine regularly or if the Android is acting erratically.
Hello
I am the owner of a Note 20 Ultra starting today.
I previously had a Note 10 Plus, where the proximity sensor showed as a blinking white light near the front camera.
At Note 20 Ultra there is no sign of its presence, no blinking light. Is this normal? Can the real owners check and confirm?
I also checked with secret codes:
Using *#0*# and selecting Sensor opens a menu where I cant find any proximity sensor
Using *#77692# opens a window with proximity and light sensor; for proximity sensor I turn on and wave my hand over the front camera area, it vibrates and turns display green each time, but after several attempts (7-8) it stops working.
So, is this normal? It has a new algorithm or type of sensor?
Please check and confirm.
Thank you

Its possible that there is no sensor, I have not done any research on this but it is possible to use front camera as proximity sensor. It would mean that the function would activate when you are on call and not on loudspeaker, it should not be tough to implement.
It has a discreet proximity sensor...

I have seen this article but it is useful only to locate the proximity sensor. But regarding how it is actually working, there are no details.
I was expecting something similar with Note 10 Plus but there was no blinking led/pixel to be found when having a call.
And honestly, I am not very impressed with its functioning. When using phone on left ear especially it skips activating many times.
Also, during a call (normally not on speaker), when I cover the top of the phone with my hand, the screen does not go black instantly (I must keep it covered about 3-4 seconds) but if I puck up the phone to my ear it seems to activate, which makes me think it has an algorythm that includes other sensors like gyroscope. Or maybe my proximity sensor is faulty... but as I said, if I test it with proper code, it seems to be present and work.... Which makes me thing it is a software problem.
So, I come back to my previous details and kindly ask other Note 20 Ultra users to replicate similar behaviour.
Thank you
My note 20 Ultra sensor works fine if the speaker is off. Turn the speaker on and the proximity sensor is disabled.
Try using this code in dialer.
*#77692# and then turn proximity sensor on and put hand over top part if it lits up green then it's working as it should. But if it remains white and nothing happens then there is an issue with sensor.
