Samsung A8 - Proximity sensor not working - Samsung Galaxy A8 (2018) Questions & Answers

Hi, I have just purchased A8 and updated its software to:
Android 7.1.1
Samsung Experience 8.5
Basband version A530FXXU2ARC9
I have noticed that proximity sensor does not work, which means that during calls the screen stays on and I always accidentally press something with my ear. I have started to lock the screen with power button but this is not the way as it should be.
Does someone else have the same problem?
I have tried to reboot it, factory default it, I have even tried to install Proximity Sensor Reset/Repair app.
When dialed *#0*# I can see the proximity sensor there but it's always in 0.0 value.
Any suggestions?

I would return it for repairs. Of course you can always try a factory reset.

It's faulty.

[Q] samsung focus 7 - reset proximity sensor

how do i calibrate proximity sensor from the diagnostic menu. for samsung focus.
Basically my phones screen goes blank when i make a call and I have put my thumb on the proximity sensor to "wake" it up. I was reading somewhere that this could be "fixed" by resetting proximity sensor through diagnoistic menu. but i couldnt figure out how
Actually, the same thing happens on my Optimus 7. When I make a call, the screen goes blank, unless I have Bluetooth or headset attached. It takes a few seconds, or as you described a hand wave over the proximity sensor to bring back the screen.
Dunno if you got this answered but...
From the Diagnosis keypad, type *#0*#
Then tap toe Proximity button.
Issue with proximity sensor in Samsung focus sgh i917
I have the same problem. My LED screen broke recently and replaced it.
It looks like after the screen replacement, the phone's proximity sensor is always in detected mode [in the diag]. So when ever a phone is made or answered the LED screen goes blank disabling all functionality till the other person disconnects.
I ran the diag but it doesn't give me an option to calibrate the sensor. I tried to install the latest diag tool too but same results. There is only one button, "EXIT".
The diagnostic app version is .0628
OS version is 7.10.7720.68
Please help.

I know exactly how to fix your problem. I had the same issue! I replaced my Samsung Focus's LED screen, and exactly the same problem as yours! I tried everything here, but didn't work. I finally found the solution. When you take the old screen off your phone, there is 3M tape (black) between the two little sensor. That rips off with the old screen when you take it off. The one sensor shoots infra-red, which should not be detected by the sensor right next to it. so, when that black glue is not there, it senses it and shots the screen off. So, what i did, i took a tinny piece of sticky black rubber from that stuff that you fill the whole in your car tire when it's punctured, the tire fix kit, and put it between the two sensors, below the screen of course, and to my amazement, it now works!
try it and let me know if it worked! Make sure though that you don't cover the sensors with it. I'm sure it will work. hope you haven't spend more money to fix it and that I'm not too late to give you the solution.
Later!

[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.

[Q] How to calibrate/ fix the proximity sensor of MTK 6589 [Konka V981 rebrand]

Hi, I've been having some problems with my proximity sensor lately.. I have only noticed it during my first call last January in which my girlfriend called me and upon finish I checked my screen to see that it's still black, tried to power on/ power off, but only the capacitive buttons would light not the screen.
I have used Phone tester to check my proximity sensor and tried it.. It says Waiting... then I put my finger on top of it, it says Near.. After I remove my finger, it's still stuck on Near.. So clearly , my proximity sensor is operational but is at fault or bugged.
Bottom line is, does anyone know how to calibrate or fix my issue? I have a Konka V981 phone, rebranded here in my country to what's now called Cosmos X2.. With an MTK 6589 chipset.
Thank you in advance to whoever could help me solve my problem. Hoping to find the solution from the professionals in this forum and/ or site.

try flashing a custom rom
Oh I forgot to mention that I've flashed multiple ROMs onto my unit but the problem still persists... I've tried about 6 roms and all of them have the same output, my proximity sensor is still at fault.. From Waiting... to Near... and never going back to Far.. It should be, or the normal should be near upon putting my finger or something in front of it, to far, removing the object, or my finger from it..
I tried a Note 3 rom, whereas I noticed that the proximity sensor wasnt needed for call sessions, whereas I could just power off power on when Im on call so my face wont randomly tap the screen and make a mess.. But I don't want to keep the Note 3 rom, so I flashed back to our modified Stockrom Android 4.2.2.. And then the problem came back..
If only someone could help me calibrate or at most turn it off.. Id be grateful.. But Id be more grateful if we could just calibrate it rather than turning it off

Proximity Sensor Issue!

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!

Proximity sensor

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.
