This is a heads up for anybody else that starts having problems with their phone not waking up once the screen goes blank after taking a call:
I put a skinomi kit on my defy, and it works great EXCEPT it fools the proximity sensor thereby rendering the phone unusable! Once in a call and the screen goes blank, there's no way to wake it back up. Strangely, even the power button doesn't do anything.
I used a proximity test program from the market to verify the problem, and sure enough, as soon as I pulled the screen protector off, everything started working fine again! And no, there was not dust/dirt/smudges on the screen protector - must be just the density of the material...
i've to disagree with you ,,,i installed the skinomi kit on my phone maybe 3 months ago,and none of what you say happened even once,your skinomi must by yellow as hell,that's why its missing around with your proximity.just my opinion.
nopr, no yellow.just put it on a couple days ago-very clear.
does yours have a cutout for the proximity sensor? maybe just a hardware variation...
Nope,my kit is full body coverage, with no cuts,so either your proximity sensor is faulty or you got a skinomi knockoff.

I can verify that the proximity sensor has issues with skinomi .
Had the same problem ,and solved it with cutting out the part of the screen protector that was covering the sensor .
Since then ,no problem.
Just received a replacement from Skinomi. Same problem - no cut out and the proximity sensor does not work. Manually cut out the area with some scissors, and all is well (but looks bad).
Might be a hardware difference between different variations, but there's definitely a problem for certain models!
I've just received a new Skinomi skin. The area around proximity sensor is cut, so there should be no problem with it anymore. I have not installed it yet though.
Installed it. Works fine. Definitely looks better than bestskinsever I had on my iPhone. Bestskins had an orange peel, Skinomi is smooth. Installation is the same.

Bought this for my wife's phone. Pretty unhappy with it. First off there was some glue in the middle of the glass when i was about to apply it to the phone. So i already had to wipe this off otherwise there would have been a glaring mark on the screen. I used some glass cleaner and had to scrub pretty hard with a microfiber cloth to get it off. Once I dealt with that the screen itself fit pretty well.
But we shortly after we noticed that there was a major problem with the proximity sensor. You could see a faint red glow always on and the phone would not detect how far our heads were from the screen. Using a third party app the sensor would always read 0.0 cm. Once I removed it, everything was operating fine again. Lastly, we also noticed that the touch sensitivity was decreased while using the screen which was extremely annoying. Some screen swipes or taps just didn't register with the phone.
Overall, I would not recommend this product.
Currently, I'm still trying to email them about replacing it with a normal skin.
Hi Guys,
Newbie here, wonderful forum and lots of tech stuff, kudos to every one who have contributed.:good:
Facing couple of issues with my NOKIA X, request your help pls!
Issue: Screen goes blank during a call, when using the phone without headset, & doesnt come back on, untill the call is disconnected by the caller at the other end.During this period, when the screen goes blank, it leaves me with no access to the menu, dialpad, etc and the call disconnect button doesnt end the call as well.
1) Turned off proxmity sensor in the "Phone-Settings" menu, it works properly.ie the screen stays "on" during the call and no issues with disconnecting the call, accessing the other dialpad options etc.
2)Also Turned on/off Automatically adjust screen brightness , observed that issue is intermittent.
Any leads would be helpful.Not sure about sensor calibration and tweaks
thanks

the screen supposedly to turn off during calls when it detect something near the proximity sensor ie your face when attending calls, this is to preserve power, and it should've come back on again when u bring it far from your face. this is default bahaviour on all smartphones nowadays.
but when it doesn't come back on again after u bring it far from your face after making calls, then thats a problem.
u use screen protector? a thick one and it covering the proximity sensor perhaps? from my experience thick screen protector that covering the sensor can interfere with its sensitivity.
the sensor is on the right side of the nokia logo infront of the phone. look closely and u could see it.

Thanks for your reply!.
Yes recently i got a matt finish screen protector on.,let me try taking it off and then observe if the issue pops up..Yes its a little frsutrating when the screen doesnt come back on once its moved away from the face & will have to wait till the caller disconnects the line from their end

Thank you mdfzhi, i took off the screen guard (yeah it looked unusually thick :silly and it seems to work at the moment, will monitor and see if the issue pops up!:good:
thanks again!!
search for screen protector that doesn't cover the proximity sensor, or if u cant find one that doesn't, cut yourself a hole in place of the sensor.
i'm using a thick anti fingerprint screen protector myself but its not covering the proximity sensor.

Someone please CONFORM THIS BUG!
Especially someone running stock! ( I had issues with all stock versions)
@SilverDragon24! Brother do u face this issue?

Yes i did the same, cut off the top section so that it doesnt cover the sensor, working ok now!
nokia xl blank screen call
Hi guys, my XL got blank screen every I make a call, what happen...
Blank screen show in every rom I've installed, but not on stockrom, at stockrom blank screen call only happen once after that going normal...
I'm not using screen protector at all...
What's wrong, how to fix that ??
this problem is in NOKIA X stock rom..
other roms doesnt have this problem..
its a bug in stock.
Hi, I've searched this forum and the Internet in general about proximity sensor problems but it seems like basically every problem that someone else had was fixed by removing tempered glass/screen protectors/cases/covers. I'm having a proximity sensor issue and I'm not using any screen protector or case.
This has happened twice now. Once when I was listening to visual voicemail, once when I was making a call. The screen goes dark and will not respond to any wake commands. Every now and then it will turn on for half a second when I hit the power button but then turns back off again. The first time when I was listening to visual voicemail, I had to hard restart the phone by holding volume up and power. The second time during the call, I managed to hang up the call in the half second the screen came back on, which ended the problem.
Right after that, I tested the proximity sensor using the SMMI test (calculator .12345+=). The test makes you put your hand near the sensor, then away, then near again. During the test, the phone immediately sensed my hand near the sensor except that my hand was nowhere near the sensor and there was nothing else near the sensor either.
I did a reboot and ran the test again. This time, the test finished correctly. The phone did not detect my hand until I actually put it near the sensor.
I'm running stock everything except I do have root(ZE551ML). I'm leaning towards this being a hardware problem and I've only had the phone for a week so I'm well within my replace period with Amazon. Is there a solution to this I'm missing or should I just replace? I'm a firm believer in troubleshooting first. Plus, setting up the phone the way I like again will be a huge PITA.
Thanks.
I would replace. It does sound like a hardware issue, and your better off getting a replacement instead of a possible pain for the life of your phone.
I get the same, and the flickering screen happened once to me after I I have just put a tempered glas protector on it ... removed it and so far no problems, but who knows.
I think the SMMI test works correctly the first time you start it, and incorrectly the 2nd, 3rd etc ... dont think it is a hardware error ...
Hi all, i have a zen2 with this same problem, i think doing sensor calibration can resolve the issue... but i can´t found how to do, by code, or by app...
Any body know how to do calibration of sensor aproximty?
Thanks in advanced!
Ps. I dont have screen os glass protector...
i don't having tempered glass or any screen protector. my proximity sensor is not working. Even i checked .12345+= but it gives error in proximity sensor. what to do? plz anyone?
same problem
Hi to everyone,
I have the same problem with the proximity sensor.
After a device reboot, the simmi test work correctly, but after some hours the test fails.
Someone know as I can calibrate the sensor ??
Thanks
I just fixed mine, cause I was having that issue for a LONG time now.
I actually just stuck a piece of paper in front of the light sensor part of the sensor window on the screen. It's the right side of the sensor window.
To be more clear, a while back my screen broke, so I ordered a screen online and changed it. Ever since then my prox. sensor didn't work, so I couldn't use the keypad during calls (the screen would go black).
My screen still isn't attached properly, so it's just being held in by the floppy protective case I have on it right now. This allowed me to pull the screen away from the phone a bit and slide a piece of paper behind it right in front of the light sensor. As soon as I blocked the light sensor then the proximity sensor started reading properly.
I got the idea because I was trying to clean the screen, thinking that it might just be dust blocking it or something. That didn't help, so I tried cleaning the sensor, but had the calibration test running at the time, and it instantly worked!
So I kept playing around with it and noticed that every time I blocked the right side of the sensor, it worked, but as soon as I removed the brush I was using to clean, it stopped working.
I stuck a piece of paper in, and BOOM, worked just fine.
People might want to build on this and maybe try sticking a piece of tape over the right part of the sensor. I haven't tried it, and since I finally have it working now, I really don't want to play with it too much and mess it up.
Hope this helps anyone else having this issue.
Hi all,
I am using zenfone 2 laser z550kl. Screen blackout during call and did not come up till the call is cut. I changed only the cover of proximity sensor and phone is working fine. Change the small rubber covering of sensor and it will work.
Hope this will help all if still using asus phone.
Hey guys,
The proximity sensor on my G4, for some reason, causes my phone to turn the screen back off immediately when I try to turn it on in the dark. I took it to Verizon, and apparently they see this very frequently. so they would not just give me a new phone. I do have a tempered glass screen protector on my phone, and it covers the whole front, covering the proximity sensor. Is there anything I can do it solve this, it is super annoying? I basically just have to turn off pocket mode, but I cannot see any settings for that on the G4.
I saw another XDA thread that referenced the At&T model of this phone, they have a number to dial that gets to a service menu, that did not work on my Verizon G4.
thanks, any help is appreciated.
The glass screen protectors should have been better designed. The proximity sensor uses infrared (IR). IR radiation doesn't go through glass. So probably no way to fix it other than getting a glass cutter and removing that section of glass.
This one has cutouts for the speaker, sensor and camera...

Appears the updated version of the Yootech does too... These seems to actually have glass instead of just a entire piece missing above the speaker and sensor.

Well then what it seems like you have here is a proximity sensor that needs calibrating. [emoji6]

Hello to re-calibrate the proximity sensor you must be root and download shorcut master(lite) from playstore open and search for hidden menu and then go to de bottom and click LaunchMiniOS and continue with the original post: http://forum.xda-developers.com/showpost.php?p=63133124&postcount=3
