Heads up on proximity sensor problem with Skinomi

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.

Proximity Sensor

This doesn't happen all the time but enough to start getting annoying. If I make a call where I need to use the keypad for input, I will hold the phone in front of me, start hitting the numbers and the screen disappears. The only way to get it back is to hit power, and it stays on for about 3 seconds and goes out again.
My wife had a Galaxy Nexus that had the same issue. Is this something that can be fixed?

Having similar problem....
add to that.. the proximity sensor doesn't always work.

The sensor youre talking about is the light sensor. The same one that auto adjusts the brightness. You should make sure it isn't being obstructed by anything such as a screen protector or smudges on the screen.

Not using a screen protector, but I am using a Seidio Surface case. I can't remember if it was happening before that. Might have to run the phone naked again and check.
My wife had a Galaxy Nexus on Verizon that had the same issue, but that was a while ago...
UPDATE: Having the issue whether the case is on or not...

Any ideas?

I don't think anyone else has this problem. It might be just a bunk phone. Take it to att and get it swapped

It's pretty common on the S3 as well. Haven't seen a solution. Drives my brother insane.

The best thing to so is to input *#7353# on the dialpad and select proximity sensor. Wave your hand over the sensor to verify. If it doesnt work, check your case or screen protector if any to see of its covering it. If it isnt, go to att to have it swapped under warranty.

In call screen keeps coming on?

Hey guys. My brother just got this phone and is having some issues. .. He's coming from Lumia 922.. So it shouldn't be too hard to impress him .. right? Well so far he has gone into airplane mode every call he's taken because the screen won't sleep and his cheek toggles to airplane mode. Is there any setting to help this? I want to give him a chance to like this phone, but if you can't even comfortably make a call without worrying about accidentally bumping the button maybe he needs to trade it ...
Any advice would be appreciated.

Does he have a screen protector on it? Sometimes those mess with the proximity sensor and makes the screen stay on.

I have a somewhat similar issue. I returned my first phone because I thought the proximity sensor wasn't working. I would be speaking on the phone, press my face to the screen and then would hear an ear shattering beep and then then phone would switch to speaker phone. This happened several times. I did have a screen protector on the phone but removed it. It continued even after I removed the protector.
I swapped the phone for a new one and all was fine for the first several days. Yesterday the problem started again. And, no, no screen protector this time.

I've noticed this with this phone, as well. I have a screen protector, but it doesn't cover the proximity sensor. That's in the metal above the screen, I doubt anyone's screen protector would affect it.
Sometimes when my face is literally pressed against the phone, and by proxy the proximity sensor, the screen still comes on and I can see it out of the corner of my eye. While it happened occasionally with my other phones, this has happened more in the week and a half I've had this phone than a couple months with the others. I think it might be a defect in the model if others are having this issue.
I've also had it turn on the speakerphone for no reason even when it's pressed against my face. Don't know if that's part of the issue or not.

Well it's nice to hear that I am not the only one having this issue, but frustrating that I am too. . If anyone finds settings or a solution let me know. . It's definitely annoying.

Must be a limited issue. Haven't heard of this from anyone I know and I have yet to have the issue.

I think I may have figured out my problem. I had an "el cheapo" TPU case (http://www.ebay.com/itm/Transparent...r-for-HTC-One-2013-M7-Accessory-/330949139388) on the phone. Today I put 3 different callers on speakerphone & mute simultaneously. Took the case off and haven't had a problem since.

screen turns off after I turn it on

I'm having a problem where in low-light areas, my screen turns off a second after I turn it on. The only way I can get it to stay on is by plugging the phone in or unplugging it if it's already plugged in. It seems like there's an issue with the light sensor / proximity sensor that helps keep the device off when it's in your pocket. I'd like to fix, disable, or remove this feature. Anyone else having this issue or know how to fix it? I've encountered it before with the lightflow app where the solution was to remove lightflow, but this is built in which makes it more difficult. Fyi My phone is rooted.

No suggestions for a fix, sorry. I saw behavior like this (screen turning off) when I put mine in an arm band case with clear plastic covering the whole front of the phone. I assume the proximity sensor thought the phone was in a pocket, etc.
The only thing I can think of to simply learn more about the problem is to install CPU-Z and look in the Sensors section to see what the LGE Proximity sensor is reading.
A screen protector that covers the sensors can also cause this.

I get this in low light, too. I have to point it at a light source to get it to turn on. Very aggravating. The longer I use my G4, the more flaws I find.

Do you guys have a tempered glass screen protector on? I have this too, and confirmed this is what it's from. When I had one that didn't directly cover the sensor I had zero issue. It may also be that the sensor isn't that great or polls on too slow of an interval.

Interesting. Does this happen in no-light situations as well? Or is there is a "dead zone" between normal light, and pitch dark?
I tried mine in an almost-fully-dark scenario, in a closet with the door almost fully closed. It turned on normally using both the power button, and double-tapping the screen. Mine is a Verizon model, 610B software.

Thanks @RedOCtobyr for pointing out it could be the screen protector

Yes! I have the tempered glass screen protector. I'm going to remove it now. Besides this whole light sensor issue, I absolutely hate this thing. Compared to a plastic screen protector, I can barely move/drag my finger across the screen because it grips my finger so much. I also feel like it messes up the touch sensitivity so that a lot of lighter touches don't register. Whether that's true or not, the excessive grip this thing has on my fingers and this whole sensor issue is reason enough to tear this piece of crap off.
...
Yep. Light sensor now works in low-light situations but detects when it's being blocked in close proximity. It feels a lot better to touch the screen now as well. Anybody know of a good plastic screen protector to order off Amazon?

I love my tempered glass. Just not ones that cover that silly sensor. I can't say for sure but I feel my G3 glass also covered it without this issue, or at least from what I remember.

how did you over come that issue with the armband. i am having the same problem right now thanks.

Follow steps below to re-calibrate proximity sensor(must with the glass protector is installed and which is sensor covered up)
1. TYPE "277634#*#" in phone dialer. Hidden Menu screen will show up.*
2. Select "Device Test"->"MT", it will show "system will be restarted", then choose OK.*
3. After reboot, GENESIS MiniOS 3.1 screen will show up, press "individual item+power" while power button is pressed.*
4. Next, find "sensor test", enter it(do not block the proximity sensor), the proximity sensor will be automatically calibrated. Then block proximity sensor two times to exit.*
5. Find "Back to the MainList", enter.*
6. Press "Normal boot+power" while power butten is pressed to reboot system, done.
Now the problem should be solved.

Thank you for this. Although on Marshmallow the Hidden menu code has changed. I found this on reddit which helped.
User: Tramagust (I can't link because I have not made enough posts yet )
"It is *#546368#*MODELNUMBER#
So for the international version it is *#546368#*815#
For the Dual sim version it is *#546368#*818#
I assume for the NA version it is *#546368#*811#"
I will see if it makes a difference. Cheers

Yes that code is for lollipop.it is different as you said for marshamallow.

Proximity Sensor fail

Often when I'm in a call I can feel the haptic feedback going crazy.
I realized tonight that it's not working properly, because my ear or my face must have hit the mute button.
This isn't the first time it has happened.
Anyone else experienced this? I think the screen turns off, or maybe it doesn't, but it is not preventing my face or ear from interacting with the phone X"D
I think that holding it to one ear causes this to happen more than the other because the proximity sensor must be on one is the sides.
Any ideas how to fix?

Do you have a screen protector on? They can sometimes interfere with the prox sensor causing it to shut off during a call when not near your face, or what you are describing where it doesn't shut off at all.

The same thing happens to my pixel 3 xl as well... I'm using a whitestone dome screen protector, but don't know if it's because of the protector.

No screen protector.
A simple ringke case, but it doesn't affect the front of the phone.

I have the exact same issue. I was never able to resolve it. Factory reset didn't help. Ended up switching to a 6T.
