Proximity sensor problems

Hi people
I have a problem with my proximity sensor. The screen isn't able to turn on doing calls. I have looked though lots of forums, but without any luck.
I'm on the Vanir-rom so i'm not able to calibrate it though the secret menu.
I have tried different proximity sensor apps a they tell me that the "last distance reported" is 3 cm no matter what. It does though turn to 10 cm if i press around the proximity sensor.
It's properly a hardward problem, but what do you guys think?

same is happening here. but my sensor is working fine during calls and after calls. maybe u have something covering it ? maybe a screen protector ? but if there is a way to calibrate it in any custom rom , id love to know it too.

You should see the screen protector, I dont think that it`s that perfectly put on the phone.. If it is there, just peel it off..

u cant miss it its like an invisible tape on the screen. but i dont think thats your case. i cant believe there is someone in the world that uses a phone and hasn't noticed if the screen has a protector or not. anyway i cant really help on that.
personally here my phone works fine so i dont know...

Okay. That was also my conclusion.

[Q] Screen won't unlock during phone calls.

Anytime I make a phone call my phone locks. I know phones typically go black when it's at your ear, but when I pull away, it won't wake up/unlock. The only time it unlocks is at the end of the call. I set it up so that the power button will end my calls but that doesn't really fix my problem. If I have to use the dial pad during the call, I can't.
I read that the proximity sensor might be blocked by a phone case. I removed mine and it's still not working. Any idea what it can be?

Do you have a screen protector? If so, remove it and try again.

I am something similar happening, when I remove the phone from my ear after a call I cannot end the call because the phone is locked and I have to unlock it with a pattern before I can end the call or wait for the caller to hang up.
Interestingly I also have exactly the same issue as I had with the LG G3 as well, I take a photo and, if I do not have WiFi, the Nexus 6 turns off, it does it every single time - it's fine if I put it into airplane mode though. As this was the same thing that happened on my LG G3 and no one else is reporting this on Nexus 6, I am assuming it must be an app I am installing ?
Is that possible ?
Simon.

I have the same problem, it's really annoying. My phone won't wake when I take it away from my head and it doesn't respond to the power button until the other person hangs up.
Hopefully it'll be fixed with an update.

I am having the same problem. Brand new Nexus 6 that's only a few hours old.

I got rid of my screen protector and it works way better now. Worth a try if you are using one.

I just now am having this issue too. Here's another thread with same type of thing I posted in: http://androidforums.com/threads/black-screen-after-answer-call-on-nexus-4.671499/page-2
Long story short since I already related my post there, I haven't had this problem on lollipop 5.0.1, now after sideloading 5.1, I have this issue. Screen protector is on, but never was issue before. Now all the sudden it's an issue. I feel like it has to be a software issue. Guess i'll need to test few more times before taking off or cutting screen protector; will update with more news.

Same issue for me. Never had this issue before the update to 5.1. Wonder if I can go back. I have had the phone since early December.
A little testing. Holding the phone away from my face, the screen immediately blanks when a phone number is dialed. Tried rebooting - no help. May try a factory reset.
Very annoying!

Definitely is the screen protector screwing with the senors like everyone is saying and you guys are simply ignoring. I had the same issues off and on back on 5.0, 5.0.1 and on 5.1, but on 5.1 it was permanent. As soon as I took the protector off, everything worked as normal.

As a brief work around - you can go settings - accessibility - select power button ends call. Works for me till I decide what to do. I have a screen protector on and yep it's covering the prox sensors. Once removed it works as normal. Need to find a new protector that does not cover.

Rooted, stock, with screen protector.
Was working fine in 5.0.1 now in 5.1 I have two sensor issues
1) Ambient display does not work at all. When I pick up the device or when I receive a notification sitting on a table.
2) When I receive a call the phone goes completely black. The screen will not turn back on until the call ends.
I do not want to remove the screen protector until I know for sure that is what is causing this.

A2CKilla. Much thanks. I did read, but it was odd it went from 0% to 100% failure rate after the sw update. I work embedded sw and that is very uncommon for a sensor. I wanted to make sure since I just flashed this morning.
I cut down the protector and everything is good.

*****UPDATE*****
Well A2CKilla, we all just wanted to avoid the inevitable and hope it was a software issue we could just "fix" instead of being a $10, god forbid more, for a screen protector. Always try the more simpler things first than to destroy others first (which I accidentally did btw with my amazing tempered glass, now I must find one that doesn't block the sensor. In my professional opinion, if a sensor worked while having a protector over it on a previous android version, why in the actual F*** would it not work on the newer ones, UNLESS they increased/decreased sensitivity on the code somehow? Well that was my first line of thought anyway.
Also tl;dr PROBLEM WAS INDEED SOLVED BY TAKING OFF TEMPERED GLASS (that previously wasn't an issue at all) AND NOW ALL IS NORMAL.
ps. sensor is literally right next to the top speaker grill on the left side. Best to find a protector that doesn't block that.

I really wasn't trying to sound rude at all with what I said, but seriously, there's many a thread about this issue way before 5.1 even came out, and every single time the screen protector was brought up to be the issue, but everyone had to try to find 101 ways for it to not be that, granted my tempered glass protector was less than $5 and I've already found one with the proper cut out for again, less than $5 so I was fine with discarding it, but for so many people to really try and deny something that was the clearly the problem really was sad for a moment. Once again, not trying to sound rude at all but this wasn't the first rodeo about this issue

Wow I never had an issue on 5.0 or 5.0.1 with my tempered glass screen protector. After spending all day thinking it was a software bug and reverting back and trying multiple sources for stock images and ota for 5.1 I decided to remove the screen protector and it worked! Cant believe how 5.1 made the proximity sensor sooo sensitive.

This is not acceptable behavior for the device. Mine worked fine, 0 issues before update. Now ambient display is broken and in call the screen goes black. This should be a non issue. My other phone has the sensor covered with a glass protector and it's not a problem at all. This can be fixed, since it was working before. Taking off the protector is not an option for me since I don't have a replacement right now, and should only be a temporary fix at most.

so it's not acceptable for a device to not work properly with something it was never designed nor intended to have? and maybe you were a lucky one because there were many people having this issue and I also stated that it was an off and on issue for me until it was permanent after the 5.1 update. Also, that's another phone, not the nexus, every phone has different settings for their sensors. And technically speaking it is an option for you to take it off, are you forgetting that your screen is gorilla glass???, a type of glass they developed to be scratch resistant, outside of some dust here and there, I've notice no difference having taken mine off until the new one gets here

Spigen tempered covers the proximity sensor, does not work

no cut out for the proximity sensor.
blank screen during calls regardless if proximity.
the fit is pretty good though but I guess I will return it

There's no cut out, but the screen still turns off during calls like it should, so I don't see the problem.

Yeah my Galaxy S5 tempered glass covers the sensors as well and was never an issue. It shouldn't be since it's clear glass.

Mine does this too...actually just posted in the Q/A section.
Phone will turn off before putting the phone to my face and not turn on after taking the phone away from my face. I am hoping that this will get better as the screen protector attaches better over the next day.

Are you sure this is because of the screen protector? Did you test it by chance before putting the tempered glass on?
I've seen other people reporting this, but they are saying its a bug in marshmallow and not the screen protectors. I will have my phone later today so I hope to test it myself.
Sent from my XT1060 using XDA Free mobile app

I just ordered the Spigen tempered glass myself, can we get others to confirm this is an issue of Android M and not the protector itself? My phone is arriving tomorrow.

Yes I am sure its because of the screen protector. Because it works fine before and after I took it off lol
Even if it is because of a bug... If you get it now, it won't work right. Until it gets fixed. That is all

This sounds a lot like the issue with HTC's M7 when the initial software of the device wouldn't work well with glass protectors. The on screen buttons were not sensitive enough to detect touch once the glass protector was applied. Then HTC fixed that through a software update.

I'm returning mine as well. Didn't have the issue every call I made (only made a couple of calls, very rarely actually call people anymore) but I don't want the proximity sensor or FFC being covered period even if it ends up being partially or fully a software issue. Looks like there are several tempered options, think I'll wait a few days and see what others are saying about the other brands.

Nothing wrong with your glass
Ok, so I am experiencing the same issue on a Nexus 5 running the latest update with no glass protector or anything. Phone goes dark when I put it to my ear and I have to manually hit the power button to turn on when I pull the phone away from my ear. Anywho I believe it is a bug and not your screen protector. I get my 5X today and I get my spigen tempered glass today as well. But if your proximity sensor is working with the glass on when you raise it to your ear then it should work when you drop it back down. Not working only when you pull the phone down seems like an issue with marshmallow. Proxy sensor seems to have a bug where its affecting waking up on a call from going dark. Test it out with the glass on your phone if you can cover up the proximity sensor and it effects the phone, then it still works.

Just tested this out with and without. It is the glass (now the glass is not sticking as well...oh well). The phone would turn off as soon as my finger goes over the sensor. would not turn on when i remove my finger. have to hit the power button twice to get the screen back on. speaker phone disables the sensor so no issues there.
Tempered Glass with Sensor Cutout I may try this one out next. I wrote to Spigen to see if they are going to resolve the issue.

I just tested the sensor without the glass protector as well. The sensor being blocked is the problem. On phone calls with the protector on, the screen wouldn't light back up for a number of seconds or until hitting the power button a couple of times. Without the protector on, the screen behaves as it should.
I'm thinking about returning mine and getting a refund and then buying the new version if they release one. Unless Spigen would just do an exchange.

That is good if the screen turns off when the phone is against your ear, and turns back on when you go to look at your phone to either end the call or look up a date or contact.

Pretty sure he means it turns off when the phone isn't close to the face. This means the lack of proximity sensor cut is blocking the sensor as if your face is close to it.

yes I know what he means, I have the screen protector and the 5x. I am having the same issue, the phone should operate as I described. It doesnt with the spigen screen protector.

Spigen SGP11775. Same issues as others. Sent it back. Will get something with cut outs.

I am also sending back my Spigen tempered glass screen protector, got the Pleson tempered glass in today and it's much nicer. Feels thinner and seems to have a better coating on it and the fit is perfect.

Phone calls

Hi, has anybody else experienced that their screen goes blank and doesn't come back on when on a call and what makes it worst is I can't hang up my phone after I'm done with my call. Basically I'm at the mercy of the other person hanging up when the conversation is done, the only way that I have resolved this problem is when I restart my phone. What causes this problem?

Do you have a tempered glass screen protector on?

Look to the left of the top speaker and you will see two sensors (proximity and ambient light). Is there anything covering these, such as a screen protector, skin, or case?

I do have a screen protector on the phone. Should I just remove it? I just find it strange that once I restart the phone that everything works as it should.

When I bought my first smartphone, a Galazy S2, I bought an expensive (£10) screen protector. All it did was attract grease and fingerprints, so after a couple of months, after a sudden attack of common sense, I threw it away. The screen was suddenly always clean and smooth, and on every phone I've had since there has never been a single mark on any screen. Admittedly I do look after it - unlike colleagues who seem happy to literally throw their phones on to tables - and keep it always in an empty pocket with no coins or keys.
It seems very odd to me that we have incredibly tough glass on our phones (see the many people on Youtube trying to scratch their phones deliberately) and yet we feel the need to reduce their performance with pointless pieces of plastic...? Bizarre...

It sounds like your sensor maybe going. I have always kept a screen protector on my device and never had issues until I used a tempered glass one. The tempered glass was to thick to allow the proper amount of light in which kept the screen from coming on when a call came in or when on a call.
I would run a logcat and try to catch it happening. This will tell you just what is going on.

First before you get ahead of yourself. Find out if it is the screen protector. It is a cheap fix if it works and cheap to replace if it doesnt.

Have you bothered to pull a log at as I advised? This will tell you. Have you tested it without the screen protector as I also advised?
Just because it is the same sensor (which I doubt) doesn't mean it is programmed the same way.

I am running a logcat now and so far I have not experienced the same issue. I'll see what happens this weekend.

I had the same problem some weeks ago WITHOUT a screen protector but it never happened again. Could be the sensor which fails sometimes or a software related error. Are you using the stock phone application and stock kernel?

If it's a Phone app bug the only thing you can do is deleting its cache and/or reflashing the factory image. If this doesn't solve it, I would say it's an hardware fault, but I'm still prone to think it's software related.

Screen goes black when calling or getting called

Hi.
I got this phone about 5 months ago, and i was not regularly using it to make phone calls... but unfortunately now i have to, since i smashed my main phone.
Anyway, it worked perfectly until last week.
Now, whenever i get called, or i'm trying to call someone, the display goes black. I cannot see who's calling and cannot answer the call, unless i drag the drop-menu (usually notifications are displayed there) from the top; and if i'm the one trying to call someone, the moment i press call the screen goes black and cannot use the phone until either the person answers and then hangs up, or i have to wait for that robot to finish it's speech ...
Games like CoD mobile and Lineage Revolution work fine, but i need to be able to use the phone now (
This morning i whipped the device clean, but it still does the same.
Please help.
Thank You.

I had the same problem turned out to be the glass screen protector I was using, if your using one take it off and try calling someone.

Do not buy the tempered glass screen protector from Nubia for the 3/3S. Customer service has admitted it interferes with proper operation of the proximity sensor.

Hello, thank you for your contact. After attaching the tempered film, it will have a slight impact on the proximity sensor of the mobile phone. It is recommended not to paste the tempered film.

Is there a way to disable the proximity sensor entirely?

maybe it's a little late but, I realized that by using a matte type mica the problem was solved
