faulty proximity sensor during call - Moto G Q&A, Help & Troubleshooting

When I make or answer a call the proximity sensor plays up , when I take the phone away from my ear the screen stays black and doesn't come back on unless I can cover the proximity sensor again,and even that will only work some times.other times I have to press the unlock button to get the screen back on. Any ideas or fixes, anyone else experiencing this ?tried a factory reset.

Flash Stock Firmware and Relock Bootloader and Remove Warning Screen and send the phone to repair if you still have warranty.
I had the same issue with another device, never got rid of that problem, only had ****ty ass workarounds only on Cyanogenmod possible.

Is there a hidden menu that allows the sensor to be calibrated ?

Not that I know of, sorry.

might sound daft but, if you have a screen protector is the hole for the sensor in the right place or even there at all?

You're right there's no hole, but I've had other phones and there has been no hole in the protector and it didn't affect it.

Mine was doing it intermittently, when I lifted the protector it was fine. Maybe the sensor is particularly sensitive?

Yes removing the screen protector fixes it but I need the extra protection so I still need a calibration fix.

Buy a different screen protector, one that has a hole in that area.

[Q] screen sometimes goes black and doesnot wake up ,when i answer a phonecall

no matter what buttons u press,it willnot react.
and after a few minutes,i could wake it up pressing power button.sometimes even this could not work
i may use my collegues phone to call me again to wake it
this condition occurs sometimes on some ROMs,not always,which make me confused.
i have searched our bbs,without answers.

are you using a screen protector?
if you are then you need to cut a hole in the screen protector for the proximity sensor

Did you ever follow the suggested advice and cut a hole in the screen protector where the the proximity sensor is?
I've used LBC mod for months now (without screen protector) and have never had this problem.

[Q] Proximity sensor issues with flap case

I bought three N5 for my parents and myself. The flap cases for the first two of them work well: when the flap is lifted up, the screen wakes up; when the flap is folded, the screen shuts down. However, the third one doesn't work well. Sometimes it works like the other two, but most time it doesn't.
The proximity sensor works well when I make calls. I also installed "Proximity sensor finder" to test the sensor, which actually detects the case accurately. But for some reason I don't know, the Android system doesn't shut down the screen even when the sensor detects a folded case. Anybody knows what the problem might be and how to fix it? Thanks.
Most proximity sensor cases have a magnet near where the volume rocker is. Do all three of your cases have that?
No, none of them has a magnet.

Would the phone in question happen to have a screen protector? Sometimes the screen protector can cause this issue if it isn't installed correctly. Make sure the proximity sensor/light sensor isn't covered by the screen protector.

They have to. That's the way they turn off the screen. It's not the same sensor that turns off the screen when you're on the phone.
Yes, there is a screen protector, which has a whole at the location of the proximity sensor, so it shouldn't be a problem. What baffles me is that "Proximity sensor finder" is able to detect the case cover accurately, but the system cannot respond correctly.

I see. This explains the problem. It seems that the tiny magnet in my case is not effective as it doesn't fold perfectly. Thanks a lot!

If you're 100% sure that the screen protector isn't obstructing the sensor then I would then clean around the area where the sensor is with a micro fiber cloth. If that doesn't doing anything then I would temporary switch the flip case with the one on your parents N5. It is possible that the case on one phone can be faulty. If that still doesn't work then I'd factory reset the phone.
And if that doesn't work... I'd get a warranty replacement. More than likely you have a faulty case.

I think I should blame the faulty case, as jd1639 and rootSU also pointed out. The magnet in the case is not effective. I believe what jd1639 has said, screen on/off during calls uses proximity sensor, but the response to case flap relies on magnet.

Edge's home button starts to peel

Hey guys,
I have the edge 4 months, and before 2 weeks ago the home button starts to peel. Its never got dropped or with keys in my pocket. I save it like my baby.
I feel very disappointed about this issue.
I'm curious if it's just me or more people has it?
Thanks
Are you sure its not a film cover on the button?
no for sure.. its peel
Could you provide a picture?

Hi,
A friend of mine had a similar problem -- was it like this: http://i.imgur.com/yS3tVTP.jpg. He sent to Samsung Concierge and they replaced the front piece entirely...

Hi, same as mine. I have micro-looking peel on my phone and it's only been more than a month or so.
Sent from my SM-G93FD using Tapatalk
Yes, picture please.
This would be totally unacceptable on a £600 phone.
I'm facing the same problem - few days ago I noticed something on the home button .I thought it is some dirt so tried to scratch it gently with my nail . Turned out it's the paint. I really hope that Samsung will replace the button. I got to say the quality of this phone is not adequate to the price .

Well, to change the home button on most Samsung devices, you have to remove the entire front assembly of the device. Once you remove an already applied front assembly with water resistant adhesive, the water resistance is compromised due to the adhesive getting damaged during disassembly. To make the device water resistant again, they need to apply a new front assembly with unused and undamaged adhesive. At least, that's my theory. I welcome any correction.
i have the same problem, my home butten dont click anymore, and i ask'd Samsung over here to repair it and they say its not warranty. the home butten is really crappy for a €800 phone i expected a repair from samsung and they wont do it. only if i pay the full repair. sad...
Half of my home button is peeled off, really wish there was better quality control with these high end devices.

Nice, thank you The only downside is when you use long-touch for screen of, when you want to unlock your phone it will not use your fingerprint, but the sample instead.

can oil go through the phone?? plz help asap

guys i installed a screen protector on my phone and it had halo effect on it so I saw a vid on youtube to apply oil on the edges of the screen which helpt
now after a week or two after applying the volume Up button is not working well I have to push hard and after a couple of days now I notice my power button isnt working well I need to also push it hard and not always the fingerprint works, could it be a defect in the panel which holds the buttons or did oil manage to go through and wreck it?
cuz my phone is in warrenty but im afraid to send it and they would find oil in it, so what do you guys think I should do please help asap

If you do a search you will find that others are complaining about their volume up button failing after the Oreo update. I find it hard to believe that the update had anything to do with it. I think it more a coincidence of a possible hardware failure more than a software bug. That being said...I doubt that oil would cause your issue and considering that others are having similar problems I would guess that a hardware failure may be the culprit. Then again...seeing that so many started complaining about the issue after the Oreo upgrade...I suppose there could be a connection.

Can you elaborate on that please? I'm looking to order one of these new screen protectors that require the front of the phone to be drenched in LOCA and I certainly wouldn't want the liquid to find its way into my beloved device.

Well, it depends on the oil, but most have a high creeping ability and displace water.
I can't say anything about LOCA, I personally used a foil protector with water application.

does it make sense if oil made it through to make my right side panel not function properly? i mean volume down works but volume up doesnt and some times power button makes problems...
pushing really hard makes a function but its not legit
is it oil or some thing else?
if its oil, how can I dry it out?

Unfortunately oil doesn't dry out...at least not for a very, very long time.
If oil has penetrated to the interior of your phone and is causing issues like short circuits, then the only remedy I can think of is the phone will have to be disassembled and cleaned out.

I already ordered one of the screen protectors you are talking about. I would not worry about the LOCA because as soon as it is spread out evenly under the protector you will be using the UV light to harden it.
I would say it's more than likely either a driver issue with the Oreo update, or the beginnings of a hardware failure due to manufacturing defects. The reasoning behind that being that 1) others have had the same issue, and do not have the same potential for oil in their phones, so it's unlikely that that is the issue, and 2) Even if oil did get in your phone, oil is not a polar liquid, so the presence of it would not do any immediate damage to your phone in the same way that water would (look up mineral oil PC builds if you don't believe me). I would say for now your best bet is rolling back to Nougat, on the off chance that it is a driver issue, and just being careful with your volume button in the future, on the even smaller chance that Sony decides to acknowledge and fix the problem.

The little dot in the top just off to the right hand side is my guess because if I cover that spot the phone will not wake with double tap.
