[Q] Is my HD2 faulty?

hi
As soon as i make a phone call my screen goes off, now on my iphone it used to do this only when the light sensor was covered. to bringthe screen back on I have to press one of the black buttons in the bottom of the phone, is this a fault?

I had this problem after fitting a screen protector. removing it solved the issue for me.

The genuine HTC Screen protectors have 2 holes in for the sensors. I can confirm this does not affect the screen when making a call.
Are you using a screen protector which doesn't have a hole for the proximity sensor etc?
It may be it can't function right as it maybe seeing the protector as something close to the sensor, hence why the screen goes off.

I have a Vidocq screen protection and the phone wake up again when I finish the call...

Problem with proximity sensor

Hello,
I just got my nexus 4 yesterday. I have one major problem, when I'm having a phone call, I am not able to turn on the device (to check anything in the phone or even to close the phone call!). If I click the power button, the screen turns on and off instantly as if something is getting close to the proximity sensor.
How can I fix this? (I'm thinking if there is a way to disable the proximity sensor during the call?)
Nexus 4 16GB running stock 4.2.2 (latest)

Do you have a screen protector on it, without the sensor cutout?? i use to have the same issue...but later found out it was due to my screen protector

I do have a screen protection.. I placed it to align perfectly with the camera hole. It's made to be on the sensor so I figured it should not interfere. I'll try cutting a part of it to test.

Problem fixed after removing screen protection. New problem: I need a screen protection now.

Proximity sensor not registering movement/doesn't turn the screen back on

Hi,
Lately i have been noticing that the proximity sensor on calls on my s5 is not working properly. Once i answer/make a call, when i place the phone in my ear it shuts down the screen but the problem is when i take it away from my ear, the screen doesn't turn back on.
I tried the the testing menus (*#0*# or something like that) and when i placed my finger close to the sensor it detected, going green and vibrating but it doesn't go away from that state.
The only thing that changed was that i applied a glass screen protector a few days ago and im thinking it could be that, but its strange because its only when i back away from the screen that it doesn't register, so i don't know if that or not. Also, the protector is properly aligned and the edges are not on top of the sensor.
Anyone experienced this on their s5?

You have to change the proximity sensor or cancel it(cutting the flat)

I ended up removing the screen protector and it went back to working properly =/ I can't really put it back on now because it attracted specks of dust and it doesn't glue well now =/
Cutting it flat means it deactivate it? Because i find it useful for phone calls

Cutting it means deactivate fully, even in calls display stay on.

Ambient display not working/phone screen stays blank in phone call

So just got my 6p yesterday but it seems as though ambient display although turned on is not working ND when I answer a phone call my screen stays black during the call and won't wake up
UPDATE: so apparently it's because the tempered glass screen protector is covering the proximity sensor. I still have to actually test that theory out once I get a new protector but from doing some digging that most def it. Just a heads up I used the one by super shieldz so don't buy that one until they make a cut out for the sensor

Thank you! I never would've thought about it... I was having the same issue and I bought the same supershieldz protector. Just ripped it off, worked like a charm.

IMO it's a minor inconvenience, all you have to do is press the power button and I think I'd rather have it covered than have an odd-shaped cutout. What else is the proximity sensor used for?

Have you enabled your notification light and the ambient display?
Read that enabling both seems to glitch the ambient display.

Nexus 6P screen stays blank/dark because of proximity sensor blockage
The issue is the blocking of the proximity sensor. I purchased 3 Supershieldz Tempered Glass Screen Protector for Huawei (Google) Nexus 6P from Amazon for 3 Nexus 6P's. All 3 phones have issues of screen going dark and staying blank. Nothing wakes them up... i.e. pressing power button, volume up button, finger print on back. The problem is exasperated during phone calls. You simply cannot get the screen to turn back on once in a call! To see reviews and comments go to Amazon and search for "Supershieldz for Nexus 6P."

Always on 2nd screen in the dark issue ??

I bought a used V20 with a defective screen. I change it, everything work for fine, but i notice a strange behaviour with the second screen.
The second screen is always on and i can unlock it by only touching the finger print sensor. BUT at night (or in the dark), the second screen turn off and i need to press 2 times on the power button to wake the phone.
The Knock On feature doesn't work too in the dark.
The light sensor seems to work correctly.
I would love to post a video but i can't......
This is an issue or it is normal ??
Thanks for your help !

Sounds like Doze.

I don't find anything related to Doze or "standby" about this screen.

check "daily timeout" on Show when main screen off. Seem u turn this function on at night

Sounds like there is an issue with the proximity sensor (not light sensor).
It's setup to turn the second screen off as well as disable knock on if the phone is in your pocket. Even during daylight hours if you put your finger within an inch of the sensor when the main screen is off, it should trigger it.
It seems your sensor may just be messed up.

There are a few apps on the play store you can try to fix it if you are rooted. You could also try a sensor app to see if the proximity sensor is showing feedback properly although you might need to be rooted for the apps to show the proximity sensor properly (not sure). My note 4 had a hardware test in the service menu not sure how to do it on V20 though.

Same Issue
Edit: Resolved the issue. Please read this post. There is a small rubber gasket-type thing that sits in the hole of the phone's frame where the proximity sensor is positioned. That rubber gasket was not included with my replacement screen. I pulled the rubber piece out of my original, broken screen, and installed it into my replacement screen. I am no longer having issues with the phone in the dark.
I am experiencing the same issue. I have a T-Mobile LG v20 (H918) and I cracked the screen last week. I ordered a replacement LCD assembly and installed it myself. Everything works fine during the day or in a well lit room, but at night, in a dark room, I experience all of the issues you are reporting. I am finding other posts online with our same issue, but as of yet, no resolution.
Even though the second screen is set to always be on, at night, in a dark room, it turns off almost immediately after locking the phone. It is almost as if the phone is in a "deep sleep" or something, because the following also occurs:
Knock On will not wake the phone
Fingerprint sensor will not wake the phone
Even connecting to the phone via AirDroid / AirMirror the phone doesn't wake
Need to press the power button multiple times to wake phone
Providing a light source immediately turns on second screen and resolves all issues
