Hello
I have an official flip cover samsung and sometimes when I open the case the screen does not turn on, but the 2 keys on either side of the home button turns on.
I have to close and open the flap 3/4 times so that the screen lights up.
I moved from mm to nougat but the problem remains the same.
thanks

Hello XDA,
I think I discovered a weird feature or a bug when ever you place your S4 on top of a speaker. I have a portable Jam XT soeaker and when I place my phone on top of it, facing up the screen goes black only showing the tine and partial top bar.
Will attach screen shots.
Any Idea what I stumbled upon ?
Heres the screen, new account, sorry.

The S4 has a magnetic sensor which works with the S-View cover.
The magnet in the speaker probably activates the sensor in the phone, thus the phone enters the S-View cover mode.

Hello!
Today, I tried to solve a problem with proximity sensor in my G2, which did not work at all. When calling and putting the phone to my ear, the screen didn't turn off, resulting in a lot of accidentaly declined calls. I assumed it was because the inner piece of glass in front of the sensor was dirty and foggy, so I used a tutorial (/watch?v=hPFBA24dR1w) to disassemble the phone and clean the sensor.
At first I discovered that the front LED and proximity sensor hadn't been plugged in, so I fixed that and tried to turn on my phone. This fixed my LED, which I thought was broken for a long time, however didn't fix the proximity sensor.
So I went back into the internals, disassembled the phone completely and cleaned the glass in front of the proximity sensor. Then I plugged all the cables back in. However, when trying to power the phone back on, the screen doesn't turn on.
The blue LED is flashing during the startup, and after several seconds the back notification starts flashing too. When holding the power button, the phone vibrates normally, so the phone seems to be working fine, except for the screen.
I went back to check all the cables, which seem to be connected fine (I can send a photo if needed). I noticed that when I press the power button, I can see some light through tiny holes in the back. Then I noticed the screen turns to a bit lighter shade of black when powered on. I assume the touch screen is working too, because when I try to double tap the screen, the front LED flashes.
I'd like to ask for your help. Is there anything I can try right now?
Thank you very much, and sorry for the long post.
I want my second screen to be on when the main screen is off. Second screen works fine when main screen is on. When I turn off the main screen, the second screen changes for a split second (you know how it changes to signature/time?) and then goes black. BUT it still works. From memory, I can swipe to quick toggles and turn on/off my flashlight and it works. But the second screen stays black.
This started after I replaced my cracked screen. After swapping it with a replacement, I was having a bunch of issues with the proximity sensor (second screen off when main is off, knock on wouldn't work, fingerprint wouldn't work, sensor app always said 0cm). I fixed these by moving over the little rubber gasket from my old screen, but the second screen still doesn’t work.
Second screen daily timeout is disabled. I wiped dalvik/cache from recovery. Rebooted multiple times. Opened it back up and reconnected the display ribbon cable. Tested the display and sensors from the hidden service menu.
Any advice?? I'd like to troubleshoot further before doing a hard reset (I have so many mods installed lol). This second screen is why I haven't upgraded the phone yet...
You forgot to put the rubber gasket for the proximity sensor back in. Without it, you'll see exactly the problems you are now. Search eBay for LG V20 Rubber Gasket Holder and you'll see the part I'm talking about. If you put it back in it will fix these issues. It's a common problem with the LG V20 screen repair.

This didn't happen before, but once I bought a magnetic flip case. The screen keeps turning off/on. Because of this I returned the case as it made my 6T annoying to use and now it doesn't happen. Then I tested the screen with a magnet and the same problem happens. When a magnet is close to the alert slider on the screen, it turns off and on when the magnet is away from the screen. Is this normal or is it just me?
