Hi
So one of my touch key lights suddenly stopped working. The back touck key light is working. But the other touch button doesnt light up but still works. I believe its the called the recent apps button or something like that. Yes i have tried changing the light duration settings. And turned power saving on off. And restarted the phone many times. And factory resetted it. I couldnt find this problem anywhere on the internet. Please help.

This problem has suddenly started. If I tap the power button, the screen switches off as it should. But then it doesn't switch back on, no matter how many times i press the button. I have to soft reset.
Please help.
Okay, I've fixed that, but I'm having another problem now. After the backlight is turned off after 1 min, it doesn't turn back on :/
UPDATE: It's only happening when the phone is charging. Screen won't turn on once it's off. Backlight won't turn normal once it's off.

hello,
how did you repair this?
Hi, everything was fine with my phone until two days ago touch pro gone wild.
before that when i pressed power button- screen off. That was just great, i didnt need to block it.
but now power button is not responding. when i press it couple of times only shutxp is showing - menu for shutdown, reset. Also i have a couple of problems with screen shutting itself and shutxp showing.
Is there any way to assign power button to screen off action?
Soft and hard reset didnt worked.
Thanks for any advices
Hi Ive had the Galaxy S8 about slightly more than a week, and Im facing this recurring issue whereby the pressure-sensitive home button starts to take light taps as heavy presses, and on some occasions when i turn off the screen, it turns on by itself thinking that I made a hard press. I can feel it as the vibration motors are activated. I tested it using *#0*#, but it works perfectly fine there. Anyone else facing these issues? Can anyone tell me if this is a hardware fault or software?
I've just witnessed it turned phone off and back on and back to normal now had over a week only known this happen once about an hour ago
Never seen it turn on my accident, but it does glitch out sometimes. At times it can register a touch as a hard-press, and it does the double vibration every time I touch the home button. This is fixed with a screen off - screen on switch though, so not a problem for me, and I haven't experienced it after the new update
Got myself the S8 secondhand and while it looks immaculate, I also have this problem. At times the pressure sensitivity doesn't work at all, sometimes it will go through periods of immediately pressing and depressing, and sometimes it'll register a soft press of the home button as a hard press.
Think this is a hardware error? I've tried this in Ultra Power Saving mode and without my case on, and it's always repeatable.

I'm having the double vibration when I hard press the home button problem. It's a hardware problem? And how to fix it? I didn't understand the screen off - screen on switch solution

Double vibration? Isn't that what is meant to happen? The first vibration when pressing down simulates a real physical button being pushed down, and the second vibration when lifting your finger simulates you releasing the physical button. It's meant to happen, and it's not a hardware or a software problem.
What I meant with screen off - screen on solution is simply turning the screen off, and turning it back on again. It fixes a problem that occurs to me at times, where the double vibration happens every time I tap the virtual home button. Normally it's only meant to happen when pressing the virtual home button forcefully, not on light taps where no pressure is applied.
If the phone is in standby, with display turned off, if you double press the home button, or you keep it pressed, the phone will get back to phone mode with emergency call only. How to disable that damned festure? ?
Hello everyone,
I bought a LCD replacement for my OPO, and asked a friend to replace the screen (he had his own OPO, and changed the screen on it a couple times, so I trusted him).
The frame was not included, so the phone is without it unfortunately.
But I have this problem with the screen itself...
I boot the phone, everything goes well, it boots, everything ok, I can do everything...
Then the phone goes to sleep after the 30s, and sometimes when I press the button to turn it on, the lights in the bottom light up, I can hear sounds, I can swipe to answer calls for example, but the screen stays all black.
If I press the power button to turn it to sleep mode and then click again to wake it within 1 or 2 seconds, it works everythime.
Its just when it goes to sleep... And then I have to press the power button to reset the phone, and it boots again.
I'm using the LineageOS Rom, and I never had problems like this before replacing the LCD.
What caused this? Could the screen be "broken" when I bought it?
Thank you for reading this and for the help!

Well,clearly the issue is lcd itself.Happened with me on my last screen replacement,it was defective.Though in my case,I had to power on/off the device to get the display back.Get a refund or replacement,there's no other alternative.
Hi all. This forum came up in a search and wondering if anyone can help. I have an Xtrons PB7839BP head unit example for specs - ( https://www.aliexpress.com/item/32849856346.html ) where the on/off button wasn't working, but the volume on the same button did work. I tried to mess around doing an panel button reset and the unit started to reboot but didn't come back on.
Nothing happens on switching on the car, no button lights or nothing. The unit does come alive when selecting reverse and the reverse camera starts, all the buttons light up but am unable to do anything.
I've tried pressing the RST button in both its dead mode and where there is power with the reverse camera on. I was unsure how long to do this and tried several time with longer intervals. Where the unit is dead and doing this, the lights only blink on releasing the button, but nothing happens. When doing it with the camera and power seemingly on, it immediately closes the camera and all the button lights go out, with still nothing happening.
Not that great with these things, so if anyone has any suggestions, I'd be grateful if they explained it very simply !
Thanks
