Home button strange problem - Lenovo P2 Questions & Answers

Hi, a few months ago my home button gets a "lag", just not working. Then everything was ok. But now again it stopped working and probably forever. I can click to go to home but do not read the fingerprint and do not work gestures .. what can I do in this situation? The replacement of the button is rather off, because I have broken glass

Power button sometimes takes me to lock screen?

Sometimes when I press my power button, wanting to power off the display, I instead get the lock screen. Has anyone else noticed this?
Start position is just the home screen.
Found another thread with similar issue but in that case it's a HTC EVO.

Is it possible that the power button is registering 2 presses, instead of 1?
What if you start with the phone turned off, then press the power button? Does it turn on, then off again?
I'm never able to reproduce it at will but I suspect you are right.
Sometimes the press on the power button isn't registered at all so I suspect it's a hardware issue.
Have noticed it since day one and I have had the phone for a month now.

Got it back from LG authorized service center now. New power button and new camera glass (that was another issue I had).
All OK, it was a hardware issue!

Home button unresponsive on tab s 8.4

Hi there
Bought this second hand.
Was working fine, and all of a sudden the home button isn't working. I've tried a reset and a factory wipe/reset - still nothing. Google search doesn't really help. The back and menu buttons to either side of the home work fine, just the central home button which isn't working.
I know there exist software solutioons - but would rather get the hardware fixed/diagnosed.
Any help?
Thanks
I also have the same issue. My button is unresponsive, yet, the finger print scanner works. I was wondering if anyone had a similar issue?

new phone is not working properly - lg g4 (screen issues/power button)

Hi there,
I bought a new LG G4 and after 2 days it started to work funny. In other words if I wanted to press power button when screen was off it didn't give me any response, but after I took out the battery and put it back the screen goes on and same if I do plug the charger the screen goes on.
- I tried to run phone in safe mode and it works without any issues.
- I done factory reset.
I have marshmallow android version. and also I have tampered screen protector (but remember it works without any problem in safe mode and even though my screen protector was since the first day of the phone I bought)
p.s. just an update just realized it does the same in safe mode...
any help appreciated.
Regards
just a thought,if you press the back button and the screen doesn't turn on,it might be because the sensor is covered(near the front speaker).
I have brand new G4 also. S/N 602. And it does the same thing, it has trouble waking up for some reason every few times. Double tap or power button can't wake it up, only thing that can wake him is double press power button to start camera. Same thing is on Stock and on Cyanogenmod.

Okay, I took off the screen protector and it works fine now.
could be that a protector problem ?
You most probably have a protector that is covering the proximity sensor. That's why the phone did not wake up.

Hard press home button stopped working after rooting?

I bought my galaxy s9 960F last week.
I have rooted that but the pressure sensitive home button does not seem to work. I tried setting the sensitivity to maximum. Still not working.
Read somewhere that home button needs to be recalibrated. Any ideas.??

HTC 10 unresponsive - screen or on/off button problem?

Hello,
I have a problem with a family member's HTC 10. Today their phone somehow got stuck with a black unresponsive screen, as if the LCD and the touch matrix (sp?) were both dead. It wouldn't restart after pressing on/off + volume button (tried with both volume buttons alternately). When pressing home, the back button and the other one would light up as usual, but it didn't turn on the phone, and neither did the on/off button.
The on/off button seemed kinda stuck halfway, and it usually has a smaller press/unpress "distance" than the one on my own HTC 10, so I'm guessing it was due to a stuck button. Said family member loves taking screenshots and complains that the button works poorly.
Is this a stuck button problem? Is this fixable or should we throw away the phone and buy a new one? The phone started working normally on its own after a few hours, but obviously this is something that needs to be fixed.
Thanks for reading, any help will be much appreciated!
Edit: It was all hardware problems, ended up taking it to the shop and getting parts replaced, works fine now.
