Touchpad has worked great for years now.
A couple weeks ago, I hit the rotation lock button on the system menu and oddly after hitting it, the words "Turn off Rotation Lock" disappeared from the button. The icon would remain. But the place where the words were would be blank and the button would no longer work. If I rebooted, the button would return normally, but again if I'd actually hit it, it would work on the first tap but then the words would disappear and it wouldn't work again. Very annoying since I'd have to reboot every time I wanted to change the rotation lock status.
I then noticed a similar thing was happening with the Mute button too. I also noticed airplane mode would not work although the button itself always looked normal. All the other system menu buttons worked completely properly.
Then somehow, it got fixed suddenly. I tried a few things to fix it. I did hard restarts. I let the battery go to 0 and then recharged fully. None of them seemed to work. And then when it suddenly started working properly I had no idea what had fixed it. But I was just happy it was fixed.
For a couple weeks it worked perfectly again.
Then the other day, out of nowhere, completely randomly as far as I can tell, the same problem started again and I can't get the system menu back to working completely normally again.
Does anyone have an idea why this is happening, especially so seemingly randomly? Any idea what I could look into to figure it out? And any idea how to fix it? I really do not want to reinstall the system or anything like that since I have a lot of customization set up on this. And it already fixed itself once before without needing to do that so I'm hoping to do the same this time.
I really appreciate any help.
