Accessibility options not sticking

Please can someone confirm this bug.

Accessibility Options when enabled don't stick once you close the window.

For example Tasker and lastpass.

Zenfone 2 power button sticking

I circled the switch in this picture (I posted this on reddit with the source, i can't post outside links here. Sorry for broken link, i don't have enough posts for proper links) imgur . com/JWUOnVc

Anyway, the switch gets stuck down and if I accidentally press it then the phone will just turn itself off and I can't use it until i get a pen/something small and put it in the little slot to pull it out, press it again, then pull it back out. It gets stuck all the way down, and my warranty is void due to it being over a year old, disassembling it, and unlocking the bootloader. I really like this phone, however this stuck power button is driving me crazy. Is there anything I can do to fix it? I really don't want to disassemble it to the point of removing the battery, but if I have to i will. Any way I can fix this?

Viper4Android Driver Not Sticking on 6P - Fix?

I think this is a long standing issue with this app and this phone.
You launch V4A, it asks you to download the driver, it seems to work, asks for reboot... You reboot, go back into the app and get prompted to download it again.

I remember a fix I found somewhere that involved renaming or deleting a certain file before rebooting or something like that? but I find it annoying to keep having to try and use that flaky fix every time I change/update my ROM so I just wondered if there was a permanent fix out there, like a V4A .akp just for the 6P? Or do we know if there's a better workaround out there?

Thanks guys
