Sometimes mic not working when call somebody. After 546 update

Every time it happens i had to reset my phone but it happens alot.
Did somebody noticed that issue

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.

[Q] Getting LTE icon sometimes while on wifi

Recently updated to OA8 5.1.1 and having a weird issue.

While connected to wifi every 20 seconds or so the 4g lte Icon shows up, sends a bit of data then turns off again. Turned off download booster, volte is off, the setting that lets 4g take over for bad wifi is also turned off. It doesn't seem to be using a lot of data but it has gone through 1 or 2 mb in the past few hours.

I also tried freezing the Caller ID app like suggested in a HTC One forum but that didn't help at all.

Anyone else getting this?
