I've tried to change my lock screens settings multiple times to remove anything which would allow the phone to activate accidentally (trusted places, on body) and yet, ALL THE TIME, I'll have my phone in my pocket, locked by pressing power key to turn screen off, and it'll pick up touches against my thing through my pocket and start randomly doing things like writing crazy messages, pocket dialling people, changing the playing music, etc.

I've removed widgets from the lock screen but it seems like it must activate the phone, unlock it, and then pick up random presses.

Any idea what I can check/do about this? I was annoyed about how sluggish the fingerprint login is, and was looking to try to change it to stay unlocked more (where I could just tap the power button to wake the screen) but now it unlocks despite no fingerprint nor face.
