Need help with 2 issues

[flyingkytez]

How do I turn off auto screen off/on proxomity sensor during phonecalls?

Why do videos keep playing where they left off in the gallery and not start from the beginning? How to turn that off?

2 annoying things need fixed.

It looks like some variants don't allow you to disable the proximity sensor: https://www.reddit.com/r/lgv20/comments/5exa7g/disable_proximity_sensor/
