Turn screen Off while you listen music for YouTube. Lock YouTube and watch your videos without interruptions.

Listening music in the background in YouTube is a feature in YouTube Premium, but with Touch Lock you get that for FREE and also you can really turn off screen, which will save battery from phone screen usage.
Touch Lock is also locking your touch screen and hiding software navigation keys or hardware buttons (including Home button), so that you or your child can watch YouTube videos without interruptions!
