I scan nearly all the crap that comes in through my (physical) mailbox and throw it away. My trusty Brother multi laser thingy sends it to me per e-mail and I can sort it later, when the PC is on. Once a month or so, I need to print some pages and it does that, too. Awesome thing, wouldn’t want to miss it.

It is faster, doesn’t crash and you can read the answers to all comments. It lacks some features of NewPipe like the display dimming via swipe, but has some UI advantages (sharing without timestamp, you pain in the ass!).

Long time NewPipe user here, have you tried FreeTube?
