I have currently the following audio/ video problems with my vero:
slow video playback and audio out of sync when playing small 100-800 mb files, (1080p/4k remux movie files plays fine)
low volume when streaming through my wifes thai tv addon. ( worked fine before )
barely heard audio on episode 3-4 on series x, episode 1-2 plays fine. ( ep 3-4 also plays fine on on mac/streaming from nas to phone )
I just thought I should do a factory reset and hopefully some of the above problems will go away.
How do I do this the easiest way?
