I thought the same about mine as I did not suffer from many of the past issues other owners had but in the last month the once in a while failed recordings have become a daily event. I only use mine as a PVR no Plex nothing ever transferred to it or from it and it not even on a network with Bluetooth and WiFi disabled strictly Ludite mode with the only exception being online via a cable.Mine upgraded yesterday and it seems to be the same as before, maybe a bit snappier as others have mentioned.
I am one of the few with a good one then generally behaves itself. I only use it as a PVR and SmartTube and Plex.
The only issue that has appeared is that when I use Apps I get the resolution window permanently in the top left corner. Usually I get it when I first start an app as it switches resolution, but now it stays there. The only way I can get it back to usual behaviour is to switch off at the mains and restart.
It doesn’t stay there on live TV
