For me picture quality is fine. No any lag. We wait. Upcoming software update there will be got more chances. Anybody see in language section added English (India).
But in the starting after resetting the box it showing list of apps that are going to installed that’s it other than that I didn’t find any new changes
A factory reset is recommended but not mandatory.. if at all there is a software bug or malfunctioning feature right after the software upgrade, a factory reset would fix those issues.
