[Solved] I bought an set top box my operator provided, and now I'm not just stuck with their bloats. My home screen has their app locked on top of favorite apps and rows. Also the backdrop has their logo on it. My home screen looks exactly like the screenshot below(by 9to5gg)
I used AIDA64 to check and it says my STB was made by SDMC with a feature called 'com.google.android.tv.operator_tier'.
Please help me if you can!
Some android devices had that, if you found the offending app, you might be able to disable it in the settings and reset to clear it
worked with my original mibox
