I've updated my Xiaomi phone to MIUI 14. It lost the ringtone I've set, so I had to set it again. Before selecting the ringtone, it shown a full screen ad, then another ad after selecting it. This is not a free app from Google App store, it's Xiaomi's own system.
I don't want to install a custom Android image. Is iPhone the only alternative to getting rid of ads trends? (Samsung TV also has ads)
Both Motorola and Google's Pixel are better alternatives than iPhone IMO and neither will show you ads if you don't explicitely install an app that shows them.
