Tell HN: Xiaomi phone is showing ads after updating to MIUI 14

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)
