I'm in Europe and had endless ads on my Xiaomi phone - normally for Xiaomi crap, like themes and games. I actively had to go in and turn off notifications for various Mi apps to stop them pestering me with notifications several times a day, but there are still full-screen ad interruptions in the stock apps like the file manager and notepad.

My Redmi Note 13 Pro Plus is nowhere near as good as my last Xiaomi - the ads seem to have increased, and the battery life has gone to shit after <1 year of usage. I won't get another.
