Your Xiaomi Redmi Note's lock screen has become a billboard? You're not alone: MIUI users regularly encounter intrusive banners that appear when unlocking their phone. The manufacturer integrates ad modules into system software to monetize cheap smartphones, but not everyone likes it. The good news is that you can turn off ads without root rights using hidden settings or third-party tools.

In this article, we will discuss 5 working ways to remove ads from the lock screen on the Redmi Note 8/9/10/11/12 and other models running MIUI 12-14.
