Mi11 Ultra - apps not reaponding / phone freeze


Jul 12, 2021
I have xiaomi.eu stable 12.5.12 on my mi11 ultra and most of my apps crash with the message : "app name" isnt responding , i have the options to wait, close or report. It happens quite often especially while I scroll reddit or fb, but also happen in revolut. After it occure, if i close that app and open it again it will happen again very soon. A restart of the phone seems so fix the issue for a while.
I want to know if its a software issue or my phone have a problem with the RAM.
