Invalid My ui system keeps crushing

[Odykan]

I have the redmi mi 9 nfc, and since I got it it's always crushing. Before I updated to 12.0.1 every app would crush after a while. After the update the crushes are rarer but still happening with the difference that now I get the message that says " system ui is not responding". What's happening?

Your post is unclear, are you talking about a Redmi 9, or a Mi 9 ? Are you using the Xiaomi.eu ROM ?

If it is a Redmi 9 (Mediatek) and/or are not using the Xiaomi.eu ROM, you should use the official Xiaomi forums.
