Invalid MIUI 12.0.9 redmi note 9 freezes

[usera]

Hey,

I have a redmi note 9 running MIUI 12.0.9 and I have the following issues:
1. Camera app unusable. The app crushes or the phone freezes whenever I try to open the camera.
2. Lock screen get all black at random times.
3. Phone is generally very slow and get stuck/freezes often.

This is a new phone and I updated the OS about 2 weeks ago. Before the update I didn't have these problems.
Are those known bugs? if so, when will they be resolved?
If not - what might cause this and how do I fix it?

thanks.

If you are pointing the vanilla redmi note 9 then you thread has no place here...you would better go ask on mi community scince you are using global rom and the fact that the device is powered by an MTk chipset
