New Freeze and drains battery - need urgent solution


Dec 31, 2019
I need an urgent solution to the problem of freeze on my Mi Note 10. I can't use my cell phone and I can't lose data regarding access to banks in Brazil because of the pandemic situation, the banks are all closed to enable operations of great value. Please help.
I cannot do a clean installation. The problem with version 21.3.24 is quite serious. In addition to the freese and black screen, the battery also drains very quickly. You can't go back because the problem gets even worse.
