NOTE 7 PRO (Violet) RAM, HEATING AND BATTERY DRAIN ISSUE

[imseraj]

I'm using redmi note 7 Pro after updating on 3.10. I'm facing number of issues.

1. Heating: heating problem is not there in 3.9.
2. Battery drain: battery drain is also not there in 3.9.
3. RAM: i think I'm facing ram management issues in past 2 version 3.9 and 3.10. This problem was not on 3.8.

And a request can you please provide me the way how can i flash previous version of Rom like 3.7 or 3.8. I'm facing error when i flash.
