========================================
I made the silly mistake of trusting Asus to have a stable Android 12 Update. Unsurprisingly, I was wrong. Android 12 is garbage.
How can I downgrade back to Android 11?

No problems at all for now but still testing it. Performance is descent and solid via armory crate advanced tuning profiles. Better than a11 Antutu score. Cant prove right now but looks like battery was improved. Antutu shows 5800mah. Need to test camera and sound. Also need to test calls cause smtimes on a11 can't hear ppl.
