So I hate the new UI of A12, and theres a number of features that seem to no longer exist/work(scrolling screenshots, holding power button to bring up gpay, etc). Just wondering if theres a process to downgrade back to A11? Thanks
Yes, you need to backup everything, then load the correct a11 FW suitable for your carrier, IF your phone is unlocked that is.
You need to know the carrier, model number. If it is unlocked "RETail), you need the correct FW that matches your country.
There is another topic for loading stock ROM's
