No, I absolutely did not factory reset this early in the diagnosis prossess. When did CSI burn down and rebuild a murder scene before investigation.
In answer to the laggy question:
There is no perceived difference with: anything since upgrade, one handed operation + installed and on or off, or uninstalled (reboots after every state change with OHOP.
The one thing noticed is, since upgrade, a legacy flash aftwr thw OHOP is enabled flash that it will now replace thw native Android gestures. This does not happen on my S and did not happen on my A9+ until the OneUI8 upgrade, and subsequent OHOP upgrade.
Have tried all combinations including 3rd party launchers, just as an exclusion principal.
But, as side gesture back is Android core and OHOP is a standalone app, it leans to a fundamental flaw in the current A series (at least for tablets) in the OHOP implementation currently, or a gap in my testing (outside the evidence wipe pish posh.
Again, if tou want to suggest something I can try, pre factory reset that I migjt have missed, please let me know.
