so, I got my s10 today and after the first start it’s crappy, buggy and slow af… how do I fix it to be faster? which settings should I change etc?
You could wipe it clean using the bootloader and do a factory reset.
Original: Android 9.0 “Pie” with One UI 1.1 Upgradable: Android 12 with One UI 4.1 go to settings software updates
Why I flash. Too many OTA upgrades without a fresh start.
Every time I haven’t, I’ve regretted it.
Probably a dumb question but have you ran all the updates for it.
I only buy older phones. Current phone is a Note 10 plus with a minorly cracked screen.
I always reflash the system using Odin when I get a “new” phone. Smooths things out.

Is it slow after a factory reset? Which phone are you comparing the s10 with?
