I like the new features it offers. I haven't had any issues besides the battery life and that's a Sprint Hub issue as described in another post I started. Biggest thing I like is the options now for the AOD where you can insert your own picture..I've been making a few of my own with Photoshop to match my Orange/Rust color case.
let me double check. there was a recent update that the OEM pulled due to some issues found but i cant remember if that was for the S8's or the S9's.
it was for the S9/S9+..so this one should still be good to go. was your phone purchased through Sprint, brought in as a BYOD or purchased directly from Samsung?
you might try taking it into a repair store to see if they can flash Oreo onto the phone..i think best buy does it as well. wonder why it didnt kick?
