I didn’t have any issues after updating my NP2. My 25 W Samsung charger charges the phone just as fast as before, but now I can finally apply a charging limit of 80%.
The new quick settings layout is not for everyone I guess, I don’t dislike it, but I just think the old layout was better. As for the rest, nothing is really forced upon you: If you don’t like the new clock designs of the lockscreen / AoD, just keep the old one, like I did. If you dislike the new font in the settings menu, you can revert back to dotmatrix style. If you don’t like that AI app drawer, you can just disable it.
