Pls how do I update mine to android 13cand coloros 13

For those who can't update to Android 11 or 12 (stuck on Android 10) - there's an easy fix for that. Just get a free VPN app from the Play Store an connect to a free Portugal server. I didn't try other countries but Portugal should do ...

Does this device support 15-18W charge, I would never charge this with that ultra fast charger, but will a 15W charger damage the battery over time ?
