What does this mean for official support?
Possible? Sure.
Certain? Definitely not.
Support for 10 III was announced last May, so i wouldn’t expect it earlier than May 2023.
Would i buy a 10 IV now, if i had the chance (and wait for more than six months for official SFOS)? Probably. Without the support? That i honestly don’t know. But i guess it’s a good phone, even with Android.
