will the one plus 3T get android 10 or 9 ?
eOS 10 is far far away. eOS 9 could be, when there is an official Lineage 16 available
So you will have a good chance for an eOS.
But you can also build by your own. For official lis supported devices it.s very easy
oh i would love to do that but i have no developing skills but if there is steps i can sure follow
Have a look here
thank you very much will definitely try that
Good luck …
