What’s next?
So far this is how I view all the updates done:
Last good version of Android: 7
Last acceptable version of Android: 13

Linux mobile distributions are probably not yet fully usable and I don’t see another alternative. Perhaps it will get better than Android and iOS just due to them getting worse. I wish Nokia kept it going with phones like N900.

Good. Android 6 came out in 2015 and 98.4% of devices in use now are at or above that level.. The only reason developers would have to target an API level that low in 2024 is to exploit something.
