As this still seems unclear …
In order to answer this question on would simply go to Smartphone Selector → Search for the device → then Command line | Install (in your case) → then look under Downloads → /e/OS build.
- Does the device have an official=stable build ? In this case no, so no OTA Upgrade of Android version.
- Does the device have a current Community=dev build ? In this case Yes – we see
So if one currently had for example e-2.4.1-t-20241009439852-community-gts4lv
there would be one more OTA update to e-2.5-t-xxx
. After that for this reason:
Community builds do not receive OTA Upgrade of Android version
one would have to do a manual upgrade in order Upgrade from Android 13 (T) to Android 14 (U) … in this case … to run e-2.6.3-u-20241218455570-community-gts4lv
