I just reinstalled on an Xperia 10 III, normally I put over a collection of apks from an 10 III running android, open the files via file browser and hit ‘install’.
This time, all the normal apks just showed up as installed (they are in the app list), but half of the files were ‘apk+’ and have no install option at all, and cannot be run.
I can’t find anything about this in the forum, any ideas?
