I’ve installed the same version of Duckduckgo from F-droid, latest available 5.273.0, one on smartphone, one on tablet, both Android 13, but tablet is LineageOS, rooted. Both are very much debloated and degoogled, eg Goo services removed.
In DDG setup there are different options for both devices. Eg on a tablet AI functions are missing, and some more.
I’ve already dropped on some clue about “dynamically created setup”, but why in DDG? Is there something like that in general? Could you give me some more info at start, before I dig in deeper in technicals?
