If they had full support for side loading, and supported the thunderbolt standard I feel most of my hardware problems could be solved with a type c case that's adds it a headphone jack and SD card slot
My list of problems: Too expensive, no 3.5 mm Headphone jack, no expandable storage, lack of foss apps and stores like f-droid, and the lack freedom to install and do what I want with the device I payed for.
Prob for Android but not likely on iOS
