Re: F-Droid only if you can
Well requiring an open source code repository for all apps discourages the Asian scammers up front plus the apps are free. The drawback is of course a much more limited selection of fart apps (and admittedly other apps as well). To be honest a teen girl social butterfly couldn't probably get by with just F-Droid but its perfect for a back up out of warranty after market rom phone on which you don't want to have any sign on accounts.
