I've got a Samsung Galaxy A51, which is now connected via USB, i get a Phone and a CARD folder (as it's having a micro-SD in its slot)
I can perfectly manipulate and browse through all directories manually (copying, replacing, ... all no problem)
but i cannot execute a search (i'm looking for an important PDF i once saved from my government's website through mobile connection (2FA so secure but i forgot where i saved it)...
It must 've been with my firefox browser (as that's the one i use) and i can't find the files in /download(s) on the card or the phone..
so two things can help me; 1) fix searching on connected devices from samsung 2) find the directory where ffox saves (but that is not for this forum, I know)
I'm willing to help you guys with output logs if needed (tell me which and where to find it, i'll send/add it), but my limits stop where debugging with debugtools for code starts so that you know my techlevel a bit (i can do all but coding would've been shorter)
update: i'm an very experienced user btw; using since the days it was still Windows Commander back in the '90s
