@Annaelle your hint was perfect & works fine for me, thanks so much. so good to have this forum!
@MHMH sorry it doesn’t work for you! i suggest you try it once more after “purging” that media storage app as @Annaelle suggested. and be sure you use a cable that worked before. for me, it took a while to re-install FP2 on my windows10 laptop…
update: i do get the connection, also repeatedly, but it isn’t stable, that is, it shuts down after a few minutes (= switches to charging mode). also, i have to always purge the media storage app before trying the file transfer. most annoying: FP2 shows up in my file manager but ‘internal storage’ and ‘SD card’ are both empty (which they’re not of course). like the others here i observed this issue after the september update (file transfer worked fine with the former android version).
summary: @Annaelle 's solution works for getting the connection but file transfer doesn’t work because the connection remains unstable. help?
