Can someone come in handy this infa who encountered the same problem. Version 6.1 with Google Play.
Primitive FTPd - for me it was one of the most popular applications! I enjoyed the time, but on older Android.
With the move to android 9 and 10 in the Xiaomi Mi 9 Lite, alas, if you select "normal file system" has become impossible to select the start folder phone storage. Stupidly did not even have access on / storage / emulated / 0. Additional sdcard not use. I rearranged a couple of times, did again, all permissions given all settings - does not help.
Yes, you can select the type of SAF storage, then working, but we need to process each time, and most importantly - absolutely turns turtle speed, as many modem internet remembered.
In parallel, he picked up his handy file manager, focused on pop and quite narrow-minded software called "File Manager" from the author of "Flashlight + Clock" (there are in Google Play).
There is that's really really primitive built-in FTP-server, which is not even protected by a password.
But it all just flying at high speed, such as reading a file list directories and transfer files itself.
So while I will use it, can Primitive FTPd when repaired.
