Awkward battery charging and no connection to PC

ANd any advice to repair data transfer function ?

But you know and do this, right? …

USB connection to PC: FP2 icon appears, but "this folder is empty"

When connecting the phone you’ll get a notification on your phone as well. Tap on it and you’ll see different options what the phone can do with this USB connection. Default should be charging only, so you’ll need to switch to MTP, then your files should be available again.
