 Can I just check that all the people here reporting phone issues have
unlocked the phones? For example, if you need to enter a passcode or
draw a shape to use your phone, it also won't let a computer access it
until you enter the same code to unlock the phone. That's a feature of
the phone rather than a bug in Ubuntu (Ubuntu phones also do this). It
will also drop the connection as soon as your phone shuts its screen off
again after a period not being touched.
