However trying to do a remote connect from my Android phone displays an old style telephone pad with numbers and letters (eg 2 ABC and 3 DEF) to enter the partner ID. (see screenshot below)
However there is no way to access the letter part of the keypad. eg one key is labelled 2ABC but pressing it 3 times to get a 'B' simply gives me 3 lots of '2'. There is no button to switch between numbers and letters.
