Thanks for the replies above.
Nope ... can't throw the thing in the nearest Klong ... It's my partners lifeline (her phone) and my pastime while I sit on the shitter and play Sudoku.
Oh ... Her's ... it's a Samsung Galaxy A or E or something.
Mine is some cheap Chinese Appo phone or something. Lasted a year ... and now the screen has 'dead spots' ... as in I can't 'touch screen' and do stuff.
Cabling... humm ... yes, we have now come to Thailand. Thought I was using the same cable as back in the wild West ... but could be wrong.
Damm ... there are soooooooooo many cables!
Could be a hardware issue, and, if so ... great, so much easier to fix.
Thanks for the replies.
