The touchscreen capability on my M532 (v4.0) stopped working a few days ago (2 weeks after the 12 month warranty expired). I've no idea why this has suddenly happened. It means I can't type the entry password or do anything with it. I get an audible click in the password field when I tap and if I hold my finger down I get the cursor showing but no keyboard appears. My next step is to attach an external keyboard/mouse, either via docking cradle or Bluetooth - either of which I'll have to buy (and maybe Bluetooth won't work if it hasn't been configured?) Or can I use the micro USB port to connect a USB keyboard via USB adapter? Or would factory reset fix it?
Any suggestions as to cause or fix much appreciated.
