Since the last month, my IPad works erratically when I try and use it while it is charging.Once it downloaded an app, music starts playing randomly and it does not respond to commands unless unplugged. When I activate voice over or magnifying glass, the IPad doesn't react to commands, I then have to deactivate through accessibility from Itunes on my PC. The charger its a 12 volt, charges, then stops, I have to flick the on/off switch from the electric socket, then it resumes charging, only to repeat the same behaviour again. Sorry for this list of woes, would really be grateful for help. Thanks a lot.
