iam currently using xperia T2 ultra tried to turn on "talkback" from the settings. The phone immediately became sluggish and unresponsive, and I am now unable to scroll. This means I can't disable the feature from the settings menu. Every menu item is highlighted with a box, and accompanied by a vibration. I have tried restarting the phone with no success, so I'm now in the process of repairing the phone using PC companion. Please please please help me urgently
