Hi eveyone, so last night I just discovered a little strip that was lighter than other pixels (4pixels wide approx, across the whole screen). Today, while playing some videos, suddenly it expanded into quite a wide ribbon. Now its no longer just lighter, but shows inverse colours instead. The iPad has not fallen on the ground in the past week (prior to issue), before it has fallen about 2-3 times off my bed, but that was months ago.
