Portrait to landscape freeze?

[L_Boogie820]

Whenever I go from portrait to landscape no matter what I'm using whether its the internet or text, landscape will not turn back up to portrait and I don't know why.

Try and recalibrate the G-sensor with it laying flat on a table - I originally calibrated it while holding it and after would not switch back to portrait. Hope that helps
