Samsung GT 7.7 hung after charging After charging my Samsung GT 7.7, I switched it on but it just showed the "Samsung Galaxy Tab 7.7" and stayed like that like it hung.

What do I do?
If it has a removable battery, remove the battery, put it back and run it. Else wait for it to discharge then charge and turn it back on. If none of these solve your problem, boot to the Recovery Menu and factory reset your device.
