I have a problem with typing Sometimes when I am typing the keyboard suddenly vanishes and the blinking line at the place where I was typing also disappears. Even after persistent tapping it doesn't respond (right when I was typing this very sentence it happened). It doesn't matter what keyboard I use, be it Swiftkey or Stock Android keyboard.

Can someone please help me. I really want to see my phone the way it was before.
When mine does this I am able to double-tap on the input field and the keyboard re-opens.  (To clarify: regular tapping does nothing for me...I could tap it all day long and it just stays closed.  It's the act of doing a solid, clean double-tap which seems to instantly being it back.)

I have no idea why this happens, but maybe this will help you too.
