This is because we use the native InputLayout and the animation shows the flick.

• The error for email on the register screen keeps on updating while I'm typing.

Can't be possible in current scope of ticket as on rotation the screen refreshes and we have to maintain the fields data and states.

• Add Support for Landscape mode.
