Hi @aman12, sorry to hear about this.

Are you using the pre-installed keyboard app (Gboard) on your phone or have you downloaded another keyboard app from Play Store? Also, have you been able to carry out a quick test of the touch screen? In order to do this, find and tap Settings > Support > Xperia tests > Touchscreen.

Please return with this information and we will do our best to assist you!
