Touch screen problem

[TwisterDrew]

I bought my Xperia XA1 recently and the top right edge is not sensible at all. I don't know why. I have always looked upto Sony for its quality. This is disappointing.

This is seriously getting annoying. I have got my phone after a long time from service center for repairing touch issue with so much difficulty in my work schedule. Now after a month or two, I'm getting the same touch issues at the corners and edges. My work schedule doesn't permit me to visit local center frequently. I'm sure that I will be asked to visit service Centre again.. It is tiring. I haven't expected that I would suffer to this extent with such expensive phone for the given specifications.

La pantalla no funciona bien del lado izquierdo y derecho de la pantalla , en especial cuando estoy usando el teclado. Ya probé todos los consejos del soporte pero no se soluciona. 

The screen does not work well on the left and right side of the screen, especially when I am using the keyboard. I already tried all the advice of the support but it is not solved
