Xperia X touch screen issues

[Bala13]

I bought Xperia Xf5121 from USA,When Network changes from 3g to 2g the touch screen automatically pressed multiple spots ,Looks like Ghost touch issue when network changes to 2g .
Let me know why its happening ,any issue with manufacturing?

That seems quite strange indeed.

Have you checked in safe mode for this behaviour?

If it still does it, try  performing a backup using Xperia Companion followed by a software repair using Xperia Companion
