Sony Xperia is one of the most popular devices these day, some clients. If you broke your ,mobile you will notice the touch screen is not working but you can see all images normally. This thing might have because a small crack is enough to let the touch screen irresponsive..
In the case you can see any crack on the touch screen you need to apply for warranty, do not try to flash the rom or install any special software.
my z3 dropped from my pocket, it has a small crack and the touch is not working, I think a cable is loose, could you please give me a quote to reattach the cable or replace the screen, thanks Kent
The installation cost 70 plus the screen price
