Xperia SP multitouch problem?

Hey,

I have a problem with my Xperia SP's multitouch ability. Basically when I hold one finger to the screen and then try to tap another one, there's a small delay in recognising the 2nd finger. This means that in order to recognise the 2nd finger, I have to hold the screen for a bit, which makes it impossible to play games like Fifa 14, MC4 or Shadow Fight...

It's weird because I've never had this problem before...it only just started. I've tested this with a moutitouch test app from Play Store.

Apparently it happens right after I open a random game (any game). To fix it I have to restart the phone and not open any app, which is just crazy.

I tried factory reseting, upgrading to a newer version, killing all processes except the needed ones...but nothing worked.

Any ideas?

Thanks in advance

If you dropped your Xperia,probably that is it.
I think you need to replace your touch screen !
Hope this helps !
