My screen cracked as well. The touch works as it should. I had touch lags and ghost touches or missed touches as the mobile would detect touches in places where I would not even touch. Sadly I delayed giving it for the warranty repair and end up with a cracked phone one day.
Now my MicroUSB port is not detected in the computer so can't update to Marshmallow. My M4 updated so I know C4 must be out as well. OTA is not yet available.
And just until recently even the battery is loose, I have to apply a moment of pressure behind to start the phone. And after some hours when I get back to the phone it would have been shut off and I have to repeat by applying pressure behind to get it started.
I have extended warranty but they can't repair all this because they say once the broken screen (my fault) is removed, they won't be able to assemble it back. Also the entire assembly comes along with all the other parts so they can't just charge me for the screen but many things inside as well and behind.
Why can't Sony provide only the digitizer+screen assembly alone? I'm charged AED400 for a phone that today costs AED650 in the market brand new. I am now forced to get it repaired from a third party for cheaper and void the warranty.
