I recently got a new Xperia M4 (E2303 I believe). I've been super careful in caring for him.
But out of the blue, I suddenly have a small crack in the top left hand corner of the screen. And yellowing in that area. There also appears to be yellowing in the bottom left hand area, a larger section, around the back and home software keys. There doesn't appear to be any dead pixels but I somehow failed the touchscreen diagnosis test.
There also seems to be a problem with the headphone socket, the headphones in question are new and play nicely with other devices. And the handset in question is barely two months old.
I'm very disappointed with my shiny new Xperia, heartbroken infact, considering that I've looked after it so carefully.
I also did some research online and it seems there is or was a common problem with the Z series and "spontaneous cracking", but i thought I was safe?
Would I have to pay for a repair? Or would a manufacturer warranty cover it? How long would it take? Can I change handsets or get a refund or anything? Would unlocking my bootloader and/or rooting the phone affect any of this?
