I have bought my xperia sp on November 2013. Last week i have seen some dust under the screen. So ive visited sony service station but the guy said me dust problem is not cover in warranty but i will clean it for u. But after couple of days i can clearly see dust under the screen again and in higher volume than before. As i have read in another post that this can be cover in warranty since my phone is in warranty period. And whats the permanent solution for it?
I am a loyal customer of sony.
