I buy my z3compact last Feb 2015.and after almost a year problem happens.i did bring it to Sony service center here in Manila,they said it's just a software update but still problem still there.when I bring it back to service center they said battery problem need change,so they change the battery again problem still there now service center said it's the board, I need to pay more than 50 percent of the original price when I buy it,now it's working but start up sound is not working!I'm so disappointed with Sony Xperia I always use Sony as my my mobile phones ever since I first use mobile phones but now I think I'm not going to buy Sony phones anymore
