I have put my money in "Dust bin" by buying this phone. This is ultra slow. Many times it simply DO NOT respond to the touch screen input. Takes 3 to 7 seconds to open up SMS menu or call log menu.
Worst of all is a software bug.
If you try to forward the SMS to someone, then you get Add Recepient screen where you select the Recepient. after clicking DONE button, the same screen keep appearing again and again. All you can do is shut down the messenger application or restart your phone. You will find that the SMS you tried to forward is lying in Drafts" from there you can send.This is not expected from SONY. This phone have laid down reputation of SONY. I have lost my money.
