Yes this is the problem because Sony hasnt provided us with any clear info. Its very clear that its a hardware issue and its also easy to determine if it has it or not. But what i am after is to know on what batch is it safe to buy the Xperia S. I already bought one and sold it because i cannot claim warranty because it was a grey import. I would want to buy again but i want to make sure that it does not have that problem anymore since its really a hassle to exchange it when the problem occurrs. I am located in the Philippines and excahnges here are really a hassle and most Sony reps here are ignorant of the problem.
