when sony will solve this issue, i really hope sony will give some solution. still now sony will concentrate to give software update to new model (highend phones). friends not only the z2,z3, c models. recently my friend mobile got lolipop update in xperia z ultra, after that they got the same problem. Really sony failed the sofware developing side. if it is not true means then y do u still sending the sofware update notification. people are updating the phones, they expecting something new, day to day smartphone having some great things. But still sony does not solve this simple issues. everyone please notedown, our phone is good, durability compare to other phones, Mic also working nice in video and voice recorder. but the software turns to makes this issues. i think sony got blind in some few month to read our post. we have a rights to ask to solve this issue. we don't need to go sevice center, they know the problem. but still they react like this is the first time they seen tis type of problem now itself.
