initially I was not a fan of the xperia Z up until you released the 4.2.2 update. Amazing. So could it convinced me to purchase another xperia Z device the xperia tablet Z. Again very happy. So far so good. I was contemplating getting the Z ultra or maybe the z1 until a strange thing happened. The flap on the headphone jack no longer sits flush with the device after use. In fact it slowly slides up exposing the jack. Is this a design fault as surely these flaps, given that they part of the waterproofing design, should be up to daily use (especially the head phone jack).
