Sony Xperia XZs has many problems like heating and crashing of camera apps etc. [img=http://cdn2.expertreviews.co.uk/sites/expertreviews/files/styles/er_main_wide/public/2017/03/sony_xperia_xz_premium_hands-on_reivew.jpg] Hope this will not be the case with XZ PREMIUM WHICH HAS THE NEWLY IMPROVED PREDICTIVE EYE CAPTURE OPTION. "It comes with a new innovation which is the “new Eye motion” camera, where in which you can capture the movements where human eye can’t see properly with much much precise and also in detail."
