Hi! I commented buy a Lumia 535 Touch ignoring the problem that they have. I have updated to the latest version team, the magnifying glass off the bar up only in black color, almost all indications that I found online, but still fails ... when I put the pin desblloqueo sometimes have to press 4 time to respond! ... anyone know any other solution for this problem? or if you know if Microsoft is taking action on the matter? And last: will it help install the Windows Phone preview 10?
