I bought xA1 just 1 month ago,, but from first day of using, my screen (lcd) became dark and after 1 mintue, it came to normal,, now, in this week, i have this problem several times and everyday.. Screen (lcd) become so dark and low in light, then after some minutes it turn to normal... Performance of phone in this dark condition is without any problem, but what is the reason of darkening & low light?
