Sir, I brought a new lumia 530, during the festival season of august last year 2014. It was working fine till 2 months, after wards it started showing sign's of problems such as 1. The wake up button not working 2. some times the touch don't work properly 3. if we launch any application then it will automatically hit back to the home page 4. uc browser, whatsapp not working 5. Problem with the head set slot as some times it will go mute by itself I have given the mobile to the care center more than 4 times, but every time they will say that its the problem with software and they change then also it will be the same after a few days. Literally i'm so fed up by formatting the mobile when ever these problems shows up again and again. so please kindly guide me saying what i should do get these problems corrected.
