Well i did visit the service center and told them this issue which I started to experience after receiving an update 2 weeks ago. So now the only solution they have is that they will install some older version of android which I had before getting an update 2 weeks ago. And then i will to wait for the next update to come till then I should not update my device.
Rediculous, what's the point of spending 60k on an gaming device when you can't play games on the device.
Very dissappointed.
