After amber update my phone screen does'nt work properly. When I receive a call or a message or when I try to unlock screen I see various color dots on the screen.The pattern is same almost everytime. one out of 20 times I will be able to unlock screen.
I cant take calls .
I am a windows phone developer myself and its sad to see such a thing. Its a major bug.Please let me know if there is any solution.
