I have a Lumia 920 and i updated to cyan. Do you think that the performance will be better with gdr1 or should i keep it just with cyan.
I updated to Cyan I was happy with the overall performance, except IE. It was crashing too often. So I decided to take the DP Update 1 but the battery performance was awful..so awful I decided to revert to the 'stock' WP8.1 and Cyan for better stability.
