On January 5, I bought my new lumia 620. It's beautiful, I love it very much. :grin:But I very very disappoint the response speed of touchscreen.:crying: If I move my finger on the screen, the tiles not move immediately. It will start moving about 0.3 seconds later. If I do this on my old lumia 710, tiles will start moving immediately. The response speed of touchscreen of lumia 710 is much more faster than lumia 620. I have tested this on several other lumia 620 phones, all of them are just the same. I think there is some problem on the firmware of lumia 620. The response speed of touchscreen of lumia 620 shoud be faster than lumia 710, because the hardware of lumia 620 is much more powerful than lumia 710. But in fact, it is much more slower. There are several other lumia 620 fans complained this problem on the Chinese lumia phone forum (Windows Phone). I had wrote a letter to nokia, and hope the firmware updates in the future could solve this problem. I had tested the htc 8s, and the htc 8s didn't had this problem. Any other guys have this problem? Sorry for my poor English.
