C'mon Samsung, quit trying to ship out as many phones as you can and start addressing some of these problems.Guys I'm on the verge of sending phone back because of the lag after browsing, can some of you check your phone and tell me if after browsing or playing games does it take ages for icons and weather application to reappear?
