Hey guys, so after GDR1 my 1520 started lagging on the start screen. I kept thinking of downgrading but really didn't get the time. So yesterday I was fettling with my Start Screen and thought what if it were the folders that were causing the lag. Removed all the folders, and voila! It doesn't lag anymore and has made a world of difference to the experience. So I thought I'd post it here! Hope it helps
Cheers!
