[Q] Status bar lag. topic

Hello everybody I recently got the Galaxy S3 Neo (I9301I version). The phone is very nice and smooth despite ine thing. The status bar has an annoying lag. Right after a reboot it doesnt lag but few hours after it starts to. If I keep pulling it down quickly for a couple of times it starts moving more smoothly. Is there a way to fix this? It's annoying having a phone which scores about 10'000 on Quadrant and almost 20'000 on Antutu that lags in a a small thing like this.
