Camera lag issues
I don't know if it is very common or not but I have been facing a lot of camera lag. It takes some time whenever I open the camera app although photos are clicked without lag.
Apart from that, whenever I have to share a photo through WhatsApp and go to camera to click the picture, the lag seems much higher and a few times phone hanged and restarted too.
Is it an issue with WhatsApp or maybe after the kitkat update the Camera performance is still not upto mark.
