I had the samething but if you have a old stock zvd . Goto system apps and copy the network location app from the zvd system section . Now take that app and paste it in the system of the running rom that has the lag problem . Make sure the app has the permission set . Now go into cwm and clear cache and dalvik cache and reboot back let phone sit for about 5-10 min and then do the *228 thing yes better known as update . :what: this worked for me .
