after i got the ota update the gps was working really good and fast now a week later its back to being the same as before it takes forever to lock on and when i do gps test it says im locked on to 3-4 out of the 11 in view. just last week i used the navigation and it got me perfectly to sixflag which is 90miles away from. i haven't rooted my phone ever and i have the j16 build on it
