I try to navigate to a site in my Pantech Burst's default browser and there is about a 2 minute delay before it even tries. It then continues at normal 4g LE speeds after that initial time. If I don't use the phone for a good while (2+ hours), the delay comes back. If I use an app like google maps, the internet is immediately responsive, as it should be. So this makes me think that it is this default browser. Suggestions?
