I've been on the S3 (stock) for a couple of weeks now and have had zero problems until today. While on the LTE network, some apps won't load data from the internet. For example, I can browse the web in Chrome just fine, but if I switch over to check in on Foursquare or get on FB or try to load the Play store, it never loads data. Anyone have this issue/any ideas on what could be causing it/how to fix? To add, I'm grandfathered with unlimited data and my usage for the month is 1.5GB.
