I've had my S4 for about a week now and its been working flawlessly. Today though I noticed some issues. While connected to 4G network (I'm with Verizon), certain things will not load on apps. Mostly images. For example, when using facebook or instagram I can see text and links pop up but if there is an imagine some of them will not load. Its very annoying. It does not do this while connected to wifi. Any suggestions?
