This is very similar to my problem...except mine ONLY happens with wifi. I can open up the browser and either the website will just not load, or it will partially load and then stop. However, i have noticed that with mine, the little arrows (indicate data transmission) that are located inside the wifi icon (top of the screen) stop working and the wifi turns solid blue. When the little arrows come back, the page starts loading again. This is NOT a problem that is strictly dedicated to my home network either. It happens on any wifi network, and i have replaced my router 3 times and the phone twice. As soon as i turn off wifi and connect via 4g, everything works great.
This has been frustrating me for a long time, so I'm finally giving up on the Maxx and switching to other "iSide"
