I have had my Note 4 since the day that it came out. Just recently (since I would say last Thursday) I have begun to have a new and very annoying problem: About 5-10 mins after I begin using Maps with GPS while I travel, the phone restarts. It will continue to do this at 5-10 min intervals while I use it. Over the weekend, left it on all weekend with no maps or GPS running and never restarted once. I even uninstalled/reinstalled maps updates. I cleared the cache and data for that app. It still does it. Yesterday, I noticed that my Sprint Zone won't allow me to sign in and won't show my data usage, etc like it did a few days ago. It just says data usage from Dec 31 to Dec 31. Please someone help me figure this out cos I want to love this phone and this is making it very hard to.
