I've had my phone for a little over a year, and in the past few months I haven't been able to use YouTube, Snapchat, Netflix, and a few other apps on my mobile 3g/4g data, but I run other apps just fine. I tried uninstalling apps, clearing the cache and data of the apps, yet nothing. All these apps function as they're supposed to while on WiFi. Not rooted, and havent gone near my data limit every month. Any suggestions?
