Issues with data dropping during mobile hotspot/tethering

I had been having frequent hotspot data dropping issues with my recently acquired Verizon Note 2. I had bought it used with Jelly Beans on it. Switching to LiquidSmooth magically fixed the issues. Verizon had better release a fix for TouchWiz. I seriously doubt Verizon cares at all.
 
Hi, if your USB tethering drops about every 30 minutes and the "Data usage" in Settings always crashes, reset your Android will help.

I have the same issue on Xperia C3 running Android 5.1.1. I try to remove or disable every available apps and updates. Still doesn't work.

Eventually, I reset to factory defaults and everything is okay now. It's the 2nd time happen to me within 6 months. I will install minimize apps and keep track this issue on my post "Android USB Tethering Drops and Data Usage Crashes, try Reset"

Just my two cents.
