Same here too, and it is driving me nuts. I had a Note 5 64GB no issue, traded in for Note 7 at the end of August, and the Note 7 had no issue (HAHA), then had to get a Note 5 32GB because I fly every week mid-October. Since I got my 2nd Note 5 I am having the same issue since October purchase:
1. Screen Rotate stops working - Google Maps, Photos, etc.
2. Auto Brightness stops working
3. Data off and on, very erratic - which causes maps to report no data
4. Texting app starts giving me error messages
5. WiFi Pop ups are turned off, but soon as all the above starts up, WiFi sites start popping up. Especially annoying when boarding a flight and and I cannot show my boarding pass because the Airport WiFi keeps asking me if I want to sign in.
and I am sure there is more that I have not discovered.
The fix, restart. Works for a few hours or even a couple of days, then fails again. What I have done, Hard Reset in December. Did not fix it, same issue after a couple of hours. Verizon replaced the phone 2 weeks ago, same issue after a couple of hours. (The phone I had received had no updates since August, 2016 hoping that would would fix it, nope) Verizon then called Samsung, had a tech log into my phone, added a firmware update. It fixed it for 5 days, then I am back to frustration again.
My belief, a firmware change last summer in August that messed up the Note 5.
