I'm having GPS issues after completing the Nougat update, this morning, on my Note 5.
My location now wanders and will lock in properly for a short amount of time, then wander off again. I live in a small town, so there are no issues of building interference, nor have I had a problem prior to the update. I have switched to GPS only and to GPS, Wifi, and mobile networks. I have the same issue with either setting.
I did the reset, but it's still not right. For anyone that may be worried about losing anything during the reset, you won't.
I'm currently approximately 2 blocks off. It's very sporadic. Sometime it's right on, usually with a bit of a delay, and other times it just stays a block or two off the actual location. It's been mostly off, though.
