My Samsung note 4 at&amp;t won't update to nougat. This new verion for note 5 was released in April-2017 and I'm still not able to update it. When I try to check the updates it says 'Your software is up to date' It is so frustrating that my other friends that has note 5 with the newer version of android. Note: I do not live in the US. I've read on the internet that to get an update I need to be connected to the At&amp;t servers and in order to do that I have to be in the US. Please help. Screenshot is attached.
