S8 plus not uodating
I have a Samsung Galaxy S8 Plus. It is model SM-G955U. It is not updating to Android 8.0. My last security update was October 2017. I just got this phone today. I've tried scanning for updates but it says it is up to date. What can I do? I'm still on Android 7.0. There have been 8 updates since the ones I currently have and my phone cannot find the updates through the software update.
