Install Oreo if You're Dealing with Nougat Problems
If your Android Nougat issues go beyond problems with your device's battery life or UI speed, you'll probably want to give Android 8.0 Oreo a shot.
The Android Oreo change log that appears in your OTA prompt won't talk about bug fixes for lingering Nougat problems. It focuses on the new features. That said, there's a chance the Android Oreo update will squash the problems you're facing on Nougat.
In the past, we've seen Android updates iron out issues that aren't listed on the change log. For instance, Android Oreo could fix busted Wi-Fi, GPS, or Bluetooth connectivity. It could also fix random reboot issues or sound problems.
There's no guarantee Android Oreo will fix your Nougat problem(s) but it's worth a try if you can't find a manual fix.
