If your WiFi doesn't work, give the phone a chance to settle. It took me about 3 hours and it drained the battery very fast. Now that everything is settled, works as normal. Overall everything looks great.
I still had issues with wifi and Bluetooth so the only way to resolve it was to factory reset the phone. I didn't like to do that but I am a nerd and I like to test new software. Now everything works well and the battery does not drain as quick with moderate use. There is an issue with restore from backup (cloud) for the apps not everything else. It starts restoring the app and then force closes before it does, hence not restoring anything.
