I wanted the premium build, but I don't mind what Sammy has to offer either. All is good as of right now.
The issue you're describing - everything works on my network except my Android - has been reported for every Android, iPhone and iPad.
It's a common issue where the addressing tables in your router get screwed up.
Rebooting the phone or going in/out of airplane mode only causes the router to re-attempt. Sometimes it works, but it's not the mobile device at fault - it's the router.
Also, check out "Wifi Analyzer"
Make sure that you're not sharing a channel with other routers in your neighborhood, swipe screen left/right to see.
Never use the default network name on your router, you're bound to get a neighbor doing the same, sooner or later.
If your router has an actual reset button, use that, otherwise, yeah, go for at least a full minute without power.
Hope this helps!
