Wher evan I find / download the beta ?
You can't find the beta on any website.It will appear as a banner in your Samsung Members app.The show-up time depends on your phone model and your country.
Baran is correct. I would add that the beta is full as of over a month ago when it launched, so you can't get in anyway. Just wait, Samsung is already rolling out the full version to Germany anyway. We shouldn't be far behind.
Bro u can download update.zip for your phone if u want it so bad search for it on xda
