Love the idea of genius Go but unfortrunately with the S3 as soon as screen saver kicks in it disables wifi so you will not receive any calls from Genius.
S2 had ability to switch off wifi timeout but S3 has removed that menu option. Wifi/Settings
You can disable wifi timeout using dial codes to get to service menu but it has a couple of drawbacks.
If you reset phone you have to go into service menu and disable timeout again
Also its still seems to time out when phone is idle for more than a few minutes
Any one experienced this
