When away from home WiFi, WiFi is disabled and phone brightness is increased to 40% when WiFi reconnects goes back to 0% brightness to save battery.
Changes from v1 (credit to orig dev):
-40% should be sufficient to see screen in sun for entering password and manually adjusting brightness, saves battery.
-WiFi isn't disabled so it can reconnect when back home automatically & lowers brightness for inside use.
