I am a devout Droid user and have never made the "Apple" jump. I have never had a Samsung phone before - let alone a device like this. I have a few minor glitches/questions: Sometimes after ending a call I notice the World Clock is on my screen requesting to add a country's time zone to the phone. Why is this popping up? I assume my screen locks when I hold the phone to my ear during a call... My hand gesture icon is inconsistently displayed and working... Is there a "night time" feature that silences the audible tones/vibration of notification alerts - but still leaves the phone ringer on? I am using SwiftKey for spellcheck-reasons alone. Is there another app or feature I should know of? Is there a way to tap "space" twice to input a period?
