Hi I am using Samsung Galaxy S2. This is my first switch to android from iPhone 3 to 4S. I need a reminder which will keep on alerting until I switch it off i.e. until a user action is taken. Can I do this in my phone ? Also , when I get a new email , I only get a sound alert. My phones light doesn't turn on and show a new email. Just sound... Please help and advice! Many thanks!
