If you are using Galaxy S3 and looking for a new way to wake up in the morning other than the regular Alarm clock, you just need to activate the Briefing option in the Alarm type setting.
The Briefing wakes you up by reading the latest headlines, the current time, the weather situation, and your appointments for today if there is any.
The Briefing actually briefs you in the morning with some useful information
To activate this Feature:
1. Open Clock App
2. Navigate to Alarm
3. Change the Alarm Type to Briefing
