I have Enclosed the Samsung Galaxy S S2 S3 "Good Morning" Alarm,
(Listen to it to see if this is the Alarm Sound you want).
In Your Clock, [I use Alarm Clock Xtreme ~
https://play.google.com/store/apps/details?id=com.alarmclock.xtreme ~
(If I had an S3, I'd use their Alarm)...
If your Phone is not Rooted, then Change the Sound Type
from "RingTone" to "Music". Then Choose "Select Music" ~
{Then Select either "Choose Music Track" or "My Files" or
"Root Explorer" or "Google Music", or other},
and Navigate to where "Good_Morning.ogg" is Located, {I suggest "\RingTones"}.
Set the Alarm for about 1 mnute away,
so that you can Test to see if this is the Sound you want.
I Converted "Good_Morning.ogg" to "Good_Morning.mp3",
and Included both Files just so that you can
Test the Sound on your PC to see if this is the Sound you want.
(You should be able to use the "Good_Morning.ogg" on Your Cell Phone).
{if not then use the "Good_Morning.mp3", and toss the other}.
If your Cell Phone is Rooted, Store the "Good_Morning.ogg" in the
"/system/media/audio/alarms" Folder, then you won't have to Change the Sound Type,
(and you can Instantly Hear the Preview of the Sound).
If your Cell Phone is Not Rooted, store the File in some place like "\RingTones".
{You won't have Access to the "/system/media/audio/alarms" Folder}.
If you'd like to know how to Acquire this File yourself...
If you have an Older Cell Phone, like a Samsung Galaxy S Fascinate,
then you can Use "Root Explorer",
{Acquire From Google PlayStore or Click on the Link Below,
https://play.google.com/store/apps/details?id=com.speedsoftware.rootexplorer}
to get the file from "/system/media/audio/alarms/Good_Morning.ogg".
Email Yourself this File if you have WiFi, or if not Connect to a
Computer and Copy it onto the Computer. Then connect the New Cell Phone
and Paste this file to some location, (like "\RingTones").
