Folks, if you're FED-UP with the childish, moronic and simply idiotic tones on your "Notification" section of your contacts, then this simple solution is for you for your Galaxy S4 where NO SOFTWARE IS REQUIRED: 1) Press the "My Files" on your device's screen and if you don't have one, simply summon one from the apps/widget part of your smartphone. 2) From this screen, press the "All Files" button. 3) Inside, you'll see a "Device Storage" item on the screen. Press this button. 4) You'll see several files on this screen INCLUDING the "NOTIFICATION" file here. Click here. 5) Of course, it's BLANK BUT here, you can MOVE YOUR FAVORITE SMS RINGTONES HERE and when you return to your contacts screen where you assign your notification tones, you'll see your favorite tones ARE THERE...you're VERY WELCOME 6) ALSO, IF you have a memory card installed, you can transfer the ENTIRE "NOTIFICATION" file to your SD Card (MIN: 16GB-MAX: 64GB) to save space on your device's main memory which will run out quicker without the card.
