How can I turn my mp3 music on my microsd card into a ringtone?
I just got my new phone which is a samsung reality. I bought a regular micro sd card that can be placed into my phone. I then converted songs from my mac computer into mp3. I then placed the card into my phone and I put the music files into the music folder on the micro sd card. When I look on my phone the songs are there, but they are just in the music area. It will not give me the option to make the music songs into a ringtone on my phone.
1. From the standby screen, press Menu (Figure 1).
2. In the main Menu, press Settings (Figure 2).
3. In the Settings menu, select Phone profiles and press (Figure 3).
4. You will be presented with a list of phone profiles for different situations and environments. The one you’re currently using will be ticked. Highlight the one you want to use (in our example, Normal) and press the Edit button at the bottom of the display (Figure 4).
5. You are taken into the profile settings (Figure 5). At the top of the list you’ll notice three tab icons – these represent (from left to right), ringtone, message alert, and keypad sounds. You can switch between settings for these by tapping one of the tabs.
6. You should be taken first into the ringtone settings list. Should you want to change the Call alert type (from melody to vibration then melody, for instance) tap this option and scroll through the list of options to choose the one you want.
7. To change the Voice call ringtone, tap this option on the screen. You will be taken into a list of phone file folders from which to choose your ringtone (Figure 6). You can tab across to view files stored on a memory card, if you have one installed.
8. Press the Sounds option. You now have the choice of choosing from your Music files, Ringtones that are loaded onto the phone, or My voice clips (clips you have recorded) (Figure 7). You can select from whichever of these folders you want – the setting procedure is the same for each. In our example, we’ll choose from our Music folder to select one of our tunes as the new ringtone.
9. Press the Music option. A list of tracks appears (Figure 8). Tap the one you want in order to highlight it (Figure 9). Press Options, then tap on the Select menu option to install it as your ringtone (Figure 10).
10. You are now taken back to the Normal profile settings, where the Voice call ringtone has changed (Figure 11). To save this change, press Options and then Save (Figure 12). Alternatively, press Back and you will be asked whether you want to Save?. Press Yes.
Hope this may help you.
