Samsung SYNC SGH-A707
Fixed the low volume problem
Using this code (*#0002*28346#), access the secret volume controls.
Now the Sync volume can be adjusted to be louder than LG-CU500 on earpiece, speakerphone and playing MP3 on speaker. The adjustments on bluetooth earpiece has no effect. However, a wired earpiece can be adjusted to be louder.
Can I hear you now? Yes, loud and clear.
The one thing about this stuff is that when you power cycle, you reset all the levels to default, so 1: you can't screw it up and 2: you have to redo this every time. Good luck.
