Does anybody has recommendation how to fix Bluetooth problem with my Samsung 4G, Android 4.1.2 version? The freehand connection lasted a few minutes, then will disconnect. I did trouble shooting by disconnection the phone and reconnection without any improvements. The cell phone is working great and I had no problem before. Zack
Zack, The current firmware for T-Mobile Galaxy S4 is 4.2.2. Go under settings, more, about device and click software update. I have also found that there are some problems if you have a second bluetooth device attached to the car for music and Entune is NOT running. Make sure Entune is launched on your phone...
