Samsung Gear S3 Frontier Troubleshooting

The device does not respond and will not turn on.

Hold the home/power button (the lower button of the two buttons on the right side of the device) until the device turns on.

Ensure that the charging cord is not broken or corroded. If the charger is damaged, try an alternative compatible charger. Then, try to power on the device while it is charging.

Check to make sure battery and all components were properly connected during reassembly.

Follow the battery replacement guide.

Device is turning on but screen is damaged. Follow the front screen assembly replacement guide.

If other options did not solve the issue, the motherboard may be damaged. Follow the motherboard replacement guide.

Battery drains faster than expected.

You should not leave too many applications open in the background, especially the Music and GPS apps, which require the most battery power. To close applications:

1. Start on the "Apps" screen and select "Recent apps."

2. Choose an app and then tap "Close" to end that singular app, or choose "CLOSE ALL" to end all applications.

The power saving mode lengthens the battery life of your device, but forfeits functionality to most applications.

1. Start at the home screen.

2. Hold the bottom physical button and choose the "power saver mode."

Set the device at a lower brightness. To lower the brightness:

1. Start at the home screen and tap the "Brightness" icon.

2. Rotate the bezel to reach the desired brightness.

If all other solutions did not solve the issue, consider replacing the battery with our battery replacement guide.

While trying to pair the device to a phone, the device will not fully connect.

Make sure the smartphone and smartwatch are powered on. Verify that you have downloaded the Samsung Gear App on your smartphone and that the Bluetooth for both devices is on.

1. Open the app and choose the “Gear S3 Frontier/Classic."

2. Match the passkey and tap "OK" on both devices.

3. Continue through pages to set up your account and until device activation is complete.

The connection is not being sustained by both devices, resulting in frequent drop offs in the watch’s functionality. Turn off the Bluetooth connection on the smartwatch and restart it.

The watch may not have enough battery life to complete this action. Charge the watch with the compatible Samsung adapter that came with your device.

Device Can’t Send or Receive SMS Messages.

On the paired phone, navigate to your Bluetooth settings. Disconnect and remove your device from the phone. Pair your device to your phone.

Navigate to your phone’s app settings. Select the Gear Manager app. Clear cache/data and start the app again.

Look at your your carrier's coverage map to determine if you have cellular data/service in that location.
