- Verify that the device, charger, and USB cable have no physical or liquid damage.
- Check the USB connections for corrosion and bent pins.
- The USB cable should be secured firmly in the charging port with very little mobility. If your device detects a poor USB connection, an error will be displayed.
- Inspect the device, charger, and USB cable for dust or other foreign materials.
- If you are using a wireless charger, make sure your phone is compatible with wireless charging.

Reboot the device.
Press and hold the Side button and Volume down button until you see the Samsung logo on the screen.

Charge the device.
Charge your device using a Samsung travel charger for at least 1 hour. The battery charging indicator may take up to 10 minutes to appear on the device's screen if the battery is completely depleted.

Test the device with another charger.
If possible, test to see if your device works with an alternate Samsung charger.
5
Power on the device.
Disconnect the device from the charger, and then attempt to turn it on by pressing and holding the Power button for 15-20 seconds.
If the device turned on, then the device needed to be charged. Turn off the device and reconnect it to the factory travel charger until it is fully charged.

2
Verify the charger.
Samsung recommends that you use the travel adapter that came with your device. If you need to use the PC as a charger, we recommend that you power off your phone or tablet, so it will charge faster.
3
Verify the PC USB port.
If the PC has an available USB 3.0 port, often marked in blue, then faster charging may be available. Try using this port when charging your device.
Some PCs may also have a designated charging port intended to provice higher power output. Check your PC's manual for details.
Important
DeX accessories only support high-speed chargers. DeX mode or Screen Mirroring mode will not launch when using regular chargers with less than 9V/1.67A output. Battery packs are not compatible with DeX.
1
Check the physical connections.
Check the DeX accessory's physical wire connections and make sure that all connections are securely plugged in. Inspect the wires and connectors for damage, and replace any damaged wires.
2
Check the power source.
Unplug the charger from the DeX Station or DeX Pad, and plug it in directly to the phone.
- If your phone is in Maximum power saving mode, it cannot launch DeX mode.
- If the phone is charging slowly, the charger is probably incompatible with DeX. Switch to a high-speed charger with an output of more than 9V/1.67A.
- If the phone is not charging at all, the charger may be defective. Replace the charger with a compatible high-speed charger.
3
Restart your phone.
- Remove your phone from the DeX Station or DeX pad, and restart it using either the Power button or the Power icon in the Quick settings panel.
- Reconnect your phone to the DeX Station or DeX pad.
