If your mobile phone cannot be charged properly using the wireless charging pad, it may be due to a variety of reasons, it is recommended that you try the following actions:
1. Please check whether the back center of the phone is placed in the center of the wireless charging board.
2. When there are inclusions between the mobile phone and the wireless charging board, it may not be able to charge normally.
3. Check the back of the phone. If the protective phone cover used is too thick may hinder wireless charging, it is recommended to remove the phone cover and try to recharge.
4. Please use the original Samsung charger. If you use a non-original charger, you may not be able to charge normally.
5. Connect the phone directly to the wired charger to check whether it can be charged normally.
