• Keep the device�s back and charging pad clean and please take a soft cloth and gently wipe any dust away from the pad and device surface before charging.
• Use Samsung-approved charger with suitable input Voltage and Current.
• If you connect the charger with low power to charging pad, the charging speed may slow and the battery may not charge properly.
• Please check the back cover of the your device.
• The device must be placed very closely from the wireless charging pad.
• So some kind of back cover may prevent the wireless charging. In this case, please remove back cover and try to charge again.
