Preparing Your Samsung Galaxy A21 for Resale

Cleaning Steps
Power off your device before cleaning. Use a microfiber cloth slightly dampened with a mixture of water and isopropyl alcohol to gently wipe the screen and body. Avoid excessive moisture and do not spray directly onto the device. Use cotton swabs and compressed air to clean around ports and speaker grills. A soft brush can help remove dust from crevices.
