Cause:

The laser engraving content of black phones is light in color, and may accumulate dust and smudges during normal use.

Solution:

• To keep your phone in good condition, use a Huawei protective case that matches your phone.
• If your phone has picked up dirt or dust, wipe it gently with a piece of damp microfiber cloth.
• To remove fingerprint smudges and other oily residues, wipe your phone with a soft piece of cloth dipped in alcohol or brush it with a soft brush dipped in hand soap, then dry it with a paper towel.
