There is a small gap between the phone buttons and body to prevent the buttons from jamming. This is normal and shouldn't be a cause for concern.

• If your phone is not properly handled after being corroded with liquid or grease, the button may become loose.

• The button may also become loose if your phone has been dropped or suffered a physical impact.

If a loose button affects your ability to use your phone normally, back up your data and take your phone and proof of purchase to an authorized Huawei Customer Service Center for assistance.
