What should I avoid doing near the camera lens to prevent damage to the Galaxy A04e?

Avoid exposing the camera lens to strong light sources such as direct sunlight, as this may damage the camera image sensor and the damage is irreparable, causing dots or spots to appear in photos. If the device is used with a cracked glass or acrylic body, there is a risk of injury, and you should not use it until it has been repaired at a Samsung Service Center. Also, if dust or foreign materials enter the microphone, speaker, or receiver, the device's sound may quieten or certain features may not work. (Page 6)
