Phone holders are commonly made from durable materials like plastic, metal, or a combination of both, ensuring strength and long-term reliability. Their primary purpose is to keep the phone stable for activities such as watching videos, video calls, navigation, or hands-free operation. Some designs feature adjustable angles for better ergonomics, anti-slip bases for stability, and compact portability. By improving accessibility, reducing hand strain, and enhancing usability, phone holders have become essential daily accessories for modern smartphone users.
