Ever noticed the CQATest app suddenly appear on your Android device and wondered what it does? The CQATest app stands for "Certified Quality Auditor Test" and is primarily used by manufacturers—especially Motorola and Lenovo—for diagnostic testing and quality assurance. It runs quietly in the background, ensuring your hardware and software meet performance standards. While not harmful, it isn’t meant for public use, and its unexpected appearance may indicate a system glitch. If the CQATest app is affecting your device’s performance, a factory reset or contacting customer support may be your best solution.
