US region facial verification test

I am conducting a performance and usability check on an English website that supports facial recognition. I need a real user residing in the United States to assist in completing a full login verification process and submit a brief report after use.

Test Requirements:
• Devices: Please complete the verification process using both mobile browser and computer browser to compare the performance on both ends.
• Network: The entire process must use the local 4G/5G mobile network without switching to Wi-Fi.
• Focus Points:
1. Whether facial recognition can be successfully completed in one go.
2. Whether there are any lag, delay, or blank screen issues during page loading or interaction.
3. Whether the speed of camera activation by the browser, picture quality, and shooting process are normal.

Delivery content
1. A written feedback (about 3-5 lines) should be provided, detailing the experience for each of the above three items.
2. If any issues arise, please attach a screen recording or screenshots, and briefly describe the triggering steps and the occurrence time point.
3. The model of the device used for testing, the operating system version and the browser version.

The entire process is expected to be completed in about 10 minutes. Thank you for your assistance. We look forward to receiving the first-hand and genuine experience!
