The primary reason Buster fails on Android lies in the architectural limitations of mobile browsers, specifically regarding the User-Agent string. On desktop browsers, Buster operates by detecting when a reCAPTCHA challenge appears and automatically clicking the audio button, downloading the audio clip, transcribing it, and entering the answer. However, Google’s reCAPTCHA infrastructure treats mobile devices differently. When a user accesses a site via an Android browser, the request headers identify the device as mobile. Historically, Google has disabled or hidden the audio challenge option for mobile User-Agents, preferring to serve the image selection grid which is more intuitive on touchscreens.

Users attempting to "fix" Buster on unsupported browsers will fail simply because the environment does not support the tool’s code execution.
