Furthermore, even when the User-Agent is corrected, Android users face a secondary hurdle: permission management. Unlike desktop environments where file access and audio playback are handled seamlessly in the background, Android’s security sandbox is more restrictive. For Buster to function, the browser requires permission to record audio or access storage to save the temporary challenge file. Many users report Buster "doing nothing" because the browser failed to prompt for these permissions, or because the permissions were denied by default. The fix here requires navigating to the Android App Settings for the specific browser (e.g., Firefox) and manually enabling "Microphone" and "Storage" permissions. Without these, Buster may successfully locate the audio challenge but fail to process it due to system-level restrictions. Post: Fix for "Buster Captcha Solver for Android"
