Caption usability depends on more than whether a subtitle icon appears. Test a programme with available captions, then check readability, timing and line placement from the normal seat. Include the person who will use them so that the chosen appearance meets their needs.
What matters here
An app may offer subtitles, closed captions or several language tracks, but their availability belongs to the actual programme and feed. System accessibility preferences may not override every player. Test the exact app rather than assuming a setting applies everywhere.
Work through these checks
- Open a programme with a known available caption track.
- Select the desired language or accessibility track.
- Compare text size, contrast and background options where supported.
- Check that the lower lines are not cut off by picture zoom.
Avoid this mistake
Do not promise captions for every programme simply because the device has a caption setting.
