Checking handset experience
Operating system, messaging app, carrier behavior, and device settings can change presentation. Keep text, destination links, and images understandable independently.
Putting the guide into practice
Use representative authorized test devices to check crop, text size, playback, contrast, and links. Save screenshots alongside the exact approved media version.

Limits and review decisions
Do not promise identical rendering on every device. Report the tested conditions and retain a useful fallback.
