One of the main issues with 3GP files now is silence during playback, mostly due to modern players and editors lacking AMR support, causing them to load the video but reject the audio without notice, making it seem like the file has no sound even though the codec is just not accepted.

Another crucial factor involves modern standardization, contrasting with early mobile fragmentation where different networks needed different formats; MP4 took over because it works everywhere and handles many quality levels, so 3GPP2 survives mainly in legacy data like old phone backups, MMS collections, voicemail systems, and regulated archives that preserve original files for historical correctness.

Noting that 3GPP2 focuses on compact files and stable performance rather than sharp visuals highlights an intentional balancing act shaped by early mobile constraints—weak processors, tiny storage, and slow CDMA networks—which pushed developers to use strong compression, low-res video, and minimal audio detail to keep transfers stable, resulting in the softer and more pixelated look we notice on modern screens.

Reliability mattered just as much as size, so 3GPP2 included timing and indexing designed to survive partial transfers, allowing playback to stay synchronized even under poor conditions, meaning a low-quality video that ran smoothly was better than a high-quality one that stalled, leaving us with a format that looks basic today but persists in archives because it remains stable, lightweight, and accessible decades later.
