One of the main issues with 3GP files now is audio that doesn’t play, 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 platform alignment, 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.

Saying 3GPP2 puts small size and reliability ahead of image quality reflects a deliberate trade-off made during a period when CDMA networks were slow and unstable, bandwidth was costly, and phones had minimal hardware power, requiring aggressive compression, low frame rates, and speech-centered audio so clips would reliably transfer and play, even if that causes noticeable softness and pixelation today.

Reliability was just as vital as reducing size, leading 3GPP2 to be structured with timing and indexing capable of handling network instability, keeping playback synchronized through rough conditions, making reliable low-quality clips more useful than glitchy high-quality ones, and resulting in a format that seems primitive today yet persists because it remains small, steady, and accessible after many years.
