The biggest problem people run into with 3GP files now is sound that’s missing, usually because the AMR codec isn’t supported by newer players or editors, causing them to decode only the video while ignoring the audio track, which makes it look like the sound has disappeared when it’s actually being blocked.

Another relevant factor is the trend toward unified media formats across all platforms, unlike early mobile ecosystems that were split across many incompatible types; MP4 became dominant for its wide support and flexibility, so 3GPP2 now persists mostly in old backups, MMS archives, voicemail systems, and compliance-focused records that retain originals to ensure accuracy.

Saying 3GPP2 puts small size and reliability ahead of image quality reflects an intentional engineering approach 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 equally important as minimizing file size, so 3GPP2 included mechanisms to stay synchronized despite choppy networks, ensuring playback continued even when conditions were rough, making a functioning low-quality video far more valuable than a failing high-quality one, which is why the format—although crude by modern standards—still appears in archives due to its durability and readability.
