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 significant factor is the shift toward cross-device standards, replacing the fragmented early mobile era where varied networks required unique file types; with MP4 offering strong support and versatility, 3GPP2 adds no benefit and remains mainly in legacy phone backups, MMS records, voicemail databases, and regulated archives that keep original formats for authenticity.

When we say 3GPP2 prioritizes small file size and reliability over visual quality, we’re describing a deliberate design trade-off shaped by the harsh limits of early mobile tech, where CDMA networks were slow, bandwidth costly, and phones had very little processing power or storage, so the format used aggressive compression, low resolution, and speech-focused audio to ensure clips could be recorded, sent, and played reliably, even though this resulted in pixelation and softness on today’s high-resolution screens.

Reliability was equally important as minimizing file size, so 3GPP2 included mechanisms to stay synchronized despite delays, 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.
