A common problem with 3GP files today is silent sound, and it usually comes from AMR codec incompatibility, as many playback tools don’t include AMR decoders, so they show the video but drop the audio entirely, giving the impression it’s gone when it’s intentionally unsupported.

Another important factor is cross-platform consistency across devices, since early mobile systems were fragmented and required different formats for different networks, whereas modern media is expected to work smoothly on phones, computers, browsers, and apps, making MP4 the preferred choice due to wide support and flexibility, leaving 3GPP2 mostly in legacy backups, MMS archives, voicemail systems, and regulated records where old formats are kept for authenticity rather than relevance.
When we explain that 3GPP2 values small size and consistent playback more than picture quality, we’re referring to a purposeful constraint created for an era of slow CDMA networks and extremely limited phone hardware, which forced the use of aggressive compression, low-resolution video, and simple speech-based audio so clips could reliably transfer and play, even if they appear soft and pixelated on modern screens.
Reliability was just as vital as reducing size, leading 3GPP2 to be structured with timing and indexing capable of handling incomplete transfers, 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.
