The most typical problem encountered with 3GP files today is audio missing entirely, which stems from AMR incompatibility rather than corruption, as current players, browsers, and editing software often exclude AMR decoders, so they play the video but ignore the audio, making it appear lost when it’s merely unsupported.
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 emphasizes tiny file sizes and reliable operation over visual fidelity points to a purposeful engineering compromise made because early CDMA phones had limited memory, slow processors, and unreliable bandwidth, requiring heavy compression, low resolution, and speech-only audio to guarantee recording, sending, and playback, though this now shows as pixelation and detail loss on current high-resolution devices.
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.
