A 3GP file was originally created by the 3rd Generation Partnership Project as a simple mobile video format for early 3G handsets that struggled with tiny storage, weak processors, and short battery life, so it used a lightweight MP4-style structure that favored compact size and dependable playback, bundling timing info with video formats like H.263 or baseline H.264 and audio formats like AMR—an extremely low-bitrate speech codec—causing narrow voices and loss of background sound today.

A common modern frustration with 3GP files is silent audio, caused not by damage but by AMR incompatibility, since players and browsers often omit AMR decoding for workflow reasons and therefore play only the video; editors are even stricter and may refuse AMR completely, so it seems like the audio is missing when the software has deliberately left it out.

3G2, a counterpart to 3GP from CDMA networks, behaves with even less compatibility in modern environments because it uses EVRC, QCELP, or SMV audio that current players and browsers rarely decode, leaving only video until a converter translates the legacy codec into AAC, proving that the missing audio was tied to telecom-era encoding.

3GP and 3G2 are not fully independent formats like AVI versus MKV; they share the same ISO Base Media File Format origins as MP4, meaning their internal boxes for timing, tracks, codecs, and metadata look almost identical, and the main way they differ is through subtle ftyp brand tags like 3gp6 or 3g2b that many programs barely acknowledge.

To put it briefly, 3GP and 3G2 belonged to a previous era of mobile technology where compatibility meant running on early phones, not today’s systems, so silent audio or playback failures arise from legacy codecs, and the straightforward remedy is converting the audio into a supported format while keeping the video as is.
