Camera and Audio
A 1.3 MP rear camera adorns the back, capturing images adequate for snapshots but lacking in resolution and features compared to later smartphones. With the absence of a selfie camera, the P51 was not designed for the photography and social media-centered use that became prevalent later. Audio features included a loudspeaker and downloadable polyphonic or MP3 ringtones. However, the absence of a 3.5mm headphone jack required users to rely on proprietary connections for audio accessories.
