Samsung s3S5 can play lossless music. First, understand what lossless music is. Music file playback formats can be divided into lossy compression and lossless compression. However, because there will be data loss in the process of audio digitization, it is actually impossible to achieve real lossless now. Therefore, to listen to lossless music, you need to download the music player or the player that comes with your mobile phone, but if you want to achieve lossless level, you need the mobile phone hardware with professional audio decoding chips and professional headphones to listen to professional music.
