Walkman music player
The W300i also functions as a Walkman music player. The W300i can read both MP3 and MP4 tracks, and software which comes with the mobile phone (Disc2Phone) can convert other file types such as WMA, and although album artwork is not viewable, the W300i will read track details (via id3v1 tagging): artist, album, song name and sort them for easy access.
White Screen Of Death – According to many owners, the screen has a tendency to freeze and/or go white.
Flimsy parts – The top of the phone is also known to have some flex issues.
Battery cover – It has been stated in some official and unofficial reviews that the battery cover is very difficult to open. The User's Manual shows that you only have to push out the battery cover, yet this is very difficult to accomplish. An easy fix for this is to put an eraser on the cover and use it to slide the cover open. Furthermore, continued opening and closing of the battery cover causes it to lose its ability to stay on the phone, and instead needs to be taped or glued on. However, it's only stated that SOME of the phones have this particular issue, not all of the W300i series have this problem. Also it's noted that some of the batteries that are inserted into the phone swell up within a month or so.
