Also Sony's preinstalled music app is the worst I've ever seen. It cannot create/edit playlists or playback queues. It can only delete playlists, and whenever you do that the app will interrupt music playback for a second. It can only display album cover thumbnails if their resolution is around 80x80 or lower. Thanks to Android it's possible to install alternatives, but a more lightweight system would have been preferrable. It can only charge the battery while switched on. The last time the battery was at 15% when I plugged it in, and the Walkman instantly booted up Android, draining the battery to 7% before it started charging. I do not know what happens if the battery charge isn't enough to boot up the OS and I'm too afraid to try. It's a really neat device and I like using it, but it has so many puzzling quirks.
