The Xiaomi Mi 4 comes with a custom Gallery app. It defaults to your camera roll with two shortcuts at the bottom that will take you to album view of your local images and album view of your cloud pictures. You can't change this view, nor can you customize the default folders.
The available features when viewing a single image are pretty standard - set image as wallpaper/contact image, share it, delete it, enter edit mode or just get more info.
Viewing a single image • options
The integrated editor offers various effects, frames, tools (crop, mirror, straighten, rotate, fisheye, doodle) plus light adjustments that let you bring out the shadows or the highlights.
The MIUI music player is a custom app with a well-laid out, easy to navigate interface. It has a huge visualization screen doubling as a Now Playing windows. Below you get four non-customizable tabs - All Songs, Artists, Playlists and Online.
The Online tab is where you pay for the Baidu Music service, which allows you to listen to their huge online track collection. Here you can also find various internet radio stations you can listen for free.
Online music and online radios
The player has cool 3D effects, transitions and transparent elements, especially on the expandable Now Playing section.
Xiaomi's Music app offers customizable equalizers with a few default presets already available for use. You can also try Xiaomi's MiSound enhancer, which comes into play when you use headphones, and especially, a Xiaomi-branded set.
Audio enhancements and equalizers • Editing a song
Finally, you can edit song info and you can also enable automatic song info download in case the ID3 tags are empty. Lyrics can be downloaded, too.
The phone has an FM receiver and supports radio recording. There is a sleep timer as well.
Xiaomi's video player has very basic interface but rich video decoder support. It managed to play everything we threw at it save for WMV files. The AC3 audio codec is supported too. Interestingly, the player won't list MKV files, but it can still play them hassle-free, if you access them from the file manager.
The video player, just like the music player, offers access to a paid video streaming services for movies and TV shows.
Subtitles and pop-up play are not supported by the MIUI's Video app.
The Xiaomi Mi 3 did rather disappointingly in our audio quality test and we were hoping that its Mi 4 successor will fix that. Unfortunately, even though the new flagship did improve some of the scores of its predecessor it still remained a rather mediocre performer.
The performance with an active external amplifier was a mixed bag, combining below-par volume levels with disappointingly high stereo crosstalk and imperfect frequency response. The frequency response is actually a tad better than on the Mi 3 and there's no overly high distortion here, but there are still issues remaining.
It was more of the same when we plugged in a pair of headphones. Stereo crosstalk worsened a bit more, while distortion crept in. Not the best of showings by any stretch of the imagination, but probably good enough for less demanding users.
And here go the results so you can see for yourselves.
