The redesigned MIUI 8 gallery app we saw on the Redmi 3S is back on the Redmi 4 Prime. It defaults to your camera roll, but it also supports different albums. Xiaomi's new app now automatically stacks your photos in Camera, Video, People, Screenshots, and Panoramas albums. The People sorting, once chosen, sorts all of your photos by people's faces.
The MIUI 8 gallery seems to have borrowed some of the iOS Photos looks, but nevertheless, it's better than before, and we appreciate the new looks and features.
The new integrated editor powered by Camera 360 offers various filters, crop options, enhancements (sharpen, contrast, brightness, saturation, vignette), and doodles. Oddly, this image editing app is less capable than the one supplied with the MIUI v7.
For video playback you can simply open the files from within the gallery. The video player interface is very basic; subtitles and pop-up play are not supported. You do get a separate brightness slider just for video playback.
There is also a new video editor with MIUI 8. It supports trimming, filters, and adding text, and audio tracks.
The MIUI music player is a custom app with a well laid out, easy to navigate interface. The player has cool effects, transitions, and transparent elements, in particular on the expandable Now Playing section. Lyrics are supported, too.
Xiaomi Redmi 4 Prime offers customizable equalizers within the phone's Settings menu - there are 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 headset.
An FM radio app is also available. The Redmi 3S requires a headset to use as an antenna. FM recording is also available.
The Xiaomi Redmi 4 demonstrated perfectly clean output when hooked up to an active external amplifier. Its loudness was very high too, adding up to one of the finer showing out there.
Better yet, there was next to no degradation when you plug in a pair of headphones. Outside of a moderate stereo crosstalk hike, the output remained just as good. Loudness was unchanged too, making this one of the better outputs we've seen, and much more so in the entry level.
