Xiaomi Redmi Note 4 (S625) review: Take Note!
Take Note!
Gallery
The Xiaomi Redmi Note 4 comes with a custom Gallery app that shows the camera row by default, but the second tab includes all images and videos on the phone. You can set up a photo backup with your Mi Cloud account.
The Gallery app remains unchanged
The integrated editor offers various effects, filters, and enhancements, plus fun stuff like stickers and doodling.

Music player
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, especially on the expandable Now Playing section. Lyrics are supported, too.
The music player cares about streaming as much as your offline library
Xiaomi Redmi Note 4 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.
FM radio
The FM radio requires a headset to be connected and can play sound either through it or through the loudspeaker. The app can record audio and there's a sleep timer.

Video player
Videos are launched from the gallery. There's no subtitle support here, but DLNA is on board.
The simple video player
A surprisingly powerful video editor hides here - it can trim videos and add filters, text labels, or even a soundtrack (from a predefined library of tracks or your music library).

Audio output is excellently clean, not very loud
The Xiaomi Redmi Note 4 aced the active external amplifier part of our test. The smartphone posted perfect scores for clarity, and its volume was well above average.
Unfortunately loudness dropped to below average when headphones came into play. The good news is that was the only damage that applying resistance to the line-out caused with the clarity readings remained just as good. Stereo crosstalk did increase, but it’s not nearly as pronounced as with most of the Redmi Note 4 peers.
