Oppo R11 review
The gallery
The Gallery app is fairly simple. It defaults to showing your camera roll sorted by date (we miss the option to change the thumbnail size). Alternatively, you can browse images by folder, including a special "Recently deleted" folder, which will save accidentally deleted photos. Remember that you can encrypt files, but there's no way to do it directly from the gallery.
An iOS-like gallery • Browsing by folders is the only option • Viewing an image • Editing a photo
The app does offer a feature to quickly build a collage out of several selected photos. You can also edit individual photos with the usual crop and filter tools, and doodle free-hand too. Slightly more advanced features can blur part of the image (to simulate shallow depth of field), or you can pixelate areas to censor a part of the image or just for artistic effect.
Music player with Dirac Real HD Sound
The ColorOS music player (like the gallery) has a clear iOS aesthetic and is fairly simple in operation. You can browse the local music library by track, artist or album and that's about it. You can favorite songs to make them easier to find. Lyrics can be displayed, but they must be embedded into the file itself; the player will not fetch them from the Internet.

The one more advanced setting is Dirac's Real HD Sound. It's an equalizer with multiple presets and three sliders for manual tuning - Bass, Baritone and Treble. This works with headphones only, as Dirac Power Sound powers the loudspeaker.

There's no FM radio available on the R11.
Audio output quality is good
The Oppo R11 did a great job in the first part of our audio test. The smartphone showed perfect audio accuracy with an active external amplifier and delivered nicely high volume to go with it.
Unfortunately, things aren’t as great when you plug in a pair of headphones. Volume drops to only average, while stereo quality and frequency response take moderate hits. Some intermodulation distortion creeps in as well so the performance is hardly perfect. It’s still decent, but audiophiles might end up less than perfectly happy with this one.
