Xiaomi Redmi S2 Review

Primary camera photo and video samples

The rear camera department of Xiaomi Redmi S2 includes two shooters. The main one is equipped with a 12MP Sony IMX486 Exmor RS sensor. The same one powers the main camera of the Doogee BL9000. This image sensor has a 1/2.9-inch size and a 1.25-micron pixel microarchitecture. On the Redmi S2, it is paired with a 5-element lens with an f/2.2 aperture. This camera is aided by a single-LED flash and PDAF. It takes photos with a resolution of 4000 x 3000 pixels and shoots 1080p videos at 30 fps. It can also take slow-motion and time-lapse videos. The second rear camera employs a 5MP Samsung S5K5E8 sensor with a 1.12 μm pixel size and a 1/5" optical format. This sensor is largely used by Xiaomi for the front cameras on the Mi A1, Mi 5X, Mi Max 2, Redmi Note 4X, Redmi Note 4 16GB, Redmi Pro Standard Edition. Meizu m3 Note uses it for its secondary rear camera. On the Redmi S2, it works only in tandem with the main camera when you shoot in Portrait mode in order to create a depth effect.

Secondary camera photo samples

The front-facing camera is equipped with a 16MP Samsung S5K3P8SP sensor. The same one is used for the selfie shooter of the Smartisan Nut Pro 2. The sensor is very new. It has a 1/3.1" size and a 1.0 μm pixel size. On the Redmi S2, it is coupled with an f/2.0 lens. The camera shoots photos with a resolution of 4608 x 3456 pixels and 1080p videos at 30 fps. It is aided by a single LED flash and supports face unlock which is very fast.

Camera app

The Camera app on Redmi S2 is typical for MIUI 9.5. The main screen contains a circular shutter button at the bottom's centre. To its left, there's a shortcut to the list of photos and videos and to its right, there's the camera switch. Above those buttons, you will see the list of shooting modes - Photo, Portrait, Video, Short Video, Square, Panorama, Manual. No zoom is available. The top of the screen is occupied by the flash and HDR options, filters icon and a hamburger menu that opens additional options depending on the type of shooting modes and a shortcut to the camera settings. One of the most interesting features here is the Portrait mode, which manages to create a good for a cheap smartphone bokeh effect when shooting portraits. It is the AI technology that creates a more accurate map of the face and helps to achieve a natural-looking portrait. The Manual mode contains only two options - for the white balance and for the ISO, which can reach up to 3200.
The additional camera options when you're in the default Photo mode you can switch on/off the Timer, chose the type of Tilt-Shift, Straighten, choose the Scene, HHT, and choose the type of Beautification. When you're in Video mode, you can choose from Time-lapse and Slow-motion video shooting. The camera settings also differ depending on which mode is on. From the Photo mode, you get access to the photo shooting settings such as gridline, time stamp, mirror front camera, camera frame, picture quality, exposure, saturation, contrast, and sharpness settings. From the video shooting mode, you get access to video shooting settings such as EIS, video quality, time lapse interval, etc. There are settings that are common for all modes such as location info, camera sounds, anti-binding, auto exposure, fingerprint shutter, volume buttons function.
The main screen of the front camera contains the same shortcut to the list of photos and videos, shutter button and camera switch. It lists the same shooting modes but not all are supported - the Portrait, Panorama and Manual modes switch to the rear camera when selected. Above the shooting modes, there's an icon for beautification effects. On the top of the main screen, you get the flash and HDR options, the hamburger menu with additional options and camera settings and the Depth effect button - similar to the Portrait mode. This is when the second 5MP rear camera comes into play. This mode also offers beautification effects but this time to the standard degrees of a pre-set combination of beautification effects you can also manually adjust the degree of each beautification effect - eyes enlargement, cheeks slendering, skin tone correction, etc. For the Photo shooting mode, the additional options include a timer and age & gender info. There are no additional options for the other shooting modes. The photo and video settings are the same as the ones for the rear cameras.
Photo and video editing happen only via MIUI's Gallery app as this is the original Chinese ROM. The photo editing options include adding beautification effects, cropping, adding filters, stickers, text, mosaic effect, or doodling. You can also adjust the brightness, sharpness, contrast, saturation, vignette. There's an Erase option as well for objects and lines. Video editing options include frame trimming, adding text, filters, or audio. The advanced editing options lead you to a page to download a special app in Chinese.
