Redmi 3S Prime Build and Design

Xiaomi’s newest handset in India, the Xiaomi Redmi 3S Prime has a good design, just like any other products from them. Usually Xiaomi bring new designs to their every device, but this year Xiaomi seems to be sticking to a single design. The Xiaomi Redmi 3S Prime looks almost similar to the Redmi Note 3. It is not the first time a company using the same design for most of their devices, Apple is an example. Xiaomi Redmi 3S Prime looks like a smaller Redmi Note 3, that is not bad at all and that makes the phone one of the most ergonomic.

The Xiaomi Redmi 3S’s camera and flash lie at the top left of the phone, with the fingerprint sensor resting similarly to the Redmi Note 3. The placing of the fingerprint scanner is to perfectly place your index finger to fall on, without looking. The fingerprint sensor is fast, and makes negligible erros. There are metal trims on the front which makes the display seem pushed inside in comparison with Redmi Note 3.

Just like on Redmi Note 3, the speakers are the back, it tends to muffle the audio when we kept it on a bed or similar surfaces. The design of the Redmi 3s Prime relies on curves to nestle into your hand, and it feels like it belongs there. The design is actually very different from Redmi 1S and Redmi 2. The metallic finish on the back give the Redmi 3S Prime feel more premium. The device is lightweight too, weighing at 144 grams including the 4100 mAh battery. Xiaomi had to reduce the size of the PCB to include the large battery with it.

At this price point the 720p display on this device can’t be criticized. Xiaomi Redmi 3S has a 5 inch display with a resolution of 1280×720 and a pixel density of about 296 ppi. This display has very good brightness, sharpness and viewing angles in this segment. The peak brightness with auto brightness turned off is 610 lux, which is considerably brighter than the Redmi Note 3, and pretty much the same as the LeEco Le 2. Redmi 3S has very vibrant colours, but it is biased towards the cooler side. If you like warmer colours, the MIUI has options to enable reading mode to make colours warmer. You can also use the Warm setting in the Colours & Contrast option. As usual the touch response of this display is top notch.

Redmi 3S has a 13 MP PDAF rear camera with a f/2.0 aperture. Just like Redmi Note 3, images shot under bright conditions are good, but images show noise in poorly lit situations, indoor and night shots, thanks to higher than ideal ISO values. Redmi 3S’s camera is able to focus fast and there is major difference in colours when comparing with Redmi 2. The rear camera can shoot Full HD videos. Like most budget phones, the Redmi 3s isn’t very good for video shooting. The lack of stabilisation is accepted, but it is a bit too apparent, and the audio recording is not good either. The 5 MP front camera is just average for taking selfies with a f/2.2 aperture and 1080p video recording.
