At the end of March, Xiaomi introduced the Redmi K50 series duo with a new design, powerful hardware, besides this duo, there is another version also launched by Xiaomi, Redmi K40S. This is basically a slightly upgraded version of the Redmi K40 launched last year, but has the design of the K50 series.
The price in the Chinese market of this device is from 6.5 million VND, which is quite attractive for a smartphone equipped with Snapdragon 870 chip. However, in Vietnam market, Redmi K40S is being sold as a portable product at a low price. about 7.9 million VND. At this price, this is indeed not an attractive choice in the price range of 8 million VND.

Redmi K40S has the typical packaging of the Redmi smartphone series, the version we have in this article is the black version, the device also has gray white, blue and blue colors.

Accessories included with the device: fast charger, USB-C charging cable and silicone case

The back of the Redmi K40S is finished from glossy glass with concentric light textures. The design of the camera cluster is almost identical to that of the Redmi K50

The camera cluster includes 3 lenses: 48MP wide angle with OIS support, 8MP super wide angle and 2MP macro. In fact, this main camera cluster is considered by many Chinese reviewers as not as beautiful as last year’s K40 series, looking a bit rough and not aesthetically pleasing.

Redmi K40 is equipped with a 6.67-inch screen using AMOLED panels with FHD + resolution, protected by Gorilla Glass 5 similar to the screen on K40

This monitor has a 120Hz refresh rate and can be customized between 60Hz – 120Hz

Despite using AMOLED panels, most Redmi smartphones have a fingerprint sensor on the side, integrated with the power button

The side of the machine, unfortunately, does not have a 3.5mm headphone jack

Redmi K40S is powered by the same Snapdragon 870 chip as last year’s Redm K40, ie in terms of performance unchanged. The device also has 6/8/12GB RAM memory and 128/256GB storage memory. The battery has a capacity of 4500mAh and fast charging upgrade to 67W

Because it is a portable version, Redmi K40S does not support Vietnamese. The device has Google services available, but users need to activate it in the application settings and then update these services to be able to use it normally.
As mentioned, Redmi K40S has a price in the domestic market of 6.5 million. However, due to the policy of tightening the border, during this time, the number of laptops on the Vietnamese market is quite limited, as well as the price being pushed up. The standard 6GB/128GB version of Redmi K40S is currently being sold in Vietnam for about 7.9 million VND (refer to the Hay Phone store).
In fact, the price of 7.9 million VND is not a very attractive price. In this price range, users can completely choose the POCO F3, the renamed version of the Redmi K40 with the same Snapdragon 870 chip, the price is even cheaper.
