1. About the phone: Xiaomi Poco F1

Having managed to make a decent noise in the media space, the smartphone of the new Xiaomi brand offers all the power of the flagship Snapdragon 845 processor and is cheaper than competitors. But miracles do not happen, so in the case of the Pocophone F1, it was not without compromises and “dust in the eyes”.

Performance isn’t usually the strongest point in mid-range devices, but the Pocophone F1 isn’t. Closer acquaintance reveals several compromises: materials, display, cameras. Also, the smartphone does not have NFC, and many will not like it.

The camera of Pocophone F1 is represented by two lenses – a resolution of 12 and 5 megapixels and a 20-megapixel front camera. In good lighting and outdoor daytime conditions, the main camera behaves quite decently, reproduces colours and does not overexpose frames. It is much more challenging to achieve success in the indoors and in the twilight. There is a lot of noise, and the lack of optical stabilization affects. By the way, during testing, the Pocophone F1 received two updates. They improved image processing and navigation buttons from AOSP were also included in the system.
