Ulefone S1 Pro 4G Phablet

Ulefone is a Chinese manufacturer who has recently undergone a re-branding and decided to change its strategy, focusing on the quality of the proposed range. One thing remains unchanged – these are smartphones of the lowest price category, which are created using most fashion trends and get quite good features. The new budged phone Ulefone S1 Pro was not an exception to the rule, having received a stylish case, but a review showed that not everything is as perfect as we would like. Just see its younger brother Ulefone S1.

Looks like the smartphone Ulefone S1 Pro is boring and uninteresting, being lost against the background of similar competitors. He received the main trends of 2018 – a double rear camera and an 18: 9 screen in front. True, it is not so large in size, which has become a peculiar advantage. The display diagonal is only 5.5 inches. But on the characteristics of the screen Ulefone S1 Pro decided to save, and therefore it works under a low resolution of 480 x 960 pixels, which gives a weak detail of the picture. This is bad even considering its cost, especially since the picture also fades strongly in the sun. But otherwise the image is bright and looks decent for its price.

Specifications – weak weakness of the smartphone Ulefone S1 Pro, because they are barely enough for the normal operation of the interface. They are very outdated – the Mediatek MTK6739 processor is paired with a weak Mali-500 MP2 video chip and only 1 GB of RAM, which is nonsense in 2018. Not less than funny looks the amount of internal memory in 16GB, at least MicroSD can be installed and thanks for that. The 3000 mAh battery lasts for a couple of days of autonomous use. The capacity is small, but here the plus will be weak characteristics and screen resolution.

Although the main camera is double, it is represented by very weak 13.0MP and 5.0MP modules with a poor aperture. They are enough except for photographing documents, noise appear even on daytime photos. You can buy a Ulefone S1 smartphone only if you need a simple work phone with minimal features and an affordable price.
