Innovation and nostalgia go hand in hand at the World Mobile Congress.

Despite the absence of the Samsung Galaxy S8, several brands took advantage of this year's World Mobile Congress to present their news. In addition to new equipment, the edition was marked by the return of two giants, NOKIA and Blackberry. But there we go.

Huawei presented the P10, its top of the range. This is a device that, thanks to a partnership with Pantone, is now available in 8 colors. In addition, its features have been matched to its Mate 9, including its 1.8 GHz Octa Core processor and the new Leica lens with two sensors, one 20 megapixel monochrome and the other 12 RGB. Despite all these innovations in relation to the previous P9 model, the P10 leaves us with the impression that the brand was not dedicated to its technical development, having limited itself to imitating the Mate 9. The P10 is also available in the Plus version. Values start at 508€ and 726€ respectively.

LG also presented its G6, a Smartphone that differs from its previous version for being a compact model and not made up of modules. The brand wanted to produce a compact device so that it had the IP68 certification, also present in the Samsung Galaxy S7 and S7 EDGE. Another of the novelties of this model is the change of the screen ratio from 16:9 to 18:9, thus allowing you to have a 5.7" screen in a small body. The processor is a Snapdragon 821, has 4GB RAM and 32GB internal expandable up to 2TB via micro-usb The G6 also has 2 cameras with 12 megapixels each. The value of the G6 is not yet known but it will exceed 700 euros.

The MWC17 was also marked by the return of Nokia with 3 Android Smartphones, the Nokias 6, 5 and 3. Alongside this we also saw the return of its famous 3310. It returned with a color screen, a 2.1 megapixel camera and talk time of 22 hours. The brand aims to reach emerging markets or people who use it as a second cell phone to always be in touch. The renewed 3310 will have the value of 49? and will be available until the end of the year.

Blackberry decided to go back to its origins and presented a device with a 4.5 inch screen along with its classic keyboard. In addition to this, the brand also decided to assign new keyboard functions to the KeyOne. This now also serves as a Touch iD and it is possible to swipe it. Each key can even be customized so that we can assign it a shortcut. The camera is also one of the bets, as it has the same sensor as the Google Pixel. We have 32GB of internal memory available up to 2TB, 3GB of RAM and a Qualcomm MSM8953 Snapdragon 625 processor. The KeyOne will be available during the next week and will have a base price of 500 euros.
