Tecno promotes this device as the thinst telephone in the world, and its thickness is only 5.75 millimeters.

Tecno Spark Slim uses a 6,78% 3D screen coveted AMOLED (1224p) at a pace refreshing 144 Hz.

The maximum shine of the screen is 4,500. Spark Slim has two cameras 5 0 MP in the back while there's a phone camera 13 MP to the front.
The battery, with a capacity of 5,200m Ah, has a thickness of only 4.04 mm and supports rapid charge 45 W.
Tecno did not find out which chip strengthens the phone, only by stressing that he has a CPU with eight cores. /Telegraph
