Quick Summary
Tecno has teased a concept device claimed to be the industry's slimmest.
The Spark Slim is said to measure just 5.75mm thick, yet still have a 5,200mAh battery and a dual camera on the rear.
It seems slim is the latest thing when it comes to smartphone design. There have been several rumours surrounding an iPhone 17 Air over the last couple of months, Oppo announced the world's thinnest folding phone in its Find N5, and Samsung teased the S25 Edge during the launch of its current flagships.
