A growing number of smartphone brands are now switching to an alternative operating system called Kai OS to power budget phones that still do WhatsApp, Facebook and even voice control just as well as more expensive phones.
Designed to make essential smartphone features run on cheap hardware, the operating system is now set to be the backbone of new phones announced by Nokia manufacturers HMD Global and Energizer, including outdoor phone Nokia 800 Tough (€110 or RM512) and Nokia's 2720 Flip folding phone (€90 or RM419).
