Oukitel backs itself to surpass others such as AGM and Ulefone to become the brand with the rugged smartphone of the loudest (and largest) loudspeaker system. The WP22 may also outdo its rivals with a 10,000mAh battery - not to mention Android 13 out of the box. It will debut with a MediaTek Helio-series SoC and 8GB of RAM later this month.
