The Razer Kishi v2 is not compatible with Android devices using the MediaTek Helio G80 chipset. This controller is primarily designed for use with a range of Android devices, but it relies on a USB-C connection, and compatibility depends on the phone's dimensions, button layout, and USB-C port placement. The dimensions you provided (158.9 x 73.6 x 8.4 mm) are within the general range, but the chipset and USB-C port compatibility are critical factors. Before purchasing, it's advisable to check Razer's official website or contact their support to ensure compatibility with your specific device, as support for different phones can vary.
