We aren’t great fans of light-flashing phones. So, when KDDI and Kyocera decided to release the W64SA with embedded LEDs for ‘color therapy’, we couldn’t help but say ‘duh!’. The LEDs, when switched on, display their resplendence through the translucent cover at the back. A reflection plate behind the lights adds to the effect. If you love a hippie thing, the W64SA isn’t a bad choice though.
