@Shanling I just got my M5s. Love how the device sound. I can hear the upgrade from my M2s and M0 that I own. I have a question regarding the Hiby Link feature. As far as I understood parsing through and search the thread mTouch OS replaced the Hiby OS in M0 and M5s, so the Hiby Link feature has been dropped off. I really love the Hiby Link feature in my M2s, will there be an App to interface with the M5s the same way?
