    I just buy iwo4 watch. I want to ask you some questions :
    1. Why the charger change from wireless charger on iwo 2 & 3 to pin connect charger like on iwo 1?

    2. How do I change the start up logo from “sportwatch” to Apple logo as other can change the logo by pressing the button *#2015*# on the system version released on 2015

    Waiting for your reply as soon as possible. Thankyou

      hi, it need to get more accurate heart rate sensor, need to replace the wireless charger
      and for the logo, it need to reflash another firmware, thanks.
