Thanks mate - and nice to see you over here.
Did you manage to flash the I2 with that update I posted?
And yeah - love the floating square button - the KW88 uses same Sinsoft UI and launcher - it also has this function. It has helped me on many occasions !
Also like the ability to re-arrange the app layout . In the I2 there are 3 options, on the KW88 there are two options.
Both can switch to circular app draw though - very nice touch. I love the time preview as well - if you leave the awake on flip of wrist activated.
On both watches I have noticed that if the pedometer service is disabled you can save a lot of battery. Installing Doze from the Play store also helps a lot.
