Hi All,

I have receive for Christmas a SW3.
I already have a LG G2 (D802) running Lollipop :

With Render Kernel :

I have update the SW3 to official 5.0.1 with PC Companion.
Then install Android Wear from the market on the phone :
https://play.google.com/store/apps/d...able.app&hl=fr

I had "Sleep as Android" app already installed on the phone before get the watch.

I have connect the watch to the phone then I have try to install different apps as :
https://play.google.com/store/apps/d...arminilauncher
and
https://play.google.com/store/apps/d...ur.wearbrowser
Without problem, the apps appear on the watch., "Sleep as Android" too.

But now, I can't success to install any other apps. I have try :
https://play.google.com/store/apps/d...wearcalculator
Or
https://play.google.com/store/apps/d...o.hoomi.athere

But the apps doesn't appear on the watch, I don't understand how to sync the phone and the watch.
I guess I'm too new and there is something that I haven't understand.

Please someone drive me !
Thank you in advance.
