4-5 random bluetooth headset disconnects per day after installing. Apparently a known and long standing issue for multiple combinations of phones/watches/headsets. I am currently using an LG G5 with a Huawei watch, and a Plantronics headset. Not catastrophic, but annoying as hell. Web searches show that it has been an issue far longer than it should be.
Foreword, I'm running rooted with custom ROM, but I've never had this problem until recently. All other notifications seem to work fine with no issues other than google play music. Occasionally I will get the notification to pause/play and control the volume but often times nothing will show up at all. When I do get the notification, the song title is only correct for one some and then fails to update for the next. I haven't had these problems until the update to 2.0.
UPDATE: Review changed...had to unpair watch again and reset watch and then forget watch and application data on phone. Notifications are coming through now. Latest update broke Notifications on Huawei Watch running Android Wear 2.0 developer preview. Hopefully fixed for consumer release version.
Bluetooth music skips when wifi, GPS, NFC, & cellular data are all turned on. If you erase or forget the bluetooth connection you need a phone to connect again! Not a good set up if your in the middle of a workout and your trying to fix your Bluetooth. Why doesn't the LG Watch Sport automatically have all my existing wifi SSID's & passwords? I have to enter them all over again at initial set up! Then once I'm on wifi Android Wear 2.0 still downloads apps via Bluetooth instead of wifi. Feels like a first year device. Not compatible with Google Fi! Cause that makes sense... Works with an iPhone but not with Fi.... Let's make it compatible with our competitors product but not or own.
For anyone having issues download the Jan 26th version from apkmirror. It solved all the issues I was having. Looks like they disabled support for the Android wear 2.0 Dev preview in the latest version as everything stopped working since this last update
DOESN'T PLAY WELL WITH LEXUS ENFORM APP. Android Wear 2.0 doesn't let the Lexus Enform App load when starting the car therefore the infotainment system does not tether with the car so nothing works, no phone, no Pandora, no contacts etc. I'm using a Pixel XL paired with LG Smartwatch Sport to an IS 200t
