i'm using a samsung gear s3 frontier along with my OP3T. notification works well. i can answer calls but I cannot text on the watch (not that I want to). spotify controller works well, and I can read flipboard articles on the watch to pass time. :
same issue here. both HRM app and SPO2 doesn't work properly as well (standing up or sitting down). it keeps on giving me extreme BPMs like 90+ or 100 while resting.
So I have been reading about all the Lollipop goodies that are coming out since last week and finally gave in to my temptation to take a bite and try an Android 5.0 ROM from the Development forum. I spent a couple of hours getting it all installed...
