Since the update android 5.01 wear everything went perfect. Excellent shows connected if you want to play sports. I wanted to free myself of the smartphone in my running sessions, so I have chosen this smartwatch 3 which was the only integrated GPS. Bingo! Thanks to the latter and application "My Tracks" I can run from lighter. When I return from my session, the watch sends all collected data to the app that is on the smartphone and can then analyze the results. Ditto for listening to music during my trip, it was enough to buy a bluetooth headset Sonixx X-Fit 40 and install on my PC google play manager to have my playlists then downloaded to my smartwatch 3. Playlists are recovered on the smartphone that send directly on my watch. I can then let the smartphone (Galaxy S3 with Android 4.3) at home. After you have lots of gadgets on the watch that work very well as read the mails and SMS; as vocally respond to these. There are also plenty of free apps to change the dials of the watch; I love change the style and color according to my dressing room the day (lol!). I am delighted with my purchase.
