  1. 10s of people are asking the same question. How can I pair? Syncronise with my phone blah blah blah. Author has clearly answered that it’s an independent phone and can’t be paired. You guys don’t read or what? Or you are harassing him asking the same question?

    • This is an independent watch phone. It can not pair up with your phone to receive messages or calls.

  2. I purchased a K9 with android 4.4.4 for a friend and she says wifi isn’t working. Actually she says wifi networks are not even coming up. Is there any initial updates that need to be done before wifi works on these watches?

    • Actually, no initial update is needed. It should work out of the box. It seems your smartwatch has some issues with WiFi. Try to check any firmware update is available for the watch or not. Sometimes an update can solve many issues.

    • Please remember, this is an independent watch phone. It can not pair up with your phone to receive messages or calls.

  3. Hello, I really need Your help….

    I can’t pair this watch with my Xperia Z3C. Both devices recognize themselves in BT options menu, but nothing happened. I can’t recive calls and messages. When I try pair phone and watch in “Watch Helper” there is “no connection” status. I actualized soft in phone and watch to newest versions. I’ve tried install another aps like “Smartwatch” for example but still no work.

  4. I have this smartwatch. It does not come with google play but there are wireless updates. The last update installed google play. Be sure to use a battery saver program or the watch might not last long. You can then use google play to install apps from the net directly to the watch. It’s sturdy and I use it at the gym for music and I will probably also use sworkit app for my jump training with it. After installing the avast battery program I can charge at 10 AM and then use it for music in the gym and then it will last the rest of the day (very light usage and I had about 56% battery life the next morning. Not bad.

  5. Thanks for the review.
    – Is the heart rate monitor 24×7 continuous or only when you manualy activate it?
    – Is it possible to install other apps on the watch via Google Play Store, like new watch faces or gps apps?

    Thanks in advance,


    • 1) Heart Rate Monitor: You need to manually activate it.

      2) Yes, you can install app from google play. The google play app is not installed by default. You need to install that also.
