So i have had this ZTE Sonata 3 for about half a year and it has come to my attention that it will not pair with a pokemon go plus wristband. The device is bluetooth and it is running at or above bluetooth version 4.0. Now my problem is why won't the ZTE Sonata 3 pair with this wristband but every other device that i have tried it on connect just fine. The other devices i have used include a samsung brand phone, another ZTE device, which is the ZTE_N9511, and even my own windows 10 laptop, all of which connect fine. Any and all help would be much appreciated. I have already done a factory reset and that did not help. That was at the suggestion of the tech support chat-line that i went on to get help from ZTE. Although they were very helpful, my issue was not resolved. This is a picture of the device i am trying to connect to.
