    My phone is the Samsung Note 9 with the latest software so I get this message when I try to do an update my Matrix. However I have found a work-around! Since I don't keep older phones in working order I tried to do an update with my Samsung Tab S 6 Tablet. It worked! Now the info on the tablet:

    WIFI only. No LTE, No 5G.

    Android 10

    One UI 2.1

    Kernel: 4.14.117.18134382

    Security: 1 March 2020

    The only problem is that I have now paired my Matrix with my 10.5 inch tablet. Not easy to lug a tablet around with my bicycle, but then again the Note 9 is no easy feat either. Smirk!

    If you want more information, email my user id.

    Thanks for sharing this with us and other Lumos helmet users, John! 

    Although our app may run on a tablet, it is designed for smart phones only. As you mention it is also not as convenient to carry a tablet with you. Once you have updated the firmware using your tablet, I recommend you to unpair the helmet with the Lumos app on the tablet. Then pair it up with your Samsung Note 9 again and you will be able to use the app on your phone as usual. 

    Feel free to write us at support@lumoshelmet.co if you would have any feedback or questions.

    Love the hardware, but after spending so much $ just to find I also need to locate a different phone to update firmware is disappointing.

    Not easy for some of us to find a different device to perform a firmware update.

    I am not an Apple user, nor will I ever be. Are there any updates for Android users?

    Hi TJ, we understand that the proposed solution is not ideal and our software team is working hard to make the firmware update work for Samsung phones on Android 10 as well. We will let you know once there is an update.

    Thanks for the reply Monique. I was able to get it updated with an old S7.The Matrix goes with the electric unicycle lights perfectly on night rides.
