Terra cube 2E and glucose monitor compatibility

I have a Teracube 2e. I’m trying to sync a glucose monitor to it that is continuous, dexcom 6. It is not linking up. It was suggested that it could be the operating system. I am on OS 11. If I upgrade my operating system to OS 12 how vital is it that I backup my whole phone? Has anyone had an experience with a glucose monitor and this particular phone? Thanks.

If you are going to go to a pre-release Build, I would recommend going to our Android 13 Beta instead of Android 12.

As with any upgrade to a pre-release build, backups of important photos/data are always recommended, but we have not had too many reports of issues with upgrades, as most folks seem to be doing just fine.

Unfortunately, no experience with a CGM, but I do have experience with other medical devices (hearing aids) which work acceptably under Android 13 Beta 2.

Do you side load the new OS?

Sort of. You are manually fetching the OTA image that will be applied by the system TeraCube Updater app like a normal OTA
