When I bought my Teracube 2e in May 2021, I did so with confidence in the promised long-term warranty and regular updates for a long time. But how much are such promises worth when there are obviously no updates at all?
My device (Android 10 - 4.9.190) works fine for the most part, but it never got any update. It reports a security update status as of November 5, 2020!!! A search for newer updates is fruitless and claims the device is up to date. I have a lot of understanding for difficulties of smaller startup projects, but after all this is not your first device, and such apparent neglect of security aspects I consider unacceptable!
A similar complaint - one of many - existed already before I had bought my device, almost a full year ago! You then promised a release within “the next 2-3 months”, but obviously it didn’t even happen until now.
You can’t cure unfulfilled promises with new unfulfilled promises. The lack of regular and timely security updates is nothing less than a serious product defect. So what are you going to do in order to really and sustainably fix it?
