Update (Nov 3, 2020): Wireless update system is back up now. Let us know if you run into any issues:
— Archive ----
Our wireless update (FOTA) system is down. So any new phones (or replacement units) might not get the SW6 or SW7 update automatically.
Please check your Build number at Settings > System > About > Wireless update. If your Build starts with Teracube_S1_05 (shipping version), then your battery and phone performance will not be good.
We are working hard to get the wireless update system fixed.
