AuPAD latest firmware/Security patches

Hello, i am aware Chuwi by design does not supply OS updates unless major changes.

I have an AUPAD, and works perfectly, but the last security updates were 13 months ago. As The device has Android on Vanilla spec should’t update or pull security updates at least?

If you have Aupad 14, it will be updated to Aupad 15 in June, you will receive a notification of the tablet
