Q1: How do I upgrade the system of C800 to Android 7.1?

A1: For sure the system Android 4.4 is more stable than Android 7.1 for now. It is a cross-version upgrade if you upgrade the system of C800 from Android 4.4 to Android 7.1.

If you still like to do the system upgrade of C800, please contact our after-sales team by WhatsApp 0086 137 1470 3093 or email to support@toumeipro.com, our staff will send you the detailed instruction about how to do the system upgrade. 

You should prepare a USB cable with two male heads before doing the system upgrade.  Please follow the instructions step by step. if any question please contact us.

Thank you for your understanding and support.
