The update is dedicated to bringing the security patches for the highly affecting vulnerabilities that were discovered in 2017. The incremental OTA is rolling out, which might take some time before it reaches every device worldwide.

While Oreo for Axon 7 is still a work-in-progress, the company has decided to update the device to comply with the latest security norms. The announcement was made the official ZTE community for the A2017U variant in the U.S. The new build includes the December 2017 Security Patch that addresses the highly spread Blueborne and KRACK vulnerabilities on the device. The former is related to the Bluetooth functionality on the phone, while the latter is concerned with the WPA2 protocol. Both the vulnerabilities could be potentially used to inject malware and access personal data. It’s a relief for the users that the OEM is finally pushing out the update for fixes regarding the two.

Apart from above the ZTE Axon 7 B35 firmware also includes general bug fixes and improvements and is based on Android 7.1.1 Nougat. It is clearly stated to disregard the release notes mentioning that the Hiya app has been reverted back to 6.3.3.
