For those who have the ZTE Axon 7, you have a new update rolling out to you that brings a lot of improvements. The update has just been released so it will take a few days to get to everyone. Once you have it, you will have the August 2017 Android Security Update on your device along with multi user support amongst other improvements.
The multi user feature allows you to setup user profiles and those individuals can use the phone. This sounds very similar to the way native Android setups multiple users. You will also find that the Hiya app that ZTE uses for blocking spam calls has been moved to the Google Play Store for future updates.
Other improvements in this update to the ZTE Axon 7 includes a more refined control set for the night mode of the phone as well as improvements to battery efficiency and Google Daydream support.
There are several other minor tweaks to this update so it is well worth making sure you apply it once it is available to you. The update appears to be for all markets globally but as these things tend to go, updates are going out in phases to devices. It could be several days or weeks before your Axon 7 sees it. Patience is the key.
