Hi Justin, Now i can install it on my Huawei phone. I followed the instruction from Kaspersky Support team. Please note that, "Occasionally, during the initial configuration of Kaspersky Endpoint Security for Android on the user's device, the device may fail to connect to Kaspersky Endpoint Security Cloud. In this case, the user must remove Kaspersky Endpoint Security for Android and install it again. When the app is run for the first time, the user can copy the download link from the email message with the instructions, and then paste it in the Server field." so, if you have followed the steps in the above link, please try to uninstall the application and re-install it by pasting the download link in the (from email) and paste it in the server field. It works for me now.
