Many recent Xiaomi smartphone models have a firmware block that prevents 3DMark from making network connections. Even when your phone shows that it is connected to the Internet, this firmware block will prevent 3DMark from connecting to our servers to download and install benchmark DLC files and device list updates. In the 3DMark app, you will see an hourglass icon in place of the download/run icon.
The firmware block works by detecting the name of the 3DMark app and appears to be intentional. Unfortunately, we have no workarounds or solutions for this issue at this time. You will not be able to use 3DMark on affected devices until Xiaomi updates its firmware.
Please contact Xiaomi customer support and ask them to stop blocking the 3DMark app.
