If I run Pokemon Go, there is an error as shown below, why is it?

The Pokemon GO cannot be driven because the device OS version you are using is not compatible or a specific operation (such as ROOT) is detected.

Pokemon Go is not allowed when routing.

If you break out of iPhone because it's routing, you can't play games.
Otherwise, it might not work because the Android version is low because it's my old phone.
