Thanks for reaching out to us about this. We haven't heard about any instances of Geekbench 4 inaccurately measuring performance on specific versions of Android. I'll keep an eye out for reports which could indicate this, and let you know if it comes up.
In this case, the result could be due to differences between the devices that you're using, unless you're testing different operating system versions on the same device. Generally, results are expected to between instances of the same model due to manufacturing differences. The result could also be due to performance impacts of the new operating system version itself. Unfortunately, we're unable to diagnose performance issues on specific devices.
