I am running 4.23 firmware, and am generally now quite happy with the performance of my 830 regards to accuracy etc.
I am just running the unit in its own, with no peripherals attached, not even a mobile phone.
However on most rides I am constantly experiencing sporadic freezing.
The device is still working, I.e the speed with still be active, but the screen is unresponsive.
After about 20 seconds or so it will start working again, but then repeat.
You only realise it is doing this when you try to swap data screens or zoom in on the map and it will not respond.
Anyone else experiencing this?
