Got my unit and it's super wobbly in the Garmin (non original) mount. Anyone else experiencing the same problem?

Spec sheets only tell half the story here. The interesting part is that the Karoo 3 UI actually runs on the Alpha/Xcadey 800 hardware (2GB RAM, Android 8.1). That says a lot: Hammerhead's software doesn't need 4GB and Android 12 to function. Much of that extra headroom on the Karoo 3 goes to the OS itself, not to the app.

Android 12 isn't "worse" (it brings newer security patches, better BLE handling, 64-bit), but it's a heavier OS. On a bike computer, where the workload is basically maps, sensors and a screen, a leaner Android 8.1 isn't the handicap the version number suggests.

Also, comparing CPUs by GHz alone is misleading. Core architecture and process node (12nm here) matter more than the clock figure. So "similar to the Karoo 2" undersells it. Hardware-wise it sits somewhere between the two, at a fraction of the price.
