We rarely use switch in our code. Can you replace it with if-else?

After appending primary it is no longer a base label - doesn't matter that much, but maybe we can make the naming less confusing.

Why do we use a TouchableOpacity without onPress? If the component isn't pressable, we shouldn't use a component that handles pressing.

Nice find!

I think that's a good idea. I might prefer to use (this device) to make it more consistent with (primary). We should also consider how to format a device when it is both the current device, and the primary device

You can avoid having to name the final result:

const baseLabel = deviceID.substr(0, 7);
if (!isPrimary) {
  return baseLabel;
}
return `${baseLabel} (primary)`;

Could potentially also combine the last four lines into a single-line ternary

Yeah this doesn't make sense to me either
