Lightning App Builder supports visibility rules based on Device/Form Factor , allowing components to appear specifically on desktop or phone experiences. This lets the app builder streamline the mobile record page by displaying only the components and information mobile sales reps actually require while leaving the desktop experience unchanged. Salesforce explicitly documents that a visibility filter using the Device context can restrict a component to a particular experience, such as phone or desktop. Reordering all fields would modify the experience broadly without providing device-specific optimization. Disabling the phone assignment would remove the page from the required mobile experience rather than improve it. Better training documentation also cannot solve excessive UI complexity. Therefore, device-based visibility using Form Factor provides the required declarative, low-impact solution. Salesforce
