What is the difference between a mobile phone, smartphone and tablet?¶

A mobile phone is built primarily for mobile-network calling; a smartphone adds a general mobile operating system, apps, sensors, internet services and substantial storage; a tablet provides similar computing capabilities in a larger form and may have no conventional telephone service.

Device type shapes likely evidence¶

A basic phone may principally hold call, SMS, contact, limited media and network-identity records. A smartphone can add application databases, cloud accounts, notifications, location artefacts, browser data, photographs and links to wearables or computers. A tablet may hold much the same material, including messaging and calling-app records, whether it connects through mobile data or Wi-Fi alone.

These are starting expectations, not guarantees. Hardware, operating system, configuration, app use and account state determine what a particular device actually records and what remains with providers.

The category does not identify the user¶

Tablets are often shared in homes, schools and workplaces, while a phone registered to one subscriber may be carried or used by someone else. Device type, purchase and subscription each support different propositions.

Record model, state, accounts and connections and follow the relevant identifiers rather than the marketing name. The next question is what is stored locally, cached or held elsewhere, because no smartphone is a self-contained history of everything done through it.
