Knowing what kind of Samsung phone you have is important if you want to update the phone or buy accessories, like a phone case. While there are multiple methods to find your phone's model, not all work on every phone. For example, some phones don't have a removable back plate and battery, preventing you from finding the information that way.
Behind the Battery
If your Samsung phone has a removable back plate and battery, you'll find information pertaining to your phone model there. While some phones and carriers might list the phone's actual model name, you might just find a model number. If this is the case, find the model name by entering "Samsung" and the model number into a search engine. Alternately, visit Samsung's support site (see Resources) and enter the model number to get more information about your phone, including its name. Before removing your phone's battery or back cover, make sure you've turned the device off.
If your phone features Bluetooth connectivity, navigate to the device's Bluetooth settings. Every Bluetooth device needs a name so you can pair it with other devices. According to the Mobile Fun website, the default name is often your phone's model number. Take the name listed and enter it, plus "Samsung" into a search engine to find out which Samsung phone you have.
If your Samsung phone uses the Android operating system, you can find out what kind of phone you have through your device's settings. Open your Android Settings menu and select "System," then "About Phone." Here you'll see the the phone's model name or number.
Box and Manual
If you still have the box the phone came in, you'll find the phone's name listed somewhere on there. It may be on the box, itself, or on a sticker placed there by your service provider. Alternately, the phone's manual likely mentions the type of phone you have.
Visit your mobile carrier's website and log in to your account. You may be able to find information regarding your phone, including the model, here on the website. You can also visit Samsung's mobile site and browse through their available phones, visually inspecting them until you find one that looks like yours. If all else fails, call your carrier, they should be able to quickly identify your device for you.
Instructions for accessing the phone's "About Phone" menu pertain to Android 4.4. Instructions differ in older versions.
