Background
Nokia is a Finnish company that specializes in telecommunications, information technology, and consumer electronics. Modern Nokia smartphones are manufactured by HMD Global.
In the 2000s, Nokia released four series of smartphones. This included the C series, X series, E series, and the N series. Within each series are numbered phones, generally from 1 to 9. This number corresponds to the feature set and price, with 1 corresponding to a lower-end budget phone and 9 to the flagship. The company has moved away from their old naming conventions, however, so the number of your Nokia model may not reflect its features.
Nokia faded out of the smartphone scene for most of the early 2010s. However, in 2017, the release of the Nokia 1 marked a new generation of Nokia phones. The ‘new’ Nokia phones run on the Android OS, and have a lot in common with Android phones. However, they still have the classic Nokia branding.
Identification
Check the physical appearance of your phone for any visible Nokia branding. Look for the word "Nokia" or the Nokia logo on the front or back of the device.
