Samsung does not publish a list of every phone that the company has released. However, there are many websites, such as GSM Arena, Omio and PhoneArena, that have put together comprehensive lists of Samsung phones.
GSM Arena has published an extensive list of Samsung phones that stretches back to the SGH-250, which Samsung released in 1996. Its list includes photos, specifications and release dates for every Samsung phone it includes. Other websites, such as Omio, have published photo galleries of Samsung phones, but Omio's list is not exhaustive.
In addition to phones, PhoneArena provides information about other Samsung devices, such as tablets. PhoneArena also publishes information about upcoming devices that are not yet on the market.
