Some consumers still look for older, vintage smartphones instead of new models with the latest features. Reasons range from cutting costs and retro design to a preference for specific features, but the most important factor when buying an older smartphone is security.

On Jan. 15, IT outlet TechRadar analysed standards for older smartphones that can still be used in 2026. The key is whether they receive security updates and operating system (OS) support.

The oldest model that can still be bought in "new" condition was Apple’s iPhone 12. On Android, Samsung’s Galaxy S22, Google’s Pixel 7 and OnePlus 12 series were found to still be in circulation.

Options widen when considering used or refurbished devices, but buyers must closely check security support. Apple provided security patches up to the iPhone 6S, released in 2015, through 2025 with iOS 15.8.5. It is theoretically usable, but older OS versions may limit running the latest apps.

For Android smartphones, Android 13 is classified as the security baseline based on Google’s security bulletin. The oldest model that meets this is Google’s Pixel 4, released in October 2019, and Samsung’s Galaxy S20 series and OnePlus 9 series can also run Android 13.

The standard for "current" models that support the latest OS is higher. The oldest device that can install the latest iOS 26 is the 2019 iPhone 11. On Android, the oldest device cited as supporting the latest Android 16 was Google’s Pixel 6, released in 2021. This is an example of a longer software lifespan than the Samsung Galaxy S22 released in 2022 or the 2023 OnePlus 11.

Extra caution is needed when using a device that no longer receives security updates. To minimise hacking risks, users should turn off wireless network (Wi-Fi) connections and remove the SIM card to keep the phone offline. They should also avoid entering sensitive data such as financial information, and transfer data such as photos by connecting via cable to a trusted device.

A retro trend has also brought renewed attention to discontinued older models such as the iPhone 4 among collectors and some users. Its distinctive camera colour and design are seen as evoking so-called "Y2K" sensibilities.

Ultimately, choosing an older smartphone requires a clear distinction between "practical use" and "collecting". If the goal is simply to enjoy retro sensibilities, it is better to block risky functions while using it, but for use as a main device, it may be reasonable to choose models such as the iPhone 11 or Google Pixel 6 or newer that still receive OS support from manufacturers.
