Samsung Galaxy phones: A series or S26 series
Samsung Galaxy phones split into two main lines. The Galaxy A series, with the A17, A18, A27, A37, A56 and A57, focuses on everyday use with large 6.7" screens and triple cameras built around a 50 MP main sensor. The A17 and A18 come in 4G versions, while the A27, A37, A56 and A57 use 5G, and models such as the A27 and A57 add optical image stabilisation on the main camera.
The Galaxy S26 series sits at the top. The S26 has a compact 6.3" screen, the S26+ moves to 6.7", and both use triple cameras with 12 GB of memory. The S26 Ultra has a 6.9" display, a quad camera led by a 200 MP sensor and storage up to 1 TB, paired with 16 GB of memory on that version.

The Galaxy A17 4G and A18 4G use 4G only, which is fine for calls, messaging and everyday browsing. The A17 is also available as a 5G version.
