Dual-camera phones were first introduced by Samsung in 2007, but they didn’t gain much attention until around 2016—when LG released the LG G5—that dual cameras began to take hold and dual cameras became almost standard on most smartphones.
In general, dual-camera phones give you access to features that were previously relegated to high-end DSLR cameras. With them, you can achieve bokeh, wide-lens shots, and even 3D photos from your phone.
Most dual-camera phones only have two cameras on the back of your phone. However, a few models do include a second lens on the front of your phone, for taking wide-angle selfies. Those with a single camera on the front and a single camera on the back are considered two-camera phones, rather than dual-camera phones.
