I certainly wasn't wowed by the rear camera on the BlackBerry Key2, but I was pleasantly surprised by the images it captured.
TCL added a dual 12-megapixel rear camera this year — the BlackBerry KeyOne relied on a single lens. In general, I found the photos to be quite sharp, and was continually impressed by how the camera handled close-up shots. Again, the rear camera wasn't phenomenal, but to be perfectly honest, it was better than I expected from a BlackBerry.
The selfie camera, on the other hand, was one of the worst I've used on a smartphone in the last year. The camera has a fixed focus, and most of the time my selfies came out blurry. Even when the camera seemed to focus on my face, the images were rarely as sharp as one would find on an iPhone, Google Pixel, or Samsung Galaxy phone.
That being said, I doubt the target audience for the BlackBerry Key2 consists of a lot of avid selfie-takers, so it likely won't be an issue for most people.
One surprising thing about the entire camera system is that it's unlike any other Android camera I've used lately. Most Android phones pack their cameras full of so many camera features, you feel like you have a DSLR in the palm of your hand.
But the BlackBerry Key2 doesn't have any of that — only a few filters, no advanced camera adjustments, and none of the weird face-smoothing features I've found on phones like the Samsung Galaxy S9. It's the simplest smartphone camera I've used in years, which was actually rather refreshing, since I rarely end up using those anyway.
