Most phones these days have at least one camera – or more. The one that faces you is referred to as the “selfie-camera”, and the other is usually called the “main camera”. The one on the back is usually pretty high-end: several megapixels, image stabilization, LED flash, and oodles of more features. The one of the front usually is lower-end: fewer megapixels, no image stabilization, and an LED flash is all but non-existent.
Part of the reason for all this is space – camera modules are fairly bulky and take up quite a bit of space inside a phone. The other reason? Cost. Cameras are fairly expensive components, relatively speaking. One is expensive enough, but two? That’s just crazy talk!
To solve the space and cost concerns (and offer a high-resolution camera for both uses) some manufacturers have opted for a bit more “novel” solution: reversible cameras.
