Any manufacturer can just put two cameras side by side, two large dots next to each other. However that is lazy and unthoughtful design. How many cut out holes does the back of an iPhone need? It's unattractive, looks unresolved. Apple should think harder on this one. Maybe encase both cameras in a single rounded rectangle (pill shape) cut out with the appropriate dark masking in between. The technology should also be extended to all phone sizes including 4 inch.
