Dual cameras have been here for quite some time, and now triple and quad camera phones are quickly becoming mainstream. Having two, three or four cameras might not be much, but it&rsquo;s what they offer to the end user that makes these smartphones interesting. Most budget dual camera phones would only have a depth sensor for portrait shots, but with triple and quad camera phones coming in, the options have only increased. Triple and quad camera phones now offer the ability to take wide-angle and macro shots along with a telephoto lens sometimes that offers optical zoom. And all this doesn&rsquo;t require you to pay a large price. In fact, the cheapest quad camera phone is now under Rs 10,000.
