Alcatel Flash is among the first phone's, if not the first, which comes with a dual-lens camera for both the front and rear sides. It's great to see that Alcatel, which is a less popular player, is the one to invested in this unique feature. The Front comes with a 8MP + 5MP dual front cameras, both with F2.0 6P aperture lenses. Now listen to this, you also get a Dual Tone flash and a PDAF, as well what more can you ask for a front-facing camera to take beautiful selfies which will always be in focus. One of the sensors is and RGB one and the second is a monochrome one. The Super Selfie Mode allow users to change the focus point or choose different blue levels during the image composition or after taking the shot.

The same great features, including a 6P (6 element) F2.0 aperture lens, Dual-tone flash and PDAF (0.15s focus speed) are available on the rear. However, this time you enjoy a 13MP dual rear cameras, which result in higher resolution images and this allows the phone to capture images with superior image quality, dynamic range, better noise levels, color and details using the Super Selfie Mode. The dual lens camera also allow the front camera to produce photos with a shallower depth of field effect, which is great for self portrait shots (selfies).

I can now understand why Alcatel has given this phone the name "Flash", which is a classic name for a phone that put a great deal of attention on the photography aspect.

The rear dual cameras uses the 1/3.06in Sony IMX258 sensor, which is the same sensor found in the LG G6, Allview X4 Soul, Oppo A57, Asus Zenfone Pegasus 3s and BLUE Vivo 6 among others. I've seen many sample images taken with this mid-range sensor. As a standalone is produces mediocre low-light performance, but it performs amazingly well in low-light. Given a f2.0 lens (not f2.2) and dual-sensor camera setup, we can expect better low-light performance from the rear camera. I think it's a great choice to use this sensor for the rear and I hope that the result will meet my expectations, which should be better compared to a single IMX258 camera setup because of the second monochrome sensor which its data can be used to enhance the image quality. Monochrome sensors don't capture color data, but they capture the full intensity of light in each pixels, which using certain image processing algorithms, can enhance the image quality on phones that use a dual-lens camera setup.

Another nice feature that the rear camera has is that it features a sapphire crystal lens cover, which helps to make sure that the lens won't get scratches. This is one of the hardest glass materials in existent, so you can rest assured that the Alcatel Flash lens won't get scratches, maybe all of its life time. I have a wrist watch with me with sapphire crystal glass for over 20 years, and it never got scratches even once.

This is a significant advantage that the Alcatel Flash has versus its competition in the mid-range segment.
