Thus to help you, we have here listed five smartphones that pack a fair combination of both - camera app and great imaging hardware. Of course all these smartphones have a front facing camera but the idea is to make the best of the rear camera.

Nokia Lumia 1020

Nokia introduced its imaging flagship - the Lumia 1020 - running Windows Phone 8 platform last year. The Lumia 1020 succeeds the previous imaging flagship - 808 PureView. Nokia has used a 4.5 inch AMOLED display with 720p (HD) resolution support and is made using Corning Gorilla Glass 3 for strength. Lumia 1020 is powered by a dual core 1.5 GHz Qualcomm Snapdragon S4 Plus MSM8960 mobile processor, 2 GB RAM and 32 GB on-board storage without any memory slot. Nokia has pushed the new Lumia Black update packing Windows Phone 8 Update 3 to run this smartphone.

Nokia has armed the Lumia 1020 with a 41 megapixel camera with 1/1.5-inch image sensor. Nokia's own PureView imaging technology is implemented to power the 41 megapixel image sensor. This image sensor has been married with Carl Zeiss optics. The Carl Zeiss optics comprises of a six element lens - five layers of plastic aspheric lens and one layer of high precision glass. Out of the Dual LED flash at the back, one is a Xenon Flash and other is meant for auto-focus assist. Nokia has used a f/2.2 aperture that captures wider angles and allows more light to reach the image sensor. Nokia Camera app enables more manual control of the focus, white balance, exposure and more. The only option missing so far is manual f-stop control.

For better optical image stabilisation, Nokia has deployed ball-bearing like cushions to reduce shake movements. The camera offers 4x lossless zoom and re-cropping technique (Zoom Reframe) with the new Nokia camera app. The HDR has been integrated in the form of Automatic Bracketing accessible through the camera setting options. High quality images in 34 megapixel can be captured but these images are accessible only by using a computer. Usually, the images are saved in 5 megapixel quality with PureView technology implemented. The Lumia 1020 offers slightly saturated colour which is fairly acceptable for imaging hobbyist.

Apple iPhone 5S

Apple had introduced the iPhone 5S in India two months and continued to offer previous generation iPhone models as well. The new iPhone 5S has a 4-inch Retina display based on IPS LCD panel technology supporting multi-touch and 1136x640 pixel resolution. Apple iPhone 5S is powered with Apple A6 System on Chip and M7 motion processor. Apple has loaded the phone with iOS 7 software and 1 GB DDR3 RAM. Apple offers this model in 16 GB, 32 GB and 64 GB storage options. Other features include dual-band WiFi, Bluetooth and Lightning connector to charge the device.

The Apple iPhone 5S comes with an 8 megapixel iSight camera with 1.5 micron pixels quality. The camera sports f/2.2 aperture that captures wider angles and collects enough light necessary for capturing images in low light conditions. Apple has used a five element lens that has a Sapphire crystal lens cover. It has also dual-LED True Tone flash to provide better colour temperature to the photos. This flash is meant to help the imaging enthusiasts in the low-light imaging to get better colours in the resultant photos. This sensor is larger than the one used in the iPhone 5 and also promises better low light photography results.

To tackle the Ultra-Violet light problem, Apple has armed the phone with the Hybrid IR Filter. Apple's Camera app is taken as the standard for being super smooth and fastest one on the mobile platform. The Camera app offers tap-to focus feature along with face detection, burst mode and taking panorama shots. Apple has also integrates a square imaging mode with a library of live filters for the Instagram lovers. The camera is capable of recording smooth 1080p videos with image stabilisation. One can also experiment with slow-motion video recording. Entire imaging is powered by the quad-core PowerVR G6430 graphics. There is a 1560 mAh battery in the phone.

LG G2

LG G2 is loaded with 5.2-inch True HD-IPS LCD display with 1920x1080 pixel resolution. This display has been constructed using Corning Gorilla Glass 2 technology. LG has housed the quad-core 2.2 GHz Qualcomm Snapdragon 800 MSM8974 mobile chipset with Adreno 330 graphics chip. LG has equipped the G2 with 2 GB RAM to run most things with Android 4.2.2 Jelly Bean update smoothly. For storage, the G2 offers 16 GB on the phone and memory slot to add in the micro SD card slot.

LG G2 has a 13 megapixel camera with autofocus and LED Flash. G2 has the power key just below the camera. Though it is something different, the camera lens ends up with smudges when the finger searches for the power button. The volume button is to be used for launching the camera app from the sleep mode. From several Android based smartphones, G2's camera is quick in capturing images. LG has packed only one LED flash which may not be ideally enough but still does the job. Touch to focus, forced flash and other modes stay consistent even in the G2. LG has packed about 12 different shooting mode options for the user to choose from. These modes include the HDR and Panorama imaging for some really great experimental shots. The catch in getting the full 13 megapixel image quality photo is to shoot the subject in the 4:3 aspect ratio else it turns out to be 10 megapixel in 16:9 aspect ratio. The size of the handset is slightly big and is not easily usable by one hand for quick photo captures. The G2 offers very pleasant imaging in the good lighting conditions. LG has packed 3000 mAh large battery to keep the phone running for a day or more. Read our review of LG G2 here.

Samsung Galaxy Note III

Samsung Galaxy Note 3 flaunts a 5.7 inch full HD Super AMOLED display and a 1.9 GHz Samsung Exynos 5 Octa processor. The processor consists of four Cortex-A15 processing cores, clocked at 1.9 GHz, to take care of heavy processing and four Cortex-A7 cores which are clocked at 1.3 GHz to take care of low end computing, offering battery savings and performance at the same time. Galaxy Note 3 comes packed with 3 GB RAM. Samsung has added 32 GB internal storage and memory slot to support up to a 64 GB micro SD card. Samsung has layered the Nature UX to run Android 4.3 Jelly Bean update smoothly over powerful hardware. The S Pen experience has been improved to offer better functionality. Samsung Galaxy Note 3 offers WiFi (802.11 a/b/g/n/ac), Near Field Communication, Bluetooth 4.0 LE, IR LED blaster, MHL 2.0 and GPS with GLONASS support.

Samsung introduced the Note 3 with a 13 megapixel BSI sensor based camera with auto focus and LED flash. Samsung has tried to package all the best features in the camera app offering several modes. For instance, the Android's Photo Sphere - a 360 degree panorama shot feature has been offered as Surround Shot. The user interface of the camera app also been tweaked so that the carousel effect is experienced while choosing between one of the shooting modes. The arrow at the bottom throws in bunch of live filters to choose from. The Best Shot and Best Face feature allows the user to select a portion of the photo to change it. One can simply go about clicking great images with the HDR and other shooting mode options. The Galaxy Note 3 becomes the frontier to allow recording Ultra HD quality video in 3840x2160 pixel resolution at 30 frames per second. Also, the user can always go for a super fluid 1080p HD video at 60 frames per second. The only thing this phone might take a backstep is the optical image stabilization. However, the quality of the images and the video is top class. Samsung has packed 3200 mAh battery to make it run for a day's time. Read our thoughts on the Galaxy Note 3 here.
