Smartphones with quad-core processors seem to be presently the most desired handsets while the ones with single core processors are almost obsolete. As a result of this changing scenario, manufacturers bringing newer dual-core models have to make sure that their product is different from the already available ones. LAVA has a new dual-core smartphone for its consumers and we take a look at what differentiates it from the rest.

Design and build quality
With most smartphone manufacturers trying their best to be ahead of the competition, they seem to be concentrating on the display types and sizes. While some are larger, others sport a better quality (Super AMOLED or IPS panels). As per our short informal (internal) survey, a display at 5-inches or higher is inconvenient to handle, needs two hands to operate and is usually prone to accidental falls. A display screen between 4-inches to 4.7-inches seems like an ideal size, which also makes the chassis slimmer and with a comfortable grip. It also makes it easier to operate with just one hand. Similar is the case with the iris 455. Sporting a 4.5-inch display, the phone has a comfortable size and grip. The chassis is made from tough polycarbonate and is very firm. The matte-finish exterior – with dual-tone black and steel-grey shade and a silver trim along the edges – gives a good aesthetic touch. The rear panel is removable and can be replaced with a black one that comes free with the package.
512MB RAM, PowerVR SGX531 GPU, 4GB internal storage
The front panel is an all-glass display with three backlit capacitive buttons at the bottom and the earpiece and front camera on the top. The backlit buttons are a bit dull during the day, but they are clearly visible during night time. A unique feature seen for the first time on any smartphone yet is the charging LED notification. The moment you connect the charger to the phone, the Home button glows red till the time the phone is charging and turns green when the battery is full.

The left side sports the power switch and volume rocker while the top features the microUSB interface and the 3.5 mm audio jack. The rear panel highlights the 5MP camera with an LED flash and a speaker grille towards the bottom. Below the rear panel are the slots for the two SIM cards and the microSD card. Behind the rear panel is a strange black sticker (below the camera window) coated with metal; it seems like some type of a radiation shielding material for the SIM cards. Overall, LAVA seems to have done a good job with the looks and build of the iris 455.
5MP camera with LED flash, 1500 mAH battery, extra replaceable back cover
The iris 455 is an extended version of the iris 454. It is a dual-SIM (GSM + WCDMA/GSM) Android smartphone and is built around the MT6577 chipset that features a dual-core 1GHz processor along with a PowerVR SGX531 graphics processor along with 512MB of RAM. The internal storage is 4GB, which can be extended to 32GB via the microSD card. The display is a regular 4.5-inch capacitive one with a resolution of 960 x 540 (qHD), unlike the older sibling, the iris 454, which had the same specs on an IPS display. The main shooter is a 5MP camera with AF and an LED flash, whereas the front camera is a simple VGA. The phone is powered using a 1500 mAh battery and the operating system installed is the latest Android Jelly Bean v4.1. We do not have any confirmation of the update for v4.2 on the iris 455 as yet. Lastly, the entire handset weighs just 120 grams and the thickness stays at 9.9 mm.

We ran our usual benchmarking tests to know the core strength of the internal hardware. AnTuTu scored 5426, Quadrant scored 2352 while Nenamark2 scored 24.1 fps. Linpack gave us results of 39.6 MFLOPS and 62.6 MFLOPS in single-thread and multi-thread tests respectively. Sporting just 512MB of RAM, the phone seems to run sluggish at times. Regular users installing multiple apps might get to see this slowdown a few times a day.
The top sports the micro USB PC interface and 3.5 mm audio jack
