Android smartphone dual SIM

Salora Powermaxx Z1

This is Salora's first Android phone with dual SIM, called PowerMaxx Z1. And why do we have a handset from a new brand in this list? While you can also read our review to know more, a look at the specifications will suffice too. It has a 3200 mAh battery, which is the largest-even some tablets don't get that big a battery. And that's not all, it is slim even with that size of battery thanks to a 4.5 inch qHD IPS display made with zero gap technology, which means better readability in the sun, a wider viewing angle, and a slimmer phone. That's not all; you also get noise cancelation for better call quality and on top of that very decent hardware with a Cortex-A9 1 GHz dual core processor and AAndroid Jelly Bean OS. The smartphone is made by forging aluminum alloy with a special fiber drawing technology.

The phone has 4 GB of internal memory and 512 MB RAM (1 GB would have made the phone all the more desirable,) and external memory is expandable up to 32 GB. The smartphone gets a 1.3 megapixel front facing camera and 8.0 megapixel auto focus rear facing camera. The camera also supports features such as optical image stabilization, panorama view, multi shot and time lapse video, facial beautify, smile shutter and automatic ambient light detection etc. And you get all this RS 9,999.00

Xolo Q800

Xolo recently launched its first quad core Android phone called Xolo Q800, priced at Rs 12,499. The Android 4.1 Jelly Bean phone has a 4.5 inch IPS panel display with qHD (540 x 960 pixel) resolution. Though it's not an HD display like the one on Micromax Canvas HD A116, due to its small screen size, Xolo Q800 has a decent 245 ppi pixel density compared to 293 ppi of the Micromax handset. Xolo Q800 comes with a 1.2 GHz quad core Mediatek chipset and 1 GB RAM as Micromax Canvas HD.

The Q800 has a 4 GB ROM. It has an 8 megapixel autofocus camera with backside illumination CMOS sensor for better low light photography at the back, which sounds better than the camera of Micromax Canvas HD. Q800 has a 1.2 megapixel camera in the front. Besides, the Xolo Q800 has 3G (up to 21 Mbps speed, which is again much higher than almost all other phones from Indian brands,) and WiFI, Bluetooth, A-GPS, a proximity sensor, and accelerometer. The Xolo smartphone has a 2100 mAh battery with a claimed 16 hours of talktime, which is definitely great as Micromax Canvas HD provides only 5 hours of talktime. Since Micromax Canvas HD is not readily available this one is a pretty good option and is in no way a compromise deal except if you want a larger display.
