After being silent for quite some time, Micromax is back with another Android Smartphone in its Ninja series, Micromax A91 Ninja. The device is up for sale with various online sellers including Saholic, Tradus etc. Micromax A91 Ninja is a Dual SIM Android smart phone which sports a 4.5 inch display running Android 4.0 on board. Underneath, it has been powered by 1GHz Dual core processor supported by PowerVR SGX531 GPU and 512MB Ram. The device is a perfect alternative for people considering Micromax Canvas 2 A110 bit large to fit in their palm. Micromax A91 Ninja packs a 5MP Auto focus camera but lack LED flash. It also features a front camera for video calling. It houses 4GB of inbuilt storage which is expandable up to 32GB via SD card. Connectivity options include 3G, Bluetooth, WiFi, Micro USB, GPS with A-GPS etc. The device is fueled by a 1800 mAH battery. Being a Dual core device, Micromax A91 Ninja is a good value for money device. However, absence of LED flash could be deal breaker. You may consider Lava Iris 454 (or Iris 455 with Jelly Bean) which offers a better specification for the same price.
