Micromax Bolt A 27 comes with 3.5 inch display, dual sim, android v 2.3 Gingerbread, 1GHz processor, 256 RAM and 512 internal memory. Resolution ( 480×320) px, Back camera 0.3 MP battery 1400mAH.
I am using it for 1 year. Battery backup is worst. It’s not even stay 4 hours. Phone is too slow. You can’t use 2 or 3 apps at a time. Sound is very loud. It hangs a lot. Camera quality is too bad. It don’t have a selfi camera. Style of the phone is very bad. Never buy this. If u want more features then get a costly one.
