If you are searching low budget Android mobile with solid specification and features just go with it without thinking much.
This is correct, micromax doesn’t have much reputation or goodwill as compare to other leading producer, that’s why people worry to go with it BUT A089 Bolt really impress me, let me explain its spec: it have "4" inch with 1.3 GHz processor(Android 4.2.2) the main thing, is it have both side camera(480 x 800 pixels) and the battery management is also superb(2100mAH) capacity, and the price of that phone is just around R.s 4000 which means it have value for money.
I think in this price you will not get that much spec from any mobile manufacture.its worthy to buy it.and the best thing is Micromax is an Indian company.
