Value for money phone. Review on Micromax A093 Canvas Fire

I am using micro-max canvas a093 for last 9 months and the phone is still in great condition.the touch is as smooth as new. the processor got a bit slow but that is what you except from phone of this budget range. the sound quality is loud and clear. the phone come with two gsm sim slots with 2g and 3g support.the android os is kitkat 4.4.2 but there is no lollipop update from micro-max.the processor is Quad-core 1.3 GHz which is awesome on paper but with ram 0f 512 mb of which only 400 mb is usable you can only play high 2d or low 3d games.playing high 3d games(asphalt etc) cause phone to hang and then close the app.internal memory is 4 gb of which 2.5 is used for storage while other is used for apps and android.the phone has a heating problem.looks of the phone are okay.camera quality is low despite being 5 mega pixel.all an all a good budget phone but after sale service of micromax sucks. after six month of use volume button stops working I give it to customer service they return it after one month. so if you can deal with micro-max care and are low on budget then I definitely recommend this phone.
