I bought the micromax bolt s301 phone last year .its a good phone with android 4.2 kitkat. with a earphone and charger, it is a low budget good phone. one should buy this phone. but when it memory gets full, it starts to hang, some times its dont responds . but when it has more of free ram it works great . one can play a lots of games without getting hang the set . the micromax company had maintained a good quality. but unfortunately micromax is trusted by a very few population
