Micromax A177 mobile phone is not so good.its battery backup is best because it is a 3000mah battery. 5.5inch display and 1GB ram budget phn is very bad.More time it hangs regularly.and this phone have most software problem. Almost the service of this phone is very very Disgusting. Display and camera quality is also bad. Its a heavy weighty phone but it looks very well.its price is nearabout 7000 to 9000. From my personal using experience I can said that, from the different side this phone is not so best budget phone.Thank you
