Recently I bought this phone Micromax canvas xpress 4G. It is a good budget phone priced at only 7000 rs. It has 13MP rear and 5MP front camera. It has 3GB RAM that prevents it from hanging. It supports 4G, 3G and 2G network. It has a good battery of 2500 mAh that lasts long for about 2 days of usage. It has good sound quality and powerful performance. It works on an android 5.0 that is lollipop and 2.5 ghz processor. All this makes it a good budget smartphone.
