I have used Micromax canvas hd a 116 for 2 years. From 2013-2015. Faced no problems especially regarding hanging.
No issues even after having Only 1 gb ram. Camera quality WAs not appreciable but the ppi ( pixels per inch) is 294 which is quite amazing in its range. Moreover I was attracted by design which quite cool and curvy. Looks great in hand and is very reliable. Yes I agree internal memory was not enough and the worst thing about this phone is its battery backup.
