I had been using Micromax Doodle Canvas 4 for the past 3 years.It is very unique from other phones with its size.It is about 15cms in length.It is a very good phone.It provides highest resolution camera, high storage capacity, high battery capacity and I had been using it since 2015 I had never encountered any software issues till now except a small button problem.when I bought the phone it costs 9999 rupees.It was very cost effective.I aways prefer MIcromax phones.
