I purcahsed my first smartphone i.e Micromax Ninja A89 in March, 2013. Its really value for money product. Currently, I have this phone in working condition & i'm using continous from 2013 to till now.
All the necessary features are having in this device with Android OS, 4.0.4 ice cream sandwich, 512MB Ram, 2 GB internal storage. I was rooted this mobile in 2014 and make phone storage 8 GB, it reads SD card as a phone storage with rooted software.
I faced only one problem with phone i.e charging pin. Charging broken down so many times, but my friend repaired after it was working fine.
Conclusion: i'm fully satisfied. Now, its time of compitition, so many options are available to buy budget phone but in the past period of time only few options are available to buy budget phone. Thanks alot to micromax, they provide me budget phone.
