Karbonn brand is popular for its ads but only a user can say exactly how worst the experience is. This 5 inch mobile is just supported HD with 13-Ultrapixel rear camera which should not be good for video recording or else working. The 8mp front camera is comparable with a 2mp camera of Sony mobiles. It has 1.3 GHz quad core processor which is as bad as it hears. There is 2 GB of RAM what says that users should avoid gaming.
But the most disappointing thing in this mobile is the combination of 2GB RAM and Nougat facility with 16GB of internal memory. Only the nougat system will consume the 1.1 GB of RAM and Google Play Apps and other processing apps will take atleast 500 MB of RAM. So users will get less than 300 MB RAM for use with which the Google chrome app even lags. Even the mobile is 4G using 4G will let the mobile hang frequently. So it will be a lagful experience.
So in this generation there is no use of such mobiles with is kind of features from a brand like Karbonn which has no good service. If someone got money problem then there is a lot of options provided by Redmi. So there is a conclusion comes that in any situation buyers should avoid this kind of phones and its my personal recommendation.
