Very good selling mobile brand is Samsung in India from long time, the company designed their own mobile OS for this mobile. There is no play store in this mobile, Tizen storie is there for Apps downloading. But minimum apps available in this store. I had helped to my friend for purchasing this phone from my syTstem. I saw this mobile nice for carrying, while it is compatible in one hand, He is using BSNL network, so big trouble for getting BSNL settings, then he was inserted Jio sim in sim 1 slot, signal getting slow. Phone is good for simple user(who had poor knowledge in technology using). It is coming 1 GB Ram and 8 GB Storage, front and back camera for normal usage. But in this price range Redmi 5A is more better than this model, more features in just 4999/- in Flipkart. 10.or D is one of the best around this price range, it is available in Amazon store.
