Samsung does not have that much of reputation in the market that other brands have. It is because of their own product. If we talking about J7 the phone is overpriced and also under powered. If I spending almost 16000 rs so why I will buy this phone I can have much better phone than samsung j7. Samsung is giving snapdragon processor but the processors are not good enough for this price they have also given snapdragon processor in this phone but the processor is not good enough.
They are providing only 2GB of RAM and 16 GB of internal memory which is very less. No ambient sensor is given so we have to change the brightness manually. If we talking about display only HD screen is given in this phone. SO Led notification is not given so we have to check every time whether there is some notification or not. Samsung doesnot provide fast charging facility and probably we dont get an android update on this phone. So I personally feel that we can get very good phone in this price range than j7.
