I brought samsung galaxy j7 , a 6.0.1 version. I have been operating it from last year and guess what I had no use of warranty card. It worked well. For 6 months the battery pickup was just awesome. However with time it starts fading. Ram corresponds to 1.5 GB and internal storage is 16 GB. Howver last week I had to take to repair cause the ic was short. Well it did at the cost of 250 INR. Camera is good bt for sake don’t compare it with mi phones. The applications are way too exciting. And dimension of phone is pretty good.If u get the information useful do put a thumbs up.
