I disagree bro, there is no hanging issues with new Samsung budget 4G phones, J series is one of the best budget and value for money phone. You can get good quality camera, optimised software, few months android security patches too. Dual 4G SIM card support. AMOLED Display. What more needed?
You can go for Samsung if you want after sales service and warrenty covering. Chinese and online brands are very bad in that, once you dropped the phone and display/screen gone kaput then no one can save the smartphone. The lifetime of the phone can go from 1 day to 5 year, but no gurantee.
Samsung phone i would suggest in this price range, you can choose any one of them according to specs:
Those are selling illegally and not authorised to sell, also no warranty covered by this. So it will be good deal only if 2-3k discount given by seller.
