Samsung galaxy j7 prime( new) It comes with 1.6 ghz octa core processor and 32 GB of internal memory.Since 3 months I am using it. It is quit well but I found the front camera quality is not so enough so you can not shoot in HD qaulity.
Finger print lock is a good feature for security reasons.
Speed is to good as it has 3 GB of ram. Never hanging problem I faced till date.Recommded product with brand loyalty in 19000 of price.
