Samsung best budget phone is Samsung Galaxy J7 Its sound is not so loud but best for headphones. This device is not so expensive and good for budget phone users and because it has all the specifications that a normal or middle-class person need Its design is not good for 2017 because nowadays there is a trend of bezel-less phones extremely no bezel. like xiaomi mi mix and mi, mix 2. and also like s8 and note 8. I will recommend this phone for daily use but not for business use.
