My first phone was Samsung Galaxy J5 prime.. an entry level midrange smartphone and that's 2 years ago and upto till date I'm using that same phone nevertheless i never faced any issues like over heating, lag, build quality issues.
So i must say that Samsung phones are built well and i admire the company's dedication towards it's consumers as Samsung provide every basic feature in their phones from mid-range to flagship(*cough don't remove headphone jack)
