This is the one of the best phone in my view because I am vivo v5s user.This is a money value product.I using this product for one year.The front cam and back cam clarity is better.No hanging problem, no heating problem, no software problem.But little problem in battery backup.It has 3000mAh li-ion battery.The major problem of this phone is heavy weight.I think it may 150g.The desing of this phone is good.The finger print sensor placed the front center.It is note a butten.The sound clarity is good.And display resalution is better.In my opinion this is a nice product.
