I don’t trust galaxy M40.it is hanging in 1st month . battery backup is average but gaming quality is very low . bad camera quality comparison to other range of this phone .cheapest graphics used in games and dont play well games like pubg and all expand games .its size is so big dont have to handle it properly look is average from backside it is very poor and very bad experience to using it .dont buy it because of samsung it has nothing positive point except type c charger.
