There are many types of phone mostly people like Samsung company mobiles but the mobile which has the grace and can motivate me is iPhone it's the best mobile for me 
iPhone is expensive but the functions in it are very good the thing that I not like in the iPhone is that it didn't accept any thing you can't share app but it has its own App Store and an iTunes Store in which we can download any app or file or songs well Samsung company mobiles are also very awesome but the main problem with Samsung is that it's battery capacity is not good and it's memory is much but it begin to bling in 20 or 40 percent battery however the style of Samsung is nice but is great
