Today I am going to tell you how to choose what type of smartphone, either it is premium phone or budget phone.
So first of all decide Os ( operating system) either it is ios or android. ios is easier to use but android gives you more choice. Ios is expensive than android or less choice or not customizeable, but in android you can customize everything.
Ios has more security than android.
Choose between premium phone or budget phones: in premium phone the iphone is in first rank, premium phone are expensive but having advanced feature like good camera, iris scanner which is in samsung s8.
Whereas budget phone are not so expensive or having average functions in budget phone you will choose Mi phones.
Speciality of phone: check what is special in this phone and then buy like oneplus 5 is special in camera or Samsung s8 is special in screen or mi phones is special for their battery performance.
Please, Ignore the camera pixel abd concentrate on aperture size( lower no. Is better) .
Thanx for reading my opinion.
