Can someone suggest the best phone for camera, games and better to use apps? and for customise?
You cannot expect all the best specification in one mobile phone. Each mobile phone has its own drawback.
Iphone is best for camera, games and apps to use but its not customizable, some mobile has all good features except battery life and camera.
As far as i know Iphone X and Samsung galaxy note is really good if you are not on your budget.
There are so many apps available to customise the phone, you dont need to check for the feature within the mobile. When it comes to clarity and working HTC U11 is good..
Samsung Galaxy S9 is really good with all the best features and it provides the best user friendly experience
