There is a tendency to buy phones with big screens, without caring for the problems a big screen can bring along with it.
If you have money and you really need a big mobile (e.g. you need to watch videos/movies or read a lot of matter or compose documents), buy a big one by all means. In fact, you can go for a cross between phone and tablet (fablet), which is quite a bulky phone but has screen as big as a tablet (9-10 inch). However, don't buy a huge mobile only as a show off.
- Big mobiles need to be held in hand or kept in a clutch as these cannot be kept in shirt or jeans pockets.
- Big mobiles will, as compared to its smaller sibling, likely use more battery.
- Big mobiles are also prone to suffer bigger damage on fall.
- Phones wider than 3 inches could hurt your palm, especially if you have small hands.3" width would correspond to about what is called 5" screen size.
