Robert Matthews, physicist and visiting professor at Aston University, can prove why it is so. He says that the way a smartphone falls is governed by the same laws of science that causes toast to land butter side down. He has even developed an equation to prove the phenomenon.

According to him, we usually hold our handsets loosely with our fingers below the centre of gravity. This causes the handsets to drop off or pivot about our fingers. But once we lose them completely, they follow a trajectory that's dictated by the forces of science on them. Such a trajectory allows them to fall face down, thus shattering or cracking up their displays. The following formula explains the trajectory:
L = length of the smartphoneg = acceleration due to gravityp = 2δ/L = “overhang parameter”δ = overhang distanceθ = angle of the smartphone when it starts its descent.
“People might think it’s just their bad luck when a fumbled phone lands screen-down and smashes. In fact, physics is to blame, making screen-down landings more likely. It seems we’re all at risk of experiencing this manifestation of Murphy’s Law*: “If something can go wrong, chances are it will”. People who are naturally clumsy and often fumble their phones are clearly particularly at risk,” says Professor Matthews.
Smartphone screens that last a week? Very soon, say scientists
Since there's no way we can contradict science, the only other way out is to develop such screens that just won't crack no matter how strong the impact is. Motorola has led the way with its new Moto X Force smartphone.

Moto X Force wields a 5.4-inch Moto ShatterShield display which is basically a Quad HD display shielded by five layers that can absorb shocks and heavy impacts. The presence of two touchscreen layers also ensures that you can continue using the touchscreen even if the outer layer cracks.

Thanks to the ShatterShield technology, Motorola is even offering a four-year warranty against any damage to the display. We wonder if any other phone maker has such confidence on the invincibility of its handset displays.
