Causes of cracks in a touchscreen
Many new mobile phones have touch screens. (Staying in Touch image by Kathy D from

Many of the newer models of mobile phones and mobile devices, such as iPhones and Android-model mobile phones and devices like the iPad or Kindle, have touch screens, allowing uses to simply touch the screen to interact with it. However, these touch screens are relatively sensitive and can be shattered or cracked in a number of ways. When this occurs, it can be very expensive to replace the touch screen so it is important to know how to keep this damage from occurring.

Dropping, throwing or sitting on the touch screen of a phone or mobile device can cause it to crack or shatter, rendering it useless or at least difficult to use. The earlier models of touch screen phones were particularly prone to this, as dropping them only a small distance could cause the screens to spider-web with cracks. While the newer models of these phones have stronger pieces of touch-screen glass, it is important to buy cases for the phones to ensure as much protection as possible from this type of damage.


A touch-screen phone in your pocket being pressed hard against something, such as a wall, a desk or a car door can cause it to crack. Having the phone in your pocket when you slip and fall on it can also cause it to break if it does not have a case. Having the phone in your backpack which is stepped on or thrown hard onto the floor can also cause it to break, as can keeping it in a checked bag on an aeroplane, which may have a number of other heavy bags piled on top of it. This is another reason buying a case for the phone is a good idea, as well as not putting it in situations where it will encounter large amounts of intense pressure.

Extreme Heat and Cold

Extreme heat and cold temperatures can cause the phone itself to contract and expand, possibly causing the touchscreen to crack and malfunction. While this is a rare scenario, as few people go from extreme heat to extreme cold with their touch-screen cell phones, it can happen in certain circumstances, such as someone who works in a laboratory walking out of a freezer into a heated room, or someone who is outside in subzero temperatures walking into a warm building.
