iPhone Repair Company Claims iPhone 4 Screen Not Immune To Cracks

iPhone 4 glass not strong

By now, you may have read several reviews of Apple's latest iPhone model. One of the biggest talking points about iPhone 4 is the material used for the glass panel. Apple has noted that the screen is made of aluminosilicate glass, which is the same type of material used in the windshields of helicopters and high speed trains.

These panels are said to be 20 times stiffer and 30 times harder than plastic, which makes the glass virtually unbreakable and scratch-proof.

However, folks at iPhone repair services company iFixyouri, differ in their assessment. The firm claims to have received their first set of iPhone 4 replacement parts recently and note from a preliminary test that the iPhone 4 glass panel may not be as strong as one may have thought.

For the test, iFixyouri studied the response of the aluminosilicate glass to shock and sudden impact. This was done by dropping an assembled iPhone 4 unit (without the internal circuitry elements) from a height of 3.5 feet on a flat, concrete floor. The firm notes that the glass on iPhone 4 cracked in just three such flat drops. A second trial on a softer carpet floor got the screen cracked by the seventh drop.

It may be noted that the iPhone 4 unit used for the test did not contain the internal components. It is hence likely that the relatively hollow nature of the unit may have accelerated the damage caused. iFixyouri however blames the vulnerability on a flaw in the design of iPhone 4 rather than the glass material itself. The firm notes that the glass panel on iPhone 4 "sits" on top of the aluminium frame, which makes it much more vulnerable to accidental drops. In comparison, the glass on iPhone 3GS is recessed and protected by a chrome bezel, which helps to better overcome the impact from a fall.

It is not clear whether the aluminosilicate glass panel on iPhone 4 is a better alternative than the Gorilla Glass technology used on rival devices like Motorola Droid. Until a comprehensive study on the same is conducted, we will have to take the results from this study with a grain of salt. It's also possible that the iPhone 4 replacement parts that iFixyouri received is fake. 

It's also hard to believe that Apple who has been working on the iPhone 4 for the last 2 years, wouldn't have carried out even more extensive tests to find out the durability of the material used in the iPhone screen before making those claims.
