The iPhone 4, although tougher than the previous iPhone 3Gs, suffers from the same damage done by impact and accidental drops; smashed and broken front glasses. But what makes the iPhone 4 front glass so much more expensive to repair than the iPhone 3G and 3Gs?
Yes, being a new product the parts are still more expensive for repairers such as Sydney iPhone repair specialists Fix My iPhone (FMiP) but director of FMiP, Kevin Orchard, points out further issues with the iPhone 4. “Where as the 3G and 3Gs had a separate glass digitiser (touch component) and LCD the iPhone 4 returns to the same assembly type for the display as the 2G”. He further explains “Although there are kits that allow for replacement of the iPhone 4 glass without the LCD we offer these repairs with the complete assembly for a higher quality and longer lasting repair”.
To deal with some of the technicalities of the iPhone 4, the front glass is made of aluminosilicate glass which is basically normal glass combined with aluminium oxides to aid in scratch resistance and overall strength. While this does provide a solid result, with a good mix of strength and flexibility, it is not impervious to shattering or scratching. There were some rumours of the iPhone 4 using Gorilla Glass (which also breaks just ask some Dell Streak owners) but this is not the case. The LCD itself is also not a cheap component too, basically being a purpose built HD LCD. By gluing this front glass to the LCD itself basically means that both need replacing as a complete assembly, adding to the overall costs.
As time goes on it would be expected for iPhone 4 repairs to decrease however, as with the 2G, the more expensive part assembly will always result in a more expensive cost to consumers. Our advice? Get a good iPhone 4 cover, try to look after the phone, and always keep the phone away from any potential drop zones.
