One of the reasons for that is the phone manufacturers just love to mess around with it, chopping and changing the menus and features about, and that takes ages to get right. It also means it takes forever to issue an update to the software when Google changes it.
Unlike HTC, which has messed around with Ice Cream Sandwich to the nth degree, LG has taken a different approach, making only the smallest of changes. It says this will make the process of issuing updates much faster than it was with last year's phones.
But what changes have been made, I hear you ask? Watch the video above and all will be revealed. Oh, and do let me know what you think in the comments below or on our Facebook wall. Ta.
