Since yesterday all Android Devices users get ICS fever, some of them also wonder if their smartphone or tablet are able to run with Android 4.0 update such as Galaxy Nexus which has superb hardware. You might heard from another source that you should not worry if your devices will meet minimum hardware requirements to run Android 4.0 Ice Cream Sandwich update as Google stated that it will be run on all android device. You should know, “run all on devices” mean this update is designed to operate with tablet or smartphone, whatever the screen size is.
Head Moderator of CyanogenMod forum also said that there’s two basic requirements to run Ice Cream Sandwich update smoothly, all android devices must have 256 MB RAM or more and also decent GPU since Hardware-accelerated 2D drawing might be needed, 2D acceleration depends on your phone GPU not the CPU so, there’s no problem if your smartphone still powered with ARMv6. I think only middle and high-end phone meet that criteria. But if your phone doesn’t meet those, it doesn’t mean you will never has chance to install it, CyanogenMod Team with CM9 and another developers will work hard to make it work on all android phone. While wait you can try the launcher or theme based on SDK.
