Difference Between Jelly Bean and KitKat


Main Difference

Android is a software which runs on cell phones which use Google’s operating system. It has a different coding and applications which are only compatible with the mobile phones which are using the platform. Initially, there were two separate types of software which ran on tablets and phones, but now they have been combined together to work on one platform. Ever since the emergence of Android, there have been upgrades such as apple pie, cupcake, éclair, gingerbread and moving on to Jelly Bean and KitKat. The former one is the advanced version of the initial one, and there are few differences between them which can be considered as improvements on the previous version. Very basic changes that the user will be able to notice include changes in color. People are able to view different colors such as white in KitKat instead of the usual blue which used to dominate the interface in Jelly Bean. The user experience of KitKat is much better too, and people can easy switch between screens in the new version. In Jelly Bean, it is hard to view some applications on the full display, but that issue has been resolved in KitKat, and all the apps can be seen in the full mode. There is a marked difference between the designs of both platforms too, in KitKat the design feels simpler in comparison. Although the design also depends on the cell phone being used, few differences in that regard depend on the different cell phone providers. Another change between the two software is the clock style. Jelly Bean watch size was much different while KitKat the clock font is thinner. There are also differences in the performance and once the upgrade is made from Jelly Bean the phone gives a brighter look and a new feel. One important change that has been brought is that people will be able to use cell phones with 512 MB RAM, which was not possible in the previous version because of the limit of 1GB RAM. The applications start faster in KitKat as compared to Jelly Bean, and the speed increases almost 25%. Overall there are significant changes between the two and further explanation on these two software upgrades is given below.
