The PACman ROM can be said to be a hybrid ROM. It combines the features of the three bigwigs among ROMs in the Android community: the Paranoid Android (PA), the Android Open Kang Project (AOKP) and the CyanogenMod (CM) ROMs. This is a huge benefit for users as they can experience the features of these various ROMs at the same time instead of having to choose either of them.
The Nexus 4 originally came with Android 4.2 but later an Android 4.3 update was made available for it. This PACman ROM that we are about to install also provides Android 4.3 with it. It contains all the features of Paranoid Android and CyanogenMod ROMs and some features of the AOKP ROM. It provides the users to choose from Phone UI, Tablet UI or the Phablet UI as per their need.
