Thanks to the hard work of very talented developers over at the XDA-Developers community, the LG Nexus 4 has received Android 5.0 Lollipop earlier than Google is rolling it out officially. In addition, you can now get all of the Google apps with the updated looks on your own phone.
However, only rooted users may apply and the apps won't work on all smartphones. Currently, the latest Material Design Google apps that are available as downloadable .apk files include Play Music, Play Books, Keep, Calendar, Gmail, Drive, Maps, Messenger and Fit.
Before downloading and flashing, make sure that you're smartphone has root permissions and that you've read the source link Topic.
