I have finally managed to install the ubuntu touch on my nexus 4. Now the problem is its very Laggy. I have installed the "trusty" latest channel and its quite messy. Change background is not working. Dialer is really slow and everything is messed up. But I have seen many videos of nexus 4 and everything is working smoothly. So do I have to change to or pick any specific channel for installation? Please tell me is their any stable and properly working channel which I should choose for installation or what should I do?
Even tough I have installed Ubuntu touch from "trusty" channel on my Nexus 4 (version 303 which is the version I got two days after the final release of trusty 14.04) and it is working good enough (much better than alpha and beta), this should be a stable version.
If you have a lower version than "trusty" 303 you must absolutely update your system. otherwise try the "utopic" channel as suggested by the wiki page.
