maybe you need to reinstall your current rom stock or custom some time it hangs not the nexus 4 but all phones and as u said that it re-worked again so it's probable a Software issue
install franco kernel , it increases touchscreen sensitivity to the most that it can get , if that doesnt work , yeah get a replacement.
MAKE SURE YOU FLASH A STOCK IMAGE AND RELOCK YOUR BASEBAND BEFORE YOU RETURN THE PHONE !

Unusual touch screen issue - delayed on start up?

My LG Optimus 7 touchscreen stopped to response with no reason. Nothing was installed or damaged - one minute I called and after turn off and on it stopped to respond. Well - not really stopped but respond in strange way not allowing me to unlock (swipe) lock screen:

(I took this video after Factory Reset which did not help - that's why it's in German)
And even if I reboot it, no buttons tapping is working, nothing - only this strange unlock screen which moves really slowly and not allowing to unlock.
I ordered and replaced digitiser (dismounted all telephone myself) and this did not help at all.
But I realised yesterday that if I leave my LG with screen open for 2-3 minutes IT STARTS WORKING!! It reacts on touch as it was before! No idea why and how. Unfortunately it goes into unresponsive mode after turning screen off and on, and I have to wait again. So it's useless...
I tried to google and I found few other people experiencing the same issue with different telephones (or tablets). Does it mean it's hardware issue? Is there any point to downgrage ROM - at the moment it's 7.10.8862.144??
