Marks on front camera photos

[Akrob]

Hi, I have a weird black line and various dots and other marks on any photos taken with my front facing camera. I can't see any cracks when I look at the camera. The marks only just appeared after months of normal appearance. Any ideas what they are and whether the problem will be covered by warranty?

Welcome to Android Central.

It looks like indeed like some debris has arrived inside the lens glass. I would at least inquire about a warranty replacement.

If warranty replacement doesn't work out, you can try cleaning the debris yourself, using this video as a guide to opening the Nexus 4 case and accessing the camera module. It doesn't llok to be terribly difficult.
