When I receive an incoming call on my nexus and I swipe to answer, it hangs up instead of answering. This has been happening for the past month. Use to do it once in a while, but lately it's been every call. Is there a way to fix this?
If you haven't yet, back up your phone and then do a complete factory reset. It seems like the issue you are having is software. I believe this will fix the problem. (Have had something similar happen to me on a different device).
