We've had several reports from Nexus 4 users that they have to double swipe to answer phone calls when Rocket Player is running. What has been stumping me is that our Nexus 4 with the exact same build couldn't reproduce this issue. However, customer Alan Green finally figured this one out. The issue is with an app called Contacts+. Once I installed Contacts+, I was able to reproduce the issue in Rocket Player and four other music players, including Play Music, so I'm sure the issue is with Contacts+. That being said, we've not had any reports of this issue on other devices, so unless you are on a Nexus 4 running 4.3, don't worry too much about this post. :-)
