[Q] Settings button disappeared

view story

http://forum.xda-developers.com – Hey guys, I played around a bit with my framework-res.apk and removed the navigation bar. (bools.XML navigationbar =false) I have a nexus 10 with jellybean 4.2.1. Now Skype and youtube for example dont show the settings button anymore. (The three little dots above each other in upper right corner) Probably someone knows a solution to this. I would really appreciate it. (HowTos)
