Hello, my son has a nexus 4. He sometimes looks at things through our family filter that we would not allow because the program (dansguardian) does not work on his device. It works on all of our other PC's, iphone, windows phone, and nexus 7. Is there a specific problem with the nexus 4 that will not let it work with this program? Our router is a customized PC, and has Linux running on it. The program is installed there. The nexus 4 and nexus 7 both have android 4.4.2 running on them. Any help will be appreciated!
