Android: The inactive check box 'Trust this app' on an Android device

Please try to install the standalone version of the VPN Unlimited app from our web site. Also, sometimes this issue could be caused by another app installed on your device. Try to close other apps one by one, and then mark the check box again. Some of our customers with the same issue reported the following: “I downloaded the CM Security Antivirus and it found the TowelRoot. I fixed it and now the VPN is working.” and “On my Nexus, I deleted 2 meteo apps. And now I can mark the check box and use the VPN Unlimited app.” Please let us know if it works for you too. If not, feel free to contact us.
