bowlesg, Mar 24, 2016 : Hi there, I was wondering if you could help. Before I begin my phone is rooted and is on Oxygen OS v2.2.1 (I flashed it a few days ago) Yesterday I installed the OpenVPN client for android, I had already been using CyberGhost with no problems and the OpenVPN app strangely wouldn't work. So I installed the 'OpenVPN for Android' app (another OpenVPN client) and that didn't work either however it gave me an error "VPN API permission dialog cancelled". I googled it and found that It is a fairly uncommon problem that mostly happens when ROMs dont have the VPNDialogs.apk installed in /system/priv-app. I looked and I found that in Oxygen OS it is installed. I then proceeded to install a Xposed module called "VPNDialog" but this did nothing. After reinstalling CyberGhost (which was working fine before) it is now not working and just glitches between the greeting screen and the "fetching server" screen. Edit: Just to add, the Screen that asks you if you trust the vpn doesn't apear and if it does its only for less than a second. Help is much apreciated. Thanks in advance.
