After upgrating to 5.2.3.0 by fly, VPN didn't work, connected and dissconnected immediately, then I upgraded from file update.zip, VPN start work, but .... it disconnected after sometime, usually 3-4 min.
No matter the type of VPN, with any type of VPN same problem.
How I can solve this problem? May be someone can check in his device. I didn't wipe(clear data) when upgraded phone, may be after wipe it will work fine.... But, I must know it before Clear All Data. Does that make sense?
