i am trying to configure a VPN on my Android (v5.0) phone. i can successfully create the VPN via SETTINGS | MORE NETWORKS | VPN | BASIC VPN, and all works fine. i can connect and disconnect as needed. however, if at some point i disable the screen lock on my phone, the VPN is deleted and in order to use it i have to re-create it from scratch. this makes no sense to me. why should the use of a VPN be dependent on having screen lock enabled? and more importantly, why is my VPN configuration being deleted when i happen to turn screen lock off? is there anyway around this? am i doing something wrong????
