Android 4.0 does not set the boot lock to use vpn

You do not need to add any security settings when setting a vpn on IOS. In earlier android versions, 2. x is not required. However, after Android4.0, some security facilities have to be set up for vpn settings. This is very troublesome. I have been looking for a method to remove this troublesome item. I have asked many Android heroes and I have not found a solution. Some real masters even suggested that I modify the ROM, which is beyond my technical level. Finally to the Q & A Community http://v2ex.com to ask, got a very alternative solution. 1. Select the graphic to unlock when setting the vpn. 2. Test the settings. 3. When unlocking a graphic, use five wrong patterns consecutively. 4. The system prompts that it takes 30 seconds to try again. 5. Select the forgotten image. 6. Enter the Google account used to manage the mobile phone. (If you do not have a Google account or do not know what a Google account is, do not use this method. Otherwise, you will be responsible for the consequences ). 7. Go to the Security Settings page. 8. Press the home Key to exit directly. 9. The graphic screen lock has been canceled. The configured vpn can still be used. Do not adjust the vpn settings any more. This is why we should test the settings first. This should be regarded as a small bug in the android system. The solution is indeed an alternative, but it is also a solution.
