I developing a DeviceManager sample app,and i use resetPassword() method to reset screen lock password. using some long length password,just like "123456"、"abcdef",this method result tells succeeded,and working good on screen lock.
using some short length password,"11" or "ab",the method result still succeeded,but not working on screen lock. and strangely,when i input wrong password,some screen text show that is wrong password,then input correct password,it doesn't show any text,just no response.
for this problem,i have restored factory defaults three times。
