Hi totalkaos2 here
I have a oppo f1s that if set a theme that changes the lock screen look and when I went to go for a different look it git stuck and no matter what I try won't go away iv tried:
SD protection ( oppo f1s does not have this option)
Reapply the theme then removing or changing it
Updating the phone to v 3.0.0.0i
(latest version as of the 19/3/2017)
If anybody know how to fix this please do tell me I am not the only person experiencing this problem
