Hello guyzz... you can perform a simple trick described below to Enable Lock screen rotation. To do this ROOT is required.
1. Open the file manager on your Android device
which supports root file system access. I prefer Root Explorer.
2. Navigate to the following folder:
/system
3. There you will find a file named build.prop. You
need to edit it, so open it in your favorite text
editor. Again, I will use the built-in editor of the
Total Commander app, as it is powerful and
supports many useful features.
4. Add the following line to your build.prop file:
lockscreen.rot_override=true
Tip: Before you add the line, check if the same
parameter is present in the build.prop file, but with
the value set to false. If it is present, then modify
the existing line and set it to true.
That's it. Now reboot you device. The lock screen will
respect the gravity sensor right after reboot.
