its the same..., except rear camera set up (M31-4 cameras, F41- 3 Cameras) both are same.. , I advice not to go for F41..., new device F41 released on October is still running on October security patch....,
m31 has good display, but f41 has display with issues, my issue started just after 1 month, slight white lines can be seen at the right side of the panel when looked closely
