    # LP camera hal has a reference to libion.so, although it is not using it.
    # libexynoscamera.so wants to use ion_alloc()/... of libion_exynos.so but as 
    # libion.so (with the functions of the same name) is already referenced,
    # the functions of libion.so are erroneously used instead of the libion_exynos.so ones.
    # This causes crashes whenever the camera is used (in ion_alloc).
    # Solution: replace libion.so with liblog.so which is already referenced by the lib (-> no-op)
