The January 2104 MC319z BPS 4.41.04 posted to support is only an update to support the new display hardware. It contains an older version of Fusion Fusion_3.00.2.0.019R. Most WEH653 devices have updated to Fusion Fusion_3.00.2.0.025R hotfix. I suggest applying that Fusion to your MC319z devices. You can find the 25R patch under the MC9190 or MC75A0 support portals.
