as might be expected back on top case of Spigen, top processing as it did in my previous Handy`s rating of 2.3 and now 4, but the notch on the sensor (with the camera) is somewhat scarce that one sensor with slender fingers poorly achieved and this is not the example. Can measure pulse !! I've just the bridge between Camera and sensor finely cut out and now everything is working as it should. While this is a possibility should there rework Spigen or omit the bridge !!!!
