This case is not a fake. I am missing the pulce meator. In accessories it is not an option .. It worked great for over 6 Mos. and just stopped .. Thinks

Are you talking about measuring heart rate using S-Health?

That should work regardless of the case itself . . I just pulled my S-View case off of the phone and took a heart rate measurement in S-Health without a back cover. Worked just fine.

Probably should go through the standard troubleshooting steps . . . reboot .. recheck . . reboot into recovery and clear cache . . reboot and recheck . . All else fails, backup everything and factory reset.
