Same issue here. Started about a week after I got the phone and only a reboot fixes it. It usually is only once every day or two but it happened 2 times in 15 mins of each other today.
I haven't been having this issue too much... But I'm afraid it will get worse like some of yours. I contacted support and they gave no info about an update. The people who say it's coming on the next patch... Can u link a source?
For right now disabling FP gestures solves the problem but you lose half the functionality of the FPS
This totally solved the issue for me. I've been able to unlock the phone ever since I turned the fingerprint gestures off.
Thanks for helping out!
Same issue here. Had this S8 plus for about a month and this happens about every 2 days or so. Going into "system apps", "fingerprint" to try to force stop doesn't work as it's greyed out. This is so annoying. Of course restarting the phone works to clear it, but for one of the main functions of the highest end phone ever made... FAIL Samsung. Really hoping a software update fixes this, but being on Verizon I'll maybe expect a fix in 6-10 months. Of course the Verizon store's fix was to just keep restarting it, or switch to using Iris scanner (which I've heard works WONDERFULLY!!-sarcasm.. ), or replace this brand new phone with a refurbished one. Seriously.. WTF??
I made the switch from HTCs from the M7-M9. Seriously considering selling this thing and going back to HTC.
