I just started having this same problem. Did the factory reset and everything. Phone was fine after the reset until I did the fingerprints for unlock setting. Phone only turns off once I lock the phone and let it sit idle. Usually happens in my pocket.
My phone, s9 plus works well when using fingerprint, pattern, face recognition. Oy the problem is that when I go into the settings to add or delete a fingerprint, my phone hang and shut down until dead battery. What should I do? I've done restarting my phone, and such. Hope you can help me with this. Thank you very much
I was hoping I wasn't the only one.
I have the same issue too only my phone turns off whenever I try to use the fingerprint sensor be it registering fingerprints, trying to access samsung pass, or just plain enabling fingerprint unlock.
I've used the hardware test on the phone by dialing *#0*# and under sensors you can select fingerprint sensor. Sometimes this test works but most of the time if just turns off the phone.
I've taken it to an authorized service center and they couldn't do anything about it. They tried to reset the phone but they said the phone wouldn't accept the binary files they were using.
I've gotten by so far by disabling fingerprints all together. The phone will sometimes turn off but it's lets frequent.
My phone turns off randomly when I use fingerprints as security. I don't need to restart the phone. I have already gone into safe mode after a factory reset and the problem still persists. I have already sent it to a warranty repair center but the problem still persists. I was told it was going to be fixed but here I am.
I'm sorry to hear that. Try logging completely out of your Samsung account, power cycling, and then logging back in. Let us know if this helps.
If all troubleshooting steps have failed, you may need service repairs. I understand you have submitted your phone for repair once before. I would be glad to look into that service and set up another service for you. If you wish to move forward with service repair please send a private message to http://bit.ly/2JH2rq2.
