It is now January 1st, 2020. This is still an issue. My phone started doing this yesterday. After having this phone for about 7 months or so. I've had the same settings since then. Been using everything I use now. And still, this problem randomly happened. Why is this problem still persisting with everybody here? Why is it so random? Why is there no patch? Come on samsung.
Mine had this problem months ago and turning off the fingerprint sensor for unlock worked. I ran into a whole new problem with it after ATT updated to Android 10. Forced my phone into a boot loop. Would not work in anything other than safe mode. I took it to UIbreakifix and they pushed it back to android 9 for me. now it works again as long as I keep the fingerprint sensor off. What happens when ATT makes me update it eventually?
This happens to me too. I went so long without it happening. Reset my phone to factory today and it stopped all day, as soon as I enabled fingerprints later on, it shut off.
Come in Samsung this is embarrassing for a phone this expensive. First i had the sticky camera, got that fixed, now my warranty is expired and this phone still cost almost $1000 and it's barely over a year old. My s5 lasted me 4 years with no hiccups.
