I've been having this problem for a day now. The whole day I've tried everything to fix this stupid issue and I'm sick of it. I've deleted, downloaded, replaced, renewed every single thing I could do. I did a Factory reset. I did safe mode, I did hard reset, soft reset, called LG services, went to stores (all said to wait it out, but I'm to stubborn to let it go untill I have a proper good answer instead of a sorry and a money related solution) really everything and I can't get it to freaking work! It's making me nuts! Oh and... I've had this phone for barely a week now, to make it worse. Okay, rant over. Let me explain... Last night I've had a software-update and at first, everything was fine. I went doing my own thing when all off the sudden, my finger wasn't able to scan. When I went to settings, the whole bloody "fingerprint" option was gone! After that, I went on the roller coaster you see above. According to the helpdesk of the netherlands LG I'm the first to have this problem, but the internet says otherwise. And I hope someone can help me please. Thank you for letting me steam a little out and I'm sorry for my frustrating message.
