Ever since the last update, I was not able to use my fingerprint scanner properly anymore. At first I thought the problem was my fingers being too sweaty but after letting my sister try it, it still do not work most of the time. I had tried restarting, safe mode and removing and inputting my prints again and again, still doesn't work. Also, since the update, a message in my lockscreen saying "Make sure the home key is clean dry..." keeps appearing oncein a while. This all happened since the last update, it's been a month now and I'm getting irritated. Please help me! If only I can undo the update!
