when I upgraded to the s I was delighted that the fingerprint sensor problem from from the 6+ seemed to have been solved. Now after only a few months it's practically unusable again. I'll clean the sensor off only to have it work a few more times before not working again. Frustrating to say that least. When will this tease be acknowledged? I'm still on 9.0.1 and have been waiting for the kinks to get ironed out before updating as I've heard there's a problem with the alarm clock in 9.2 now. Will updating help the fingerprint issue?
