I'm relaxing in the hot tub and decide to ask Siri to set the timer. Works fine. After awhile, I try to ask Siri how much time is left, but before I can finish the question, the screen goes blank. I tried it several times, asking different questions and giving different directions, but Siri only worked about 15% or the time, or the screen would blank out. When I take it out of the Zip Lock, it works fine. Now all other functions work fine in the bag. Including making a call. I would think that maybe Siri couldn't hear me right, but the screen would just go blank mid-sentience. That doesn't happen when Siri can't hear you clearly. It not a big deal as the phone is working fine otherwise. But I find this interesting.
