I really hope they remove that annoying Moisture in Connector popup that I have to dismiss twice before I can access my phone EVERY TIME i plug in my phone. I have had this issue ever since I update to Beta 3, and I am assured there is no actual moisture in my lightning port, I have done the rice and hairdryer trick even though I never take my phone into the bathroom and have never exposed it to water, plus it's a 6s+ with a case on it, so I'm not sure if I'm the only one having a faulty sensor or if this is a common occurrence.
Downloading beta 4 as we speak, looking forward to seeing MacRumor's (typically fast) video on what's new in this beta today.
