My friend has an iPhone 6S and yesterday she contacted me telling me that she can't flick from left to right or use many of the basic gestures with voiceover. She said she took her phone into the bathroom with her and set it on the counter while she took a nice hot shower. When she was finished, she took a call but her hands were dry according to her. After that, she couldn't use any of the navigation gestures on her iPhone. She said that she can't even answer a call with the 2 finger double tap, voiceover does nothing. She said in order for her to navigate with flick left or right, she has to place her finger at the bottom of the screne in order to perform these gestures. She can't put her finger anywhere else on the screne otherwise VO won't speak what is under her finger. She has an otterbox case with a screne protector built in. Also, when she uses hey siri and her phone is locked and she asks siri to read her messages, it says you'll need to unlock your iPhone first. Anyone know how to fix this? It didn't use to do this before. Any help with these issues would be greatly appreciated. She's running iOS 12.4.
