I have an iPhone 5s and am using latest iOS version (11.2.2 I think). I am having problems changing from ear speaker to loud speaker whilst using voiceover. Normally, I use ear speaker for phone calls but, occasionally, I want to share a call with someone or use loud speaker when accessing voicemail as it is easier to use the keypad with the phone held horizontally.
Moving the phone to a horizontal position doesn't seem to activate the loud speaker easily. I have tried all types of rotation, fast and slow, to 'encourage' loud speaker activation. Eventually, loud speaker does happen but usually after a lot of furious phone movements. It could be a voiceover bug or some other glitch and was wondering if anyone had any thoughts on this problem. Any ideas on a precise movement or exaggerated movement I could do to move from ear speaker more consistently? Phone settings I should check?
