Facetime video looking like a negative
When my mother is on a FaceTime call with me, my picture on her iPad looks like it is a negative, which she finds distressing (she's 91 and a dementia sufferer). I have not changed any of the settings on my phone/iPad and the same thing sometimes happens when she calls my sister.
Is there any way that she can easily correct this while on a call to us - or is there some setting on her device that we can change to stop it ever happening?
