I have a 3.5 mm aux cable that works with my wife's iPhone or iPhones in general but will not work with my Sony android phone/s. Also won't work on my mates Samsung galaxy S what ever number it is lol.
I didn't realise there where different types of 3.5 mm jack leads (other than stereo and mono)
is there a reason for this or anything I can do to get it working?
It doesnt seem to click in as if it's either too short or something is blocking it getting in (not a youthamism) the jack port is deffinatley clean of debris as brand new phone which is Xperia XA1 ultra by the way.
3.5 mm jacks do sometimes come in various lengths. I remember having a similar situation with these jacks some years ago and found a slight variation in the tip size (which activates the switch in the socket). Not saying this is your problem , just an observation from past experience.
