the sensor has been on since Monday and I put that in the options its still working on the official Dexcom app on my Iphone. I will ask on the face book page thanks again

@DunePlodder makes a good point about pairing a sensor with two phones.
I'm looking at this from a different libre/blucon context, and don't pretend to have any knowledge of dex, but what happened with my rig is that I started with blucon paired to it's own inhouse app, LinkBluCon, from the makers, Ambrosia Systems.
Then xDrip+ tuned up in September to allow input from blucon.
So I tried to get it paired with that instead. Couldn't get it working at all. It was a bit of a f**k it moment, but I eventually cottoned on to the fact that even though I'd closed LinkBlucon, it was still working away quietly in the background, demanding some bt input from the transmitter, and xdrip was asking it stuff as well, so the poor wee transmitter just got confused and stopped playing.
I sorted it by force closing LinkBluCon and deleting it from the phone. It worked ok with xdrip after that.
I suspect that if you're trying to run transmitter output to both the official app on iphone and xdrip on a separate android, the transmitter has basically said, ***, who am I meant to be talking to here?
You might have to make a judgment call at some point about unpairing the transmitter from the iphone app (turning the phone off won't sort it - it'll still be technically paired with that phone (I'm not 100% sure about that - just guessing)), deleting the official app, and then trying it through xdrip again.
My general take on it from my blucon experiences is that having a bluetooth transmitter running in the general vicinity of two programs running on two phones both demanding its attention is never going to work out well, so delete/erase one of them.
