I am very sorry hear of your troubles, but I imagine you are not alone, despite the lack of posts to your thread.
CoDi is junk, it always has been. It won't list all your contacts, it's a battery drain, it will inadvertently mute you with the wrong press of your cheek, I could go on and on, and when you look through the other threads of complaints, you'll see a plethora of weirdness that CoDi visits on its users, and everybody seems to have a different problem.
It's not a coincidence that Planet moved far away from CoDi wiith the upcoming Astro.
I now use my Cosmo as a Linux-only laptop and the first thing I did was disable CoDi.
Planet has made interesting devices, but like other niche companies, they have to sort out the issues afterward not before, which is a drag for users, and they never truly sorted out CoDi.
I hope you can find pleasure in the Cosmo despite CoDi's failures, since the phone does have unique qualities.
