Pretty much all phones have the needed "hardware" in the FM/BT/WiFi combo chip. But hardware disabled phones have the FM antenna pin grounded and thus useless.

Only exception I've ever seen to this is on the G2, which had a very unusual FM/BT switch chip for audio. G3 might possibly have the same, but my primary thoughts about G2 was that the chip was a strange hack they might not repeat for the G3.

G2 service manuals had schematics that better verified. Perhaps the G3 will have service manuals eventually released/leaked to confirm.

I came across the service manual. I'm really not sure how to understand all that into but if it helps someone figure this out if FM can work I'll send it to you. Just PM me with into its like 69mb large over 350 pages.

Just send me a link via email: mikereidis@gmail.com .

In most cases like this, if the schematic has the details, it shows that FM antenna connection is optional, without any indication of which variants are connected or not.

I am pretty sure it's a lost cause.

It's rare these days for a phone with no stock FM app to be able to work. Only examples I can think of are the 2 year old HTC One M7 GPE Google Play Edition, 1 year old-ish Verizon HTC One M8 and Verizon Xperia Z3v I think.

FM on Android flagships is dying; my terminallty decling Spirit income shows that, and I am now looking to move into the Android Auto world.

return email from the fcc
"Thank you for your letter supporting the inclusion and activation of FM chip sets in mobile wireless handsets. Your views on this issue are very important.
As the Chairman recently indicated in a letter in response to a Congressional inquiry, he agrees with you that FM chip sets are a good idea, and understands that there are an increasing number of phones that include them.
Please be assured, one of the Commission's highest priorities is to ensure that all Americans have the capability to receive timely and accurate alerts, warnings and critical information regarding disasters and other emergencies irrespective of what communications technologies they use. As we have learned from previous disasters, such a capability is essential to enable Americans to take appropriate action to protect their families and themselves from loss of life or serious injury.
The Commission has a well-established policy of technologically-neutral regulation of the wireless telecommunications industry, which allows mobile wireless providers and equipment manufacturers to select and incorporate the technologies that will enable them to most effectively and efficiently deliver mobile alerts. Commission regulations do not prohibit activated FM chips in wireless handsets, and at least one major carrier has embraced the technology by providing FM radio access to their mobile customers."

email fcc and demand cell carriers to no longer disable fm chips. it a matter fo public safety.
