This worked for me with my Mazda CX5 and Galaxy 10S+ This seems to have worked on my Jaguar XF 25t as well. 2 successful 10-minute trips with no disconnects. I've been through Samsung, Best Buy (Verizon referred us there), Verizon, UGiveWeBreak, Jaguar, and Verizon again. I spent hours with the folks who should be able to fix this yet no one had answers, and no one grasped the concept that audio connected and held, connecting to calls caused it to drop. Everyone, even Jaguar, said it was the car's fault. After Jaguar updated the vehicle, though, it was Samsung's fault and it was suggested I should have gotten an iPhone. Owning a hoity toity car does not shield one from sarcasm and useless feedback, fyi. Back to Verizon to get an iPhone (I've had it!) and they won't do the exchange, despite the product not working and none of them being able to remedy it. Along comes @userBy3teIqKlU with a quick post and life is already better. There were 3 phone apps for me to turn off so now I can play with which, if any, of those I can put back on to optimization.

That May have worked. I remained connected on two 10-minute trips today. One thing to note, once I switched Bluetooth to phone calls (after removing the phone apps from optimization) my phone disconnected from the car immediately. There was a confirmation for the phone accessing messages, to which I tapped, "ok." When I went in to the toggles in the Bluetooth on the phone Phone Calls and Contact Access were toggled on, Audio and Message access were toggled off. I toggled Audio and Message access back on, reconnected to the car, and remained connected. I should have thought of this solution to begin with! I didn't realize there were several apps related to the phone so it didn't even dawn on me, but still I feel like this is something I should have noticed. Thank you x 100! Here's to hoping it's not a fluke. :D

Jaguar update was a bust. I spent 3 hours in the dealership having them test and update. Works Fine with iPhones and S8s but as soon as an S10+ is hooked up for phone calls, boom, dropped. I connected phone calls and audio, dropped Immediately and went straight to FM radio. I turn off phone calls and I have Bluetooth audio the entire way home. I connect at home for phone calls, Bluetooth dropped instantly and went to FM radio. I looked in the Media menu and only had FM / AM / USB options, no Bluetooth. Turn off phone calls and Bluetooth Audio shows up in the menu. Unbelievable.
I have tried everyting within reason:
Samsung cusomer service couldn't solve it
WeBreakWhatUBring couldn't be bothered to try to solve it, though they lied about doing everything
Jaguar update didn't solve it
Verizon was of no help
Soft reset didn't resolve it
Factory reset didn't resolve it
It drops in a Toyota, Jaguar, and Volkswagen; though the connection in the Toyota is more stable than the Jaguar
It's not only my phone - the husband's S10+ also disconnects
My headphones, with the latest Bluetooth updates, drops when connected for phone calls, works fine when connected for only audio
Optimization doesn't matter for this issue because it's Only the phone call connection causing an issue
Media works fine
It's only the phone call connection that causes a problem
Yes, that's repeated - it's because people aren't grasping that it's Only the phone call connection that doesn't work
Media connection is stable
My next step is to go to Verizon and trade in for an iPhone. iPhone may be worthy of being made fun of for many reasons, but at least I'll have a working Bluetooth connection!

I'm going in Friday to see if Jaguar has an update. The service rep told me they did get a memo about Android and Jaguar having an issue. He said it wasn't going to be an update they're made aware of, it will be something that's done when we go in for service. Since mine had the nav card missing I'm getting that installed and will see if they have an update. I'll post an update either way so other Jag owners will know whether to go in or wait.
Bluetooth should be backwards compatible, especially with a car that's only 2 years old. I don't pretend to know Everything, but every article I've read backs me up on this theory - if Android made it truly backwards compatible there shouldn't be a need for an update. Maybe someone more knowledgable can explain it.

I have the same issue. We did some troubleshooting and discovered it's Only the phone bluetooth. Audio stays connected. Jaguar and Ford will allow you to connect only audio and when we did that we stayed connected. As soon as we connected the phone the connection dropped Every time. We went into the Verizon store yesterday and the girl went through all the steps listed on this forum and nothing resolved our issue. As the previous poster mentioned, Android Auto does not support Jaguar so there's no reason for us to use that. My husband's 2017 Toyota Tundra also drops the connection and he also does not use Android Auto. The Verizon girl tried to give us that solution and I went ahead and did it, just to satisfy all the troubleshooting attempts, but nothing was resolved.
The full model number of the phone: SM-G975U
Baseband version of the phone: G975USQS1ASD9
Year, make and model of the vehicle: 2018 Jaguar XF 25t and 2017 Toyota Tundra
Service Provider: Verizon Business
It's a Major issue for us as we use our phones for business and it's beyond unprofessional to have calls dropping when speaking with investors who invest hundreds of thousands of dollars into each project. My husband operates in a mobile office (his truck) so he experiences this far more than I do. He's also the one who speaks to more people, or rather, hangs up on more people these days. Our S8+ phones never dropped connection so this is something new with the S10 Plus.
The girl at Verizon told us there was a bluetooth stabilization update pending and Samsung was waiting for all the service providers to accept it; however, my husband noticed that update was pushed out May 20, 2019, which would be the baseband version we have currently. We both concur that update did Not stabilize the phone connection for bluetooth. Yesterday in the first 10 minutes of our drive my phone disconnected 7 times. We tried his phone to rule out the potential of mine being the culprit and his also dropped connection numerous times.
One suggestion was to turn off battery optimization for bluetooth (Horrible solution, with BT being a battery hog, but we're desperate and have car chargers), but that did not resolve the issue.
