Bluetooth not working on IPhone XS

Make an appointment with the Genius Bar at your local Apple Store.

They have Bluetooth devices there, so if you can’t connect there it’s your phone, if you can it’s your Bluetooth device.

I had to have the Bluetooth on my old device forget my Fitbit and then I set it up on my new phone and it worked fine

Apple will never fix it globally, because it is a problem with your phone. If you have failed to solve it with all of the standard troubleshooting steps make a genius bar appointment to have an Apple tech look into it.

You need to put a Bluetooth device into Pairing mode, then go to Settings/Bluetooth and tap its name to connect. Even if the device connected to a previous phone. Depending on the device, you may need to reset it to it's factory settings first, as some devices have a limited number of devices they can pair with at the same time.

I love the canned responses to issues with bluetooth. Let me tell you I had an iPhone 6s without any bluetooth issues, then got the Xs and nothing but headaches ; at least with my Bose Soundlink Mini . It connects I hear the music, then it randomly disconnects in which I can't get it to work again. The iPhone even says it's connected to the Bose but no sound comes out. I then have to go through the whole 'forget device' and repair it - rigamaroar. Now, I challenge any Apple engineer to repair every time you want to use your device and let me know how long it takes for you to want to throw your iPhone out the window ?

I'd be contacting the manufacturer of the other device to find out why it apparently isn't following standards.

Why? Because there are few issues connecting with the vast majority of Bluetooth devices extant, and though new Bluetooth standards are backwards-compatible, that doesn't work if the original device didn't properly implement the spec to begin with.

What does Bose have to say? Have you contacted them to ask?

Have you paired the Bluetooth device to your phone? No BT device can connect until after it is paired. See this Apple support link-->Pair a third-party Bluetooth accessory with your iPhone, iPad, or iPod touch - Apple Support

I had the exact same problem.. with my XS iPhone. I got the run around from Optus in store they didn’t have a clue and told me Hyundai needed to upgrade my Bluetooth which was absolute crap..

I went outside the store and rang them again one more time and they told me to go to:

settings

general

reset

reset network settings.. it worked..

then turn your phone off and on.. it should work.. good luck. I researched and researched to find this out and managed to get someone that new how to fix the issue.

I hope this helps..

You fix this by removing pairing anything else they might have been connected too... Like my headphones was giving me a hard time until I noticed I moved away from my macbook. Then again when approaching my nexus 5 that has a older les sophisticated bluetooth still took it. from my XS.. So turn of any devices that might use Bluetooth and Wifi routers have something called a dual mode, if yours has one I recommend turning it on. It will give abit slower connections but nothing you’d notice unless it's over ten years old. If you do this the wifi in your apartment or house will stop interffering with your bluetooth devices. Fair reminder, remember that the older gadgets you use that’s bluetooth enabled the more trouble they will have working in unison. Try to keep a standard of Bluetooth 4.2 wireless technology attest and all your devices should workouts fine all att once. Good luck but you shouldn't need it!

I don't see hundreds. That's the number that were interested in the subject, not necessarily the number with the problem. But even assuming hundreds (500?), that's a drop in the bucket of the 100 million sold. And most likely they don't even all have the same problem.

No matter what problem you have, with over 2.2 billion iPhones sold it is just about guaranteed that someone else has the same problem. Knowing that is useless information. And when there is a real problem people do post about it (not just click "I have the same question") as illustrated in this old thread from 7 years ago:

That's almost 13 thousand posts at a time when there were only 100 million phones in use. And that problem affected about 5 million of them. So the very small number of users showing an interest in this current subject demonstrates how rare it is. To get Apple's attention you need to either contact Apple Support using the link at the top of this page or by making a genius bar reservation and demonstrating it to an Apple tech. Those are the sources that Apple uses to identify repeatable problems.

I am having the same problems with my Series 4 Apple Watch, they should be really near to each other to have a constant connection. I think there is a problematic situation going on with 2.4 ghz Band wi-fi and Bluetooth. Most of the time I am not able to watch as there is no available known wi-fi networks outside. I don't know how to solve it as I try everything that I can do from resetting watch to setting up everything new. Even whenever I open my airpods' lid, it never show up an animation and also if you hold apple watch waiting for a setup near to phone, it never promotes that there is a new apple watch waiting for a setup.

BTW, Genius Bar couldn't fix it. They tested the phone with Apple airpods and it worked fine and they concluded it had to be my BT devices. The issue can be replicated in the car and two different Bluetooth headsets. The issue has to be with the phone.

Follow the tips here:

If you can't connect a Bluetooth accessory to your iPhone, iPad, or iPod touch - Apple Support

I believe both iOS 11 and iOS 12 supported Bluetooth 5.0, but that doesn't mean there isn't a new incompatibility.

It never hurts to take it in; your store has a lot of Bluetooth devices so if it's your unit it will be instantly obvious.

new IPhone X max can’t connect with any Bluetooth had a IPhone 6 no problem

iPhone XS | 512 | Gold arrived on the 21st as promised. Embattling the same issue, immensely frustrating oversight! There’s gotta be a fix soon, several job related apps will not work without Bluetooth additional to being safe/hands free.

Make sure you delete any pairings involving your Xs from the Hyundai and the Hyundai from the Xs. This should work, in theory, as my XS Max has worked in every Hyundai rental car I've had, but I don't know the age of yours.

You may also want to check with your Hyundai dealer to see if there is a firmware update available for your head end, as all of my rental vehicles were 2017 or newer.
