How to fix Galaxy S9 Bluetooth issue: won’t stream audio to car Bluetooth system

Today’s troubleshooting article will provide solutions for more #GalaxyS9 problems. We bring you four more S9 cases in this post so we hope that you’ll find this helpful.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem #1: How to fix a Galaxy S9 that keeps saying storage space is low

My new Galaxy S9 says I’ve used close up to 62gb out of 64 gb. When it lists what I’ve stored on my phone, I’ve got : Documents 9.99mb, Images 178mb, Audio 5.98 mb, videos 210 mb, Apps 6.3 GB. There is NO way that adds up to 62gb. It is extremely frustrating to have a notification pop up reminding you that you’re low on space when you’ve barely used any.

Solution: In most instances, the numbers displayed under Settings > Device maintenance > Storage don’t usually add up. That’s because the actual storage space used by apps are not taken into consideration at all. For instance, if you download a show in your Netflix app and save it locally, the Settings app won’t show that the app has saved something. Instead, it will continue to show the default, initially detected size of the Netflix app.

Some apps like games may install large updates and they too will not be displayed by Settings app under its Storage section so you’ll probably end up getting inaccurate reading. There’s no official explanation from Samsung or Google (the Android developer) why this is so and defeats the purpose of this feature really. Hopefully, this will get addressed in the next iteration of Android or in upcoming Samsung devices.

The best thing that you can do is to assume that your device is indeed getting low on storage space. To avoid getting the pesky warning about low storage space, try deleting apps that may be keeping huge data. Alternatively, you can try to move them or some stuff to an SD card.

Problem #2: Galaxy S9 keeps crashing back to Home screen

Hey guys. For some odd reason when I open my apps, a few seconds later it takes me back to the homescreen. I can open it again but most of the times it had taken me back to the home screen. I can usually by pass this just by opening it around 4-5 times and the app will behave normally but it gets really annoying when I open the app and a few seconds later it automatically takes me back to the home screen. Is there anyway to fix this problem?

Solution: The apps you’re talking about may be crashing. If this only occurs to a few select ones, the first thing that you want to do is to clear their data. Here’s how:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Show system apps.
  5. Find and tap your app.
  6. Tap Storage.
  7. Tap Clear Data button.
  8. Restart your S9 and check for the problem.

You can also try to reinstall them if nothing happens after clearing their respective data.

If the problem occurs to a lot or all apps, there may be a bug causing the system to close them. The first thing that you want to do is to wipe the cache partition with these steps:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Some apps may crash if there’s slow or intermittent internet connection. If the apps you’re having trouble with are the ones needing internet only, there may be an internet or network bug behind it. Try clearing your device’s network settings to see what happens.

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset settings.
  3. Tap Reset Network settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

Should nothing work at this point, consider wiping the phone thru factory reset. This will return all software information back to their defaults. This is often an effective method to fix unknown system bug. Be sure to back your data up before doing it.

  1. Create a backup of your data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Problem #3: How to fix Galaxy S9 Bluetooth issue: won’t stream audio to car Bluetooth system

Country: Belgium

Carrier: Proximus

Hello. I’m contacting you in regards to the Bluetooth issues article. Since i have returned from a US trip, my phone is unable to stream audio to my BT car stereo. (Pioneer DEH4800BT). It connects perfectly fine and I can even read the track ID or skip the song on the stereo itself. My phone can still stream audio to any other device,(Headphones, soundbar,..) I’ve also tried numerous steps to fix this (software updates, re-pairing,hard reset) but nothing seems to work. When i was in the US i paired my phone to a similar car stereo, a older one actually, and that worked fine. I hope you guys know any kind of solution for this. Thanks in advance.

Solution: There may be a bug in the phone or in your car’s system so the first troubleshooting step that you want to do is to refresh the connection between them. You can do that deleting all Bluetooth pairings in both devices, then pairing them again afterwards.

If you’ve already tried to delete pairings in both systems before contacting us, or if nothing happened after doing it now, you can also try see what happens if you clear your S9’s network settings. Doing so will delete wifi names and passwords, cellular configurations, VPN settings, and all Bluetooth-related setups in your phone. With all custom network settings erased, your phone will be forced to acquire new settings for all network functions again, thereby refreshing them. This is often an effective way to solve network bugs. Here’s how to do it:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset settings.
  3. Tap Reset Network settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

Problem #4: Galaxy S9 microphone won’t work with car Bluetooth system during calls

Galaxy S9. Worked great the first couple weeks, and now that I cant return it, its doing what my S7 did. The problem I’m having is with bluetooth in the car. It allows me to make call, and I CAN hear the person who I called saying “hello? hello?” but they cannot hear me. All they hear is what’s been described as a buzzing sound, like an electronic laser buzz of sorts.

I’ve cleared my car system, I’ve reset and even erased my cellphone back to factory settings. After all that, it worked for a day, but now it’s back to buzzing. If I switch to speakerphone or use the regular method of placing calls, it works fine.

Also, music plays fine through the bluetooth and car speakers. It’s weird and annoying. The phone is 1 month old and has updated software from a wi-fi download. It honestly worked great until the software update. I cant blame that…or can I. Still, it reverted back to buzzing even after I deleted the entire phone. Good luck with fixing this issue. I haven’t been able to figure it out. I’ve even taken the car into the dealership to test the bluetooth and they said it was working properly. The vehicle is a 2012 Honda Civic Si, if that helps to know. Thanks!

Solution: In order for two Bluetooth devices to work, both of them must be capable of supporting the same set of rules or profiles. Bluetooth profiles make it possible for your Galaxy S9 to communicate with your car’s Bluetooth and transmit audio to it. Below each major Bluetooth profiles are subgroups that may become the source of incompatibility issues. After a software update, your phone may have added (or removed) more specific rules that now leads to both systems being unable to work together. Because phones usually sport more advanced Bluetooth systems than in-vehicle Bluetooth systems do, incompatibility problems can happen even if the two were previously working fine before the update.

If doing the basics like deleting old pairings, resetting network settings on the phone, or restarts won’t help, there’s probably nothing much that you can do. As an end-user, you can only use whatever Bluetooth capabilty is provided in your gadgets. There’s no way for you to add or remove profiles or define what functions they support.

Naturally, your car dealership will say the Bluetooth system is fine (it does not have any issue connecting to the phone after all). The real problem lies in the fact that your car Bluetooth, while still functional in some respect, has become obsolete relative to your phone’s Bluetooth capabilities. Remember, Bluetooth systems are constantly evolving and just like any other electronic gadgets today, they may also be left out as newer systems come along. If you can’t secure a more advanced Bluetooth system for your car, then you’ll just have to face the reality that it will never work properly again with more advanced phones.
