Galaxy S8 calls keeps dropping after installing Android Oreo, earpiece making metallic sound during calls

One of the most annoying issues that anyone can experience is when having difficulties during calls. Calls issues are usually difficult to pin down because there’s a number of variables to consider. In many cases, issues regarding calls are fixed by doing the usual software solutions or asking an operator for help. In this troubleshooting post, we give you the possible solutions that a user can do when faced with situations mentioned below on their #GalaxyS8.

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: Galaxy S8 calls keeps dropping after installing Android Oreo

I am having problems with call dropout on my Galaxy S8, I have contacted Samsung support and they told me to Reset my phone. I did this but the problem is still there. I contacted my service provider and they had no solution, I have tried replacing my SIM but it’s still happening. Do you have any suggestions? Also, this problem only started after I upgraded to Oreo. Thanks. — Michaela 

Solution: Hi Michaela. Some Galaxy S8 and S9 users have reported call drop cases after installing Android Oreo so we the problem may be likely caused by a network bug or a software glitch on the device. While this problem is not universal, there seems to be an increasing number of S8 and S9 devices that were affected. At this time, we’re still gathering data about the situation and we can’t confirm if there’s an effective solution about it at this time.

When it comes to post-update issues, there’s usually a set of possible solutions that can be tried. At most, what you can do is a factory reset. But even this solution is limited as it can’t fix issues caused by poor or inefficient, which we think is the main cause of your problem. When we say coding issue, we’re referring to bugs that develop because Google, Samsung, or any publisher of the firmware running on your device has screwed up. Android operating system is made up of software codes and just like any piece of code, it can be imperfect.

Knowing whether or not you have a coding issue is not straightforward and technically, only a developer, which can access your device’s software logs may be able to identify it. Samsung, Google, or any other company does not offer services to look into a devices software logs though (it’s not economically practical for them) so they rely on reports or ticket bugs provided by users. So, the more tickets or reports about a particular bug comes in, the more likely a concerned party will act on it. At this time, we have no idea how many S8 and S9 users are having the issue you’re experiencing but a quick search on the web gives the impression that it’s not isolated to any particular carrier or region.

The best thing that you can do right now, given the fact that the usual suggestions for fixing post-update issues are not effective, is to wait and see. Samsung or Google may already be working on a fix for this issue so hopefully, the next update will include the patch. Make sure that your device is set to automatically download and install any available Android update in order not to miss it.

Problem #2: Galaxy S8 earpiece making metallic sound during calls

Hello. I just received a refurbished Galaxy S8 from Gazelle.  I noticed there’s a tinny sound or metallic reverberation when I’m holding the phone up to my ear on calls. I’ve been trying to research this and saw a lot of people commenting about speaker issues, but I don’t think this is the same as it’s the earpiece, not the speaker or headphones.  I only saw one other person complain about this, but it is very annoying. Is this something that could possibly be “fixed”? Or should I look into returning the phone? Thank you! — Jackie Jackie

Solution: Hi Jackie. We don’t think we get the exact picture of the issue you’re trying to describe here but generally, there are only two possible reasons for that. One is a possible app or software bug causing the unnatural sound, and the other is hardware-related. The latter can only be fixed by repair or replacement so if you’ve already tried to factory reset your device before contacting us, all you need to do is to let Samsung decide whether or not they can do something about it.

For reference, here’s how to factory reset your S8:

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  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 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: Galaxy S8 unable to make calls or send texts as cellular signal keeps disappearing

Hello. So this just happened out of the blue a few days ago. My phone had no issues outside of storage issues every once in a while (some apps couldn’t run because I had no room on my phone), but otherwise no problems. Now however, my phone will not send texts or make phone calls. Half the time it says emergency calls only (and this is in places I had service before), the other half of the time it looks fine but won’t send texts and will drop the call before it even rings (it won’t even tell me I don’t have service, it just never connects the call). Half the time, the call/text will drop but I’ll still be able to browse the internet, the other half of the time everything shuts down (no internet, no calling, wifi works but nothing relating to my service does).  A restart fixes everything. Emergency calls only goes away, phone will send texts and calls, data comes back and I can browse back to full speed. While I am using my phone this is not an problem. Calls won’t drop, and if I’m actively texting, messages will go through. This usually happens when I’m not using my phone for say like an hour or so. If I only browse without text/call, I lose that. If I text/call but don’t browse, I lose my browsing. Restarting is the only way to fix this. It’s very annoying, and I don’t understand why I have this issue. It doesn’t appear to be a service issue since everything works while I am using it, and I don’t know if it’s a phone issue, since restarting my phone fixes everything. Any ideas? Anyone else have this issue? Also, I have Walmart Family plan with T-mobile. — Sam

Solution: Hi Sam. Try to wipe your phone’s cache partition first and see what happens. Sometimes, Android may encounter errors or bugs if its systemc cache, stored in the cache partition, is corrupted. To ensure that the system cache is in good shape, you want to clear the cache partition. Here’s how:

  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 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 to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Should cache partition won’t fix your issue at all, try to clear the network settings with these steps:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset network settings.
  5. Tap RESET SETTINGS button.
  6. Restart your S8 and check for the problem.

Finally, if both suggestions won’t help at all, make sure not to forget to do a factory reset. There may be an issue with the software so you want to make sure that you check if that’s the case. Refer to the steps above on how to factory reset your S8.

Should that won’t resolve the issue either, talk to your operator for what to do next.
