Calls cut out on S21 Ultra after June 2022 Update

I've been having issues with my phone calls ever since I updated to the latest S21 Ultra security patch on Verizon a few days ago.

The update was SP1A.210812.016.G998USQU5CVF1

The person on the other end of the call ends up cutting out for a good 5 seconds and I can't hear them. Then they come back, and they cut out again, so it repeats. My service has not changed and I have 5G coverage in my house.

I tried most troubleshooting steps with no luck (restarted phone, reseated SIM card, safe mode, cleared caches)

Not sure if others on here have had this issue, but I've seen a few forum posts on Samsung's website about the problem and it doesn't seem to be just me.

I read in a different forum that an update was available, G991USQU5CVG9. I didn't get a notification so I checked my settings...and voila, there was an update! I downloaded it and tested it by calling Verizon Support since I know it would take time before a person answered. After a couple minutes, there was no cutting out! Crossing my fingers! Since this was such an important update to fix a huge problem, I'm surprised I didn't receive an 'update available' notification like I usually do. So check for Software Updates in your Settings! Good luck!

I'm also having this same issue after the recent software update. My phone shows 5G signal, but still have "network connection " issues. The issues seem to be sporadic. My spouse called me yesterday, but on my end I had no missed call or notification. Hopefully Verizon does something soon to correct this issues. Since obviously it is a known issue amongst many of their customers.

Experiencing same issue with calls cutting out since latest S21 Ultra security patch from June 29th.

Experiencing the same issues here as well. Unfortunately these are business lines and my field guys can't complete a conversation to get their jobs done. How is this issue not fixed yet??? Verizon S21 Ultra here.

There are a bunch of reports on the Samsung forums of the latest update causing these issues. The only solution I've seen is to turn off 5G and 4G go back to the early 2000's and enable 3G as your network. This obviously impacts your data side of things!

Thanks all for the replies. It legitimately sounds like a software bug and I'm hoping either Samsung or Verizon would acknowledge the problem. It's troubling that a $1200 phone is having this issue.

Here is what I got from the same issue discussing this with a Samsung agent online. It still does not fix the issue they are having. I just thought I would share this with you. Have a great day!!!

Kindly follow these steps.:
1. Do a quick restart
To fix the microphone problem in your Android, try this simple trick first up! If you haven’t restarted
your phone in a long time, now is as good a time as any. Restarting your smartphone clears any
open apps, and can possibly be a quick fix to your problem.
Turn off your phone and wait for about 10-30 seconds before turning it on again. The process will
refresh your system. Check to see if the problem is solved.

2. Clean your microphone with a pin
This mic fix on your Android phone is simple, yet it’s super helpful. Your phone accumulates dirt from
using it for extended periods of time.
Mobile phones are vulnerable to dust or small debris, and can get into the small openings of your
phone. You might not know it, but tiny fabric pieces can get stuck, especially if you’re always carrying
it in your pocket.

Gently poking and cleaning the mic on your Android phone might fix the problem
Your mic is a small hole beside the USB connector. You can either blow at it directly or get a small
pin or a thin needle and carefully poke the hole to remove any dirt inside.
3. Disable the noise suppression
Some Android phone releases come with a cool feature called noise suppression/noise reduction. It
reduces the background noise when you are on a call or recording a video.
However, this can be a cause of why your microphone is acting up.
Go to Settings.
Select Call Settings.
Look for the Noise Reduction option and disable it.
Restart your phone and check if the problem is solved.

4. Remove third-party apps
Some applications can cause your phone to malfunction. They can sometimes interfere with your
phone and users might experience minor anomalies. and this might be the root cause of the
microphone problem in your Android.
Run your phone in safe mode to disable all third-party apps temporarily. Try a test call or use the
recorder to check the microphone.
If it is working fine, then the culprit is within your apps. You can check the apps that are using the
microphone by going to Settings -> Apps -> App permissions -> Microphone permissions.

You can try checking each app one by one, but that can take time. If you want a quick fix, you can
back-up your phone to retain all vital information and do a factory reset.

You might not notice it, but you might have connected your phone to a Bluetooth device that has its
own mic. Be sure to disconnect your phone from other devices and do a quick restart.

6. Force stop Bixby Voice
Are you a Samsung Galaxy S9 user who is experiencing the same problem? It could be because of
the Bixby Voice.
Open your phone’s settings and tap Apps. From there, select Bixby Voice, choose Force Stop and
check if the problem is solved.

Get it fixed, which is one of the last options for fixing the microphone problem on Android. If your
microphone is broken or malfunctioning, you should have it serviced at a service center.
You can call the customer service hotline to get additional information about the phone. If your phone
is still under warranty, you won’t have to pay anything.
If your phone has passed its warranty time, you will be responsible for the repair costs or the
microphone.
