The issues you're experiencing with your Galaxy S23 after the One UI 6.1 update seem quite severe, affecting multiple functionalities like speakers, calls, and external audio connections. This isn't a common problem, but it does happen occasionally with software updates. Here are several steps you can take to address these issues:
### Common Solutions
1. **Restart the Phone**:
- You've mentioned restarting, but try a force restart by holding the power and volume down buttons simultaneously for about 10-15 seconds until the phone restarts.
2. **Check for Updates**:
- Sometimes, follow-up patches are released to address issues caused by new updates. Go to **Settings > Software update** and check if there's a newer update available.
3. **Clear Cache Partition**:
- Boot your phone into Recovery Mode and clear the cache partition. This won't delete your data, but it can help resolve issues caused by corrupted cache files.
1. Power off the phone.
2. Press and hold the **Volume Up** and **Power** buttons until the Samsung logo appears.
3. Use the volume buttons to navigate to **Wipe cache partition** and select it using the power button.
4. Confirm and reboot.
4. **Safe Mode**:
- Boot into Safe Mode to check if a third-party app is causing the issue.
1. Press and hold the power button.
2. Long press **Power off** until **Safe Mode** appears, then tap it.
3. Check if the speakers and external devices work. If they do, the issue might be with a third-party app.
5. **Reset App Preferences**:
- Sometimes, resetting app preferences can resolve issues.
1. Go to **Settings > Apps**.
2. Tap the three-dot menu and select **Reset app preferences**.
6. **Check Sound Settings**:
- Verify that your sound settings aren't misconfigured.
1. Go to **Settings > Sounds and vibration**.
2. Ensure that **Sound mode** is set to **Sound** and not **Mute**.
3. Adjust the volume settings for different sound categories.
### Advanced Solutions
1. **Factory Reset**:
- As a last resort, perform a factory reset. This will erase all data on your phone, so make sure to back up important information first.
1. Go to **Settings > General management > Reset > Factory data reset**.
2. **Re-flash Firmware**:
- If none of the above works, you might need to re-flash the firmware using Samsung Smart Switch or Odin. This is more technical and typically best done with professional help or support from Samsung.
