Hi there! I understand you're facing issues with the PreSonus QMix app on your Samsung Android phone—specifically, it connects but malfunctions, levels jump around, and you don't see the mixer controls. Let's work through it together.

To start, could you tell me which model of Samsung phone you have and if your mixer is a StudioLive Series III or an earlier model? Also, have you updated the mixer’s firmware recently? Sometimes outdated firmware can cause connection glitches or missing fader controls in QMix.

In the meantime, here’s a step-by-step checklist that often helps with such problems on Android:

1. Update Firmware and App
- Make sure your StudioLive mixer’s firmware is updated to the latest version (version 2.0 or higher is required for full QMix v3 compatibility).
- Update the QMix app from Google Play to the latest version.

2. Network Setup
- Confirm your phone and mixer are on the exact same Wi-Fi network.
- Disable multiple network connections (like cellular data along with Wi-Fi) to avoid conflicts.

3. App Permissions
- On your Samsung Android (version 10), go to Settings > Apps > QMix and ensure all necessary permissions, especially for local network and microphone, are enabled.
- Sometimes Android can revoke these permissions if the app is closed or after updates, which causes malfunctions.

4. Reset Network Settings
- On your phone, try resetting network settings (Settings > General Management > Reset > Reset network settings). This clears any Wi-Fi or connection issues.

5. Disable Wireless Security Temporarily
- Sometimes router firewall/security can block communication; briefly disable wireless security to test if that resolves the issue.

6. Close Other Apps
- Android’s memory management can interfere if many apps are running. Close other apps to free resources for QMix.

If after this the levels still jump erratically or the mixer controls don’t appear, it’s often related to a mismatch between app version and mixer firmware or permission revocation on Android 10.

Please let me know the answers to my questions and if any of these steps help. We can then try further advanced troubleshooting if needed.

Are you satisfied with this approach so far?

My phone is a Galaxy A12. The mixer is a StudioLive 32R.

Thanks for the details! You have a Samsung Galaxy A12 and a StudioLive 32R mixer—very helpful info.

From what I gather, the PreSonus QMix-UC app is designed specifically for StudioLive Series III mixers, and the StudioLive 32R is a third-generation model, so it should be compatible with QMix-UC in principle. However, a key point here is that many users report limited or no support for certain Android devices, including the Galaxy A12, especially with earlier versions of the app and mixer firmware. This could explain why your QMix app connects but then malfunctions, with jumping levels and no visible mixer controls.

To make sure, here’s what I suggest:

1. Confirm Firmware Version on StudioLive 32R
- Use the PreSonus Universal Control software on a PC or Mac to check and update your StudioLive 32R firmware to the latest available version. Firmware 2.0 or higher is essential for reliable working with QMix-UC.

2. Verify QMix-UC Version
- Ensure your QMix-UC app from the Google Play Store is fully updated to the latest release.

3. Compatibility Limitation
- Unfortunately, the Galaxy A12 is an entry-level phone with limited hardware and network capabilities that sometimes cause issues with apps requiring stable, low-latency Wi-Fi connections like QMix-UC. At present, there is no official statement supporting full compatibility of Galaxy A12 with QMix-UC. This is a known limitation and might be why you're experiencing these issues.

4. Alternative Devices/Test
- If possible, try connecting another Android device or an iOS device with QMix-UC to your StudioLive 32R on the same network. If it works well on another device, then the issue is very likely the Galaxy A12’s limited support.

5. Network and Settings
- As before, verify your phone and mixer are on the same Wi-Fi network and that app permissions are fully enabled. Closing other apps, restarting the phone, and resetting network settings can help but may not fully fix hardware compatibility gaps.

In summary, while the 32R should work with QMix-UC, the Galaxy A12 phone isn’t officially supported or tested for full compatibility, which explains the connection but malfunction symptoms.

If testing with another device confirms this, the best options are either using a supported device or potentially looking into compatibility layers or third-party apps, though these carry limitations.

Would you like me to guide you on checking and updating your mixer firmware? Or would you like help with testing on another device? Let me know how you’d like to proceed!

StudioLive 32R firmware is up-to-date. Probably need a different phone. What phones are supported?

Thanks for letting me know your firmware is up to date—that’s great! Regarding supported phones for using the PreSonus QMix app with your StudioLive 32R, here’s what I found to guide you:

- The official QMix-UC app supports Android devices running version 6.0 (Marshmallow) or higher. Your Galaxy A12 is Android 10, so it meets this baseline OS requirement.
- However, PreSonus does not provide an official, published list of specific supported phone models for QMix-UC, especially with the 32R mixer, probably due to the wide variety of Android hardware and network configurations out there.
- Most compatibility is based on the device having a stable Wi-Fi connection and the capability to handle low-latency audio control. More powerful or mid-to-high tier phones from the Samsung Galaxy S series (like S9, S10, S20 and newer) or Google Pixel phones tend to perform better with QMix-UC.
- Many users report that entry-level or budget phones like the Galaxy A12 can face issues because of their hardware or network limitations, which might cause level jumping or missing mixer controls like you described.
- For best results, using an iOS device (iPhone or iPad) tends to offer the most reliable experience with QMix-UC, especially because iOS devices have more consistent Wi-Fi networking and audio handling.
- Some users have success with mid-range and flagship Android phones by ensuring: the app is up to date, mixer firmware is current, and that phone permissions and network settings are fully optimized (as mentioned before).

In summary, if you want a new phone to use with StudioLive 32R and QMix-UC, consider a model with:
- Android version 6.0 or higher (your current system is fine)
- Good Wi-Fi capability (preferably 5 GHz dual-band support)
- More powerful CPU and RAM to handle app processing smoothly; Samsung Galaxy S series (from S9 up), Google Pixel devices, or higher-end OnePlus and similar flagship phones usually work well.
- Alternatively, an iOS device like an iPhone or iPad will likely give you the smoothest, most consistent QMix-UC experience.

That will be all for now. Thank you.

Hi! You’re curious about the PreSonus QMix app and its features—happy to give you an overview.

QMix-UC is a free app designed to let musicians control their own monitor (aux) mixes wirelessly from their mobile devices while on stage. Up to 14 musicians can independently adjust their personal monitor levels using the app, which communicates directly with compatible PreSonus mixers like the StudioLive Series III and StudioLive 32R (with firmware 2.0+). This means each musician gets full control over what they hear without having to ask a sound engineer to make adjustments.

Here are some key features of the QMix-UC app:
- Personalized Mix Control: Each user can change the volume levels of different channels in their monitor mix, adjusting vocals, instruments, and other inputs to their preference.
- Robust Permissions: The app allows restriction of access so each user can only control their specific mix, keeping mix control secure and organized.
- Wireless Connectivity: It works over Wi-Fi, connecting your phone or tablet directly to the mixer’s network for low-latency control on stage.
- Cross-Platform Support: Available for both Android and iOS devices.
- Easy-to-Use Interface: Simple sliders and controls make mixing intuitive even for users who aren’t audio tech experts.

It’s designed to empower musicians during live performances or rehearsals, providing quick and hands-on mixing from wherever they stand on stage1 2 9.

If you're interested, I can guide you on getting it set up or using specific features on your device. Does that help explain the app’s capabilities?

Does PreSonus QMix app support iOS and Android?

Hi! Yes, the PreSonus QMix-UC app supports both iOS and Android devices. You just need to connect your iPhone, iPad, or Android phone/tablet to the same Wi-Fi network as your compatible StudioLive mixer, and the app lets you control your personal monitor mix wirelessly.

While it was initially developed for iOS, official Android support has been added and improved over time, though some Android devices vary in compatibility due to differences in hardware and OS versions. Overall, QMix-UC works on both platforms to give musicians control over their mixes from their mobile devices4 5 7.
