License FAQ and troubleshooting

Most Google Play licensing problems fall into one of two groups: a payment did not complete, or a completed purchase is not being recognized.

Ko-fi license requests are handled separately. Start with the section that matches your situation.

Google Play and Ko-fi are separate license systems

Google Play licenses are managed by Google and tied to the Google account that owns them. Ko-fi licenses are managed manually. A license cannot be converted or transferred between these systems.

Start with your situation

• If Google Play does not complete the payment or no completed order exists, follow A Google Play purchase cannot be completed.
• If the order completed but Symfonium is still locked, follow A completed Google Play purchase is not recognized.
• If you need an initial Ko-fi activation, or a device or ROM change produced a new trial/device ID, follow Ko-fi licenses and device changes.

License basics

Where can I find my Google Play order number?

A completed Google Play purchase normally uses the GPA. prefix for its order number. You can find it in your Google Play order history or Google Payments. Make sure you are signed in with the account used for the purchase.

Will my Google Play license work on another device?

Yes, on a compatible Android device with Google Play, as long as it uses the same Google account that purchased the unlocker. Install Symfonium through that account, then use Restore license on the purchase page if the app remains locked.

Can I transfer a Google Play license to another Google account?

No. Google Play does not allow purchases to be transferred between accounts. If several Google accounts are present on the device, Symfonium must be installed through the account that purchased the unlocker.

Can I share the license through Google Play Family Library?

No. The Symfonium unlocker is an in-app purchase, and Google Play does not allow in-app purchases to be shared through Family Library. The license can be restored on compatible devices using the purchasing account, but it cannot be shared with another account.

Will a Google Play license work without Google Play?

No. Google Play must be available and able to validate the purchasing account.

Can I move a license between Google Play and Ko-fi?

No. They are separate license systems. Moving an existing Ko-fi license to a new device ID is a different, manual process described below.

How do I request a Google Play refund?

Start by requesting the refund from Google Play. If Google Play does not handle the request, contact Symfonium support with the Google Play order number, purchase date, amount paid, and reason for the request. See Get help and share feedback for more details.

A Google Play purchase cannot be completed

Google Play processes the payment. Symfonium does not receive your card details and cannot resolve a declined or pending transaction. Work through these checks in order:

1. Confirm that the Play Store is using the Google account and Play country you intend to use for the purchase.
2. If your Android version provides App data sync under Android Settings > Accounts > Google, ensure it is enabled for the purchasing account.
3. Check whether an order was created in your Google Play order history. A pending or cancelled transaction does not provide a license that Symfonium can restore.
4. Follow Google’s payment troubleshooting. Complete any confirmation requested by your bank, or try another payment method available in your country, such as PayPal where supported.
5. Check the internet connection and temporarily pause any VPN, firewall, ad blocker, or DNS filter that could interfere with Google Play.
6. Enable automatic date, time, and time zone in Android settings, then restart the device. If the values were already correct but validation still fails, briefly set an obviously incorrect time, then immediately restore the correct automatic date, time, and time zone before restarting.
7. Update the Google Play Store from Play Store > Profile > Settings > About > Update Play Store, then retry the purchase.
8. If the Play Store purchase dialog fails during biometric confirmation, toggle the Play Store Biometric verification setting, return it to its original state, then retry. See Google’s purchase verification guidance.

Some devices include a vendor-installed or uncertified version of Google Play that cannot use current Google billing services reliably. Check Play Store > Profile > Settings > About > Play Protect certification. If the device is not certified, see Google’s guidance for uncertified devices.

If a vendor-installed Play Store is too old to update through the normal action above, it must be updated before current Google billing libraries can work. As a last resort, APKMirror provides Play Store packages, but it is a third-party source. Confirm that any package is compatible with the device before installing it.

A completed Google Play purchase is not recognized

First confirm that the purchase completed

Check your Google Play order history while signed in with the purchasing account. If there is no completed Symfonium order with an order number using the GPA. prefix, there is no license for Symfonium to restore. Resolve a pending, cancelled, or missing transaction with Google Play first.

Symfonium periodically validates the license online when it is launched. The device must be able to reach Google Play and the Symfonium validation service.

1. In the Play Store, select the Google account that purchased the unlocker.
2. Open the Symfonium purchase page and select Restore license.
3. If Symfonium remains locked, select Purchase Unlocker once. This asks Google Play to return the current ownership state. If Google Play reports that the item is already owned, restart the device and use Restore license again.
4. A recent purchase can occasionally take up to a few hours to become available across devices. If the completed order is visible, restart the device and retry Restore license later.
5. Ensure Symfonium itself has unrestricted network access and is not blocked by Android per-app data settings, a firewall, or a security application. Then open https://genimee.com/test in a browser on the device. It must display OK. If it does not, temporarily disable any VPN, firewall, ad blocker, private DNS, or security filter and test again. Once it displays OK, return to Symfonium and retry Restore license.
6. Complete every relevant Google Play check from the previous section, including App data sync when available, automatic date and time, biometric verification, the Play Store update, and Play Protect certification.

Multiple Google accounts or installation from another account

When several Google accounts are present, Google Play may not return the purchase if Symfonium was installed through a different account. If the steps above do not restore the license:

1. Create a Symfonium backup and export the backup file outside the app before uninstalling. See Backup & restore.
2. Uninstall Symfonium. This removes its app data and locally stored offline content from the device.
3. Open Google Play on the web while signed in with the purchasing account, then install Symfonium remotely on the correct device.
4. Open Symfonium and use Restore license.
5. After the license is recognized, restore the backup exported from Symfonium if needed.

Restored Android app data

Restoring the complete app and its internal data with an Android backup tool can restore stale license information and trigger additional verification. Before reinstalling, create a Symfonium backup and export the backup file outside the app. See Backup & restore.

Reinstall Symfonium from Google Play, then restore only a backup created and exported through Symfonium itself.

Google Play modification or purchase-emulation tools

Tools such as Lucky Patcher can modify Google Play billing and prevent valid purchases from being returned to Symfonium. Disable and revert all in-app purchase emulation changes. Uninstalling the tool alone may not undo changes it previously applied.

Ko-fi licenses and device changes

Ko-fi licenses are intended for devices that do not include Google Play.

All Ko-fi license handling must be done through a private message on Ko-fi. This includes the initial activation, questions about an existing license, and every migration after changing device, installing another ROM, or factory-resetting the device. Do not use the public support forum or public Ko-fi comments for these requests.

Your trial/device ID is shown at the bottom of the Symfonium license screen. It depends on the device and ROM, so changing device, installing another ROM, or factory-resetting the device can generate a new ID.

Send a private message on Ko-fi with:

• Your Ko-fi username
• The current trial/device ID for an initial activation
• Both the previous and new trial/device IDs after a device, ROM, or factory-reset change

Every device ID change requires a new private message so the license can be migrated manually.

If the ID is shown as Unknown, this method cannot be activated. Use an unmodified Symfonium APK and ensure the device has internet access when Symfonium is first launched, then check the ID again.

Contact support

All required information must be included

Contact support only after completing every relevant troubleshooting step. For a technical Google Play license issue, support cannot locate the purchase or investigate the validation attempt without all the information listed below. Incomplete reports may be closed because there is not enough information to take action.

Declined, pending, or cancelled Google Play payments must be resolved through Google Play. Refund requests follow the refund process described above and do not require diagnostic logs.

For a technical Google Play activation or validation issue, all of the following are required:

• The GPA. order number and purchase date
• The exact error message and the approximate time it occurred
• The result of every relevant troubleshooting step on this page
• Your device model, Android version, and Symfonium version
• Fresh logs: enable Debug mode, reproduce the validation error using Purchase Unlocker or Restore license, disable Debug mode, then share the logs immediately
• The exact description used when sharing the logs

Support cannot investigate the issue without every item above.

For a technical Google Play activation or validation issue, once everything is ready, open the root Settings page in Symfonium, select Contact support, and choose the email option. Send the message from the email application opened by Symfonium and include every item above. Do not use the public forum for license issues. Email keeps the order information and other private details out of a public topic.

Never include card details or account passwords in the email.
