If you are not sure whether you need to send in your device or if you can fix the problem yourself, just consult the Cyrus FAQ. If your question is not covered there, feel free to use the support form. Customers in Germany can send the complaint to the company's own service workshop in Aachen:

Cyrus Technology GmbH
Hergelsbendenstraße 49
52080 Aachen

Your submission must include three things:

• The defective Cyrus Phone
• A copy of the invoice
• The completed repair order

Please send a package only with complete information - unfortunately, an incomplete submission will significantly delay the repair process.
It is not necessary to send other accessories such as power supply, USB cable, etc., if they are not included in the complaint or could be affected by it (e.g. the USB cable in case of charging problems).

Your device will be registered upon receipt of goods. If you have entered an e-mail address in the repair order, you will be automatically informed about the receipt of the goods and the expected processing time after registration. If there are any questions or additional costs, an employee will contact you beforehand. After the repair you will receive your device back automatically.

Cyrus recommends, if possible, to make a data backup before sending the device.

• Backup with external software: Managing a device with external software is particularly suitable if you want to manage multiple devices or simply always have an overview of your own data. Programs for this are available in the Google Play store. The use of the programs is usually described by the providers of the app.
• Backup with a micro-SD card: Backing up your data (not the phone contacts) can be done via the installed File Explorer/File Manager. Here you can see all available data carriers and manage the data accordingly. For example, if you want to copy, cut or delete an item, tap and hold the file(s). Then select the corresponding option.
• To backup phone contacts, there is an "Import/Export" option in the Contacts app. First, tap and hold to highlight the contacts you want to export, click the menu at the top right of the screen and select "Import/Export". Now you will be asked for a source. Here, select "Phone" and then "Next". After that, you will be asked for the destination. Select the inserted micro SD card here and confirm with "OK". A message should now appear informing you that the contacts are being exported. You can see the progress of the export in the notification bar.
• Backup via email accounts (cloud): The backup here is usually done via synchronization with a previously created account. If you have not created an account, please add one first: You can add a new account of the desired type via Settings/Account. Once the account has been set up with the correct credentials, it is linked to the device. In the options of the deposited account, you can select the content to be synchronized. Now, if an account has been deposited there and the synchronization of contacts has been ticked, the contacts should be synchronized.

To back up the rest of the data on your device, most email providers offer cloud storage. An app to link the storage is often offered as well. In that case, search for the app in the Playstore and set up your access with the required credentials. As soon as the link is established, you can make settings for synchronization here as well.
