The Volla OS offers several ways to install Android apps. We recommend three variants:
All apps that are compatible with Android 9 and do not rely on Google Play Services. Also, apps that require extensive root privileges cannot be installed by default for security reasons.
You can still use some apps that require Google Play Services with limited features.
To protect the privacy and data of Volla Phone users, the Volla OS does not receive Google Apps and Play Services.
Ubuntu Touch uses its own pre-installed Open Store, which contains apps developed for the Linux mobile operating system.
Users experiencing difficulties with the Aurora App Store on the Volla OS are advised to check the following settings:
Failure to search for apps.
Aurora is becoming more and more popular. Therefore, when using an anonymous account, searching for apps may result in a notice that the number of possible requests has been exceeded (rate limit). In this case, proceed as follows:
Go to the System Preferences app, then "Apps and Notifications", "Show all ... apps", "File Manager" and "Permissions". Finally, enable the setting for "Storage."
Connect the Volla Phone in a switched on state with the supplied USB cable to the supplied power supply. The Volla Phone can be in standby mode or can be put into standby mode by briefly pressing the power button, which will turn off the display but not the device.
If "Bootloader" is displayed in small letters in the lower left corner after you have connected the Volla Phone to the charger, you must first turn it on and then reconnect it to the charger.
If the battery is completely empty, please proceed as follows:
If the device does not start in the second step, repeat the first step.

You can find a more advanced user guide for Ubuntu Touch on the Ubports Foundation website, which continues to develop Ubuntu Touch with a community of developers.
This is done in two ways:
You can send and receive MMS with the Messages app. This function is available as soon as you have inserted your SIM card and activated it with your PIN code. Prerequisite is that your contract includes a data package and you are in a radio cell that supports the frequency range of the Volla Phone.
If you have problems with sending and receiving MMS, check the network settings.
The mobile internet connection is available as soon as you have inserted your SIM card and activated it with your PIN code. Prerequisite is that your contract includes a data package and you are in a radio cell that supports the frequency range of the Volla Phone.
Make sure that you have activated the network connection. To do this, call up the system settings and select "Network". There the settings "Mobile data" must be activated and if you are abroad also "Data roaming".
If you have problems with Internet access, check the network settings.
The UBports Installer allows you to install the Ubuntu Touch, Volla OS and Sailfish OS operating systems on the Volla Phone. Since the app is only available in a beta version and in some cases the Volla Phone has to be unlocked first, we only recommend changing the operating system to experienced users.
The Volla OS shows the contacts that you have marked as a favorite in the Contacts app or that you have been in contact with via a call or message in the last few days.
The contacts in the Contacts app must also be stored in the phone memory. When importing from an address book file, make sure the location is "Phone".
The Volla OS offers the call of news on the springboard. Users can include additional news channels that are published in RSS format. There are two ways to do this:
Atom or RDF feeds are not yet supported.
You can insert a MicroSD cart into the second slot of the sled, where you also insert your SIM card for the Volla Phone. The slot is easily recognizable by its larger width.
The SD memory card can have a capacity of up to 256 gigabytes. User tests with memory cards up to 512 gigabytes were equally successful.
A Volla Phone with Volla OS can also format the memory card. Note here that you always set up the memory card as external memory, never as an extension of the internal memory. The latter can lead to errors when running apps.
Note for Ubuntu Touch that the memory card must first be formatted on your PC or Mac according to the FAT32 standard. Otherwise formatted memory cards cannot be read by the system or lead to an unstable connection.
In some cases, the Volla Phone X displays only 8 GB instead of 64 GB of storage after the first start. You can get the full memory capacity by resetting the device to factory settings. Proceed as follows:
You can import contacts with phone numbers you had stored on a SIM card to a Volla Phone with Volla OS to use them in Springboard, for phone calls and in other apps.
