I'm a Volla 22 user, now evaluating and testing the device. A few apps require Google services installed to work properly, especially banking ones. Even creating a separate user profile to handle it, and as a sandbox isn't on it, the Volla OS generates an error: “There was a problem parsing the package”.
This means possible a Volla OS restriction somehow. How do you guys deal with this particular thing? I was able to install the gsm and gfm apk packages separately but the apps suddenly load and crash.
