Hello Jolla Enthusiasts. Like the Nokia phones, the Jolla device has a secret utility called CSD Tool, enabling the users to test a bunch of features and diagnose their phone easily.
Among others, the following can be tested via the CSD Tool: 2G/3G and GPS, display, multitouch, contrast, audio input and output, front and rear camera, NFC, bluetooth, battery state, vibrator, compass, SIM card and microSD card, physical keys and LED notification.
To enter the testing app, you can either type *#*#310#*#* on the phone’s dialler, or type csd in the terminal, while you are in the developer mode.
For those who don’t know yet, Jolla is a project developed by former Nokia employees. The first Jolla smartphone is running on Sailfish OS, a modified Megoo Linux system, which is Android compatible, uses Wayland as the default display server , uses Nokia N9′s Maliit touchscreen keyboard and comes with interchangeable covers, allowing the users to easily switch them, in order to change the color/model of the phone and comes with impressive hardware specifications. Apps can be installed via the Jolla Store, which will provide both Jolla and Android apps, or via F-Droid, Yandex Store, Amazon App Store, Aptoide and 1Mobile Android Market.
