In common with most modern BlackBerry devices, the BlackBerry Curve has a hidden “self-test” application. This is not to be confused with the diagnostic test found on the BlackBerry button menu, in the Mobile Network section of the Options, which tests the device’s network connections.
To access the Self Test from the home screen, press the BlackBerry button to open the Applications menu, then scroll to the Options icon and select Status from the list. The hidden application can then be activated by typing in “test.” If you’re doing this on a BlackBerry Pearl the test is accessed using the multi tap input system, numerically 21?2.
To configure and start the tests, press the BlackBerry button and choose “Start.” You can then select the test options you want to run from:
Keyboard and Trackball
If you want to test Bluetooth or GPS options, ensure these are switched on, on your device first. Having chosen your options, click on the run button using the trackball. The screen will list the test to be performed, the user input required and the expected output for a successful test.
Keyboard and Trackball
Consists of Keyboard Test and Trackball Test. During the keyboard test, pressing any key will cause that key to display on the screen. When you have finished testing the keys, end the test by pressing the trackball, and you will be prompted to move onto the next test, and asked if the test was successful.
To test the trackball, slide your thumb over the square trackball button in all directions and press and release. Pressing any key during this test will prompt you to end the test and move on.
The miscellaneous section includes a Light Sensor Test which displays the light detected on screen. Although no user input is required, if you want to test this, hold your hand over the screen or move the device closer to a light source and watch the numbers change.
The keypad back light test turns the keypad back light on after a single key press. If you conduct this test in bright light, you may need to cover the keypad to verify this.
The LED Test cycles the LED light from red to green to blue then off again with successive key presses.
The LCD Backlight Test will toggle the LCD screen and keypad lights on and off, so don’t panic when you press the key the first time and your screen goes black. A second key press will bring it back on again.
LCD Pixel Test allows you to check for damaged individual pixels on the screen. Consecutive key presses will turn the screen red, green, blue and ten white with the test screen flashing up between each screen, allowing you to exit the test.
The Vibrator Test toggles the vibrator on and off.
The Holster Detect Switch Test requires you to slide the device in and out of the holster, and check the actions are reflected on the screen. Since the screen can’t be checked inside the holster, a visual confirmation is supplied. The LED light toggle between red when the phone is in the holster and green when it is not.
This consists of Handset Speaker, Handsfree Speaker and Handset Microphone tests. The two speaker tests cycle through a series of tones emitted from the relevant speaker, increasing in pitch from a dull low tone to a high pitched one. The Microphone test simply requires you to press any key and make some noise for five seconds, at which point the recorded audio will automatically be played back to you.
This tests the devices’ ability to detect connection and disconnection of a wired headset, then tests the speakers and microphone on the headset.
Repeats the Speaker and Microphone tests sending the output to a connected Bluetooth device. If you need to reconnect your Bluetooth device at this point, you can do so by pressing the Alt and Escape (that’s the curved arrow at the side of the trackball) keys together. This will take you to the Bluetooth Connection screen where you can pair the headset with your device, and return to the Self Test by pressing the Alt and Escape keys again.
The RF Antenna Test requires you to place a call, and measures the frequency. Once the call is connected and the frequency updated, you can disconnect.
To test your device’s GPS connection, you will need to be outdoors. Start the test by pressing the BlackBerry button and choosing the “Start Fixing” option. The screen will update as satellites are found if successful.
Having completed all the selected test options, you will be returned to the Self Test start screen, and a log will appear with the results of the tests. Although these tests may be useful when considering purchasing a second hand or reconditioned device, remember that the pass/fail results are reliant on user input, so it is better to carry out the tests yourself than rely on the existing logs of previous tests.
