Common Problems and Frequently Asked Questions

I don't find the WowBox on my GoFox F15.
The WowBox is an app by Grameenphone (Telenor) and so you have to use a GP SIM to use this app. That means you must have an active GP SIM inserted into the GoFox F15 device to use the wonderful features of WowBox.
I want to hard reset my device as I have found this option for some other Firefox OS devices on MDN.
Unfortunately, there is no hard reset option for the GoFox F15. But you can reset it from the Settings App and debug it using adb on Linux/Mac.
I have turned on the Screen Reader on my GoFox F15 and my touch is working differently to how it did before.
You can set it back to normal in different ways: using the volume keys, or manually using screen reader gestures designed for blind people.  Both of these options are described below.

Controlling the screen reader

This section covers some options for controlling the screen reader.

Screen reader basic gestures

The following are the basic screenreader gestures for manual control, known as the gestures for blind people:

  • Select something with Long Tap : To select any app or object on the content view area, use Long Tap. Long Tap means holding down a tap for a while till the object gets selected.
  • Activate something with Double Tap : To activate or enter into an already selected option, app or object, use Double Tap.
  • Move the selection left with Swipe Left : To change the position of the current selection from right to left use Swipe Left.
  • Move the selection right with Swipe Right : To change the position of the current selection from left to right use Swipe Right.
  • Performing a swipe with Two Fingers Swipe : To swipe use Two Fingers Swipe. The direction will be your desired direction. This is used to scroll in any direction or flip the horizontal screen. You have to do it very carefully, keeping one finger on the currently selected object and the other somewhere else and in parallel to the first finger. Have a look at the video below:

For this you have to select the last object in your desired direction first. So, if you want to swipe left, you have to select the rightmost object. Select the leftmost object for swiping right, bottommost for swiping upwards and topmost for swiping downwards. The following screens explain these:

Turning off Screen Reader using volume keys

Press volume up, then down, three times (up, down, up, down, up, down). The screen reader will instruct you to perform this same action again (volume up, down, up, down, up, down) to turn it on if it is not running, or to turn it off if it is already running. If you do not want to change the current toggle state, simply do something else.

Manually turning the Screen Reader off

  1. After reading the above section to learn the gestures, follow the steps in this section to manually turn off the screen reader:
  2. First, restart your device.
  3. Next, select any of the objects on the lockscreen using a Long Tap and then select the unlock button on right bottom of your screen by using Swipe Left.
  4. Double Tap anywhere on the screen to activate the unlock button. You should now be on the home screen.
  5. Use Two Fingers Swipe to flip the screen/scroll horizontally.
  6. Select the last app on the screen by using Long Tap or Swipe Left gestures.
  7. Now use Two Fingers Swipe as described above — you should be on the next screen.
  8. After that, select the Settings app and activate it using the same selection procedure described above. Closely look at the placement of your fingers while doing the Two Fingers Swipe.
  9. Stop the Screen Reader by following the steps in the images below:      

Debugging on Linux / Mac

  1. Open up a Terminal, and issue the following commands.
    mkdir ~/.android
    echo "0x1782" > ~/.android/adb_usb.ini
  2. Restart adb server.
    adb stop-server && adb start-server
  3. Linux users need to add an extra udev rule by issuing the following command as root.
    echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="1782", MODE="0666"' > /etc/udev/rules.d/51-android.rules
