Samsung - Android (6.X)

The Tecla Shield is also compatible with Samsung devices that have the Universal Switch accessibility feature. Check if your devices is compatible by going to Settings> Accessibility> Dexterity and Interaction and see if the Universal Switch feature is available.

To start your Tecla Shield should be in Switch Access / Switch Control Mode (Blinking purplish white). If you are not sure how to change modes check here: Mode Change Instructions

With the Tecla Shield ready for connection – the status indicator light should be blinking white and the switches should be connected to it - follow the steps below to set up your Android device with Universal Switch.

1. Pair your Tecla Shield: Go to Settings > Bluetooth. With Bluetooth enabled, you should see the Tecla Shield DOS listed under Available devices as TeclaShieldDOS-XXXX (where XXXX is a random sequence). Click on it. After a few seconds, TeclaShieldDOS-XXXX should be under Paired Devices and appear as Connected.

                            

2. Set up a Smart Lock: Once the Tecla Shield is connected, you can set it as a trusted device. This will keep your device unlocked as long as the Tecla Shield is connected to it. If you have a screen lock type (i.e PIN, Pattern, Password), go to Settings > lock screen and security > Secure lock settings > smart lock. Enter the screen lock type that your phone has set up. Then select Trusted devices > Add Trusted Device > Bluetooth. Select TeclaShieldDOS-XXXX as your trusted device.

3. Set-up Universal Switch: Go to Settings > Accessibility, then select Dexterity and Interaction > Universal Switch. Click on Settings.

                      

                      

4. Assign your switches to actions:  If you are using single-switch access, make sure Auto Scan is on. To set-up your switch Go to Switches > Add a Switch. 

  

5. Select Accessories. You will be prompted to press your switch at this point. Press a switch connected to the Tecla Shield. In the New Switch pop-up window write the name of the switch and press Save.

  

6. If you are using a single switch (or you are using more than one switch, but this is your main selection switch), choose the “Select Item” action. Check the Note  section below for a brief description of other possible switch actions that you can assign to switches. The Recommended Configurations (table 1 & 2) may also be helpful for assigning switch actions.

                                   

7. Repeat steps 4-6 for all your switches. For possible combinations check the Recommended Configuration section below. 

8. Select item mode scanning: on the Universal Switch settings page, go to Scan Method and Select Row. 

                                   

9. Ensure On-Screen Keyboard is shown: Go to System > Language and input > Default Keyboard. Make sure you have Samsung Keyboard as your selected keyboard.  

  

 10. Enable Switch Access: Go back to Universal Switch, and activate Switch Access by clicking on the on/off control. At this point, you should be able to control the Android using the Switch Control through the Tecla Shield. When you pressed any of your assigned switches you should see a frame around the user interface.

Recommended Configurations:

Switch Actions -

• Select item – pop-up action menu related to selected item or location
