Rear camera doesn’t work any more after sleep mode
When the rear camera has been used or in some files the camera page has been opened in ME4, and then the device goes in sleep mode, the rear camera will no longer function after resuming from sleep. A black screen will be shown instead of the camera window. That is a bug in Mind Express 4.
As a workaround, after resuming from sleep, you can toggle the camera to the front camera, then return to the rear camera. Or you can restart ME4.
SMS/GSM/BT options
An overview of the options can be found here.
Making phone calls using Mind Express 4
You will need to install a third party app called “CallCenter” to make phone calls.
You can try the app for 15 days, and/or buy a license for 13.5€.
Please read this document for a detailed procedure.
Text messaging won’t work properly using the CallCenter app.
Text messaging using Mind Express 4
Connect your smartphone to the Vibe, using the default Windows BlueTooth connection procedure.
Then, in the Mind Express menu, select “Extra” > “Phone” > “Model: Bluetooth Smartphone”.
You are now able to send and receive text messages in Mind Express.
Making phone calls is not possible using this option.
Screen rotation
To rotate the screen in Windows, go to Windows “Settings” > “System” > “Display” and choose your display orientation.
Microphone isn’t working properly
Make sure the microphone isn’t covered by the protection cover. The microphone can be found in the middle of the right side of the screen edge. It is a tiny hole right next to the screen edge.
Power button behavior
You will need to press and hold the power button for 2 seconds to start the device. When the device is connected to a charger, then a short press will show the battery status. Also, if the device is in sleep mode, a short press will wake up the Vibe.
Sleep mode is not available
Your graphics card model should be indicated as “UHD Graphics 605” and not “Microsoft Basic Display Adapter” or other. We recommend to update your graphics card to the latest version. You can either download the driver directly from the Microsoft website, or you can download it here.
Can’t wake up from sleep mode
It is not possible to wake the Vibe from sleep mode using the touch screen. Use the power button (short press) instead.
BIOS update message pops up
If a BIOS update message pops up on the Vibe, you can either refuse or agree, both options are fine. If you refuse, nothing will happen. If you agree, then a quite complex (but straightforward) procedure will start, including a download, a few restarts and a DOS utility for flashing the BIOS. The procedure takes about 5 minutes.
You can also download the latest BIOS update from the Downloads section and start it immediately.
To avoid future BIOS update messages, you can choose to uninstall the “Lenovo Welcome” and the “Lenovo Vantage” store apps. Click on “Start” and locate both programs in the list. Right-click on them and choose “Uninstall”. However, we can’t guarantee that the apps won’t be reinstalled with new Windows updates.
Passwords
If a password is requested, try “vibe”. If you are asked for security questions, try as answer “jabbla”.
Disable/enable the Escape button
You can disable the Escape button on the back of the device. Please check the downloads section for a package containing 2 REG files, which will allow you to toggle between both states (disable/enable). Double-click the desired REG file and the information will be added to the Windows registry. Reboot afterwards.
Note: this feature requires the latest version of Mind Express 4 (v4.4.3.2291 or higher).
