This is the current list of known HoloLens bugs and issues that affect developers and end users. This list will stay updated when additional issues discovered or reported, or when issues addressed in future HoloLens software updates.
Microsoft hololens Wi-Fi connection
During OOBE & Settings, there are only 2 minutes to enter the username and password. If it takes 2 minutes and you do not enter details, the username will automatically clear.
We recommend using the Bluetooth keyboard to enter long passwords.
Umicrosoft hololens pdate device
30 seconds after a new update, the mantle will disappear once, perform the rash movement to resume activation.
Microsoft hololens Visual Studio
Update and download a new version of the tool for the latest version of Visual Studio recommended for HoloLens development.
When deploying an application from Visual Studio to your HoloLens, you may see the error: they cannot perform the requested operation on a file with a user-mapped section open. (Exception from HRESULT: 0x800704C8). If this happens, try layout again and everything will work out again.
microsoft hololens Emulator
Not all applications in the Microsoft Store are compatible with the emulator. For example, Young Conker and Fragments are not playable on the emulator.
The emulator's PC camera cannot used.
The Windows Device Portal Live Preview feature does not work with the emulator. But you can still capture mixed reality videos and photos.
microsoft hololens unity
See Install the tools for the latest version of Unity recommended for HoloLens development.
I can find known issues with Unity HoloLens on the other HoloLens forums.
Microsoft hololens Windows Device Portal
The live preview feature in mixed reality view may display a few seconds of latency.
On the Virtual Input page, the Gesture and Scroll controls in the Virtual Gestures section are not functional. Using them will have no effect. The virtual keyboard on the same page works properly.
After enabling Key Mode in settings, it may take a few seconds for the switch to activate the device portal.
microsoft hololens API
If the application sets the focus point behind the user or normal to camera.forward, holograms will not appear in mixed reality in capturing images or videos. Until we fix the bug fix in Windows, if applications actively set the focus point, they should make sure that they set the normal in front of the camera forward (for example, Normal = -camera.forward).
Xbox Wireless Controller S Wireless Controller
We must update the Xbox Wireless Controller S before we can use it with HoloLens. Make sure you are up to date before trying to adjust the controller using HoloLens.
If you reboot your HoloLens when the Xbox Wireless Controller connected, the controller will not automatically reconnect to HoloLens. The guide button light will blink slowly until we stop the controller after 3 minutes. To reconnect the controller immediately, turn off the controller by pressing the Guide button until the LED turns off. When you turn on your controller again, you need to reconnect to HoloLens.
If the HoloLens goes into standby while we connect the Xbox Wireless Controller, any input on the controller will wake the HoloLens. This can prevented by turning off the controller when you did using it.
Microsoft holo lens My HoloLens is not responding or not starting
If the LEDs on the power button are off, or one LED is blinking briefly, you may need to charge the HoloLens.
If the LEDs light up when the power button pressed but nothing is visible in the displays, hold the power button until all 5 LEDs are off.
If your HoloLens frozen or unresponsive:
Turn off the HoloLens by pressing the power switch until all 5 LEDs are off. If this does not help press for 10 seconds, if the LEDs do not respond. Press the power button again, to boot.
Microsoft holo lens If it doesn't help:
You can try restoring your device.
The holograms do not look good or turn around.
If your holograms are unstable, bouncy or don't look right, try:
Clean the device protector and make sure nothing is blocking the sensors.
Make sure there is enough light in your room.
Try turning around and looking at your surroundings so that HoloLens can scan them better.
Try running the calibration app on HoloLens Use your eyes. Go to Settings> System> Utility. Under Calibration, select Open Calibration.
If you are still having problems after starting the Calibration application, use the Sensor Tuning app to tune the device sensors. Go to Settings> System> Utility. Under Sensor Tuning, select Open Sensor Tuning.
HoloLens does not respond to my gestures.
To make sure HoloLens can see your gestures, keep your hand in your field of vision, which spans a few feet on each side of you. When HoloLens sees your hand, the cursor will change from point to ring. Learn more about using gestures.
If your environment is too dark, HoloLens may not see your hand, so make sure there's enough light.
If your face protector has fingerprints or stains, please use the Microfiber Cleaning Cloths that come with HoloLens gently clean the sun visor.
HoloLens does not respond to my voice commands.
If Cortana does not respond to your voice commands, make sure it enables Cortana. In the list of applications, select Cortana> Menu> Notebook> Settings to make changes. To learn more about what you can say, see Use your voice to control HoloLens.
Microsoft hololens I can't place the holograms or see holograms I put in earlier.
If HoloLens cannot map or load your space, it will enter a restricted state and you cannot place holograms or see holograms you placed. Here are some things to try:
Make sure there is enough light in your area so HoloLens can see the map and map.
Make sure you're connected to a Wi-Fi network. If it does not connect you to Wi-Fi, HoloLens cannot identify and claim a known area.
