Why is my AR content shaking or shifting?
The reason for the shaking or shifting of the AR experience content is related to the phone’s temporary memory and computing power.
If your experience screen appears to be lagging and the AR content is drastically shaking, it is recommended that to close other apps before experiencing AR as this may improve your experience.
Why can't I find the AR content even though already in camera mode?
Please rotate 360 degrees to check whether the AR content is in the space near you or behind you, if there is no AR content at all, it may be due to the following reasons:
(1) Tentative memory overflowing: Close the other app or reopen the phone to improve the situation.
(2) Device memory is too full: your phone has too many photos, videos, apps, so that the capacity is overloaded, if this is the problem, you will need to delete some of the content in your phone.
Suggested way to rule out:
First close the temporary memory of the experience (IOS is to close all windows by tapping the Home button twice or pulling up, Android is to close all windows by tapping the lower right corner), if it still can’t be improved, it can be initially determined that the memory of the personal device is overfilled, and we suggest that the experience user can delete some apps or videos and photos that can’t be used.
If it still can’t be experienced, that would be a specific case problem, please provide us with the phone info for further research.
How can I take pictures and record of the AR experience?
You can use “Camera” to take photos during the AR experience, or click the “Record” button to switch to recording mode. The photos and videos will be automatically saved to your phone’s photo album.
Can I use the front lens to take a selfie with the AR?
At present, HoloRoam APP is mainly used to calculate AR experience through the rear lens of the mobile device, and the experience related to the front lens is not yet released.
Why do I take multiple photos and only save the last one?
Initially, it may be due to hard disk space limitations. It is recommended that you close all other applications on your phone and reopen HoloRoam if you encounter this situation.
