Hi, thank you for explaining what you have already tried. I’m sorry the printed instructions don’t match the screens you see, and that you haven’t been able to connect.
5D Holo is the correct iPhone app for the F1. To help narrow down the issue, could you please check these two things?
In iPhone Settings → Wi-Fi, is your phone connected to the fan’s own Wi-Fi hotspot, rather than your home Wi-Fi?
In Settings → Privacy & Security → Local Network, is 5D Holo listed, and is its access enabled? If the app is missing from that list, please let us know.
You can also watch our 5D Holo mobile app tutorial for a visual reference:
The app interface is introduced at 0:33. Menus may differ by app version, so please tell us where your screen differs from the demonstration.
You don’t need to repeat the restart steps you’ve already tried. If the connection and permission checks are already correct, please send a screenshot of the app’s connection message and your app version. Please hide passwords and personal information.
If you prefer to share screenshots privately, please email our MISSYOU after-sales support team at hihologramfan@gmail.com. Include your fan model, app version, and a screenshot of the connection message so we can assist you further.
We understand your question about returning the device. We cannot yet determine whether the fan is faulty, but we’ll help you work through these checks and clarify the appropriate next step, including your return question.
