Email is our support channel. ZuiHub Kid is made by an independent developer. We read every message and answer by email as soon as we can. You can write in Vietnamese or English.
What to put in your message
- The devices you play on: the model of the TV or TV box and the model of the phone.
- The Android or iOS version, and the app version if you know it.
- What you did, what you expected and what happened instead. A photo of the TV screen helps.
- For a connection problem: whether the TV and the phone are on the same Wi-Fi network.
Please do not send personal details about your child, such as a full name, a date of birth or photos. We do not need them to help you.
Common questions
The phone cannot connect to the TV
- Put the TV and the phone on the same Wi-Fi network. The phone must use Wi-Fi, not mobile data. Guest networks often stop devices from reaching each other.
- Open ZuiHub Kid on the TV first. Its home screen shows a square code (QR).
- In the phone app, tap “Scan the code on the TV” and point the phone at that code.
- Choose Allow when the phone asks for the Camera. On iPhone, also allow Local Network. If you refused earlier, turn them on in the phone's Settings, in the entry for ZuiHub Kid.
- If scanning does not work, tap “Type the code” and enter the digits shown under the code on the TV.
- Still stuck? Close the app on the phone and on the TV, open both again, and restart the Wi-Fi router if needed.
I scanned the code with the phone's camera and a web page opened
That is normal. The code on the TV is made for the ZuiHub Kid app. Install the app, open it, and scan the code from inside the app. The page Connecting the phone to the TV shows the steps.
The TV went to sleep or the phone lost the connection
Wake the TV and open ZuiHub Kid again, then open the app on the phone. If the phone does not reconnect by itself, scan the code on the TV again. The phone remembers your child's animal friend.
There is no sound
Music, voices and sound effects come from the TV, not from the phone. Check that the TV is not muted, turn the volume up, and check the sound output in the TV's settings if you use a soundbar or a Bluetooth speaker. The phone only vibrates gently.
How do I change the language?
The app starts in the language of the device and is available in Vietnamese and English. To change it, use the language switch on the TV home screen; the phone follows the TV once it is connected. This website can be read in six languages: use the language menu at the top of the page.
Which devices are supported?
- Screen: a TV or TV box with Android TV or Google TV, Android 7.0 or newer.
- Controller: an iPhone with iOS 16 or newer, or an Android phone with Android 7.0 or newer. Each player uses one phone.
- Network: one home Wi-Fi network shared by the TV and the phones.
Some games can also be played with the TV remote alone.
Where can I get the app?
The ZuiHub Kid app is coming soon to the App Store and Google Play. The download buttons will be here when it is released.
Is it free? Are there ads or purchases?
ZuiHub Kid is free. It has no ads, no in-app purchases, no account and no sign-in.
Does the app need the internet?
Playing only needs your home Wi-Fi. When the TV is online, it downloads new question sets by itself; offline, the games use the questions built into the app. The phone app does not use the internet.
How do I delete the app's data?
We hold no data about you on any server. What the app remembers is on your own devices. On Android TV, Google TV and Android phones: open Settings, Apps, ZuiHub Kid, Storage, and choose Clear data, or uninstall the app. On iPhone: delete the app.
How does my child play safely?
Clear a space around the child, have the child hold the phone firmly with both hands, use only the gentle moves the game shows, and keep an adult nearby. See Play safely in the terms of use.
Privacy questions and requests
The app collects no personal information, so we hold no data about you or your child. If you are a parent or guardian with a question or a request about privacy, write to hieupv.est@gmail.com and put “Privacy” in the subject line. The details are in the Privacy policy.
