View the Full FAQ (Chinese)What is the difference between NOTE4 and NOTE4C?
NOTE4 is a ready-to-use consumer product with official firmware and AI voice task features. NOTE4C is a four-color open development device designed for developers, and it does not include NOTE4's ready-to-use NOTE4 features.
What should I do if NOTE4 cannot connect to the network?
Confirm that you are using 2.4 GHz Wi-Fi, then check the network name, password, and provisioning steps in the Quick Start Guide. If the issue continues, submit feedback in the mini app under Me > Feedback.
Is screen flashing during a NOTE4C refresh normal?
Yes. A full refresh on a four-color e-paper display takes time and may flash, briefly invert colors, or flicker during the refresh.
How do I check or update the firmware?
Open the Wiki release notes and the documentation for your product to find the current version, update requirements, and step-by-step instructions.
What should I include in a support request?
Include the product model, device information, steps to reproduce the issue, and any relevant screenshots or video.
