Viwoods devices offer different screen orientation options depending on the product series. For the AiPaper series, landscape mode is available in the Learning section. Open Learning, then use the menu bar to switch between portrait and landscape reading modes. The AiPaper Reader series supports system-wide screen rotation. Please note that the AiPaper series does not include a built-in G-sensor. If you would like to enable automatic or system-wide screen rotation, you can use a trusted third-party orientation app, such as Set Orientation.

E Ink displays use a different refresh mechanism from LCD or OLED screens. During page turns, scrolling, or other screen changes, faint traces of previous content may temporarily remain visible. This is commonly known as ghosting and is a normal characteristic of E Ink display technology. To reduce ghosting, use the screen refresh function and allow the display to complete a full refresh. If the traces remain clearly visible after refreshing, become unusually strong, or persist in the same area of the screen, please contact Viwoods Support and provide a short video showing the issue for further review.

Battery consumption can vary depending on how your device is used, including Wi-Fi and Bluetooth activity, cloud syncing, background apps, screen refresh frequency, and front-light use where available. For reference, the Viwoods device supports up to one week of daily use based on 2 hours of use per day, or up to 4 weeks on standby. Actual battery life may vary depending on usage.

• Turn off Wi-Fi or Bluetooth when they are not needed.
• Reduce unnecessary background syncing and close unused apps.
• Lower the front light when possible on models that support it.

If the battery continues to drain unusually quickly during light use or standby, contact Viwoods Support for further assistance.

If your Viwoods device is lost or stolen, please contact Viwoods Support as soon as possible.

• To verify ownership and confirm your order, please provide proof of purchase from an official Viwoods sales channel, the original product packaging showing the device serial number (SN), and a brief description of what happened.
• Our support team will verify the information and provide a Device Lock Confirmation Form.
• After you confirm and sign the form, we will submit a request to remotely lock the device to help protect your personal data from unauthorized access.

If the device is later recovered, contact Viwoods Support again. After verification, we can submit a request to unlock the device so you can continue using it normally.

A Viwoods device may be remotely locked if it has been reported to Viwoods as lost or stolen. This security measure is designed to help protect the original owner's data and prevent unauthorized use. If you believe your device has been locked by mistake, please follow the instructions below based on your purchase situation:

• If you purchased the device through an official Viwoods sales channel: please contact Viwoods Support as soon as possible and provide your official proof of purchase. Our support team will verify the device and purchase information and assist you with the unlock request if the information is confirmed.
• If you purchased the device through a non-official or second-hand channel: please contact the original seller or the platform where you purchased the device and request their assistance in resolving the issue. You may also need the original purchaser to provide valid proof of purchase from an official Viwoods sales channel.

Please note that Viwoods can only process an unlock request after the device ownership and purchase information have been successfully verified.

We're sorry to hear that your device screen has been damaged. If your screen is cracked after an accidental drop, please get in touch with Viwoods Support and provide your order details along with clear photos showing the screen damage. Our support team will carefully review the device condition and confirm whether it is eligible for our paid screen damage service.

• Within 60 days of delivery, you may choose to receive a replacement device by paying the applicable service fee, or return the device for a refund with the applicable service fee deducted.
• After 60 days but still within the warranty period: You may be eligible for a same-model replacement by paying the applicable service fee. The replacement device will be in approximately 90% new condition and will be carefully inspected and functionally tested before shipment.

The original damaged device must be returned as part of the service process. Please do not make any payment until Viwoods Support has reviewed your case and confirmed your eligibility and applicable service fee. We understand that accidents can happen, and our support team will do its best to help you find the most suitable solution.

You can download apps on your Viwoods device through the following methods:

• Download from the Viwoods App Market: Open the Viwoods App Market and search for the app you would like to download.
• Download from Google Play: If the app is not available in the Viwoods App Market, go to Settings → Play Store → Google Service and complete the Google authorization process to enable Google Play. You can then search for and download the app from Google Play.
• Download from an official website: If the app is not available in either app store, you can use Chrome to visit the app provider's official website and check whether a compatible installation package is available.

Please note that the availability and compatibility of third-party apps may vary.

Viwoods AI is designed to support reading, writing, and knowledge workflows directly on your device. You can use it to ask questions, summarize or explain content, translate selected text, work with AI Commands for repeated tasks, and choose from supported AI models. Web Search is also available when you are signed in to your Viwoods account, allowing the AI to access current information when needed. The built-in AI is integrated into Viwoods workflows and may not include every feature available in standalone AI applications. AI capabilities continue to expand through system updates and ongoing improvements.

Viwoods devices support several file transfer methods, including USB-C, email, Bluetooth, Wi-Fi transfer, and cloud services such as Google Drive, Dropbox, and OneDrive. For supported AiPaper devices, you can also use ViTransfer to transfer files between your Viwoods device, computer, and phone.

Viwoods uses multiple measures to help protect your data and account information.

• Local device protection: Your lock screen password is stored locally on the device.
• Secure data transmission: Network data is transmitted using HTTPS encryption to help protect information during transfer.
• Optional cloud synchronization: Viwoods Cloud is turned off by default. You can choose whether to enable cloud sync and which supported apps or content you want to synchronize.
• Account-based data separation: When Viwoods Cloud is enabled, synced content is linked to your Viwoods account, helping keep data from different accounts separate.

You can manage cloud synchronization settings for supported apps at any time based on your needs.

Yes. Occasional screen refreshing is normal for the E Ink display used on your device. Unlike LCD or OLED screens, E Ink refreshes content by updating electronic ink particles, so brief flashes or faint traces of previous content may appear during page turns, scrolling, or other screen changes. Periodic refreshes help clear these temporary traces, often called ghosting, and maintain display clarity. If visible artifacts remain after refreshing or the screen behaves unusually, please contact Viwoods Support.

Viwoods devices use E Ink displays, which are designed to provide a more paper-like and comfortable viewing experience than traditional LCD or OLED tablets. While LCD and OLED screens are optimized for fast animations, video, and highly responsive visual interactions, E Ink is optimized for focused reading, writing, and extended viewing. As a result, scrolling, page transitions, and certain app interactions may feel different from those on conventional tablets. In return, E Ink provides a calm, distraction-free display that is well suited for reading, note-taking, and focused work.

Viwoods devices use an Android-based system, but Google services are not enabled by default. A manual authorization process is required before you can use Google Play and related Google services on your device. To enable Google Play:

• Go to Settings → Play Store.
• Turn on Google Service.
• Tap Go to Authorize and follow the on-screen instructions to complete the authorization.
• Restart your device after the authorization is completed.

If Google Play still does not load or work properly, press and hold the Google Play Store icon, open App Info → Storage & Cache, and select Clear Cache. Then reopen Google Play and try again.

Viwoods AiPaper and Reader series devices do not have built-in speakers. To maintain their ultra-slim and lightweight design, they are not designed for direct audio playback through the device itself. However, Viwoods devices support Bluetooth connectivity, allowing you to connect Bluetooth headphones, speakers, and other compatible audio devices. This lets you enjoy audiobooks and other audio content through connected devices.

Yes. Viwoods AI features require an internet connection because AI requests are processed using connected AI models and online services. AiPaper devices can connect through Wi-Fi, allowing users to access AI-powered features such as AI conversations, content processing, translation, summarization, and other supported functions. Core functions such as handwriting, reading locally stored documents, and basic note-taking can still be used without an internet connection. However, AI features require network access to communicate with the selected AI model and return a response. For the best AI experience, users should ensure that their Viwoods device has a stable internet connection before using AI-powered tools.

Viwoods Cloud is available on AiPaper and AiPaper Mini with system version V3.15. Cloud sync is turned off by default, so you can choose when and what to sync. After enabling Viwoods Cloud, Paper, Meeting, Knowledge Base, Memo, and Daily can be set to sync automatically, with synchronization managed separately for each app. You can also upload selected books from Learning to sync reading progress, bookmarks, highlights, and annotations. Viwoods Cloud includes 10GB of free storage, and your synced content can also be accessed at cloud.viwoods.com.

Paper provides several tools to help you keep notes, notebooks, and pages organized as your content grows. You can:

• Use folders, outlines, tags, and favorites to structure and quickly find content.
• Duplicate notebooks when you want to reuse an existing structure.
• Move individual pages between notebooks to reorganize content more flexibly.
• Import PDFs directly into selected folders in Paper.
• Move, rename, lock, copy, share, or delete notebooks as needed.

These tools make it easier to manage both short notes and larger projects without having to recreate or manually reorganize your content.

Daily helps you bring your schedule, tasks, and daily work together in one place. With Daily, you can:

• Turn handwriting into To-Dos: Convert handwritten content into actionable tasks and manage them in your To-Do list.
• Organize your schedule: Sync supported calendars, including Google Calendar and Outlook Calendar, to view events alongside your daily plans.
• Manage your daily tasks: View and organize To-Dos by week or month and filter tasks by status.

With Viwoods Cloud enabled, Daily can also sync automatically on AiPaper series. And there's more to explore—Daily also offers a clear overview of your work and quick access to important documents, helping you stay organized and focused throughout the day.

Meeting helps you capture, organize, and review important information throughout your discussions. You can:

• Take handwritten notes while recording: Capture ideas, decisions, and key points naturally during the meeting.
• Use and switch between meeting templates: Import your own templates or choose different meeting formats to structure your notes based on different types of discussions.
• Convert recorded audio into text: Turn meeting recordings into searchable text for easier review.
• Use AI tools to process meeting content: Summarize transcripts, extract key information, and organize important meeting details.
• Turn meeting notes into actionable tasks: Convert important handwritten content into To-Dos and continue managing follow-up tasks in Daily.
• Export your meeting content: Export transcribed content in supported formats such as TXT or PDF.
• Review everything together: Revisit your handwritten notes, recordings, transcripts, and processed content after the meeting.

From capturing ideas during a live discussion to organizing follow-up actions, Meeting works seamlessly with Daily to help you turn meeting outcomes into clear tasks and keep your work moving forward—all within the AiPaper ecosystem.

The main differences are the display and front-lighting system: AiPaper Reader: Features a black-and-white display with 300 PPI and a cool front light, providing sharper text and a whiter-looking screen for reading. AiPaper Reader C: Features a color display with adjustable warm and cool front lighting. You can switch between Color Mode and Black-and-White Mode depending on your reading needs. It offers 300 PPI in Black-and-White Mode and 150 PPI in Color Mode. Both devices do not include or support a stylus, so handwriting and handwritten note-taking are not supported.

Yes, the AiPaper Reader series supports a physical SIM card and 4G mobile data. After inserting and activating a compatible SIM card, you can use mobile data for online reading, AI queries, cloud access, web browsing, and supported Android apps. With a SIM card installed, you can also connect Bluetooth headphones to make and receive phone calls or use voice calling features. Alternatively, you can connect the Reader to a phone hotspot for internet access.

The AiPaper Reader series support ebooks, long-form articles, web content, PDFs, and documents through compatible Android apps. Supported file formats include:

• Documents: PDF, EPUB, EPUB3, MOBI, and AZW3
• Images: PNG, JPG, BMP, and TIFF

You can also install compatible Android reading apps through the Viwoods App Market or Google Play. Third-party app availability and compatibility may vary.
