Question details
The user is unable to install or run Microsoft Office mobile applications on a Vivo Y81 smartphone due to operating system requirements.

- Product
- Microsoft Office Mobile
- Device & OS
- Vivo Y81 (Android 8.1.0)
- Scenario
- Attempting to install, open, or use Microsoft Word, Excel, and PowerPoint mobile apps on an older Android device.
- Observed behavior
- The Microsoft Office applications fail to install or function because the device's operating system (Android 8.1.0) does not meet the minimum requirement of Android 10.0 or later.
Check your current Android version by navigating to Settings > System Update on your Vivo Y81 to see if a newer operating system version is available for your device.
Update the Operating System or Use Office for the Web
Since modern Microsoft 365 apps require Android 10.0 or newer, you must either update your device's software or use the web-based version of Microsoft Office.
Microsoft frequently updates its mobile apps to require newer versions of Android for security and performance reasons. If your device cannot be updated to Android 10.0, the native apps will not be officially supported.
Open the Settings app on your Vivo Y81, scroll down, and tap on 'System Update' to check if an update to Android 10.0 or later is available.
If an update is available, follow the on-screen instructions to download and install it. Once updated, try downloading Microsoft Office from the Google Play Store again.
If no update is available and your device remains on Android 8.1.0, open a mobile web browser such as Google Chrome.
Navigate to office.com, sign in with your Microsoft account credentials, and use the web-based versions of Word, Excel, and PowerPoint directly in your browser.

Use WPS Office as a Compatible Alternative for Older Android Devices
If your Vivo Y81 cannot be updated to Android 10.0, WPS Office is an excellent, free, and lightweight alternative. It provides seamless performance on older Android versions while maintaining robust compatibility with all Microsoft Office file formats.
- 1. Download from Google Play: Open the Google Play Store on your Vivo Y81, search for 'WPS Office', and tap 'Install'.
- 2. Open and grant permissions: Launch the WPS Office app and grant the necessary storage permissions so it can locate your existing files.
- 3. Edit your documents: Tap on any existing Microsoft Office file on your device to open, edit, and save it directly within WPS Office.
