Solution 1Recommended

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.

1
Check for system updates

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.

2
Install the update

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.

3
Access Office for the web

If no update is available and your device remains on Android 8.1.0, open a mobile web browser such as Google Chrome.

4
Sign in to Microsoft 365 online

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.
