How can I upgrade my Android OS if my product is unable to find an update?
SYMPTOMS
Updates to the Android operating system are now provided directly from Google instead of coming from Acer. If you attempt to check for software updates on our older tablets, you may get the message "Update service temporarily unavailable".

- Visit the Drivers and Manuals section of the Acer support website.
- Enter your Serial Number/SNID or search for your product by Model.
- Select the OS tab, and then click on the most recent firmware version.
- Click the Download link for the file you want to download.
- Use a computer to format your microSD card (512 MB is recommended).
