This change is most likely to affect Android devices that cannot upgrade to at least Android version 5, including early Kindle Fires, early Samsung Galaxy tablets, and Kobo Arc devices (all of which were released in 2014 or earlier). Based on our analytics, usage of these devices has been declining and currently accounts for approximately 0.5-1% of users across all OverDrive libraries. Most devices that don't support TLS 1.2 are also no longer supported by their manufacturers, cannot access other modern apps and websites, and currently offer a substandard experience with many apps and websites, including your OverDrive service.
To keep using the OverDrive app and OverDrive websites, affected patrons will need to either update their device's operating system (if possible) to a version that supports TLS 1.2 or switch to a device that supports TLS 1.2. Users can also choose to only update their device's browser to a version that supports TLS 1.2, which will allow them to use OverDrive websites in their browser (though they won't be able to use the OverDrive app). Users of early Kindle Fires and other ereaders that don't support TLS 1.2 will still be able to read library ebooks that are delivered or transferred to their Kindle Fire or ereader from a supported device.
Current Libby users on Android devices should not be affected, as Libby’s minimum system requirements were already raised to Android 5 in June 2020.
