Security News > 2020 > November > Let’s Encrypt Warns Some Android Users of Compatibility Issues
Let's Encrypt has warned users whose devices are running older versions of Android that they may start getting errors next year when visiting websites secured by its certificates.
The organization estimates that roughly one-third of Android devices are still running these older versions, which means their users will start getting certificate errors once the cross-signed certificate expires.
While the situation might improve until next year when the certificate expires, Let's Encrypt believes there will still be many impacted devices so it's trying to raise awareness.
Let's Encrypt has advised users who cannot upgrade their Android devices to install Firefox on their smartphone, as Firefox comes with its own list of trusted root certificates rather than using the list from the operating system.
The organization has also provided recommendations for website owners and users who get certificates from their hosting provider.
