Smartphones with Android 7.1 and below will lose access to HTTPS sites

Let’s Encrypt has warned that smartphones running Android below version 7.1.1 will no longer support its issued root certificates starting in 2021.

Let’s Encrypt will stop cross-signing these certificates by default on January 11, 2021 and will end the partnership in this direction on September 1 of the same year.

A partial solution might be to install the Firefox browser (Mozilla is a Let’s Encrypt partner) and use its certificate store, but this will not work with other clients.

It should be noted that the termination of support for outdated versions of the search engine is a common practice among developers. However, this can lead to a number of problems. In particular, the loss of access to a number of sites.

Let’s Encrypt estimates that about 33.8% of Android users on Google Play are running OS versions earlier than 7.1.1.
