Older Android phones will get errors on some websites

Up to a third of existing Android smartphones will start receiving error messages from sites protected by Let's Encrypt.

It may not be cool and it certainly is not up to date, but there are millions of old Android smartphones out there running Android 7.1 Nougat of 2016 or earlier version. On September 1, 2021, however, these phones will begin to fail when trying to connect to sites protected by Let's Encrypt Secure-Socket Layer (SSL) / Transport Layer Security (TLS) certificates.


Let's Encrypt is the hugely popular, open source certification authority (CA). Thanks to his service, more than one billion websites have been "insured". Works well, but the original Let's Encrypt root certificate, which was based on cross-signature by IdenTrust, "DST Root X3", will expire on September 1, 2021.

With most operating systems, this would not be a problem. Let's Encrypt now has its own root certificate, ISRG Root X1 and most operating systems and browsers can work with it. Unfortunately, this is not the case with Android.

It's not new that Android is not updated often enough by vendors. Any Android phone with Android 6 or earlier has not received security updates since last year. But users like the tens of millions who are still running Windows 7, do not pay much attention to safety until they actually face a problem.

This coming problem, however, is a problem they will not be able to ignore. At best, if you continue to use one of these older phones, you will receive a message error that will ask you if you want to go to the site. In the worst case, you will not be able to access your favorite site at all.

So what can be done about it? Well, do not look in Let's Encrypt for an easy solution. You see, that's not really his problem. From day one, Android hardware vendors refused to update systems their. If you want an Android smartphone that keeps up with the state of the operating system, your only option is to buy a phone Google Pixel or one Samsung.

Of course not everyone can afford to buy a new phone, so you can install Firefox Mobile. Currently supports Android 5.0. It helps because o Firefox is the only program web browsing, which comes with its own list of trusted root certificates.
