Attention! Guys, maybe your old Android phones will not support many websites in 2021

Provided you got the old Android phones, it is time to really consider an upgrade for you, bro.

According to the news, a lot of webs will no longer work on devices with Android versions before 7.1.1 Nougat.

An organization has already announced that its partnership with certification authority IdenTrust will end on Sept. 1, 2021. With no plans to renew, Let’s Encrypt is planning to completely switch over to its own root certificate and stop default cross-signaling for IdenTrust’s on January 11.

This means that many secure websites will no longer be compatible with older versions of Android.

It could end being a problem. As Let’s Encrypt notes, 33.8 percent of Android devices are running these older versions of the operating system. Those devices will experience certificate errors when trying to visit many secure websites starting in 2021.

Thus, if you were thinking of updating your old Android device, now might be a good time before it becomes obsolete.

Whereas, provided you don’t expect to upgrade your phone, you may still have options. Let’s Encrypt has recommended that old Android device owners download Firefox and use it for their web browsing needs.

“For an Android phone’s built-in browser, the list of trusted root certificates comes from the operating system – which is out of date on these older phones,” explains a post on the organization’s website. “However, Firefox is currently unique among browsers – it ships with its own list of trusted root certificates. So anyone who installs the latest Firefox version gets the benefit of an up-to-date list of trusted certificate authorities, even if their operating system is out of date.”

There is a fair warning: That could solve the mobile browsing issues for now, but you may still experience certificate errors when using apps on your old Android device.
