Currently, WhatsApp supports any version of Android from 2.3 or higher, but the company has announced that the app will not support Android 2.3.7 and older versions of Gingerbread after February 1, 2020. This Android version has been existent since 2010, and accounts for 0.3 percent of Android users as per distribution numbers. Additionally iOS 7 and lower versions of Apple’s operating system will also no longer be supported after February 1st 2020. This will come after the end of support for Nokia S40 on December 31st, 2018, as we informed you earlier. You won’t be able to use WhatsApp on the following platforms:
Nokia Symbian S60 after June 30, 2017 BlackBerry OS and BlackBerry 10 after December 31, 2017 Windows Phone 8.0 and older after December 31, 2017 Nokia S40 after December 31, 2018 Android versions 2.3.7 and older after February 1, 2020 iPhone iOS 7 and older after February 1, 2020
Note that some of the listed platforms are no longer actively supported and thus it’s very possible for you to lose access to some features in the app before the end date comes.
