WhatsApp changes its requirements: Which phones will stop working after the update?

WhatsApp is changing its technical requirements, and some phones that have been in users’ hands for more than a decade will lose access to the messaging app.

The company says the infrastructure update aims to strengthen security and privacy. As a result, devices running older operating systems will no longer receive technical support, security patches or stability updates.

According to WhatsApp’s official support information, the deadlines differ by platform. Starting Sept. 8, 2026, the app will stop working on devices with versions older than Android 6. On iPhones, compatibility will be limited to iOS 15.5 or later from Nov. 30, 2026.

WhatsApp says it periodically reviews which devices and software versions have the fewest active users, allowing it to direct resources toward newer technologies. Its published minimum requirements list Android 5.0 or later, iOS 12.0 or later, and KaiOS 2.5.0 or later, including the JioPhone and JioPhone 2. The article says the affected devices include older Apple models such as the iPhone 3G, 3GS, 4, 4S, 5 and 5c, along with Samsung Galaxy S2, Galaxy S3 mini, Galaxy Trend Lite, Galaxy Core and Galaxy Ace 2 phones. LG Optimus models including the L3 II, L5 II, F5 and L7 II are also listed.
