WhatsApp is preparing to restrict login access for users running outdated operating systems, according to a report from GSMArena. Devices on iOS versions older than 15.1 and Android versions older than 5.0 (Lollipop) will no longer be able to sign in once the change takes effect.

According to WhatsApp's official support documentation, the move is aimed at strengthening security and improving overall app performance. Older operating systems often cannot support newer encryption standards and security patches, making it necessary for the company to phase out compatibility with outdated software. The rollout is expected to happen gradually rather than all at once, giving users some time to update their devices.

This change is particularly relevant for users relying on budget or older smartphones, as many of these devices still run outdated OS versions. WhatsApp remains one of the most widely used communication apps globally, making compatibility issues a significant concern for a large portion of its user base.

Users are advised to check their device settings for available software updates to avoid losing access to WhatsApp. For those using devices that can no longer be updated to meet the minimum requirements, upgrading to a newer smartphone may become necessary to continue using the app without interruption.
