WhatsApp Blocks Login on Outdated Android and iOS Until Users Update
The change arrives through a server-side update, so no new WhatsApp version is needed; affected users see a prompt to update their phone's OS.
WhatsApp has introduced a feature that stops users from logging in until they update their phone's operating system, according to gsmarena.com. The change was delivered through a server-side update, meaning it reaches both Android and iOS devices without users needing to install a specific version of the app.
Those affected are shown a screen instructing them to apply a system update through Settings before they can log in again. The same screen tells them how to check which OS version their phone is currently running.
WhatsApp does not offer a way to skip the operating system update. According to the report, the restriction is in place for security reasons.
Why the app checks your OS
The block applies to outdated versions of Android and iOS rather than to the WhatsApp build itself, so installing the latest app release alone will not clear the prompt. Users who see it have to update the phone's software first, then return to the app to sign in.
