WhatsApp’s new ‘block’ rule for older smartphones: Find out if your phone is safe

WhatsApp is testing a new rule that may require users with older Android phones and iPhones to update their software. Here is what you need to know about this new login block.

WhatsApp is testing a new login rule for certain Android and iPhone users. Under this measure, users on devices running older Android or iOS versions may be prompted to update their phone’s software before they can use WhatsApp.

This change has currently been observed among a limited number of users. According to a report by WABetaInfo, WhatsApp is displaying a screen to some users asking them to update their device software. The screen also provides information on checking the phone’s current operating system version.

Will WhatsApp fail to open without an update?

Users who see this new prompt cannot simply dismiss it and continue using WhatsApp; they must install the latest operating system update available for their device.

This change is being implemented via a server-side update rather than a standard app update. This means the company can enforce this requirement for specific accounts directly from its servers without requiring a separate app update.

Which Android phones and iPhones will face the login block?

WhatsApp has not yet clarified exactly which Android or iOS versions will fall under the scope of this requirement.

It is also unclear whether this rule will apply to all older operating systems or only to those versions that no longer receive security updates.

Older operating systems can pose security risks due to the lack of new security patches. Since WhatsApp handles sensitive data—such as personal messages, calls, and account information—keeping device software updated is crucial for security.

What does this mean for users with older phones?

If an older phone does not support the installation of the latest Android or iOS version, using WhatsApp in the future could become difficult. In such cases, users might have to purchase a new device if WhatsApp discontinues support for the older operating system version.

However, WhatsApp has not yet specified which devices will be permanently affected by this change.

Focus on Unofficial WhatsApp Web Clients

WhatsApp is also reportedly testing a new warning feature regarding unofficial WhatsApp Web clients.

This warning could appear in the ‘Linked Devices’ section of WhatsApp, prompting users to switch back to the official WhatsApp client.

Third-party clients are software applications that can connect to a WhatsApp account but have not been developed or officially supported by WhatsApp or Meta.

WhatsApp has not officially confirmed this warning feature, nor has it provided a timeline for a wider rollout.

Work on Additional Security Features

WhatsApp is also working on other features related to account security and privacy, including scam alerts and restricted chats.

For now, the login requirement linked to OS updates appears to be limited to a select group of Android and iOS users. If you do not see this warning on your phone, WhatsApp should continue to function as usual.

WhatsApp has not yet disclosed the specific Android and iOS versions that might be subject to this login block. It is also unclear how many more users will be included in the current test.
