Starting February 1, WhatsApp will require iOS 15.1 or later on iPhone and Android 5.0 (Lollipop) or later on Android devices. Phones that run older operating systems will no longer be able to log in or send messages, prompting users to update their OS or switch to a newer device to keep using the service.
What the Compatibility Change Means
WhatsApp’s new policy removes support for devices that cannot run the specified operating system versions. Users attempting to open the app on an unsupported phone will see an error message and be directed to the app store for an update or a device upgrade.
Affected iPhone Models
Any iPhone that cannot upgrade to iOS 15.1 will lose access. This includes older models such as iPhone 6, iPhone 6 S, the first‑generation iPhone SE, and earlier devices.
Affected Android Devices
Android phones running versions prior to Android 5.0 (Lollipop) are also excluded. The rule impacts many mid‑range and low‑end smartphones released before 2015.
Why WhatsApp Is Raising the Minimum OS
Requiring newer operating systems lets WhatsApp take advantage of improved memory management, modern network protocols, and advanced hardware capabilities. It also streamlines security updates and enables the rollout of new features such as integrated payments and expanded business APIs.
Impact on Users
Users with older phones may face immediate disruption, especially in regions where device replacement is less frequent. The loss of WhatsApp can affect personal communication, small‑business operations, community groups, and customer‑service channels that rely heavily on the platform.
Steps to Take If Your Device Is Affected
- Check your OS version: Go to Settings and verify whether you are on iOS 15.1 or Android 5.0 and above.
- Update the system: If an official update is available, install it to meet the minimum requirement.
- Consider a new device: When updates are unavailable, choose a phone that supports the required OS version. Many manufacturers offer affordable mid‑range models.
- Back up your chats: Save your conversation history to iCloud (iPhone) or Google Drive (Android) before switching devices.
Looking Ahead
By aligning with newer operating systems, WhatsApp aims to maintain data security, service stability, and the ability to introduce future innovations. Balancing technical progress with accessibility will remain a challenge, particularly in emerging markets where hardware upgrades occur less often. Users should evaluate their options now to stay connected when the February deadline arrives.
