From October 1, 2025, WhatsApp will no longer work on several cell phone models with outdated operating systems, such as Android 5.0 or lower and iOS 15.1 or earlier. The measure, announced by Meta, affects popular devices, such as the Samsung Galaxy S5 and iPhone 5, which will no longer receive app updates. The decision aims to ensure security and compatibility with new features. Users of these devices may face difficulties sending messages or even accessing the application.
The company recommends updating the operating system or purchasing a new device to continue using WhatsApp. The change reflects a common practice in applications that seek to optimize performance and protect data. Affected models include devices released between 2012 and 2014, which do not support newer versions of the systems.
- Impacted models: Samsung Galaxy S5, LG G3, iPhone 5, iPhone 5c, among others.
- Solutions: Update the system or change the device.
- Deadline: From October 1, 2025.
Reasons for change
The interruption of support occurs to keep up with technological advances and reinforce security. Old operating systems cannot run the latest versions of WhatsApp, compromising the user experience.
This practice is recurrent in the technology industry, as frequent updates guarantee better performance and protection against vulnerabilities.
Affected devices
Android models include the Samsung Galaxy S5, LG G3, Sony Xperia Z2, Motorola Moto G (1st generation), Huawei Ascend Mate 2 and HTC One M8. In the case of iPhones, the iPhone 5, iPhone 5c and iPhone 6 (no update beyond iOS 12) will be impacted.
The list reflects devices released more than a decade ago that do not support the application’s minimum requirements.
Users of these devices may notice failures when sending messages or accessing WhatsApp.
Meta warns that personal data may be vulnerable without security updates.
Alternatives for users
To continue using WhatsApp, you can check if your device allows updating to a newer version of the operating system. Otherwise, replacement with a compatible model will be necessary.
Changing devices may be the only solution for models that do not support updates.
Risks of outdated versions
Using WhatsApp on older systems increases exposure to security flaws and bugs. Regular updates fix vulnerabilities and ensure new features like group calling and advanced encryption work.
Without support, the application may present instability, such as crashes or errors when sending messages.
Market impact
The decision could boost the sale of new smartphones, especially among users of older devices. Manufacturers like Samsung and Apple offer affordable models compatible with the versions required by WhatsApp.
The end of support also reflects rapid technological evolution, which requires more modern devices to keep up with new features.
Practical recommendations
Check the operating system version in the phone’s settings menu. If your device is on the list of affected models, plan to update or replace it before October 2025.
