Change takes effect on September 8, 2026, and affects old Android devices that cannot reach Android 6 or higher versions
WhatsApp will stop working on some old Android phones starting from September 8, 2026, when the app will require Android 6 or higher to continue operating. The change mainly affects devices still running Android 5.0 or Android 5.1, versions released over a decade ago.
The rule appears in WhatsApp’s own Help Center, which states that from this date, only devices with Android 6 and newer versions will be compatible with the messenger. For iPhones, the requirement remains iOS 15.1 or later, with no new change announced for this specific update.
In practice, the cutoff does not depend solely on the brand or model of the phone. The main point is the operating system version installed on the device, as some older models may have received updates, while others remain stuck on obsolete Android versions.

Phones with Android 5 no longer meet WhatsApp’s minimum requirements
The change is part of WhatsApp’s periodic compatibility reviews. Large apps, such as messengers, banks, and social networks, often abandon old system versions when they no longer offer the same level of security, performance, and technical support.
The impact is expected to be greater on older smartphones from brands like Samsung, Motorola, LG, Sony, Huawei, and HTC, especially models released between 2012 and 2015 that have not received recent updates. However, the company has not published a definitive official list of affected devices, making checking the Android version the safest route.
Among the models frequently mentioned in surveys about old devices are lines like Galaxy S4, Galaxy S5, Moto G from the first generations, LG G2, LG G3, Sony Xperia Z, and some old HTC and Huawei models. These names serve as a warning but do not replace direct verification in the device’s settings.
Why WhatsApp stops working on old phones
The main reason lies in the combination of digital security and new app functions. Old systems stop receiving important fixes from manufacturers, increasing the risk of failures, incompatibilities, and limitations for more modern features.
WhatsApp also needs to maintain stable operation of calls, media sending, encryption, notifications, and new tools. When a system becomes too outdated, the technical cost of maintaining compatibility increases and can compromise the app’s evolution for most users.
This does not mean that all old phones will stop on the same day due to the device’s age. An old phone that still runs Android 6 or higher can continue functioning, while another, even more recent in appearance, may lose access if it is stuck on Android 5.
How to know if your phone will be affected
The user should open the phone’s settings and look for the About phone, Software information, or System area. The name may vary depending on the brand, but the information sought is the Android version.
If it shows Android 6, Android 7, Android 8, or higher versions, the device remains within the minimum requirement informed for September 2026. If it shows Android 5.0 or Android 5.1, the phone is in the risk group and may lose access to WhatsApp on the scheduled date.
It is also important to check if there is a pending update. On some devices, an official update can bring the system to a compatible version, but many old models no longer receive software packages from manufacturers.
What to do before the deadline
Those using an old phone should backup conversations before any device change. On Android, this backup can be done through WhatsApp itself, usually using the Google account linked to the phone.
It is also worth reviewing important photos, videos, documents, and audios. Many users only notice the lack of backup when they switch devices and discover that old conversations were not saved correctly.
If the device does not accept an update to Android 6 or higher, the solution will be to migrate to a compatible phone. For those who rely on the app for work, family groups, school, commerce, or customer service, leaving this check to the last minute can cause disruptions.
WhatsApp Business may also be affected
The rule is especially important for small businesses that still use old cell phones for customer service. Those who work with WhatsApp Business should treat the update as a preventive measure, as losing access to the app can affect sales, orders, deliveries, and contact with consumers.
The ideal is to check the device used by the company in advance. If the cell phone is on Android 5, a replacement or update needs to be planned before September 2026 to avoid service interruptions.
The change also reinforces a common discussion in Brazil. Many users keep cell phones working for several years, either to save money or because the device still meets basic needs. The problem is that, even if it works for calls, photos, and simple browsing, an old system may fail to keep up with essential applications.
Change reignites debate over smartphone lifespan
The end of WhatsApp support for older versions of Android shows how the real lifespan of a smartphone depends less on its physical appearance and more on software support. A device may be in good condition, but if it doesn’t receive updates, it ends up losing access to important services.
This situation mainly affects those who use entry-level cell phones or old models inherited from family members. For many Brazilians, changing devices is not a simple decision, as the price of smartphones weighs on the budget.
The controversy lies precisely on this point. On one hand, companies advocate for more modern requirements to maintain security and performance. On the other, users see still-functional cell phones become limited by compatibility decisions that end up pushing for a replacement sooner than desired.
And you, do you think it’s fair for WhatsApp to end support for old cell phones in the name of security, or does this force many people to change their devices prematurely? Leave your opinion in the comments and tell us if you still use an old cell phone in your daily life.
