At the end of February 2026, WhatsApp will stop working on older phones.This will force many users to check if their phone is still compatible or if it's time to upgrade to a newer model. The measure will particularly affect those still using smartphones that are several years old, both Android and iPhone.
The change is part of the regular policy of the app's owner, Meta, which periodically It reduces support for outdated operating systems to improve security, performance, and compatibility.In practice, this means that thousands of devices that cannot be updated to newer versions of the system will be left without access to the world's most popular messaging app.
When will WhatsApp stop working and on which phones?
The disconnection will occur between the last week of February and March 1, 2026, date from which many of these terminals will begin to show errors, difficulties in sending or receiving messages and, finally, the total impossibility of opening the application.
In the case of AndroidThe requirement will be to have at least Android Lollipop 5.0 or a higher version. Any phone that falls below that version. will gradually lose access to WhatsAppThis includes devices with Android 4.4 KitKat, 4.3, 4.2, 4.1 (Jelly Bean) and all previous versions, many of them more than a decade old.
To iPhonethe minimum requirement will become iOS 15.1Models that cannot reach that operating system version will be excluded. The direct consequence is that iPhone 6, iPhone 6 Plus, and all previous models will lose access to WhatsAppsince they have no possibility of updating to that version of iOS.
Meta has explained that this is a global decision, so it also affects users of Spain and the rest of EuropeThe deadline will be the same in all markets, although notifications and alerts within the app may appear a few days apart depending on the country and device.
Android and iOS versions that will no longer be supported
On Android phones, the application will stop working on all smartphones that cannot be updated to Android version 5.0 or higher. In other words, Phones that still use Android 4.4 KitKat, Jelly Bean (4.1, 4.2, 4.3) or even older versions They will be completely taken out of service.
These systems have gone years without receiving security patches or improvements from manufacturers, making the terminals an easier target for attacks and malfunctions. The lack of official maintenance makes it very difficult to integrate the latest security and encryption features required by WhatsApp..
In the Apple ecosystem, the path is similar: the app will only remain compatible with iPhones with at least iOS 15.1As a result, models still very present in many homes, such as the iPhone 6 and iPhone 6 PlusThey will be banned because their maximum update falls below the required version.
Other older models, such as iPhone 5s, iPhone 5c or iPhone 5They had already been out of Apple's major update cycle for some time, and with this decision, They will also have their access to the messaging application blocked.Although some of these devices are still used as a second mobile phone, for children or the elderly, they will no longer be able to use WhatsApp officially.
The platform itself emphasizes that this type of compatibility reduction is a periodic process: Each year, a review is conducted to determine which operating systems have fewer users and have stopped receiving support from the manufacturer. to decide which versions are removed from the official list.
Specific mobile phone models that will lose WhatsApp
Although the company focuses on operating systems, a good number of specific phones have already been identified. They will no longer be compatible with WhatsApp from the end of February 2026Many of them were bestsellers in their time and are still active in the hands of users who have not made the leap to newer models.
Among the mobiles Android The most affected devices are those from very popular brands in Spain and Europe, such as Samsung, LG, Sony, Motorola, and Huawei. Some notable examples are:
- Samsung Galaxy S3
- Samsung Galaxy S4 y Samsung Galaxy mini S4
- Samsung Galaxy Ace 4, Core, Trend and J2
- Sony Xperia M
- Sony Xperia Z2 and Z3
- LG Optimus L7 IIas well as others from the Optimus L3, L5, L7 and F5 family, including some variants Dual
- Motorola Moto E (first generation) and some Motorola Moto G initials
- Huawei Ascend Mate, along with models like the G740 and D2
- HTC Desire 500 and other contemporary devices that do not reach Android 5.0
In the case of Apple The compatibility cuts will primarily affect entry-level models and older iPhones. Among the models that they will no longer be able to use WhatsApp are:
- iPhone 6
- 6 iPhone Plus
- iPhone 5s
- iPhone 5c
- iPhone 5 and earlier
In all these cases, the problem is the same: There is no official way to update to iOS 15.1Therefore, although the application may still work today, it will gradually stop working from the specified date.
The list of specific models is not exhaustive. Other phones with similar features that also fail to update in time could join this group.especially in the Android segment, where there is a huge variety of manufacturers and customization layers.
Reasons: security, performance, and new features
Meta justifies this move on several fronts. On the one hand, Older operating systems no longer offer the security standards that the company considers necessary to protect users' data and encrypted communications.
With each update, WhatsApp introduces Improvements in encryption, additional privacy controls, and protection mechanisms against fraud and cyberattacksMaintaining compatibility with outdated platforms makes it difficult or impossible to implement these functions correctly and stably.
Furthermore, by focusing on newer versions of Android and iOS, the company can to better optimize application performance and take advantage of the technical capabilities of modern phonessuch as more powerful processors, more memory, and faster network connections.
Another important aspect is the use of internal resources. Supporting a large number of older versions requires more development, testing, and maintenance time.According to the company, this is not worth it when the number of active users on those platforms is already very small.
Ultimately, the reduced compatibility allows the company focus their efforts on the systems where the majority of the community is concentratedMaintaining a balance between innovation and security is common practice across the technology sector, not just in messaging applications.
How WhatsApp will notify and what the user will notice
Users whose devices are about to lose support will not find the change happening overnight without prior notice. WhatsApp will send notifications within the application itself., informing that the mobile phone will soon no longer be compatible.
Those messages will recommend back up your chats and filesas well as checking if the phone can be updated to a new version of the operating system. In some cases, the notification will also clarify that no updates are available and that it will be necessary to change devices.
As the deadline approaches, users will begin to experience various problems: Errors logging in, difficulties sending or receiving messages and multimedia content, or failures to download or update the application from the official store.
Once support ends, the app may stop opening altogether. In other cases, it may be possible to access it for a while, but No new messages will arrive, and calls or video calls can't be made.leaving the service basically unusable.
Furthermore, even if the user manages to keep the app installed, You will no longer receive security patches or updatesThis poses an added risk, especially on mobile phones that already do not receive system updates.
What to do if your mobile phone is among those affected
If you suspect your phone may be on the list of those affected by the 2026 switch, the first thing to do is check the operating system versionOn Android, you can check this in Settings > About device > Android version; on iPhone, in Settings > General > About.
If your mobile phone is running Android 5.0 or iOS 15.1 or lower, you should check if there are any updates available. If the manufacturer still offers a newer version, installing it can keep WhatsApp running for a few more years.provided that the minimum required by the application is met.
If your phone no longer receives new versions, there are two essential steps. The first is back up important conversations and filesOn Android, backups are usually done via Google Drive; on iPhone, via iCloud.
Once the data is saved, the second step is consider upgrading to a compatible smartphoneYou don't need to go for the latest high-end model: many current mid-range models offer update support for several years and more than meet the requirements of WhatsApp and other popular apps.
For those who don't want to part with their old phone, they can always keep it for other offline tasks or basic functions, but They will no longer be able to use WhatsApp securely or with all its features. beyond the marked dates.
Impact in Spain and Europe: users, businesses and families
In markets like Spain and the rest of Europe, where WhatsApp has become an almost indispensable toolThe end of support for older mobile phones will be felt in several areas.
On one hand, it will affect elderly people or users who still use very old smartphones as the primary device. Many of these terminals still work for calls and SMS, but they do not meet the current technical requirements of the messaging app.
On the other hand, it can also have repercussions on small shops, self-employed and local businesses They maintain customer service lines with phones that are several years old, especially on Android. For them, losing the app on that device could mean restructuring part of how they communicate with customers and suppliers.
In families, it will be common to find second-hand or inherited mobile phones Used by teenagers or as emergency phones. From the end of February 2026, many of these devices will no longer be usable for WhatsApp chats, so it's a good idea to check which models you have at home in advance.
Although the measure may be inconvenient for some users, This is part of a general trend in the sector: focus development on more modern systems and leave behind devices that no longer receive support from their own manufacturers.
In practice, all this change means that those who want to continue using WhatsApp smoothly in 2026 will need to Make sure your mobile phone meets the minimum requirements, back up your data, and consider a device upgrade if necessary.The app will continue to evolve with new features and increased security requirements, but older devices will gradually be left behind as support focuses on newer platforms.
