Smartphones running Android 5.0 and Android 5.1 lost official support for WhatsApp on September 8, 2026, under updated technical standards enforced by Meta. The company now mandates Android 6.0 (Marshmallow) or newer as the minimum threshold for both the standard WhatsApp Messenger and the corporate WhatsApp Business application. In addition to the cutoff for older Google systems, the platform has scheduled a requirement increase for Apple iPhone users that takes effect on November 30, 2026.
Meta revises its compatibility thresholds every year by evaluating the active hardware base connected to its servers. The goal of this annual review is to retire legacy operating systems that hold the smallest share of active users and lack the security architecture needed to run current messaging features.
“We stop supporting older devices and operating systems on an ongoing basis. Retiring older operating systems lets us support newer ones and keep up with the latest advances in technology and security,” the WhatsApp Help Center, managed by Meta, stated in its official documentation.
Apple iPhones face November deadline for iOS 15.5 transition and login checks
Following the September restriction placed on Google operating systems, WhatsApp’s compatibility schedule turns to hardware manufactured by Apple. The messaging service currently operates on iPhones running iOS 15.1 or later, but that baseline will rise to iOS 15.5 and newer versions starting November 30, 2026. Despite the higher software threshold, no specific iPhone model will be permanently locked out due to hardware limitations on that date, because every Apple handset capable of running iOS 15.1 can also install the free upgrade to iOS 15.5.
In October 2026, the platform also began deploying a server-side operating system check across both Android and iOS accounts. When the system detects outdated software, it triggers an unskippable full-screen prompt that blocks the user from logging in until the phone’s operating system is updated through the device settings. Because this verification happens directly on WhatsApp’s servers, simply installing a newer version of the app does not bypass the restriction, protecting accounts against malware that targets unpatched system vulnerabilities before messages are encrypted.
Meeting the minimum software version is not the only technical rule required to register and maintain an active profile on the platform. A handset must be able to receive SMS text messages or voice calls during the security verification process, which prevents users from setting up new accounts on devices that connect exclusively through Wi-Fi networks. Furthermore, on Apple devices, the company advises against using jailbroken or unlocked phones, noting that it does not support modified versions of the iPhone operating system.
Legacy Android Lollipop smartphones lose access without Android 6.0 upgrade
Meta and WhatsApp do not publish an official model-by-model list of blocked smartphones during their annual reviews, choosing instead to establish a strict software version floor. In practical terms, a handset originally released with Android 5.0 or 5.1 (known as Lollipop) only loses permanent access to the messenger if its software remains frozen on those builds without an official manufacturer update path to Android 6.0 or higher.
Numerous smartphones launched around 2014 and 2015 shipped with Android 5 from the factory or reached the end of their manufacturer update cycles on that generation. Unless they have been upgraded to Android 6.0, 16 widely used models commonly linked to this transition — alongside several other older lines capped at the same technical limit — can no longer run the application:
- Samsung: Galaxy S6, Galaxy S6 Edge, Galaxy Note 4, Galaxy A3 (2015), Galaxy A5 (2015), Galaxy J5 (2015), Galaxy J7 (2015), Galaxy S4, Galaxy Note 3, Galaxy S5 Mini, and Galaxy Grand Prime.
- Motorola: Moto G (1st and 2nd generation), Moto E (1st and 2nd generation), and Moto X (1st generation).
- LG: LG G3, LG G4, LG G Flex 2, LG G2, G2 Mini, G3 Stylus, L Prime, and L Fino.
- Sony: Xperia Z3, Xperia Z3 Compact, Xperia Z, Z1, E3, M2, and T3.
- HTC: One M8 and Desire 820.
- Google: Nexus 4, Nexus 7 (2012), and Nexus 10.
Steps to verify installed software and back up chat history
Before cutting off access on an aging operating system, the application sends direct on-screen alerts to affected users so they can update their software or replace their hardware. “Before we stop supporting your operating system, you’ll be notified in WhatsApp. We’ll remind you a few times to upgrade,” the WhatsApp Help Center explained.
To prevent losing media files and message histories when moving to a phone that supports Android 6.0 or iOS 15.5, users should back up their data to Google Drive or local device storage through the app’s chat settings menu before switching handsets. Android owners who are unsure which software build is running on their phone can verify the information by opening the device’s Settings menu, tapping the About phone or About device section, and checking the number listed under Android version. Meanwhile, iPhone owners can install available upgrades by opening Settings, selecting General, and tapping Software Update to download the latest compatible release.
