Starting next year, WhatsApp refuses all smartphones with Windows Phone – up to the latest 8.1 Update 2. These are almost all smartphones until the 2014 release. These are mainly Lumia smartphones, which were manufactured by Nokia in partnership with Microsoft
Popular smartphones on Windows Phone that will lose WhatsApp are Lumia 520, 525, 620, 625, 630, 720, 820, 920, 925, 1020, 1320. For some smartphones from this list, it is possible to install a test or unofficial build of Windows 10 Mobile, but often these firmwares are unstable.
But WhatsApp will continue to work on all smartphones that have upgraded to Windows 10 Mobile or worked on it initially. But Microsoft itself has already closed support for this operating system, so the messenger on these smartphones will last at best a couple more years.
With iPhones, everything is simpler. WhatsApp prohibits iPhone 4 and older models. That is, all Apple smartphones that came out before 2011.iPhone 4S, for example, received an update to iOS 9, so WhatsApp will still work on it. As with all newer Apple smartphones.
From February next year, WhatsApp will no longer support all smartphones on Android 2.3.7 and older. Dozens of models that came out approximately between 2009-2011 fall under the ban. Now Android 2.3 and its variations occupy a share of 0.3% of all active smartphones on Android – taking into account the total number of devices, it is about 7.5 million smartphones worldwide.
For example, WhatsApp will stop working on the first Samsung Galaxy S, Galaxy Mini, Galaxy Gio, Google Nexus One, Sony Ericsson Xperia X10, Sony Ericsson Xperia Play, LG Optimus One, HTC Wildfire S, HTC Desire, HTC Desire HD, HTC Desire Z and many other smartphones that have not updated to Android 4.0 Ice Cream Sandwich.
The only way to extend the life of WhatsApp on an old smartphone is to install unofficial firmware Android 4.0 or newer. The main thing is to catch it before February 2020.
