If you have a too old mobile you will have to change it before 2020. The messaging application will stop working on mobiles with Android 2.3.7 and earlier versions on 1 February 2020. WhatsApp will stop supporting these versions of Android and users will not be able to use the updates.
According to previous information given by the company, it was explained that WhatsApp would stop working at the end of 2016 on Android 2.1 and Android 2.2 devices, although this did not finally happen and was delayed until June 30, 2017, at the end of this month. Now Android 2.3 will not be saved either, which will no longer have support in 2020, if the deadlines are met.
If you have a phone with Android 2.3 you should not worry whyand there are still more than two years for WhatsApp stop receiving support and the logical thing would be that in that period of time your phone stops working or you bet on a more modern one during this time.
There are very few phones in the world that work with one of these versions of Android. According to the latest data given by Google on the distribution of versions, only 0.8% of the total number of Android phones has versions 2.3.3 or 2.3.7 installed on your phone.
WhatsApp on other operating systems
Apart from this, WhatsApp also mentions other platforms and when it will stop supporting them. For example, on Nokia Symbian S60 will end on June 20, 2017, in BlackBerry OS and BlackBerry 10 on December 31 of this same year. They will also run out of updates to the Windows operating system. On December 31, 2017, support for Windows Phone 8.0 and earlier versions will end.
