I'm having trouble downloading or updating WhatsApp from Google Play.
As a chat program, WhatsApp has a mature content rating. If you have configured your content filtering, you will need to set it to at least High maturity.
If you are seeing errors when downloading or updating the app (403, 427, 495, 919, 927, "Insufficient space", "Not enough space", etc.) please check the Google Play Help Center for troubleshooting steps.
If you see a "Not available in your country" error or if the Google Play Help Center troubleshooting tips did not help, you will have to download and update WhatsApp from our website. You will have to turn on Unknown sources inside Security in your phone settings. We recommend that you turn this back off once you have downloaded and updated WhatsApp from our website.
