==Mandatory updates== | ===Mandatory updates=== | ||
WhatsApp | WhatsApp requires users to use updated versions of the app by first giving them an in-app warning if they have not updated for a while. If the user still chooses not to update, usage of the app will be disabled entirely.{{Citation needed|reason=How long before this happens? Any screenshots?}} This can pose problems in certain cases, such as being in an area with poor or limited internet connectivity or using an older device that is no longer supported.<ref>{{Cite web |last=Coyle |first=Dylan R. |title=WhatsApp drops support for Android KitKat |url=https://www.androidpolice.com/whatsapp-support-android-kitkat/ |website=Android Police |date=24 Oct 2023 |access-date=17 Feb 2026 |url-status=live |archive-url=https://web.archive.org/web/20231025193121/https://www.androidpolice.com/whatsapp-support-android-kitkat/ |archive-date=25 Oct 2023}}</ref><ref>{{Cite web |author=Ro |title=WhatsApp to drop support for older Android devices on January 1, 2025 |url=https://www.gsmarena.com/whatsapp_to_drop_support_for_older_android_devices_on_january_1_2025-news-65834.php |website=GSMArena |date=22 Dec 2024 |access-date=17 Feb 2026 |url-status=live |archive-url=http://web.archive.org/web/20260217143250/https://www.gsmarena.com/whatsapp_to_drop_support_for_older_android_devices_on_january_1_2025-news-65834.php |archive-date=17 Feb 2026}}</ref> <!-- In my experience, WhatsApp is one of the few apps to function near-perfectly on 3G, even rural areas.

===Message deletion and editing (''2017—'')=== | |||
Since late 2017, WhatsApp allows message senders delete messages for a limited duration after sending.<ref>{{Cite web |author=Himanshu |title=WhatsApp gets ability to delete messages |url=https://www.gsmarena.com/whatsapp_gets_ability_to_delete_messages-news-27955.php |website=GMSArena |date=27 Oct 2017 |access-date=17 Feb 2026 |url-status=live |archive-url=https://web.archive.org/web/20180318124926/https://www.gsmarena.com/whatsapp_gets_ability_to_delete_messages-news-27955.php |archive-date=18 Mar 2018}}</ref> This time limit was extended, to slightly over an hour in 2018<ref>{{Cite web |author=Ricky |title=WhatsApp time limit for deleting messages increases to over an hour |url=https://www.gsmarena.com/whatsapp_time_limit_for_deleting_messages_increases_to_over_an_hour-news-30053.php |website=GSMArena |date=12 Mar 2018 |access-date=17 Feb 2026 |url-status=live |archive-url=https://web.archive.org/web/20180313043109/https://www.gsmarena.com/whatsapp_time_limit_for_deleting_messages_increases_to_over_an_hour-news-30053.php |archive-date=13 Mar 2018}}</ref> and two and a half days in 2022.<ref>{{Cite web |last=Mehta |first=Ivan |title=WhatsApp extends time limit to delete a message to 60 hours |url=https://techcrunch.com/2022/08/09/whatsapp-extends-time-limit-to-delete-a-message-to-60-hours/ |website=TechCrunch |date=9 Aug 2022 |access-date=17 Feb 2026 |url-status=live |archive-url=http://web.archive.org/web/20240225131536/https://techcrunch.com/2022/08/09/whatsapp-extends-time-limit-to-delete-a-message-to-60-hours/ |archive-date=25 Feb 2024}}</ref> While there is a message noting that "This message was deleted," it is not possible to see what was contained in the message. | |||
Additionally, since 2023, WhatsApp lets message senders edit messages for up to fifteen minutes after sending. When a message is edited by the sender, while it is noted the message has been edited, the recipient can no longer see the original message.<ref>{{Cite web |last=Schroeder |first=Stan |title=WhatsApp finally lets you edit messages, but you have to be fast |url=https://mashable.com/article/whatsapp-edit-messages-feature |website=Mashable |date=23 May 2023 |access-date=17 Feb 2026 |url-status=live |archive-url=https://web.archive.org/web/20230523172541/https://mashable.com/article/whatsapp-edit-messages-feature |archive-date=23 May 2023}}</ref> | |||
In effect, this WhatsApp feature allows the sender to remotely delete or edit existing information on the recipient's device without the consent of the recipient. | |||
<!-- Could this be expanded to explain why this is an incident? | |||
Technically senders are also updating existing information on the recipients device by sending them the original message. | |||
This is a feature included in several other messenger apps (e.g. discord, element). There are examples of users requesting it when it doesn't exist (example on steam https://steamcommunity.com/groups/SteamClientBeta/discussions/3/1694924244564842077/). | |||
In my experience it's mostly used to fix typos and spelling errors - if anything it helps protects the sender's right to privacy. --><!-- In response to the first comment: I edited this section to make the tone more neutral, but I also question the reasoning behind this being included as an incident. Especially since Telegram is a recommended alternative and has a similar feature. --> | |||

WhatsApp | WhatsApp also introduced "view-once" messages in 2021 and disabled screen captures of them in 2022. "View-once" messages are deleted after being viewed.<ref name="TechCrunch-20220809" /> | ||
===Disabling screen captures of profile pictures (''2024—'')=== | |||
In March 2024, WhatsApp started disabling screen captures of profile pictures viewed in full screen to "protect the privacy" of its users. This made possible because mainstream mobile operating systems, [[Android]] and [[iOS]], let applications disable screen capturing on devices without the consent of device owners.<ref>{{Cite web |author= |title=About profile photo screenshot blocking |url=https://faq.whatsapp.com/1799783917198636 |website=WhatsApp |date= |access-date=17 Feb 2026 |url-status=live |archive-url=http://web.archive.org/web/20251109165725/https://faq.whatsapp.com/1799783917198636 |archive-date=9 Nov 2025}}</ref> | |||
