Data Not Linked to You

Currently, WhatsApp's principal platforms, which are fully supported, are devices supporting mobile telephony running Android, and iPhones. Engadget called the revamped feature "WhatsApp’s version of an AIM away message" and likened it to Instagram's and Facebook's Notes. Prior to the update, the feature was "largely hidden within the apps menus" and difficult to find, with the reason for updating being that WhatsApp wanted the feature to be used more often.

• Both Telegram and Signal in particular were reported to get registration spikes during WhatsApp outages and controversies.
• On May 18, 2017, the European Commission announced that it was fining Facebook €110 million for "providing misleading information about WhatsApp takeover" in 2014.
• After financial regulators in many regions raised concerns, Facebook stated that the currency, renamed Diem since December 2020, would require a government-issued ID for verification, and the wallet app would have fraud protection.
• WhatsApp’s voice codec is Opus, which uses the modified discrete cosine transform (MDCT) and linear predictive coding (LPC) audio compression algorithms.
• In a later update on November 30, WhatsApp added a Secret Code feature, which allows those who use locked chats to enter a unique password that hides those chats from view when unlocking the app.

Version History

The feature has to be turned on by the user and provides the option to encrypt the backup either with a password or a 64-digit encryption key. Open Whisper Systems said that they had already incorporated the protocol into the latest WhatsApp client for Android, and that support for other clients, group/media messages, and key verification would be coming soon after. In February 2015, WhatsApp implemented voice calling, which helped WhatsApp to attract a different segment of the user population. Previously the Android and Nokia Series 40 versions used an MD5-hashed, reversed-version of the phone's IMEI as a password, while the iOS version used the phone's Wi-Fi MAC address instead of the IMEI.

Don’t overdo. Just be Whatsapp that was

Since then, linked devices support has expanded and more information is written in the Platform Support part of this article. In November 2023, WhatsApp also began rolling out support for sending login codes to a linked email address, rather than via SMS. This was implemented only on Samsung phones, with plans to expand to Android and iOS "soon".

The DoT expressed concern over not being able to identify scammers who rely on apps like WhatsApp. The government says the new system will make it easier to track fraudulent messages and prevent misuse. Users should not be able to access the app if that SIM isn’t physically active in the device. Under these rules, platforms such as WhatsApp, Telegram, Signal, Arattai, Snapchat, Sharechat, Jiochat, and Josh have reportedly received directions from the DoT.

Previously between March 2016 and May 2017, only limited file types categorised mexican food in toronto as images (JPG, PNG, GIF), videos (MP4, AVI), and documents (CSV, DOC/DOCX, PDF, PPT/PPTX, RTF, TXT, XLS/XLSX), were allowed to be shared for file attachments. In July 2017, WhatsApp added support for file uploads of all file types, with a limit of 100 MB. Voice messages sent this way are deleted after the recipient listens to them the first time. Edited messages were tagged as "edited" to inform recipients that the content had been modified. In October 2018, the "Swipe to Reply" option was added to the Android beta version, 16 months after it was introduced for iOS. In December 2021, WhatsApp changed the default setting from "everyone" to only people in the user's contacts or who have been conversed with ("nobody" is also an option).

Whatsapp is crashing constantly.

In May 2016, some WhatsApp users were reported to have been tricked into downloading a third-party application called WhatsApp Gold, which was part of a scam that infected the users' phones with malware. Since the complete roll out of this feature, users cannot check old messages before this period on the Web version anymore. The company also announced plans to implement reactions, the ability for administrators to delete messages in groups and voice calls up to 32 participants. In July 2021 the company was also testing multi-device support, allowing computer users to run WhatsApp without an active phone session.

In 2016, WhatsApp was accused of copying features from a then-unreleased version of iMessage. According to the Financial Times, WhatsApp "has done to SMS on mobile phones what Skype did to international calling on landlines". On June 13, 2013, WhatsApp announced that they had reached their new daily record by processing 27 billion messages. In 2015, some third-party WhatsApp clients that were reverse-engineering the WhatsApp mobile app, received a cease and desist to stop activities that were violating WhatsApp legal terms. The Saudi Central Bank (SAMA) has prohibited local banks from using instant messaging applications like WhatsApp for customer communication. In August 2021, the digital rights organization Access Now reported that WhatsApp along with several other social media apps was being blocked in Zambia for the duration of the general election.

It was reported that US$3 million was spent in illegal concealed contributions related to this practice. After financial regulators in many regions raised concerns, Facebook stated that the currency, renamed Diem since December 2020, would require a government-issued ID for verification, and the wallet app would have fraud protection. This "Facebook coin" would reportedly be a stablecoin pegged to the value of a basket of different foreign currencies. The project reportedly involved more than 50 engineers under the direction of former PayPal president David A. Marcus.
