At the end of last month, to the undoubted delight
of many users, WhatsApp began rolling out a long craved-for feature: the
ability to “unsend” those messages that you almost instantly regret as soon as
you hit the Send button.
The feature, which was rolled out on the latest
versions of WhatsApp for iOS, Android, Windows Phone and desktop, simply
requires the regretful messenger to tap and hold on the offending message,
choose “Delete” and then select “Delete for everyone”.
As long as you did this within seven minutes (and
the recipient was also running the latest version of WhatsApp) the message
would be successfully deleted, the company promised.
But, if there’s one thing we should all have learnt
from our years on the internet, once you say something somewhere – it’s very
hard to take it back and pretend it never happened.
And there’s good reason to not get too excited
about WhatsApp’s new “Delete for everyone” option.
Although it promises to zap the embarrassing
messages you’ve already sent to one of your contacts, the truth is that they
may not actually be gone at all.
Within days of the new feature being incorporated
into WhatsApp, the Android Jefe blog
found a way to read “deleted” messages.
On Android, WhatsApp messages are stored in the
device’s notification list – regardless of whether they are subsequently
deleted by their sender or not. All a user has to do if they wish to remind
themselves of a “deleted” message that they have been sent, is check the
notification log where the first 100-or-so characters are stored.
If that’s too much of a palaver, there are even
apps in the Google Play store that will provide a simple clickable link to to
the notification history.
It’s important to stress that Android Jefe did
find some limitations in its method of viewing “deleted” WhatsApp messages:
·
Only messages
that have already been seen or interacted with can be retrieved from the
notification log. This does include any interaction with a WhatsApp
notification, so the message itself does not have to have been opened.
·
Only text
sent via WhatsApp can be “undeleted” in this way, and even then it is limited
to the first 100 characters or so. The notification log will not contain any
images that you were sent.
·
Only messages
that generated a notification will have created an entry in the notification
log – logically enough. In other words, if you were chatting on WhatsApp at the
time the message was sent a notification will probably not have been created.
Nonetheless, it feels like this discovery is a
timely reminder for all of us that once we send a message it is effectively out
of our control. Always think hard before pressing “Send”!
Oh, and while we’re on the subject, Android Jefe
also found a way to “delete” WhatsApp messages up to 7 days (rather than
7 minutes!) after they were sent, by simply fiddling with their
smartphone’s clock.
