If you believed that WhatsApp text message that you recalled after accidentally sending it to the recipient can't be viewed, then think again.

WhatsApp users can simply download a third-party app called Notification History to read deleted messages.

WhatsApp ‘Delete for Everyone’ feature was rolled out a few days back. It lets users delete or recall sent messages within seven minutes of sending them. Now Spanish blog Android Jefe has discovered a way around this feature, and claims that deleted messages on the device can still be accessed by the recipient.

According to the report, users running Android 7.0 Nougat or higher version can simply download a third-party app called Notification History to read deleted messages. It is important to note that it only works for deleted text messages, and not photos, videos or any other media. After downloading the Notification History app from GooglePlay Store, users should be able to see message that has been deleted in the Android Notification log.

“What we found is that the messages are stored in the notification register of the Android system. So, it’s just a matter of entering that record to see the messages that the other person deleted. The Notification History application is a shortcut to that record,” the post reads.

The process is even easier for people using third-party launchers like Nova Launcher. In this case, there’s no need to download a third-party app to access deleted messages. Just long press the home screen, and then click of Widgets. Next, tap on Activities and then Notifications log to view notification log of the system. For people running stock version of stock Android, a Settings widget will give them access to notification log.

WhatsApp adds new ‘Delete for Everyone’ feature;here’s how to use

Remember, there are certain limitations to viewing deleted messages. Apart from the fact that only text message can be viewed, the blog post clarifies that just the first 100 characters of message will be visible to users. Also, only messages for which a user has received notification can be seen. Further, the messages are apparently stored for a few hours on the device and are deleted if users restart their device. Finally, doesn’t look like it works for devices running Android versions older than Android 7.0 Nougat.

So if you believed that text message that you recalled after accidentally sending it to the recipient can’t be viewed, then think again. However, you’re safe if you accidentally sent a photo or video to someone you shouldn’t have, and deleted it afterwards. WhatsApp ‘Delete for Everyone’ was one of the highly anticipated features, simply because it gives users a chance to correct their mistake. It was made available globally earlier this month.

Scientists have created a new artificial intelligence system that can identify a range of emotions – from happiness to disgust – in human speech. For a long time, computers have successfully converted speech into text. However, the emotional component, which is important for conveying meaning, has been neglected.

Neural networks are processors connected with each other and capable of learning, analysis and synthesis. This smart system surpasses traditional algorithms in that the interaction between a person and computer becomes more interactive. Systems in a neural network can learn from their own experiences, and conduct future actions through the data points that are tacked with time. This data enables artificial intelligence in these systems, and creates capabilities to interpret more complex inputs with inferences from its own past experiences and previously stored data.

Researchers at the National Research University Higher School of Economics in Russia trained a neural network to recognise eight different emotions: neutral, calm, happy, sad, angry, scared, disgusted, and surprised. In 70 per cent cases the computer identified the emotion correctly, say the researchers.

The researchers have transformed the sound into images – spectrograms – which allowed them to work with sound using the
methods applied for image recognition. A deep learning approach was used in the research.
