According to Android Police, you will be able to send text messages from your browser, quite soon at least. Whilst conducting AKP teardowns of the Android Messages 2.9 update, it was observed that a browser texting functionality is present.
The feature seems just like Google Allo except for one significant detail. While on one hand, Google Allo does allow messages to be exchanged online, it seems that Android Messages is taking things to the next level by introducing this to SMS text messages, eliminating the need for an internet connection which is fundamental for Allo’s web messages. The update is not here but most major browsers such as Google Chrome, Microsoft Edge, Firefox, Opera, Safari and Internet Explorer are expected to be integrated into the update.
Experts predict that the new feature will be implemented by using the mobile app to scan a QR code provided by a dedicated Messages web page.
The update certainly seems to be attracting attention and can very well be a possibility in the future. However, as of today, there is no word on Google if this feature is confirmed or when the next update will arrive. For now, let’s rely on web messages.
