Facebook pushes mobile users to Messenger app

Android users logging on to Facebook via the web browser are reporting seeing this message.

Facebook users on Android devices are being notified that they will no longer be able to access messages without the Messenger app.

The function for members to read messages by accessing the social network on a mobile phone web browser is being disabled.

A message currently appears informing users of the coming change. On some handsets the Play Store then launches.

Facebook said the move is an extension of its 2014 Messenger policy.

"Using the Messenger app is faster and enables richer interactions. We're continuing to bring the best experiences we can to the 900 million people on Messenger," it said in a statement.

Messages are already inaccessible via the official Facebook app.

However, Devin Coldewey at technology news website Tech Crunch described it as "a hostile move".

"Surely the mobile site is much used by people who have good reason not to download the app," he wrote.

Some users have complained that they do not wish to use the app, citing battery life and privacy concerns.

Revenue growth

Analyst Martin Garner from CCS Insight told the BBC messaging is a key area for the company.

"This move underlines what an important platform messaging is becoming for Facebook," he said.

"Messaging is undoubtedly the next growth driver for revenue but it also will be key to developing highly sophisticated artificial intelligence solutions.

"People will get used to a dedicated messaging app despite their initial objections. Facebook just needs to make sure that the app is well-written and does not start becoming a big drain on battery life."
