Facebook forcing Android users to download its Messenger app, chat on mobile site going away?
If you go on facebook.com from an Android phone and try to access the messages tab, you'll be greeted with the following message:
You'll only see it for a split second, before you are redirected to the Messenger app, if you have it installed, or to the Play Store to download it. You can go back and see the message in its entirety, but there's nothing much to look at. There's a big blue button prompting you to go to the app and an “x” tucked in the right upper-hand corner of the screen. Tapping the “x” takes you your conversation list, but if you tap on one of them – cue drum roll – back to the Play Store with you! You can backtrack and tap the “x” button again which will finally let you message someone but at this point the effort is not worth it, in our opinion at least. But hey, you can try to use the desktop version of Facebook on your device.
This scheme seems to affect Android users only, as our tests have confirmed that the mobile version of Facebook on iOS and Windows devices has no such trickery up its sleeves... for now.
