I didn't, but making it a requirement to enter your phone number to use the app with no mentions of what the privacy controls for people being able to message you with just your phone number are made the new app a quick uninstall.

Facebook, you've had enough privacy problems in the past, is it really that hard to outline what's going on here or even just not require the number? I've heard that GVoice numbers don't work, as well, which just makes it even worse.

The nice thing I've found about using the Messenger app is that it seems to put a lot less strain on my battery, especially after I disabled location services for the Messenger app. I like being able to disable location services in Messenger, but leave it enabled in Facebook. I don't really care if my location is tied to IMs (and often prefer that it's not), but it's usually nice for Facebook status/image posts that are essentially check-ins on the go.

Agreed, I had to remove messenger because of that - it annoyed me that much.
