On 1.3 the screen can go dark for a moment when selecting bluetooth options, but I was unable to make the device's UI freeze.

Was there something that you were playing before hand?

I see a decoder going and then crashing.  I think that's a possible different bug.  It might have helped caused an OOM situation.

When selecting a video to send via bluetooth in the video app the file plays automatically, so yes.

Can we get updated STR here then taking into account comment 3? I don't comment 0's STR shows the whole picture here.

This can also result in an OOM crash if the user tries to send a lot of data (Say, 100 contacts or more) via Bluetooth.

[Jason Smith [:jsmith]]

I don't think the bug's actual results reflect the true state of the phone. The video shows that the UI is still responsive, it's just that bluetooth file transfer is failing. So here's some other things to analyze here:

1. Does the home button still work? Can I still use other apps?
2. What's the recovery path for this bug? Could I kill the gallery app & restart it to workaround this?

See also bug 996912, another sending file OOM on Tarako.

Lionel needs to come back with a response here to clear the qawanted field.

As shown at the end of the video the HOME button still functions.
Other apps can be launched.
The app can be killed and restarted.

Can we verify this on the Moz side as well? There has been a bunch of changes that landed here recently.

[Mike Lien[:mlien]]

I verify with today's daily build and it's fine
no unresponsive after repeat send file 15 times.
