If a user tries to send a MMS on a slow network connection, the phone will stop responding to touch. The lock button and home button will also stop working. The user will have to remove their battery to turn off the phone. 

Repro Steps:
1)  Updated Buri/Inari/Leo/Unagi to Build ID: 20131212004004
2)  Ensure the user is on a very slow network connection and tap on the "SMS app" icon.
3)  Tap on the "Compose new SMS" icon.
4)  Enter in a valid phone number into the "To" field.
5)  Tap on the "Paperclip and tap on "Video". 
6)  Tap on a video to attach it to the SMS and then tap "Send".
7)  While the MMS is sending try touching the screen and also try locking the phone.
8)  If the phone is still responsive, attach another video to the same MMS and send it while the other one sending.

The phone will become unresponsive to all input. The user cannot even lock the phone using the top button on the buri or go home the device. The user will have to remove their battery.

The user does not lose functionality from sending a MMS on a slow network.

Please note that i could only reproduce this with data turned on and WiFi turned on. WiFi barely had a connection as in one signal bar. Cell Data had no signal bar showing. I could not reproduce this issue with having WiFi Turned off and data having only one signal bar.
This sounds terrible, even if the use case is rare.

I'd say this is more a RIL issue here.

Could this be a Comm RIL issue only? Can you test with MozRIL ?

This issue only reproduces on the Com RIL. We tried multiple times on Moz RIL but were unsuccessful in reproducing the issue.

Not sure, old ril + new gecko/gaia = PORB (part of random build ;))

Hi Michael, would be an old RIL for 1.2?  Is there a location where we can download the latest ril?
Flags: needinfo?(nhirata.bugzilla)
Yes, .102 is quite old (early Nov).  Currently no location for newer ones though, sry.
Thanks for the info.  Please let us know when the next version is released.  Otherwise our tests will be invalid.  :(

Was getting this issue last night on Buri 1.3 Moz. Here's the variables-

attaching a logcat of an attempt to get this issue to occur, phone froze up slightly during this attempt, but did not completely lock.

To be clear here is the STR that I used to get this issue to reproduce.

1. Updated Buri to Build ID: 20140121004137. 
2. Open the messaging app.
3. Tap on a short code number to reply. (a message from an automated source.)
4. Attach a picture message and tap send to reply.

Phone locks up to varying degrees, message takes an extraordinarily long amount of time to send.

Phone sends message and does not lock up.

When I first got this issue to reproduce last night I had to remove my battery to fix the issue, as no other method would end the lock up.
If the message fails to send and the user retries to send the media, the phone will suffer noticeable slowdowns until the message is sent.
Milan, can you please check whether the log in attachment 8365231 [details] shows up some graphic-related issue?
Flags: needinfo?(milan)
Could be two different bugs; the new log shows us using the graphics memory to exhaustion, and falling to system memory.  Previously, the graphics operations would just fail, so a lock up may have been an end result of that, in the December version.
With the latest version, and message taking a long time, it really sounds like bug 962142, and it fits into the "regressed on Jan 18th" time frame.
Flags: needinfo?(milan)
Yeah, right, I agree these are probably different bugs since the first one was vendor-related.

But how the graphics memory could be hogged? The spinner animation?
We use canvas whenever we need to send an image blob out.
