We are currently having issues making 911 calls on phones using v81 firmware, but if the calls are made using v80 they are working fine. I have a T46S with 81.0.20 firmware, the S model does not offer firmware other than version 81. Once the G models were downgraded to v80 they were fine. This was also the case on the T41P's. Any ideas of ways to resolve this issue?

Thanks.

Can you tell me what's your detail test steps?

and could you help to get the config.bin/level 6 log/config.bin files of S model and G model， then we will make a compare.

About how to get these files, please refer to this FAQ:
