I have seen this also.   Although I'm ultimately able to find and access a network, this can at least create a perception problem (feature appears not to work, even though it actually does.)  Nomming.

Dear Jeni.

The screenshot showed 'searching'.
It means the manual search isn't done yet.

Sometimes manual search takes more than 1 min ~ 2 min. ( It depends on network environment )

But the log captured just 1 min after starting manual search.

07-02 10:01:35.109: I/Gecko(145): -*- QCContentHelper_QC_B2G: receiveMessage: 'RIL:GetAvailableNetworks' arrived from content process // start manual search
07-02 10:02:34.999: I/ONCRPC(148): oncrpc_proxy_handle_cmd_rpc_call: Dispatch returned for xid: 564 // The last line of the log.

1. Please wait more than 2 min after starting manual search.
2. Capture the log more than 2 min after starting manual search.
3. capture modem log ( QXDM log ) if it is possible.

It is not reproduced with Leo version.
Please check with origina leo version.

It seems to be that the RIL interface is different with test version and leo version.

The log attated showed to me it's not leo RIL interface.
Still repros on Leo 1.1 commercial RIL.

Please attach the new log in comment 8.
mvines, is there a new RIL we should be picking up? sounds like leo can't repro with their comm_ril, but we can.

Does this issue reproduce with the unaltered partner image using that particular device/simcard/location?

Issue no longer seems to be occurring on the latest Leo build from the commercial v1.1 branch:

After disabling automatic network selection and waiting for about 1 minute, the list populates with several options. I'm seeing the following options: AT&T, 31026, and GSM.

Resolving issue as works for me.

Using the Leo partner build from June 20th on three devices, we were unable to repro this issue.

We were able to repro the issue on two out of six devices, one of which was on the 07/17 com ril build and the other being on 07/18 com ril build.
