We have a DX-650 deployed for one of our executives. The phone screen flashes every couple minutes. It sort of looks like an application opens then closes instantly -- this causes the screen to brighten and then dim. As you might imagine this becomes quite obnoxious.
Is anyone else experiencing this?
Any thoughts on what I could check to see what is causing it?
Pulling the console logs from the phone's webpage may give some input into which application is launching causing the issue. Logcat log file is what would have that info.
Do you have multi-user enabled on the device?
These look like the normal console log files. I think there should be a file named logcat as well. You may have to try creating a problem report on the phone right after the issue occurs- http://www.cisco.com/c/en/us/support/docs/voice-unified-communications/unified-communications-manager-version-91/116457-qanda-dx650-00.html
I believe multi-user is enabled (I remember setting that), but there is no second user configured. I am not seeing any log named logcat - any idea where I can locate that?
I have obtained the logcat log - any idea what I am looking for here?
These are the only items that caught my eye:
00569 08-04 15:15:00.945 2398 23106 DEB SyncAdapter: onPerformSync: Perform Sync automatically.
Looks like there's a failed UDS contact sync in there that might be worth researching. I still see it referencing EM dialogs so it might be a good test to turn off multi-user and reset the phone to see if that changes the behavior any.
Try Upgrading the Firmware of the Phone. I think this is a known issue in DX650 and Firmware upgrade will surely help.
