Hi Sue, I notice that there are lots of white screen cases with different STR, are thy happening on V2.2 right? Not V2.1, roughly which build does it happen a lot? Thanks.

Hi Eric, Yes, they are happening on Flame v2.2, I did not see it on Flame 2.1

Thanks, Could you help to find out what is the most easy way to reproduce this?

(In reply to Eric Chang [:ericcc] [:echang] from comment #4) > Thanks, Could you help to find out what is the most easy way to reproduce this? I guess this issue is related to performance, because we could not see this bug on user build.

Please make sure modem or fsg files are correct when you flash Flame devices.

Set 2.2? for Crash, regression

I also had this problem when performing v2.2 Gaiatest non-smoketests today. It occurred twice when testing two different features: browser and camera. However, I can pass these cases manually. So, I cannot get the reason now..... will keep finding it if I can. The failed cases: ** test_browser_share_link.py TestBrowserShareToMessages.test_browser_share_to_messages ** test_camera_delete_captured_video.py TestPreviewDelete.test_capture_and_delete_video

This bug results in daily v2.2 Gaiatest test automation failed. So, update the severity to critical...
