1. turn on wifi debug, and enable console in dev settings 2. have the battery at around 20% 3. make sure that the device is not plugged in 4. go to news.google.com 5. click on a link 6. let the device go to sleep 7. tap the power button to wake the phone Expected: the device will wake Actual: the device stays black. Note: 1. this doesn't seem to occur with wifi debug off and console is disabled.

I am not noming this, because I don't expect end users to turn on the wifi debug nor enable console.

By your test steps, I am wonder this is back screen issue or device shutdown. Is there any response when we insert charging cable after issue happened? If it's device shutdown, we should see the charging animation after cable in. Moreover, is there slog for analyzing?
There was no charging animation; I think it was a back screen issue. Once I plugged the device in, it would start responding. Unfortunately, I don't have a slog. The last slog I have is from 5/30
Is there a way to manually capture a slog?
or would logcat be ok? My battery is fully charged today so I am not sure if I can reproduce at this time.
Slog is enabled on userdebug build and please must insert SD card. You can use below command to get slog #adb pull /sdcard/slog slog If device hang and black screen, you might be unable to connect adb and get log successfully. If adb cannot be connected and no charging animation, please restart device and get slog again, we can check last_log of slog. If it's out of battery to cause device shutdown, you will see battery animation when you attempt to connect device via usb cable. In this case, please remove the battery and get slog from SD card directly. Slog is better, slog included kernel log and logcat.
Hi James, Do you know the format of shutdown and battery log in kernel log?

I tried several times at battery is about 14% low and everything is OK. Please make sure it is not because of battery loose. As for the shutdown and battery log in the kernel, the keywords may be shutdown, battery_update, PM.
I can't seem to reproduce this using a more recent build. I'm not sure what occurred.

Is that ok?
