So how can I see the logs in Jelly Bean?

Question

I used to use an app called Log Collector to see system logs. It would send them to my email or via bluetooth,

However, on Jelly Bean the "read log" permission for apps no longer exists and apps can't read the logs, and Log Collector is obviously no exception.

So does one now need to root the device to see system logs? There must be a way for the user to read them. I don't need to access them from an application, I need to read them as a human being. Is there a way?

I got the answer in this google groups thread: https://groups.google.com/forum/?fromgroups#!searchin/android-developers/READ_LOGS/android-developers/6U4A5irWang/8xOi74KfRIYJ

the message by Mark Murphy replying to Matteo Sisti Sette (which is me).

(it doesn't seem to be possible to link to a particular message, is it?)

POWER + VOLUME_UP + VOLUME_DOWN will generate a report and a screenshot that you can send via email or upload to Drive (ridiculous you can't share it in an arbitrary way such as send via bluetooth or open as text file, but anyways).

(seems you have to hold them for a while and the action is launched when you release them)

At first I thought he was making fun of me and that would just reboot or something, but then I tried and it works.

Quote from Google+ and credits to +Ian Clifton :

"If you go into the developer options of a device running 4.2, you can check the box to add the Bug Report option to the power menu. This also adds it to the quick notifications menu (not sure of the proper name, but slide down the notification shade with two fingers on a phone or on the right side of a tablet)."

..and that would be right answer.. Cheers
