first thanks for your work!
i often use gps (geocaching) and sometimes my display stays black (i only see the backlight? at the bottom of the display) when i press power-button to awake from standby. the app i was using before screenlocking used gps. after this i have to use a combination of holding power and volume-button(?) to force a restart.
this time a was at home and used google maps and switched back to browser. the screen freezed (i see the browser) and display is still on (this happend 25min ago).
this logcat was around 2-3min after freeze: pastebin .com/6BJH5QxB
this another 12min later: pastebin .com/dHTExksA
i hope there are any usefull information or pls tell me how i could create usefull logcats for these freezes on the device itself.
