Debug Samsung Galaxy S3 Blank Screen Freezes my Samsung Galaxy S3 suffers from the Black/Blank screen freeze. The only remedy is to pull the battery to get the phone to respond again. I'm running Android 4.1.1 and I have done a factory reset. Now the symptoms are back. I would like to figure out a way to get the log of phone after I pull the battery so that I may be able identify which app is causing this issue. I have the Android SDK installed, but so far I can only get the current live log. How can I get a log history with time stamp?

Thanks,

Nick,
There are several system monitors available you might want to give a try. Some of them log activities while running in the background, so no information is lost when the device has to be rebooted. While these might not directly point out the troublemaker, you could still see at what time the freeze happened, and which apps might have been active then -- so they should bring you at least closer to finding the culprit.

One of those monitor apps is SystemPanel App / Task Manager (it has a free trial version, but that does not log in the background but only allows for "live monitoring"). Some screenshots from the playstore for illustration:

An alternative would be System Tuner, which offers similar functionality.
