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?
