Well, well, well...just when I was about to "give up" for a bit I stumbled across something that I think I have
CONFIRMED with regard to my ability
to replicate my hot reboot situations!!
I was playing with my phone for a solid 10 or 15 minutes
straight while I was watching TV...and NO reboots. I was constantly using my phone either swiping or flicking or touching...whatever I was doing, I was interacting with the phone. I have mentioned in previous posts that it appears that my reboots happen while my phone is IDLE, not being touched, not locked and screen on.
Well, I kinda zoned-out from my phone and had it in front of me while I turned my attention to the TV and noticed that my phone rebooted

I said to myself, "I was using my phone for like 15 minutes and then it couldn't have been more than 2 minutes sitting here and I get a reboot??"
And then something hit me...."about 2 minutes"...hmmm...that "about 2 minutes" is the time that I have set
for my screen time out!! After reboot I went through my phone for the only app I was familiar with that read and showed log information, System Tuner by 3C:

I launched System Tuner and clicked the "Logs" option and started watching the logs scoll, taking SPECIFIC NOTE of the TIME that the logs started. That corresponded to the VERY LAST BUTTON I pressed on the phone. IN other words, after starting the log view, my phone was "idle" with the screen on. If my thoughts are correct, a reboot could be coming...
SURE ENOUGH within about 10 seconds of the 2-minute mark for my screen time out....
WHA-BAMMO!!!...REBOOT!!!
I waited for the phone to come back. This time I CHANGED the screen timeout to 1 minute...again, a few seconds before the 1-minute mark,
REBOOT!! I tried again with 30 seconds...
SAME THING!! I also tried the 10-minute timeout option and though I didn't wait until 10 minutes to see what happens,
the 2-minute mark and BEYOND was reached WITHOUT a reboot.
SOOOOOO, it appears that, for me, that MOST of these hot reboots can be replicated to occur just a few seconds before my screen is to time-out as set in the Display settings. I say "most" because I'm pretty sure that a few hot reboots have happened while in the middle of using an app or while the screen is off and locked. However, perhaps my thoughts with regard to the reboots prior to the screen timeout trigger related to these other reboot situations.
But
HERE IS MY PROBLEM....I need someone to point me the direction of an app that will record ALL the log files so that they can be reviewed. This System Tuner app can save the log files but NOT in an automated fashion. The user my PUSH the "save" button. PROBLEM is that it is IMPOSSIBLE to click the "save" button as a point to capture the reboot log process information. I can "see" the freeze and pending reboot and the "save" button is non-responsive...and then the phone just hot reboots. When the phone boots up and I check to see if the log file has been saved, it is NOT
So, I know log files can be saved and looked at. Can someone point me in the direction of an app or technique to retrieve the log files so I can get them to the dev??
I'm HOPEFUL about this latest discovery!!
THANKS!!
