[Verizon Galaxy Note 3 Q&A, Help & Troubleshooting] jcoltrane890:
Read through at your own risk.

Pmfji, but I have had a similar experience. Set up my Note 3 to charge one night, went to sleep, woke up and I could fry a virtual egg on it. The temp was some ridiculous number I can't recall. Totally freaked, thought the thing might explode. Mind went into overload, gotta figure this out, before it burns out!

Kept repeating the mantra, "this is just a computer", over and over. In a former life I used to be a 'Wintel' power user or so I used to think. :rolleyes:

Racing through all the possible scenarios, what could be the issue? I checked my tools, not only was the temp outrageous, but the CPU frequency was through the roof as well! Noting the super high temp over a long period—a few HOURS; finally, I thought to pull the battery.

For those who know, not an easy effort given a Zerolemon case (think Outterbox) and humongous, heavy battery amidst visions of seared flesh! ?

Battery out, I could think more clearly. Letting the thing sit and cool for a half hour or so. I sat hoping, whatever the issue, the battery pull killed it. While I struggled to put my foggy brain into overdrive. Not the way to start the day, before breakfast and before my first cup of coffee! Imagine, wake up, grab the phone, cut the alarm, then ? wtf!

Thinking on it, I figured it had to be a problem with some very recent software installed on my—Rooted, Xposed, and otherwise stock Note 3. Could it be one of the Xposed modules??

I had, a couple of days before, after a short stint with 3c's "Battery Manager", swaped it for 3c's "Toolbox Pro" (which among MANY, MANY, MANY tools includes the Battery Manager Pro).

Daunting, comprehensive apps both, of which my primary focus was, at the time, facilitating the Battery Manager so it would provide relatively useful and accurate readings of the Zerolemon's 10,000 mAh battery level at any given time. An effort which was driving this tinkerer absolutely batty! ???

So, after several courses of, pull the battery, think a little, place the battery, watch, feel the temps rise, and pull the battery, the damned thing just would not stop! Finally, I used Toolbox Pro's "CPU Manager" and "Task Manager" to determine which app was monopolizing the CPU percentage use/time; and, concurrently causing the insane CPU frequency, and ultimately frying my phone. Needless to say, the device was not only super hot, but irritatingly sluggish which made this a tediously slow process.

Anyway, culprit found,Titanium Backup and that app was history. Actually, that may have been my first use of Toolbox Pro's "App Manager". One or the other….

Which app was it? Unfortunately, I do not recall, maybe a record is in the logs. How high did the temps go? Again, can't recall, I can vouch it was higher than any temp I had experienced on a Note or any computing device. How's my Note 3? Well it was, well—fine! Showed no consequences, nothing.

That is til I screwed the sound/volume (Wanam and another Xposed module poorly coincide when both utilize the volume button to trigger different functions), but that's another story.

For the record, I am on my FOURTH Note 3!! My present and last Note 3 is suffering the same sound/volume issue, a tinkerer's fortune. Though my first ROM flash should correct that issue.

Hmmm, now how do I flash?? Odin (isn't that a Norse g_d?), TWERP (isn't that some sort of butt humping??), SafeStrap (isn't that a sexual device hung from a ceiling beam??), duhhhh another confused newb….

Thanks to anyone bothering to read through the above.
