Will not boot without a soft reset - Galaxy Note 4 Q&A, Help & Troubleshooting

I got this AT&T Note 4 used, with MM version of android and it had multiple issues, freezing, lagging, ultimate crashing never booting again. I thought it was related to the MM update and downgraded to Lollipop (5.1). Also installed WakeLock app.
The problems seem to have gone away for the most part - no freezing or crashing except that it does not reboot by itself.
You have to remove the battery, hold down the power button for a minute and then it boots.
But if you just shut it down, it's dead. It won't even charge.
Any idea what's going on with it?

Constant Reboot 4.4.2

So my phone was constantly rebooting for about an hour until i removed the SD Card after a hard reboot (Power + Volume Up). A normal Hard Reset did nothing. This has happened several times before, but the problem went away, this time I had to remove the SD Card apparently. I use Apex for my homescreen if that helps at all. I don't use a custom ROM, everything is stock.
Sometimes when it reboots it will instantly go to the DROID boot animation, sometimes no audio would play and it would lag at first for a second, then suddenly it will play the animation at lightning fast speeds.
Another issue is at first, for about a minute or so, I CANNOT lock the screen. I can hold the power button down to get to the power off menu, but not lock it.
Again, The problem has stopped, but it WILL return. I was wondering if anyone can help solve this?
P.S. I'm on Verizon

[Q] After "Power Off", a few seconds after it shuts off, it starts back up again.

[Q] After "Power Off", a few seconds after it shuts off, it starts back up again.
I recently did a fresh install of CM 11 (M12), and I'm seeing that even if I choose to "Power Off" the phone, after a few seconds, it starts right up again.
I don't know if this is a bug in M12, or if some application is causing this.
Does anyone have an idea what could be going on and how I can fix this?
Is you power button functioning normally? That sounds like the symptom of a failed or failing power button. If you suspect a firmware or software issue, the first recommended trouble shooting step is to flash back to stock and see if the problem goes away.
The button is fine. The phone was previously running CM 10.2.1, and I was able to shut it down properly. I wiped it, installed CM 11 (M12), and started installing apps. The next time I tried to shut the phone down, it restarted a few seconds afterwards, and that's the way it's been behaving ever since.
So I'm pretty comfortable saying that this is likely a software issue, and I would think that it's far more likely to be O/S related as opposed to app related.

Do you have a backup of 10.2.1? If so, I'd try that first. Or can you resotre a nandroid on CM? I've hardly ever worked with it or other AOSP. Or reinstall 11 to see if it's just a glitch.
I can always go back or reinstall. This isn't that horrible a bug that it's worth doing that, though, as it doesn't affect normal operation.
I wanted to see if anyone was familiar with it, however, and see if there was a known workaround or nightly fix (the changelogs only show the most recent builds, as far as I can tell).

Random rebooting shortly after 6.0 update starting this week more often.

I have a priv which reboots sometimes 50 times a day, seems to be when the back middle right when holding it screen forward gets really hot. I turned on devel mode with the support personnel and systemui is all that's peaking the cpu when it freezes and then reboots.
same with safe mode, reboots too.
I am backing everything up on a new phone before I factory reset but I doubt that's going to help if safemode random reboots too.
anyone had this issue recently?

Have you recently upgraded your phone OTA (over the air) from software update in phone ?
Marshmallow upgrade.

Phone sometimes restarts into fastboot mode (and other weirdness)

I've been having a weird issue with this phone almost from the very beginning, in that the restart and shut down options in Android almost never work properly. I have seen the following take place:
When I select restart, the phone reboots into fastboot mode. Selecting the "start" option continuously reboots the phone into fastboot. I then have to hold the power button down for ~10 seconds to get it to boot normally.
When I select restart, the phone shuts down but appears to do so incorrectly, as I also have to hold the power button down for ~10 seconds to get it to start up again.
When I select shut down, the phone restarts.
This behavior happened on Nougat, so I tried sideloading the Oreo beta 3 to see if that would help. It didn't. I also did a factory reset after installing the Oreo beta, which didn't help either. I've done nothing to my phone (rooting, unlocking bootloader, etc.) besides sideloading the Oreo beta 3.
Essential support has offered to do a warranty replacement of the phone, but my problem is that I live outside the US and cannot easily send the phone back. Ideally I'd like to figure out the problem as I assume it's a software one, but am not sure what else to do. Essential support thought that the volume buttons could be defective, but in Android they function perfectly (i.e. if there was a problem with phantom presses on them I'd expect the volume to get randomly changed in Android).
The only other option I can see is flashing a full factory image, but since I just did a factory reset after installing Oreo I'd really rather not do this unless there's a high chance of it fixing the problem.
Any suggestions?

That's interesting. My Essential did the restart but shut down thing for the first time today. I'm not rooted and only running the current Oreo 8.0 beta. The only thing I noticed is an update yesterday from the google play store of Essential Services. I wonder if for me they are related.
It's possible but in all likelihood the problem was there before and it just never happened until now. Even on my phone, sometimes it does reboot properly and sometimes it doesn't. I haven't figured out any rhyme or reason as to why it happens. I bet this is a problem that many people haven't noticed because few of us regularly reboot or shut down our phones. For me this has been happening since Nougat, and the Oreo beta didn't change it in any way.

Weird System Bugs/ Issues Stock

Hi, I have owned a One Plus 6T for a few years now, didn't have many issues, until the last few months. I used to be on Android 10. (something) can't remember and the issues I'm about to describe happened on that version too. I have recently updated to Android 11.1.1.1 and the problems still persisted. And I've run a factory reset a few days ago and that still hasn't solved the issues. My bootloader is unlocked and I am not rooted.
Issues:
1. Phone randomly rebooting (almost like there isn't any RAM but there's over a gig spare) eg Ill be listening to spotify and suddenly phone reboots
2. Extreme System UI delay/lag and screen lag. This is the weird one. Happens at completely random times. Phone will slow down extremely to the point where nothing will be responding. For example if I click the power button to look at the lock screen the screen will just stay black for ages. Apps will not open etc. Can barely even swipe or do anything, it happens multiple times a day too.
I was wondering if anybody knew why this might be occurring, considering I am running a fresh install, unless it comes down to just bad software.
