Note 8 stuck on home screen "Android is Starting. - AT&T Samsung Galaxy Note 8 Questions & Answers

So from time to time, more so recently, my phone will sometimes boot up and then not fully finish booting. It works, but is very sluggish. The "Android is starting" animation shows and then disappears. My phone will then seem to have a UI crash. The notification light turns solid blue and it boots back to the ATT logo, then I have to insert my password again. I haven't modified anything on my phone, 100% stock.
One other thing, when all this is happening, apps installed to my EX-SD card are unavailable. Any thoughts?

How to restore into operation LG G2 D800 phone that says "Fastboot mode started"?

How to restore into operation LG G2 D800 phone that says "Fastboot mode started"?
Current problem: phone is not operational (does not boot properly).
What I see:
Boot Screen 1:
Phone appears to boot as normal, makes the start-up sound, then it shows a white message box on a gray-screen background. The message box says "Unfortunately, Settings has stopped."
It gives me an option to click "OK".
Clicking OK, message box disappears, screen momentarily flashes an all-white background, (which sometimes changes into black and sometimes not), and then it goes back to the message box.
Boot Screen 2:
"[xxxx] Fastboot mode started" on a blank screen,
where xxxx is a number. 6180 one time, 9790 another during 2 individual boots.
Then the phone just sits there doing nothing seemingly indefinitely.
I am not sure yet how I bring those two different boot modes up but via pressing Power and / or Power and Down buttons in some fashion.
How do I fix this? Is my device bricked?
How I got to that screen
I was using a web browser or some other app on the phone when I have received a text message. I clicked on it inside text box to reply. But changed my mind, and clicked back on the background app. Suddenly the phone shut off unexpectedly. I thought it was related to phone drawing suddenly high battery power, not receiving it and shutting off as sometimes happens on very low battery power level 2-4%. However, my battery was charged over 40% so that was most likely not the cause.
Possibly relevant history (anything that could be contributed to the above):
phone worked okay for a while (since purchase)
~1 year in I tried rooting phone with towelroot/other options unsuccessfully. Gave up. Was never able to root the device. Lived with is as is for a while.
~2 years since purchase, somehow Bluetooth option started failing to turn on. Trying to fix that via doing a Factory Reset did not help. So I lived with BT being non-operational
A week ago I swapped SIM card with my buddy for a week, then swapped it back. Phone kept working as normal.
Today I charged the phone perhaps not using the best power source - it is possible I may have damaged phone using a questionable quality charger. Possibly. This could be the issue. However the phone seemingly worked fine after that for 2-3 hours.
Since my unexpected Shut-Off (most recent), I tried rebooting the phone, but that does not work as expected. First time it got stuck on LG screen forever. Kept pressing Power button, or Power & Down buttons to try to make it come alive. Other two times it brings up a message with "[xxxx] Fastboot mode started" on a blank screen and then it just sits there doing nothing.
Another boot, the process went further, past LG G2 logo, into white screen, and then it brought up a message "Unfortunately, Settings has stopped.", I clicked okay. It looped back to bringing up the message. I clicked Okay over 10 times, it was stuck in a loop.

XT1033 showing unusual behavior. Keeps rebooting and keeps hanging

This happened yesterday. I was on CM 13. Everything worked fine. But now, the phone kept rebooting whenever I ran an application. What's worse, it started hanging for 5 minutes and even the power button didn't respond, after which it heated and then rebooted.
I flashed the stock ROM 5.1 Asia retail and the phone said,"Starting apps 1/76" and when it reached 76/76, the phone rebooted. When I tried opening recovery, the phone showed a black screen and kept showing the bootlogo, going black, bootlogo, going black, and again.
I've tried installing other recoveries but the same thing happens.
Basically, the phone is dead.
The only thing that works is bootloader.

G920w8 black screen after update

This g920w8 has black screen that happened after some update. I can get screen on when going to download mode and can finish the process but when the phone tries to turn on after updating apps it gets stuck on black screen with blinking blue led. Tried few stock roms but at no avail. Tried rooting it and installed TWRP, cleaned practically the whole system and reinstalled new one but the problem remains. Sometimes the phone gets stuck on starting apps after flash and the cogs are spinning but the phone never gets past that point.
Thanks

J3 stuck in boot screen. [Tech Support]

Hi, I just made an account here because someone on Reddit suggested it. I am having an issue with my cheap Samsung phone. It is a J3 Emerge and I have had it for about 3 years now. About 30 minutes ago I was watching a youtube video when suddenly my phone turned itself off randomly without me having pressed the power button. The battery was at about 30 percent. It didn't do the normal turn-off sounds, it was just on, then a black screen, then the boot screen. When my carrier logo pops up it doesn't play a sound, when it normally does. It then stays on my carrier logo screen indefinitely and vibrates a couple of times every 20 seconds or so.
I have tried taking the battery out and putting it back in, and then turning the phone on. It turns on normally, but after the carrier screen, it goes to a teal blue background that I have never seen before that says "Starting Android" at the top, and "starting apps" at the bottom. After about 10 seconds, my home screen comes up. Once my home screen comes up, after about 3-5 seconds it turns off and starts the process mentioned above. I tried booting it into safe mode, and the boot was normal until it got to my carrier screen, made the sound, and then was stuck in the indefinite vibrating loop.
The only other option that I can find is to try to factory reset it. Though I know that we are switching our plan over to T-Mobile very soon, and I'm wondering if I should wait until I go see them for the new sim card to see if maybe they can fix it. I don't want to have to get a new phone if I don't have to. Even though my screen has many cracks, and it can be really slow at times with android 7, I don't mind it.
I'm willing to try just about anything at this point. I'd also be relieved to know if this just isn't something I can fix/is fixable, as at least I wouldn't be in the dark. If you have any other questions please feel free to ask, I will provide as much additional information as I can. Thanks in advance.
