Bootloop then overheating. - Samsung Galaxy S7 Questions and Answers

I have a galaxy s7 Exynox which is not tampered with or rooted or anything. It is still in perfect intact condition. The better usually takes 14 hours to go down to ~65% after which I recharge at home.
Today I decided to reboot the phone for the second time only since the Android 7 OTA update which I think was over a month ago.
The phone was stuck for 5 minutes at the Samsung logo.
I pressed the power button + volume down for like 30 seconds before the phone powered off.
I waited 20 minutes and then powered it on again.
Now it is overheating. I never let the battery ever go under 60% and the phone never fell or hit anything.
Is there any way I can know what is happening and why it is overheating without resorting to rooting or anything like that?
The phone was bought from a Samsung dealership while on a trip in another country.
There are no Samsung care centers where I live.
Just to be clear, it booted again. But it is charging slower than usual and overheating.

[Q] Nexus 5 Boot loop/other issues

Good evening all, I've owned my Nexus 5 for about 6 months, and yesterday for the first time, I had some issues with it. The phone shut it self off and would get stuck in a bootloop, I was eventually able to get the Nexus into the bootloader, but seemingly today, the phone will restart before I can make a selection.
Unless the phone is plugged in, I can't get any response out of it.. any idea?
Looks like a faulty power button to me since it restarts. Could also be a hosed emmc as well.
Hold the power button till the phone completely shuts down and then try to switch it back on. If it's still the same, time to claim warranty.

Phone died while charging, won't turn on, non-responsive

Phone was working fine at around 7% earlier today when I plugged it in to charging (worked at this time) and went-on playing Civ5 for about 40 minutes. When I grabbed it after that that screen was black and the phone was non-responsive. No charge icon when I plug it in and vol up+down + power doesn't work, nothing works , any help would be appreciated.
Note that I dropped my phone into clean toilet water about 2-3 weeks ago but after vaccuming it and leaving it dry for 30 hours it worked just fine. I don't if this (battery dying?) is related to it.
What should I do? I have plugged it into charging and will leave it so till tomorrow (around 10 hours) and try to turn it on then. If it doesn't turn I will open up the back-cover and look if the battery have corriosoned or anything (is it even possible after barely 2 weeks).
I was thinking about swapping battery if the phone doesn't work after all that too. What is the difference between a LG 2500w D820 battery meant for N5 and an original BL-T9? This is an legit Swedish seller so this is no fake batteries.
How big of a chance is it that the phone will work after me changing the battery if it doesn't work again by tomorrow?
**** I hate this phone but no money to change it.
I have no warranty. My mom who also have an exactly the same N5 has a warranty but I don't think I can use it...and either-way I have opened up the back, it has been in contact with water etc etc so the warranty is void anyway.

Thought my Note 5 died this morning, 4 hours later got it working again

First thing this morning, my Note 5 was working fine. Used the navigation to get to the house I was working at today, as well as simultaneously using Autoguard dash cam app. I got to the job, exited the navigation and Autoguard, got out of my van, holstered the phone.
About 15 minutes later, I try to use my phone to take some pictures, but nothing would happen. Black screen. Couldn't restart by holding the power button. Tried getting into both recovery and download modes. Plugged in the phone to see if it would charge. I was getting absolutely nothing. It was like my device had just up and died. I just kept wondering, could the board have been fried or maybe the battery shorted?
I was dreading the thought of seeing if warranty would cover the device, even after having it for only 5 months. I've been screwed before by the insurance and warranty service on other phones. Making me pay the deductible for a new device, and them claiming that there was water damage, showing me the "damage", when it's obviously a fried board and the moisture sticker isn't activated.
But anyway, lunch time rolls around. I go sit in my van, start pressing the buttons again. Still no restart, still no recovery, but then I try download mode, and viola. Device got into download mode. I canceled out, and the device rebooted normally. I was at 100% power when I got to the job site, and after roughly 4 hours later of it being unresponsive brought it down to 60%.
My mind was put at ease. Charged up normally afterward. The rest of the afternoon there were no more hiccups. Has anyone else ever had something like this happen?

Click to collapse
Yup, has something similar happen to mine. Locked up just like yours while it was in my pocket. No response to anything, even plugging it in to the charger. Just had to hold volume down + power. This is a soft reset and is like a battery pull. Try it out if you have this problem again.

D6603 power off at 80%-70%

Hi Guys,
I have a D6603 unrooted, was rooted before.
Installed a clean firmware 5.1.1, was on 6 and 7 before.
My problem is when i charge the phone 100% it just power off at 80% or 70% with a message of low battery went to 0%
When i power it on again, it stay blocked on the sony logo, i need to put the resest button to make works again, when fully powered, it goes off again.
I tough it was a battery problem, of course it is, but not hardware it's software related, Why? this why:
When the phone goes off on 80%, and reboot and stuck on sony logo, i let it like this to see how many hours it would stay.
And yeah, it took 3 hours on this logo screen to goes off, that' mean the battery still have power.
This problem happened to me when i rooted my phone the first time, unlocked bootloader "was never rooted before until i did"
now even with unrooted i still occur this problem.
I need your help guys; i there's any workarround.
Thank you
i made another thing few hours ago, when the phone is fully out of power, i tried to charge it using my laptop usb port.
It was charging great and slowly, until it reach 50% it jumped to 100% directly.

Do you think this is a hardware problem or software problem?

I have a HTC 10 (new old stock) that I have been using for 2 months, on stock Oreo.
Everything was fine until last week when suddenly in the middle of reading an email the screen froze, a few seconds later the screen went black and would not boot up. Nothing at all, not even with a hard reset VOL DOWN + POWER or VOL UP + VOL DOWN + POWER. Tried holding it for A LONG TIME like 5 minutes, no luck. The phone had a hard brick and that's it.
Occasionally, after a few hours, I would try to reset it just for the hack of it. Or connect it to a charger (no charging light) Eventually after about 20 hours, it booted up again after I held all three buttons for a few seconds. Then it worked like nothing has happened.
It kept running for several hours, I charged it up to 100%, ran down to about 80%, then the screen froze again and died. Same thing happened, won't boot up at all. But if I wait another day or so, kept trying, it will boot up again.
I know the HTC 10 is known for it's horrible battery drain issue, and I have experienced that myself with another HTC 10, this is not it. The battery is running fine on this one. This is something else.
After doing this for a few iterations, I was able to figure out a pattern.
When the screen froze and the phone dies, it will not boot up no matter what you do. But for some reason something is still going on as the battery is still being consumed, a day or so later, when the battery is completed depleted down to 0%, and as soon as it hits 0%, whatever causes it to not boot unlocks and allow it to boot again, as long as you have it on the charger, the charging light will come up at that time, and as soon as it gets a little bit of juice, it will boot up again normally. Except when it does boot up, the date is reset to December 31, 1969 7PM.
After testing this for two more iterations, I am reasonably sure this is what's going on. Then I did a factory reset.
Once it's factory reset, I did nothing except turned on WIFI and didn't do any further setup except surf the internet a bit on WIFI, and about 10 hours later, it died again. Now I know, if I leave it alone for 20 hours, then plug it in for a few minutes, it will boot up again.
So here are my questions.
(1) The phone appears to have bricked during the 20 hours that is was totally non-responsive. What is happening that's consuming the battery?
(2) Does this seem like a hardware issue or software issue?
