I happen to have a note4 (samsung). I was trying out new stuff, and I was curious about periscope. After watching someone draw a rib cage for 20 minutes, my phone got exceptionally hot. I can totally live without periscope but it got me worried, should this happen ? I mean I did google it, and I am not the only one who has experiences this, still.. it got very hot to the point of kind of feeling to slow down(but not burn my fingers). should I restart ? or delete some programs from the memory ? what could possibly help with this, and how could I fix it, if I can ? It is not a big issue, still all input on the topic will be appreciated.
My HTC Desire 626s does the same thing, usually when there's more than 5 apps running in the background hogging power. I just clear all recent apps, and force stop apps I've recently opened. Or, like you asked, I just reboot.

Clearing the memory only helps if you have a badly coded app that's hogging CPU cycles. If the heat is the result of using the CPU on good apps only (for example watching vids), clearing the memory will only cause the CPU to work harder when it for some reason needs to reload the apps that you shut down.
One thing to keep in mind is that human perception of heat is a weird thing.
35°C (95°F) feels like little more than lukewarm whereas 40°C (104°F) already is the point where the heat gets so painful that you're not going to hold the phone much longer.
Li-ion and Li-poly batteries generally can handle 50°C (120-ish °F) and mobile CPUs can get a hell of a lot hotter before they get damaged. So just because your phone is so hot that you can't hold it anymore, doesn't mean that the heat is a problem for the phone itself.

If the brightness was set high (more than 50%) and you were using 4G to watch the video I think it's pretty normal. I've found out that keeping the brightness as low as possible usually leads to lower temperatures. A friend of mine has the Note 4 and whenever he plays Pokemon Go with high brightness the phone starts slowing down because of the heat and sometimes hangs.
The important thing is that you're phone is not overheating while charging and while being stored somewhere doing nothing. Other than that I think you should not worry about what happened.

Thank you, I did try getting the brightness down, and I think it helps a little too. And well I found out that I could actually watch periscope on my pc(a little too late) . And even my computer's fans start to turn a bit faster after a few hours of periscope(well maybe not hours... longest I watched someone draw was like 1.5 hour)... so I bet it is totally normal thing for the phone to heat up a bit. I usually my phone to take notes/call/and send messages. This was possibly the first heavy duty app I ever tried, so I panicked .... anyway maybe I am getting old or maybe periscope is not that interesting, I am back to youtube to stalk people draw which doesnt heat my phone as much... Thank you all:)))

Ohh well, this is my 3rd smart phone since last summer (one got stolen, one became impossible to use after I smashed it with a desktop speaker) and I am normal guy who works to pay bills, 3 smart phones a year is too much for me... so I got paranoid and closed periscope after it felt a bit too hot , hot enough to feel a bit uncomfortable in hand in a summer day.
if you don't mind taking your phone apart you can get a sheet of this.
combine it with a little thermal paste on the cpu and it will distribute the heat.
pyrolytic graphite is 2x more thermally conductive then copper. the only downsides are it spreads heat across it's entire surface area and it tears easily. but as long as you don't cover the battery you can expect it to keep your phone reasonably cool at least it worked for my motorola droid 3.

lol yeah, I was planning to type "hot" with capital letters when posting but didn't wanna over empathize how much I loved my phone :p
also speaking about samsung note and hot phones:
SEOUL— Samsung Electronics Co.’s global recall of its newest smartphone after some of the devices caught fire has put a spotlight on the technology giant’s battery-making affiliate.
Well still as a permanent residence of a Middle East country that recently had a military take down attempt, bombings done by much less all the terrorist groups on the planet in my city and the freedom loving PKK, who are of course not terrorist, killing 3-4 people almost everyday to empathize their oppression... I would still take the risk and upgrade, if they give a good discount on the faulty devices...
I use Greenify to kill most of the background processes running and that cools down my phone.
It still overheats when I am in the metro, and my 4G is jumping towers, having trouble reconnecting. While I'm doing that, I just switch to Airplane mode.

I kind of had that too, but in the middle of no where when I was on a bus trip between cities, my phone went crazy trying to connect failed constantly and the battery dropped from 30% to 5% in less than 30 minutes... but I had no significant heating on the phone.
