Why does my S4 Overheats when I use the flashlight app?

[Cappuccino]

I use it when I watch streams online (In the dark).

Go test it yourself, give it 10mins your phone will turn into a fryer.

So, why does it do that? I'm scared that my S4 will blow up.. Help?

The LED flash on your phone is only designed for momentary output.

By running a flashlight app, you're using it in an unintended fashion. LEDs generate heat and draw a lot of voltage from your battery (which also generates heat from the increased power draw).

In short, if you need a flashlight with a long runtime, buy an actual flashlight: http://www.amazon.com/FordEx-Group-3...dp/B006E0QAFY/

lol. I'm using the flashlight as a table lamp hahaha

Thanks anyway. Also, is it safe to use? I use it for around £1-2.

No I'm watching stream on my Laptop and use my S4 as a table lamp.

Ummm.. Why?

Organic LED brightness is a function of how much power it draws and how much heat it outputs (LCD phones don't work this way). Thus if you have the screen brighter it will get really hot. Furthermore this is not good for the Organic LED for they have a maximum life span and the more you use it the quicker the Organic LED decay.

Yes your phone is convenient, but you should probably have a different light source if you are using your phone as a light source for 10+ minutes.

Ummm.. Why?

The light I have attached on the ceiling is to bright.

Since when do people watch movies in bright conditions, in their bedroom? I like my light dim when I watch movies and TV series, hence why I use my flashlight app. (Yes I could buy a table lamp)

Since LED's have a limited lifespan, it seems like a $10 lamp is the wiser choice...Or just wank in the dark.

I prefer to just turn off any lights.

Why don't you get a real lamp? You're risking damage to an expensive phone to be penny wise and dollar foolish.

I am! That is why I made this thread.

Wow!

Smart phones, dumb users.

Who you calling dumb? You dumbass! I'm not a tech nerd like you!

I dunno, I just assumed that most people would assume that running what was included in your phone as a camera flash as a table lamp would be a bad idea.

I shall adjust my idea of tech nerdery downwards accordingly, to just above total idiots.

Mmmm, they are also designed for constant output in video mode...

But yeah, as a lamp? I wouldn't use it for that. Stumbling through your place in the dark, trying to see underneath something, sure. But not "turn this on for the next 2 hours." :awe::biggrin:

My mom once had Candy Crush running for over 3.5 hours on her phone. She went out to meet me and we went to her house and I found her S4 sitting on her coffee table running that game the whole time. It was so hot that I thought the phone might have been damaged. Thankfully nothing wrong happened but I told her to be a bit more careful. I was surprised that the stupid game did not drain off the battery completely while sustaining that much heat.

It's OLED. You're pushing it to its very limits because you are asking for

1) White colors

2) Very high brightness

Unless you want a $600 paperweight, better get a real and cheap flashlight.

Are you guys sure the flash is OLED, and not plain LED? As to the heat issue, I noticed this once on my Nexus 4, after I apparently triggered the flashlight lockscreen widget while it was in my pocket. The phone got pretty toasty.

Well, that's minor carelessness. Using your phone's led as a table lamp specifically when you're watching web video? That's just weird, and stupid.

I have to agree with this. Buy a lamp or watch your laptop in the dark.

Why the hell should candy crush overheat a phone? This is what I don't get. I can surf the web or play Temple Run 2 and my Nexus 4 gets hot. I can play Temple Run 2 for hours on my iPhone 5 and its nowhere near toasty.

Poorly coded for Android perhaps? You should see what Candy Crush does to a Macbook Air. Instant hair dryer.

Heh, Youtube made my old 11in Air inter a fryer. Ultrabooks that thin don't much the most robust cooling system, and Apple neglects cooling for sake of pretty design.

My HTC One would go all flame on when I ran navigation and kept the screen on. Actually there were several scenarios where the One would be burning hot. Complete opposite experience with the Note 3 thus far, it's never gotten hot.
