What's wrong with my GALAXY S3?

There was something in the news, recently, about how the FB app is “phoning home” with a lot of tracking data. Big privacy concern.


Yep. If you had FB Messenger installed, they would put an alert on the top of your Facebook App (when opened) and said to not listen to what you hear, and then they give you a link to click where they tell you what the REAL scoop is. Didn’t bother with it. Doesn’t matter to me. If they want to track you, they can. Too much technology tracks you. They’ve already gathered enough data on me. They know my habits.

That happened to me too. After two days I got rid of the FB app. I don’t need to be informed in real time if someone posts something on FB. I’ll check myself using the browser when I feel like it.

hitting the middle bottom button and holding it in will bring up all open applications).
[/quote]Nice, didn’t know that. Thanks for the tip.

On the S5, holding the middle bottom button opens Google Search. LOL!


Yes that was frustrating to learn when I got the S5. No idea why they changed it. Actually tapping the left button brings up the open applications on the S5. Normally S3 would have the left button bring up a settings menu, but S5 doesn’t.

@guido2004 you’re welcome.

First off, thanks to everyone who replied and shared their opinion.
I don’t use the phone while charging, but did have applications like Facebook Messenger, Clean Master and Doctor battery on my phone.
The Samsung service centre told me, the overheating problem could be due to apps like “Clean Master” as it’s a third part app. But that was’t the case, cause when I’m downloading other apps like Facebook, Twitter, Intagram etc., the problem still continues to exist.
Also, I don’t think Facebook Messenger could be the problem, cause many of my family members are Samsung mobile users, who use Facebook Messenger without any problem.
When I tried searching the solution to the problem on Google, I found the phone overheating could be due to the following:

  1. Problem with the hardware.
  2. Bad internet signal.
  3. Problem with the battery.

I’m not sure what among the above is exactly the cause to my problem. I still have 2 months warranty left, so if the problem is with the hardware, I can have replaced for free.

Anxiously awaiting a favorable reply…

The problem may be due to a faulty battery or too many applications which are opened.

I agree with @dharmen2000. The too many apps open is the more likely scenario, IMHO. But, then, I’m so OCD about making sure that I completely “close” an app, when I’m done with it.

If you already have Clean Master and Battery Doctor on your phone, how often do you actively run/scan/close/clean with them? I do that about ten times a day, just to be sure that my phone is using as little CPU/RAM as possible.

Not sure how to test if the battery is at fault, but I’m sure Google can find that, for you.



@WolfShade I do it often after I’m done surfing the net, as well as clear the RAM space.

Hmm… then I’d guess it’s either a faulty battery as dharmen2000 suggests, or (if you have your phone in a protective case) the case may be retaining the heat.

If you can’t find a method of diagnosing the battery, I’d contact the vendor and ask.


@WolfShade Are you sure it’s not a hardware problem?

Every galaxy user I know has the overheating. I find it hard to believe it’s a universal hardware problem and noones pointed it out.

My S5 doesn’t overheat, even inside the Pelican case. Battery Doctor and Clean Master really help.

@rohanferns, as far as I can tell, it is not a hardware problem.



Every galaxy s3 user I know* (which WAS 6, but a few upgraded.)

My s5 doesn’t overheat either.

My S4 does overheat sometimes but FB is the one that causes it. I close it and then I wait two minutes… and then it is OK. That happens every week or so.

I don’t check FB at home. I only open FB if I’ve seen something really interesting and I can’t view properly on my phone (like some videos embbeded on a web page which annoyingly can’t be resized). The only reason I’m active in FB is because it keeps me entertained on my way home lol

Hi, i have a problem with my s3.

Yesterday, I just reboot/reset my Samsung s3 and it was completed. When I turned on my phone the letters SAMSUNG and the blue light is turned on but it’s already been an half hour and nothing is happening. The word Samsung and the blue light is still on and it’s starting to heat up. I was worried so I remove the battery, even though my phone was still on. I turned it on again and it’s still the same. What should I do??? Please help?

It may be doing an update. My S5 does that every once in a while. If it keeps happening, then it may not be an update, but an issue requiring vendor support.


I replaced the battery over two days ago, but alas the problem of overheating sill exists.

I request the expert members on this forum to please provide a permanent solution.
Would it help if I get the hardware or motherboard replaced?

Anxiously awaiting your reply…

We’re not experts on mobile phones, and that includes Samsung Galaxy. All phones overheat at some point, some more than others. In my particular case, my Galaxy S4 overheats when I’m using FB or some app that uses the network heavely. I close the application and the phone cools instantly. But that’s my experience

If you replace the hardware, you’d be better off buying a new phone.
