I can't see your phone so I don't know what is exactly going on, but if you type into Google any smartphone name and word "overheating" you will see dozens of threads and articles. People are just overreacting, smartphones are getting warm it's just their nature, plenty of processing power etc. If yours is getting too hot maybe it's some app working in background.

My phone gets very hot on top of screen, near speaker

My phone is also overheating very quickly now. It started after i rooted the phone and installed some root apps like greenify and clean master. I have now disabled those apps to see if it helps.
Anyhow, it's not a big deal. It won't burn up so what is all the fuss about?

I have the same thing, the same spot as you mention. On samsung stock rom its really worse!, but on cm its decent. however, my pone always turns off when testing antutu at stock max cpu speed...
I can only go to 1674mhz. any higher and it will instant shutdown on antutu

hi, i'm from singapore
and im using the i9505 variant of the S4 and i'm having the same issue about the heat on the top half of the phone
it heats up so bad i cant touch the top half of the phone at all
Is this caused by the 4.2.2 update like what everyone says?

My view/experience with i9505 on (over)heating. I direct this at Samsung ...
Dear Samsung,
Please can you move the WiFi Power Save Mode Toggle from the Service Menu and place it in the standard Settings Menus. Also make this setting persistent between boots.
On certain AP hardware and/or configurations, the Power Save Mode does no saving at all, in fact in my experience it just causes a huge mess. The culprit is spotty/erratic WiFi connectivity which causes all the background sync/update tasks to go in retry loop heaven (with wakelocks galore). These background tasks in retry loops hammer the processor continuously such that it start heating up (& draining more battery than normal).
So please implement this small change so that it can save many a lot of headaches.
Thanks.

Heating is a big deal for me. S4 is a lot more hotter then my former S3, and not because of the CPU. For me it's because of the modem. Root might be related also (I had my doubts on this) ... some apps keeping the 3G up more then needed, but I don't want to speculate more ...
PS: there are others "overheating" posts , a lot of them.

Same issue here (thread here), my brother has the same model and we tryed use same apps on both S4's, his S4 does not heat but mine does. so something wrong with my S4

i think the rom is causing all the overheating issue.
when i used stock, it would heat up that i can't touch it
now using phoenix rom 2.0 for 9500, and only get a slight warmth

My first smart phone was an Galaxy S2, and it got hot, i had two replacements they were the same, i then realized smart phones with powerful cpu/gpu`s just get hot when they work hard, i had had a few smartphones since the S2 from a few different manufactures and they all get hot, now i have an htc one, and it gets hot so it`s totally normal.
what i have realized with android is that you can get a faulty app or system process that really kills the cpu/gpu for no reason and they need to be shutdown/killed.
So i started using an app called watchdog, just change the settings to monitor system processes as well.

my friend is using i9505 as well and his doesnt heat up like mine does
when i bring it over to Samsung, they said 'its normal'
and they said nothing can be done about it

My phone was overheating as well, and I found out the culprit was media server. It got confused with some old thumbnails I had on my old SD card (from my galaxy S3), I had thousands of pictures there, so I guess it was constantly scanning it.
So delete all the thumbnails, (there's a folder .thumbnails in DCIM I believe) or even better yet, if you can, format your external SD card, and copy the files you need on it again. then mediaserver will work hard one more time and that's it.
Alternatively, you can download Rescan Media ROOT, and disable the media scanner, and enable it when you need it (but that's not desirable for me, I'm always updating my media, so I prefer it being automatic, depends on you usage)

I flashed Cyanogenmod yesterday and all my problems with the device are solved. No lag, no overheating and much better batterylife.

The S4 does heat up quite often, what version you using? I would recommend to use KT kernel to underclock and undervolt so it doesn't heat up as much

Ow i like the heating part on my SG4 its really helpfull if ill ever go to Antarctic
Its a life companion.

[HELP] Critical CPU glitch

Model: SM-N9005
Country: Unknown
Version: Android 4.3
Product Code: XSI
PDA: N9005XXUBMJ1 (previously N9005XXUBMI7)
CSC: N9005OJVBMI2
MODEM: N9005XXUBMJ1 (previously N9005XXUBMI6)
There is CPU-related glitch that I've experienced since I've bought the phone on the 25th of Sept.The bug existed in the out-of-the-box firmware as well as in the new MJ1 firmware. The reason I didn't bring this to light and seek advice earlier was because I wanted to wait for the first firmware update (which came) hoping that it would be fixed (which it wasn't).
Description of the glitch: The processor would go on a state where it would ONLY start utilizing CPU1,CPU2 and CPU3&4 would remain "offline" no matter how much stress is placed on the phone.
Symptoms: I can clearly see the phone is only utilizing two cores with any CPU monitor from the market (see screenshots below); phone gets hot much easier under heavy stress as all stress is being put on two cores instead of shared between four; benchmark scores drop by half (example: quadrant score is ~21,000-22,000 , it drops to ~12,000-13,000 once the processer goes into that state); some demanding games start to exhibit lag and choppiness.
How frequently does the processor go into this state: It sometimes happen once in a day. Sometimes it happens once in 2-3 days. As far as I know, it remains in this state unless and until I reboot the phone. I don't know how it's triggered.
How to temporarily resolve the problem: The only fix I came up with is to reboot the phone, whereby the issue disappears immediately once the phone boots up again (that is, until it comes back again in a couple of days).
Is the problem software related? Does the problem exist in other Note 3 firmware?: I'm betting it is a firmware rather than a hardware related issue, otherwise the problem would not go away with a simple reboot. I don't know if the issue exists in firmware other than mine. It's probably not wide-spread, since I haven't seen it reported by anyone else. This is the reason I created this thread, to bring awareness to other people as well as to hopefully get help from someone more knowledgeable about this kind of thing on how to go about to get rid of this issue (the temporary fix is easy enough, but I don't want to bother with rebooting my phone every other day for one year.)
Could some root application be causing this?: Nope. The issue occurred before rooting or modifying the phone in any way, it's still present now that I have rooted it.
Other things to note, power saving is OFF always. I never turn it on. I don't have any application that could restrict, under-clock or otherwise modify how the phone or processor operate in any way.
I have attached screenshots below of when the processor is operating normally, and when the processor goes into the utilizing-only-two-cores state.
Applications used: Stability tester [to put stress on the processor], System Monitor [..to monitor the CPU, obviously]

Do you have to leave the monitors running many hours to catch this issue or does it occur quickly after reboot?

It happens so randomly and sporadically. I can go for 3 straight days without reboot and without the problem happening. I don't keep flying cpu monitors active all the time, I just opened them for the sake of taking the screen shots.

I had just noticed this on my exynos note 3 today, at least it may have been the same issue im not sure yet. For the second half of the day the touchwiz interface and several apps were noticeably laggy, not a huge deal but compared to what it should be. It was working at about the speed you expect from a midrange phone. Nothing special was running, I cleared all apps from memory but it made no difference. I restarted and it has gone, but if it happens again i will be sure to check how many/which cpu cores are running. I have rooted it but no other modifications.
Come to think of it chrome was lagging like a ***** all of a sudden the other night too... I was tired and went to bed without investigating further though. Perhaps that was the same thing as today, which could be the same thing you have...

[Q] Is samsung s4 9500 worth a buy admist heating & battery issues?

Hi,
I'm thinking of purchasing Samsung galaxy S4 I9500 (black edition). I've seen some users struggling with it's battery and heating issues.
are all devices affected with this issue?
Can a custom ROM solve the heating and batter problem? if yes, which one is the best?
Please advice.

Im using i9500 with no problems
I cant say for stock firmware but on custom rom heating and low battery life problems are nonexistent. Heating occurs a little while playing cpu and internet intensive games, but nothing you would not expect. Battery holds easily through the day or even two of you will not play or browse much. About roms- currently I would recommend ozcan rom if you want to stay on 4.4 or barebones 5.0.1 android. Both are great for speed battery and features.

I'll choose i9505 instead, Qualcomm rather than Exynos, much better thermal and battery & 4G also
sadly when I bought the phone only i9500 was available and I didn't discover that till when I finished every thing and entered my car

[SOLVED] Normal 5433 temps? Overheating (75C+)!!

Hi there,
I'm getting worried as this Exynos CPU gets warm, really warm. Am afraid some component will get damaged, 75C-77C and raising! while streaming mp3 and playing a 2D game, I've checked with CPU-Z every time. This usage shouldn't be a problem. I was doing the same setup three years ago with a Galaxy S2 i9100 with no overheating issues (50C max), what the HELL?
What's the normal functioning temp for this processor? What's the damaging threshold for it?
SM-N910C with BOC3 Lollipop, no root, 100% stock. Really thinking of downgrading to KK now

Try latest BOE3.

I'm on BOC3 and haven't experienced any overheating.

@Kinsman-UK - I can assure you that if you use Kingdom Rush (free in the Play Store) for more than 15 minutes your temps will skyrocket. Also, if you stream music (more usual) or data at the same time by WiFi you'll get a perfectly capable toaster. I did notice the thermal changes with the Smart Cover between the phone and my fingers.
@megatooth Upgrading to BOE3 can be a possibility, but I presume it'll be the same, no real changes there. I'm charging the phone and about to do the downgrade. Fingers crossed.

If anyone wants to replicate it, please install Kingdom Rush from the Play Store (free game) and stream some music at the same time. Never had such high temperatures in my android life, ever.
EDIT: megatooth was right and I was wrong, presuming tends to be wrong. It works, kids. Updated to BOE3 and got 40C after 30 minutes of playing and streaming. If anyone has the same problem, try updating.

Heating up | Exynos S20

Hi all,
I got my S20 a couple days back and never since that day have I not seen my phone heat up every now and then.
Heavy multi-tasking ; this thing starts to warm up which is normal but what is not normal is how excessively hot this device get when using the camera for a little over 5 minutes , whether it is recording videos or clicking pictures, this device becomes unreasonably hot.
Playing a little bit of game on highest settings for a couple of minutes shouldn't be causing as much heat as the S20 ends up generating.
I am skeptical for the logetivity of this device if this heating up keeps up on such trivial tasks.
Not sure, but has anyone before ever experience this kind of problem and has seen the OEM actually fix it with mere software updates?:fingers-crossed:
Let's discuss the status of each of our devices and figure if only a bunch of us have the devices which are behaving like this or is it happening with all of our phones?
SD S20 owners can also pitch in for comparison.:good:
Thank you.:laugh:

Yes I'm also experiencing same thing. Even watching a 3-4 minute video on YouTube makes the phone feel warm. Camera heats up the phone very quickly.
Hope Samsung solves the issue.

Same problem on camera it heats up rilly fast,not seeing that in you tube though..

Same here...or even worse. 5 mins on facebook/twitter and then the device becomes obviously warm.
Same thing happens when doing wireless charging. It still gets warm quite quickly even when fast wireless charging is disabled.

Exynos S20 exynos 990
Same problem. So I went to Samsung Service center and told them the problem regarding this overheating issue. What they are telling me is that 41.8 degrees(what they have read from my device using a thermal scanner) is normal (I don't think so as 42 degrees for trivial task is absurd) also they inform me that they will reinstall the operating system once again and check whether the problem still persists, if yes replacement will be done by giving us one certificate that we can take it to the shop where we have bought the phone and get a new s20 (what a lengthy process).

New Software updates
Since I wrote this post, there have been two updates pushed by samsung.
None of them made any dent to the slew of problems that this phone has been having.
I tested antutu score, I know they are not the real test for day to day usage but these scores have actually dropped since latest update.
The camera albeit is better at focusing , I can testify to that as I made two videos before and after the updates and I can see some difference but the heating is still going on like crazy.
Now I think, Samsung should have added a heat vapor chamber in the phone to manage this hot garbage.
Very disappointed to have payed so much and not even get the performance as good as the last year's SD devices.

Facing the same issue. I just want to know how can I get is replaced.

Samething on Exynos. When it hits 40c, it automatically switches to 60hz and get back when it cools down. Exynos was never good.
But one thing I can say for sure if you are worry about longevity. Never user your phone while it is charging. One thing is using your phone hot while discharging. Another thing is using it while charging and it will definitely impact battery life long term speaking.
I would disable fast charging too.

Same here! And if you have like 30-35% battery and your phone begins to heat up, say goodbye to 120hz, I think it throttles so hard that the performance can't go beyond 60.

It is really very very disappointing .It gets up so hot just using the device continues for 30 min. Once the temp cross 40+ it switches to 60hz. hahahah for this we have to pay a premium price.
Have already started to have 2nd thoughts for next galaxy devices with exynos. really really very annoying to use this phone these day in hot summers.
I hope to get it fixed soon. if not probably iam goning to quit this phone. very disappointed.

Display turns into yellow
Same problem here with ultra exynos after watching serval videos and using camera for 10 to 15 mins. At low brightness display turns yellowish because of heat and screen turns into 60 hz automatically. Has anyone noticed this yellowish problem?

Same issue
Same problem here guys, I am very frustrated.
First of all why make two variants, one with snapdragon an other with exynos?
Why this discrimination?
Secondly why should I pay for a flagship and get a less than flagship experience?
I hope it is partly software fixable.
I am so gonna be very unpleasant and persistent at support. Greece here and bought s20 two days ago

It goes back to the early 90's when Samsung made a trade deal with Qualcomm. As a result of the trade deal, Samsung were allowed to use Qualcomms products but only in the markets where Samsung's products didn't compete directly with Qualcomms i.e the USA.
Nobody held a gun to your head when you bought the device. You could've just done a simple Google search and found a way to import the SD variant. Samsung aren't discriminating - it's called business.
If you dont like the Exynos variant, the OnePlus 8 is being announced on the 14th - that'll surely have the SD865.

It sucks, the only software solution I can see is throttling TBH.
Honestly thinking about cutting my losses on my S20+

Least expected from a flagship
I have a S20 and it heats up to that level that with a cover also it gets uncomfortable to hold. And this observation is with not any heavy use, very routine use like checking Gmail, watching Youtube, browsing Instagram.
I sold my one plus 5t and got this phone, very disappointed, should have waited and bought a one plus only. Samsung, if you are hearing me please fix this - if it's a hardware issue, please recall and provide a replacement, if it's a software issue please fix. But stop asking customers to go to service centres as it is not a specific problem to any phone. Most if not all exynos customers are facing it.

We been really ****ed over by samdong with latest updates the charging has gone from 1 hr to charge from 0 to 100 too 80 mins and only reason i can think of is because of the overheating that exynos is suffering so we pay nearly 1400 notes for this piece of **** and its getting worse on every update **** you samdong
