I have had a Galaxy Note , and i was thinking not to get the 7.7 because of the same reason, it allways overheated and switched to powersaving mode, and everything slowed down, menu, page loading ect (it became hopelessly slow, embarrising!!). . .
I am a heavy internet browser, and this kills this tab, and this processor sadly I think ICS wont help either(thow in theory it should).
When scrolling on a browser (in Desktop mode)the cpu utilization is nearly always maximum, see with: Cooltool, also check it lock down to 800mhz when overheated, now its summer and this crap overheats after 5minutes, Cant believe none of you have complained!
Im going to sell this tab , soon as there will be an alternative! damm this overheating peice of . . .
I would really like to know what you do to make it overheat. I surf the web alot too but I never noticed any significant heat change. My Tab only gets really hot when I use photoshop touch or play ressource heavy games.
Could you explain what you exactly do when this happens? IE very much tabs open? Or sites with much flash content?
Maybe you have some ressource heavy app running in the background, I had a bunch of apps in the past that drained battery like mad even if I never started them, that led to very hot device too. But I never hat a shutdown because of that.
By the way if you are using your tab in an extremely hot environment, maybe set lower frequency for your cpu (needs root).

Yes flash heavy sites such as engadget, even not scrolling generates 60-70% cpu in 800mhz, and if i scroll for about 5 pages, you can see and feel the device has overheated. You can test this by setting setcpu onto performance mode and 1400mhz, and use : Cooltool from the market to monitor OSD your current CPU clock, and you'll notice it jumps down to 800mhz, despite setting it to performance! Maybe the next 7.7 will have a cooler cpu, better with architechure less nanometer .
i get that a lot!
no flash enable!
i'm forced to press Power for 5 sec and reboot

My device never freezes never shuts down only locks down the mhz to 800. But if you exit the browser and wait for it to cool down it goes up to 1400again when needed.
I dont know about the shut downs you guys are talking about.
I have found that most of the sites generate alot of cpu useage just sitting on them. I too have flash set to on demand and never start them unless it is a video i want to see . And also intalled Adfree too!

I haven't noticed something that bad with my TAB however indeed the few times I'm browsing the device indeed seems warmer... So I checked with telegraaph news site in the Netherland as an example; the page is quite big and there are couple non static object in page.
Using cool tool and monitoring CPU usage
Strock browser siting there having the view on a place where all is static yields about 95 # CPU usage...real bad indeed...
I also use OPERA and here the things are better at around #50-56% cpu usage...
I used to have CM9 on TAB 7.7 but it is currently not usable...So I try on TAB 8.9 with GALAXIAN SOUP ROM and Chrome beta... and got about 75# cpu uage on a page having only static object and where the pages is less static (moving objects etc) there it goes at #90 to 95%. So it seems Chrome vs Stock HC browser attempts some optimization here?
So ICS might help a bit but not that much indeed...
I'm really surprised about this high CPU usage on stock browser and Goolge stuff, not sure necessarily the HW is the culpit here, but rather software and optimization. I have IPAD 1 far less powerful and curious to see how it does there .....
So yea it is sad to see that... was not aware of it until now but I bet this is known in the Android community?
Same overheating problem here on my Tab 7.7's left middle side, and worse, battery drains so fast than usual.
This is my 3rd tab 7.7. My 2nd one had a faulty charging IC rendering my unit as useless, Service center said it needs board replacement!
Quo vadis, Samsung?
Hello. I have a Samsung Galaxy S4 octa (GT-i9500), i want to play Grand Theft Auto San Andreas on it. The thing is i was playing it before I updated my device. When my device was on 4.2.2, it was running really smooth. Now I updated it to 4.4.2 and installed on it, not it's not fluent. Every 3-4 seconds, it freezes for like half a second and continues from where it was. Now I tried lowering the graphics and also turning frame limiter on/off but none helped. Even on the lowerst quality, it still does the same thing. What can I do about it? Please help.
Thanks.
Hello pros of XDA forums!
I recently got a hold of my first Android device, the A500. It came with factory stock Honeycomb v3.0.1. Because the build-in system update no longer work, I flashed it to 4.4.4 OmniRom by IconiaHD from this thread http://forum.xda-developers.com/showthread.php?t=2705989.
Everything works great except when I watch Youtube 720p videos with the Youtube app, the video would lag very bad. It's not network lag, sound plays fine but the video just freezes then plays for a couple seconds then freezes again. It's the kind of lag you get when hardware is not fast enough or when there's too much software in the background eating up all the CPU cycles. But I checked background app CPU usage with Watchdog Task Manager and no app is hogging resources. I then tried to increase CPU frequency, change CPU governor, IO scheduler, nothing helped. CPU set to performance helped a tiny little bit but overall video still stutters too much.
Anyone else have this problem?
Also under Known Issues of the IconiaHD's thread, it says "-Default sound recorder app is included but the icon does not show up". Does anyone know how to make the app appear so I can use it?
WARNING WALL OF TEXT
This is a dirty trick to solve the overheating issue on our beloved K3 Note, at least it works for me.
My worst overheating issue on this phone was the phone went into shutdown mode when I was playing Ingress (hot day in a car without AC). I haven't test it on Ingress yet after I made the modification, but on Pokemon GO and Clash Royale, no more serious lag on Pokemon GO (didn't test on the evolution animation yet), no lag in Clash Royale and Ingress, and no overheating even when connected to power source (2.1A power bank in my test). The phone will still be a bit hot especially at the front speaker area, but so far it is not enough to trigger the overheating warning for me.
I take no responsibility in case your phone is damaged from using this method.
Steps:
1. Root is required.
2. Download any root file manager (ES File Explorer) for me. Go to /etc/.tp and rename thermal.conf into something else (eg: off.thermal.conf.off).
3. Install Kernel Adiutor from Play Store. Open Kernel Adiutor, go to CPU and change the CPU Maximum Frequency to 1560Mhz. Set the CPU Governor to Interactive. Open CPU Governor Tunables, set hispeed_freq to 1560000. Enable Apply on boot.
4. Reboot
I test this on Androium VUI 1 ROM by Matx13. My personal result is very promising in my nearly 24 hours test. The phone will be a bit slower due to 130Mhz reduction on CPU speed, but enough for gaming (at least for me). At least there's no more overheating warning.
If you are using external casing, lose the casing if you are gaming on K3 Note.
I hope this is useful.
Can anyone confirm it is truly working ?
Is it still stable and well-functioning ?
This overheating issue annoys to much !
Thanks you.
So I don't know when this started happening but almost every single game on my Galaxy S7 lags after about a minute of playing, like the frame rate will get cut down from 60fps to a choppy 30-50fps, and stay that way unless I exit to the home screen and back into the game or press the app switcher button for a second and go back into the game, then it jumps back to 60fps for a little bit and the lag goes away but it always comes back.
I have no idea what's causing this problem and I'm tempted to factory reset my phone to see if that fixes it because I've tried almost everything (disable game launcher and tools, disable the packages, game mode, high performance mode, delete cache, rebooting, etc.)
Does anyone else have this problem and could it be a certain app using resources in the background that's causing lag? I'm on the stock rom from at&t, no root and no bootloader unlocked, everything is pretty much vanilla.
Finally after months of trying to figure this out, I fixed it by pure luck.
Every Galaxy S7 user should do the following:
1. Download Game Tuner
2. Create a custom profile
3. Set FPS to 60
NOW ON TO THE MOST IMPORTANT STEP!
4. Set HW Performance to +4
HW Performance affects the stupid throttling that games seem to do that prevents smooth 60fps in an effort to preserve battery life and keep heat down I'm guessing. Setting it to +4 fixed all the lag I was getting in every single game.
