-Do you live in hot areas?
-Do you use overclocking?
-Do you play alot HD games ?
-Do you see any side effects of heat as reboots or freezes etc?
-Are their many background processes that case overheat?
-As i know the heat protection is built in the Omap architecture (the processor) so do not worry, if it overheat, the tab will reboot
-May be try custom rom as cm10 from www.teamhacksung.org it does not have much background processes as it does not have the bloatware of stock roms so may not cause more cpu cycles so no overheat
-Try setcpu may be have temp monitoring

yes i play hd game a lot.and about background process i kill them all...
And till now my tab freezed/rebooted one time since i bought it(and i do not think it was due to overheating).
I know it get hot while playing hd games but it get warm even with little internet browsing...

Regarding killing background processes, they may return again after killing them immediately, in fact may be the task killer is causing this overheat ( kill load kill load etc) so remove or freeze apps that cause this background processes or better use custom rom or stock debloated rom

no i never use task killers(they sucks...)
i do not have any unnecessary service in app manager...

It's normal it overheating, and it's normal because it hasn't any type of holes for the air in the rear plastic cover
The first time I see it was 41°C with stock ROM and some basic game and i was surprised, but now, with cm10 is the same (37-40°C) I think it's normal after some weeks of tests
My friend have a galaxy S2 and it go over 37°C and sometimes the rear metal chassis for the photocamera is like a heatsink

More RAM consumed in ICS

Ever since I upgraded to ICS, RAM consumption is high in my atrix2. It used to have free RAM around 300 to 350 MB but now in ICS the fee RAM is always around 150 to 200 MB.
I am having same apps which I used to have on GB. Nothing changed on my phone. Can anybody advice me whats wrong with my phone?
Ex. Games like Temple Run are little bit sluggish in ICS whereas it was running smoothly in GB even though I had some apps in the background. Now in ICS it is sluggish even though there no other apps running in the background.

Android has its own task manager, which is quite sufficient. What people don't seem to understand about RAM, is that it is meant to be used, not the other way around. Android, like Mac OS and Ubuntu, wants to use all the RAM it can, because that's how it was designed to work. There are settings (in Android we call them "minfree" settings) to tell the system how much RAM to leave free and available, but the rest is designed to fill up as fast as possible and stay that way.
Android can manage memory rather well (and the settings are still there to tweak if you just have to touch stuff) and having up to 300 percent more RAM makes a huge difference. There will be a few times where killing off a handful of tasks will speed things up, but overall you'll get the best performance out of your phone or tablet if you stop worrying about it and let Android be Android. If you need to live on the edge (and I know a lot of you guys do) root and hack your phone with some amazing custom ROM that has everything tweaked and allows you to travel forward in time -- I'm right there with ya, 'cause it's fun as hell.
But don't worry about how many apps are running on your phone, or about using widgets that tell you these things, because it just doesn't matter anymore.

Long press home button, it will appear. Swipe to close apps.

Try with debugging mode enabled along with force GPU rendering from settings...

Task managers/killers are completely useless in android.The only use of task killers is when a rogue app keeps running in background consuming lots of CPU cycles.
After the ics update my phone too was a bit slow but then I factory reset it & then wiped the cache partition. I don't know what did the trick but it works great now.

Go to development, background applications, at most 4.

Awful screen.

1. less space on device memory , bloatsss
2. phone rebooting , happened 3 times while opening camera app
3. chrome eating lot of ram (500mb-800 mb)
4. with no apps opened, phone is eating around 1.09 gb ram.
5. its getting hot!

For me, the biggest negative is that the phone is not fast enough comparing to S3. Although, it might be touch wiz problem than hardware, because Nexus 10 feels much fluid and smooth.
Basically, I did expect a better performance.

Is a fault from Samsung that an external app (Chrome) uses a lot of RAM? NO.

Maybe because Chrome doesn't use a fixed MB, it uses a % of RAM. More ram more %.

it has a lot of features and a 1080p screen (yes the 1080 has more than twice the pixels of 720 that it needs to use memory for the GPU), it needs to use up some extra ram to run smoothly. imagine how slow it would be if it used 550mb and kept swapping it out
furthermore ive got a droid 3 with 512mb of ram... even with a custom rom with zero bloat this thing had like 50-100mb left to run apps... imagine how disappointed i am with it -_-

this isnt a legit complaint because its the fastest phone in the world. when i build a computer i expect some of the parts to sometimes run warm. in fact, my 7970 runs around 60 celsius under full load. the latest greatest technology is expected to get a little warm lol...
besides who ISNT going to use this thing as a hand warmer during the winter? lol

I too experience phone restarts when entering the camera app. Battery drains on average 10% every hour ( or more ) on medium use. Reached 50C degrees battery temp when browsing app, it got very uncomfortable to hold in the hand.

Yeap, I disabled all of them.
Still, when routinely switching between camera -> gallery -> email -> back to camera the transition between windows is very slow. And it's not because of animation, but probably because the phone needs to restore the state of a next app and it takes ages.
The phone is ok, but I expected more from 2013's hardware.

My phone never restarted itself, camera has crashed 2 times in 3 weeks, I don't have a problem with overheating, even if I use it all day (batterry draining is normal for a quadcore with 1080 screen... it lasts high use about 5-6 hours )

I have had 2 phantom "switch offs", first thought the battery was empty so put it on to charge, second time I tried to switch it on and the battery came up as 90% full.
No idea why it switched off - it was in my pocket.

Improperly perly calibrated amoled screens is the biggest flaw here

for me the most negatieve still is the battery, for it's size it's not lasting very long even with the AMOLED screen.
It's a little better with Cyanogenmod 10.1 installed.
Other then that for me this is perfect.

Why are the HTC fanboys replying here? Anyway, the negatives for me are the 9gb free and the stutter sometimes in tw. Great phone nevertheless

how to overclock s2 plus

hi every one could u please provide on how to overclock processor speed ? i have installed the kernel for it but after overclocking to 1300 the device frozen a bit it became slower than before please help

i think your question shouldn't be, "how to overclock", cause apparently you have already overclocked =="
your question should be "overclocking problems"
about your problem, i prefer you to set the performance down to 1.2 again, overclocking actually harms your hardware and is usually dangerous.
If you really want to overclock your phone, with 1.3GHZ, restore back to your stock kernel, and wipe cache, flash, wipe cache again, then reboot, i think this should help

1.2 is more than just fine for me on S2+.
Never had any lag or spike issue when multitasking.

sometimes the device freezes when overloaded with some operations but after overclocking it frozen more than before

I underclock it to 800mhz and it works fine, no lags. A typical daily usage for me: texts, whatsapp, emails (3 accounts synced), Neutron music player (which is said to require 1K mhz), browsing, instagram, occasional youtube, rss feeds.
But then again, I don't play games or watch videos/movies on it. Maybe this is what's causing lags and freezes for you?

I've tried for a day when I first flashed that kernel. Decided that the increased battery drain wasn't worth it.
What about apps, how many do you have? Also, widgets? Should check on them, could be the case of too many of them constantly running in the background.
Edit: Ah, just thought of this. What about the cpu governor and i/o scheduler that you're using

I use Viber, whatsapp, Email, facebook 24x7 and they keep running in thd back ground. Along with that I also play all the heavy big games like Real Racing 3, Fifa 12, Modern Combat 4 etc. I run all those games from my Ext SD card. Never faced any lag issue. I believe the specs of this phone are awesome and you don't really need to over clock or under clock it. Never freezes for me.

Seriously mate? It's so simple. Just set your desired frequency with the app.
And choose the governor e.g smartassv2, ondemandx, interactivd, etc. But avoid powersave and conservative since you don't want lags and choppy performance. Here's a guide to cpu governors: http://forum.xda-developers.com/showthread.php?t=2017715

Thanks a lot brother may be i didn't explain it very well i have set the kernel and the frequency which is 1300 ondemand but apparently the device started to get slower than before overclocking that way i thought i might be ruining the phone by doing such a thing and it didn't get any better

Do not overclock your device above 1,5 GHz!

lg g4 warms easily

So I have had this for about two days well the first day it got really hot around the camera an topper screen portion so hot holding just was a no an it was just doing normal task no apps installed just browsing so I factory reset it an that helped but not completely
So I then rooted to see if I could change kernel settings well it looks like my cores are almost always running at max speed so I downloaded kernel auditor to change setting an that still always want to go to maximum clock speed so I so I lowered it an it was still just at maximum 90% of the time So I disabled some cores bringing cpu temp down to around 94/96 degrees Fahrenheit is this normal or is it just me
Sorry for scrub questions I only had a s4 before this which was much less complicated
Thanks in advance sorry if I was confusing

Maybe there are some app running in background..try checking the usage manager, ..using bloatware tool also helping it to cool down

For me it was a circle case widget which was causing it to heat up. I used CPU monitor and found it. Closed that and it is fine since.

I also have problems as above and unresolved

I've been playing with kernel settings for a week now
so far i've noticed something regarding battery life (SOT) and its temperature
If i set big cpu to ondemand and LITTLE to interactive(default) the battery life stays much longer but the phone feel hot..
then if i set big to interactive and LITTLE to ondemand, the phone itself doesn't heat much but the battery life became poor..
and if you noticed, big cpu seldoms reach more than 384mhz..that's most of the time it stays in lowest of it frequency table
Maybe we can experimenting it together and discuss about it here
