S2 gets hot very hot

astonred · Jul 2, 2011

My S2 gets very hot around the rear camera area (near sim card) and top left front of the screen. it seems to be worse when the wi-fi has been on for half hour or so. Has anyone else experienced this?

There are lots (and I mean LOTS) of threads about this.

If you do a search before posting, you will find some useful information and this issue is one of the most talked about here.

I burnt my ear yesterday. Very worrying.

I have had three SG2 units and while I have felt the phone get warm, I would never call it hot, certainly not hot enough to burn my ear!

During intensive use of the processor the phone will warm up as this is it's only way to dissipate heat. I run my WiFi 24/7 so it must be doing something with the WiFi as mine is not even warm. The transmitter/radio for the phone can also warm your device up.

There have been so many threads on the SG2 getting hot that there may be more to this but not on the three units I have used.

I bought the tough case today

My phone acted very weirdly this evening. It switched itself off (i was sending a text message at the time) and then wouldn't switch back on for quite a while. When it eventually came on it was acting very erratically. Sluggish, unresponsive, the keyboard wouldn't pop up, screens closing themselves. I restarted it again but the same problem. The top corner was getting very hot and when i checked the task manager the ram was going from very low use to very high.

It's never done that before and it came out of nowhere.

My phone cooled down once I took it out of the case. I wonder if its the case that allows it to get so hot.

Perhaps that's why the Genuine Samsung Galaxy SII cases are vented.

i do believe it is a heat issue. iphone also shuts down due to extreme heat remember the infamous messages saying too hot to operate?

have you guys been using it outside in this summer heat? like by the pool or anywhere that it is exposed to direct sunlight in 90+ degree weather? or left in the car with windows up for over 20 minutes.

mine gets hot under these conditions and everything runs sluggish until i power off let it cool down and reboot. by sluggish i mean not smooth scrolling of web pages and home screens

The only time I have noticed my SGS2 getting warm is when doing intense gaming and having it plugged in, charging at the same time. It will then (kind of understandably) get warm - but not hot!
During normal use, WiFi on constantly, updates in background and so on, it doesn't get warm at all. I have it in a rubbery protective case.

I wonder why Samsung has no heat sensors on the cpu for the GS2, I really would love to know more details about the heat it produces...

Thinner is not always better when there are no fans present in these devices. The thinner they are the hotter they can get.

I hope they get this issue fixed before the us release.
