Screen burn possibly due to overclock

I got my Evo June 4 and rooted soon after. Its been overclocked to 1190 ondemand.
The phone gets pretty warm to hot with heavy use. I notice this heat towards the bottom half of the phone.
Then I noticed that on any light background, there is a small 0.5"x.25" area where the screen is noticably brighter. It's about 3/4 of the way down the screen & right in the middle. It is not noticable on dark backgrounds though.
I am wondering if anyone else has this issue and is it possible due to getting hot?

Nope... I'm at 1.15ghz on the performance profile.

how hot does it get?

LCDs cannot burn an image. They can retain an image, however that can be generally corrected with a moving image over time. What you have may be the light leak from the button LEDs. My dad has this phone and his has an issue similar to what you're describing.

I mean, if I'm playing tower raiders for a good twenty minutes, it will be hot to the touch on the lower half and with no venting, it just bakes itself

Do you have a profile to scale back the overclock when temps reach > 50C degrees?
I have seen my phone approach 47 while charging in the car, hot day, and streaming music and that was about as hot as I would want it to go.

Haha wow. I had mine @ 60C once. Then again it wasn't from running it, it got left in the sun on a pool deck for 2 hours

It's just light from the buttons. LCD's don't get burn-in. AMOLED is a different story, my Nexus has WICKED statusbar burn-in

I've also been overclocked since overclocking was available and I've never gotten anywhere near 50C.
Most I've gotten is 110F. How is it getting that hot?

LCD Burn
He's not talking about screen burn. He's referring to lcd smear which happens due to localized temperature and/or pressure changes in the lcd. Mine is doing it as well (my first one didn't), and the palm pre was notorious for it. There was an excellent explanation of it on precentral.net forums. It's only noticeable when the background is certain colors behind the pixels affected. Unlike the pre, however, this seems to be permanent.

I got mine on launch day as well
And I never did any modified kernels or overclocking and I had a similar bright spot that was most noticeable on the white htc bootscreen. I was rooted but it was a stock rom and so I took it in and showed them and demanded a replacement which I went in to pick up 2 days later. I bought it from radioshack and got the replacement from sprint about a week ago and now I have hardware revision 003

I suggest dont over clock your phone because your phone gets to hot and it causes too much radiation and you could die for having too much radiation
Sent from my HTC Evo 3G because there is no 4G here.

I have the same issue, from day one. So i don't think its an OC result.

New, but a refurb would probably be just as good if not better than new.

Please explain the 'refurbished being better than new' theory.

I have the same issue and its located in the exact spot you are describing. Ive only overclocked my evo for about an hour once, but this mark has been there since the beginning. Probably another error on HTC's end I suspect....
It's a Google i/o version of the phone. I actually managed to get Sprint to send me a new evo through customer service due to light leakage so I'm not really worrying.

Wasn't the Mogul notorious for this?

I have the exact same spot in the exact same place. I don't think its due to OC. Mine appears to be getting worse (much more noticeable). I'm prepping for an exchange myself.

Epic gets very hot when I use 3G or 4G

My epic gets very hot when I use 3G or 4G, It is hot to the touch and situated at the top of the phone near the camera.I have 4 bars and no signal problems whatsoever. Does anyone else have this.
Thanks

Yeah. It'll do that. Especially if you use the connection for extended periods of time. It's nothing to worry about.

Mine doesnt get hot like at all.
The only time is gets hot is if im charging while playing a game or charging while it on like leather furniture or cloth. Other wise those are the only incidents i have to see where it gets hot.

Anyone else have anything to share?
Thanks

Download an app like battery indicator or spare parts and tell us how hot it gets. These apps have a temperature indicator on them. See exactly how hot it gets. Mine only gets hot when it's charging and I'm running high CPU things on it but I've never felt it get hot like you described off the charger.

I just checked today it was 42 Degrees Celsius. What are you getting?

I just bought one of these phone. I have also had the issue with the phone getting hot while on 3g. Streaming audio it gets pretty hot on the top half of the phone. The battery doesnt get hot at all. If i use netflix, it get very hot on 3g but doesnt while on wifi. Could this just be an issue with the radio on the phone getting hot?

The processor is working harder to pull the data while on 3g and that is why its getting hot.. imo if its not getting above 115 degrees really nothing to worry about... just don't use it for hours on end while its that hot. Also flipping the phone onto the screen while its streaming seems to help with the temperature also...

[Q] Is your Galaxy Nexus overheating too?

The back of my phone is really heating up with only moderate use. Only a few minutes of youtube or angry birds will get the phone hot. The hot spot is only on the right side of the rear camera, or the backside of the front camera, however you wanna see it
Has anyone had the same problem?

My phone gets warm playing wind up knight. I haven't experienced hot yet.
Sent from my Galaxy Nexus using xda premium

when i've been using mine for a while and then make a call it is rather warm around the earpiece, dunno if thats normal or not.

Your thread title implies the phone is having a problem (ie. crashing, stuttering, FC) getting warm isn't really 'overheating' many mobile devices get pretty darn warm during intensive activities.
Are you experiencing a problem?

I just used my nexus as a wifi tether for my laptop for 3 hours, while charging off a usb cable and usually I get high temperatures usually when doing this with other phones, however nexus was cool to the touch after all this... haven't noticed much heat ever with this phone.... however I'm not a big gamer either.

Facing the front of the screen, the top right corner in an L shape seems to heat up quite a bit - from something medium intensive like web browsing.

No the title does not imply crashing of stuttering. If I did it would have the word 'crashing' or 'stuttering' in it.The title implies exactly what I'm getting. The phone overheat strongly in one spot , from very normal use. Not intensive tasks.
I haven't had FCs or anything like that so far. But it does get pretty hot. It is alarming if I may say.

I have a feeling there is something in that corner that is dissipating the heat. I have a battery temp monitor and when it was really hot in that corner, my battery temp was 40C (30C seems to be normal idle temp) - but the center of the phone where the actual battery is doesn't feel hot.
So I'm assuming the heat is drawn to that corner.
Another thing I noticed (comparing to my previous phone) is that even though it got hot, it cools fast as well.

I get the same issue as well. But it wasnt particularly alarming since my Captivate, Infuse, and Skyrocket did the exact same thing. I have used the captivate and infuse for a long time now. The captivate was purchasd on launch day last year and has been passed down to my girlfriend, infuse is still being used daily by me since launch day as well, and the skyrocket (least used phone) was JUST sold for the funds to get my new gnexus. All of these phones have the same issue. I just figured Samsung phones get warm but thats it.

My phone is fine. I don't even get warm unless playing a 3d game. Charging is unusually cool. And I haven't even felt warmth from heavy hspa use.
Sent from my Galaxy Nexus using xda premium

to be honest...mine does seem to be getting rather excessively warm at the top right on both the front and back side...it's around where the RAM chip is on the PCB or could be around the CPU (which is more central but *shrug*). I cant think it's normal since i've never had a warm ear when i've been making a call with any phone i've had before!

My GN can be "very" warm at the back where the rear camera is. By playing 720p/1080p video files. Heavy HW decoding I believe.

So there is something. Can't believe no tech news site reported this before. Giving how quickly everyone rushed out to point a flaw the GN.
Has anyone contacted any Samsung rep on twitter or something? Who do we raise our concerns to?

I'm wondering if i should get my phone returned as DOA (since i need to do that by monday) with the getting quite hot and sleep of death and random reboots :|
i havent owned a high end phone like this though, and it's personally my first android phone (other people in the household have had one that i've mucked about with) so i dont actually know what to expect from it really...

I watched a netflix movie over mhl. The nexus got fairly warm. Still no overheating issues or reboots for me.

There is nothing wrong with it....... LOL "overheating" denotes your phone is crashing,stuttering,melting,burning or warning you that its hot....ect. So far nobody in this thread has this issue sooooo..... If the device is functioning properly then its not "overheating" as your thread title suggests. You should have put....does your phone get warm? Yes, just like computer processors they must get rid of the heat somehow this one dissipates it in the back just like most other phones.

except...the front is getting rather warm too. Doing simple things. Is that normal? Probably not. And excess heat + displays = bad. Also rather uncomfortable when you're making a call...if people use phones for calls anymore

Getting hot

Anyone else's getting very hot. I already returned two rezounds for getting up to 150now my nex is up to 111 right now and all I was doing was playing around on Facebook. Most of the heat feels like it is on the top half of the phone and the screen gets extremely hot

Charging now wasn't then and yeah I keep brightness up otherwise the screen is way too grainy. You should be able to use your screens top levels without scolding your fingers lol just curious if this is a common thing or If I have to yet again get another phone

My phone heats up on the top part like yours but mainly when I use it while it charges or if I keep the screen awake for about 20-30+ min straight.
Edit: just like your laptop or TV or psp or any other electronic device lol

Not seen any issues on mine so far and it doesn't get as hot as my iPhone 4S when that is charging and/or using bluetooth for making calls.

yeh my phone gets quite warm also , crazy thing is when it gets warm im sure it affects the colour temp of the screen.

Mine gets hots quickly when I play Riptide a lot.

I noticed this too, but. I don't feel it since its just the top half and my hands are gripping the bottom half. I do feel it when I stick it in my pocket and my thigh gets really warm.

Mine heats up at the top back only when I'm using mobile data to do stuff. But I can use wifi all day with top brightness with no overheat. Stupid.

when I got my phone a few weeks ago (GSM 4.0.1) my phone easily warms up especially at the back near the camera area. After manually updating to 4.0.2, I really noticed it was gone. Now even I am watching youtube videos for more than 20-30mins my phone doesn't warm up even a bit unlike before i got it on stock 4.0.1 in which just turning on a wifi connection and gps warms the back of my nexus without running an app.

Define overheating. Because i think the phone does quite well for how much horsepower is under the hood. Mine gets warm doing this, that and the other. The only time i was seriously concerned was watching a netflix movie over mhl and really i was really only concerned about the battery temp than the phone. The phone and its components are a big step up from phones 3 years ago. People used to whine about phones getting warm when 3g heated them up and 3g was becoming the norm. Fast forward to today and there are more powerful components packed into less space, and less ventilated at that. If you dont like your phone warming up get a dumbphone and be done with it. I think the nexus and most other smartphones do quite well. And this was before i undervolted it. I can only imagine how many useless threads will pop up about heat when quad cores come out. Personally when i upgrade next, hopefully two years from now and not the annual phone i am accustomed to, i hope a dual core cpu and gpu at 28nm or less will be sufficient and be well within the thermal windows and limits for how powerful these pocket size devices have become and dramatically changed our social lives.
Crazy world, ay?

mine gets hot up top on my ear when I'm on a call. I found at least by switching to the new 4.0.3 radio and doing a combination of over clocking + under volting it doesn't get nearly as hot anymore.

I'm talking when my battery temp is 111° and the top of it feels much much hotter than that. I'm on 4.0.2 I understand the phones will get warm but they shouldn't from ten minutes of Facebook. If I was watching Netflix using my GPS and doing so over 4G then yeah scold my hand I get that but not frickin Facebook or internet browsing or anything like that. I really like the phone and ill be keeping it but apparently won't be playing many games lol

I use a SetCPU profile to peg back the processor to ~700mhz when the temp gets over 40c

Whoa, it's overheating? You might have a defective phone. Mine gets pretty hot but the heat hasn't led to any stability issues or damage like yours. (Note: It's not overheating if there's no damage, so I'm assuming by your text that your phone got damaged)

No not damaged. I leave it alone once it gets real hot. I've turn down my brightness to help prevent it a little. Def doesn't look as good lol

Left Side gets Heated

I was reading on the Note 8 the other day and started noticing that the left side of the tablet gets pretty warm/hot. Is it just me or does anyone else have this issue? The rest of the tablet remains cool- just the left side around the middle.

This issue already discussed before. It is quite normal for a device to get some heat. Anyway, I think there is a big difference between warm and hot. If your device really gets HOT, then it is a problem. My device gets warm as well as you described, but I wouldn't say it gets hot or uncomfortable to hold. I think the temperatures quite similar to my SGS3.

CPUs and GPUs put out heat. Batteries put out heat. The more intensive the activity (particularly watching video, gaming, internet use and GPS) the more heat will be generated. This is a fact with all tablets, and computers in general. I'd think it was strange if the device didn't get warm somewhere. Heat on the left side is completely normal, although not sure what component (CPU, battery, etc.) is located there.
Now its impossible to tell what OP means exactly by "warm" or "hot" as this are not quantitive in any way. It shouldn't get hot enough to be uncomfortable (or even hurt) to hold in any way. Excessive heat may be an indicator of a faulty battery or some other hardware defect. But usually not. And the device will shut itself down long before a temperature is reached, that will hurt anything (if that is what you are worried about).
There are ways for the system to tell you the temperature, but I think its only at one location (CPU?) which may not be the problem area. So measuring this way may have limted usefulness in real life.

That is the location of the cpu unit so I wouldn't worry about it unless it gets very disconcertingly hot.

Im using the Sansung OEM cover. Holding it in portrait mode, mine gets "warm" on the left side near the edge... but only when its in my pocket and its in sleep mode and wifi is turned off. Kinda fels like my BlackBerry when its polling for a tower, it gets real warm. I have a N5110 wifi no radio so trying to determine why the warm up.

Hey thanks for all your input guys. It's good to know I'm not the only one experiencing these problems. So far, I don't think it's bothering me to the point that I wish to call Samsung up for a replacement. It does get a bit warmer especially if I have the pen out and writing some notes. I do also understand it's more than likely that the cpu is located there but I've never had a warming problem w/ other smartphones and tablets I've had.
Either way, thanks for all the input!

I agree with you, my father's got an iPad mini and the gadget doesn't present warming problems and battery life is much better. Do you think all Note 8 devices present the same problem? I'm thinking seriously of replace mine for a brand new Note 8.0 but if it presents the same problem, I'll be wasting my time...
