Super noob here. brand newe to all things flash Rom and what not. This HD2 will be my first phone purchased for the purpose of modding however...
After doing a search for the words heat and hot I was not able to find much, and the wiki is down
So my first post is has anyone ran into the isse of the LED blinking green and orange and slow to no charge while plugged into the wall? To the point where it no longer charges?
I work in tech support and ive never seen anything like it outside of my gateway laptop.
I was running the stock ROM no mods yet outside of the Android mod that is being developed. i have master reset the thing easliy 10+ times in the few days ive had it though im not aware of constant reseting having a negative effect.
Basically on my way home while sitting in my console in the car I went to use it and noticed it was warm past comfortable warm. I had not used it for extended periods like hours of browsing wifi calls or using the phone hard.
I went to charge it 20 min later and it got really hot again after only being on the charger for 15-20 min and had only charged up to %15 from %13.
Took out everything let it sit overnight same thing the next day, tried a new battery and charger ( even though the battery was barely warm it is hot all along the bottom half on the back and going up the sides) and still had the same problem taking hour or 2 to charge 2-5 % and staying very hot with no use.
Im at a loss as to what to think any ideas?

Heat will cause what you are seeing, but also check and make sure that one of your battery pins is not bent, seems to be a common problem ..
Also have seen a few people that their battery was just bad , and they had to get a new one shipped in .....

Sure cant make any promises but Ill be happy to answer any question I can. I work in Teir 3 PDA support so all of my knowledge is tech based. Ill look up the task29 stuff Im not too familiar with that.
since you have already tried a different battery, and if the pins aren't bent, then its likely to be the phones charging circuits. get it warranty replaced.

I checked and didnt see it any bent pins they spring out just fine when removing the battery and apon inspection seem to be fine. One of the 1st things was for me to try a battery in hopes that it was that simple but to no avail
More information for those that care. The battery has been out now for a full 24 along with the sim.
I got home today and put the battery back in no sim memory card stil in. After being on for 8 min the back is far beyond warm.
The memory card is not recognized and I am certain it was before. This is getting weirder and weirder.
I wonder if it has anything to do with me trying to run the android mod off of a 2GB card that im sure was a class 2 and below, then master resetting it and going back to the 16GB that came with it?
More to come as i try new things.
Now the high temperatures in Austria cause the same problems on my HD2 when navigating in my car. HD2 after 2-5 minutes blinks orange-green (no loading) and after maximum 10-15 minutes crashes and at home too (my little office room has no AC, is in direct sunlight and room temp is over 30°C.
Unfortunately I have to rely on phone, email and office-functions and on navi-function for my upcoming vacation. No solution to place the HD2 in AC-stream in my car with this stupid original HTC-Car-Navi-Holder, in the office I have to put it in the fridge before to get it recharged.
When driving in the heat of noon I don´t even have to switch it on, just mounting into the loading-cradle is enough to make the HD2 crash after 10-15 minutes, only 3G on, nothing else (no BT, WiFi, HSPA, no app running etc.)
Until now I was quite satisfied with the HD2, had no crashes or malfunctions so far, but now I am really fed up with this piece of sh.. and I don´t think there will be a hardware or software-solution (except swichting it off) since the HD2 is malconstructed. And it IS correlated with ambient temps since it started to happen only when ambient temp is higher than 30 °C. When I am in a AC-room everything woks normal again.
i think i figured it out! i took out the sd and used the phone for 20 min or so. the heat gradually went away and its no longer getting hot. i am currently posting from the hd2 with a standard 2gb card inserted and will test my 8 and 16gnarled card today.
there is an issue with certain sd cards not being "officially supported"....
I read a post on here earlier from somebody saying that their 16gb card was causing their battery to drain fully in a matter of hours because audio manager was constantly working through numerous gb's of music on the card.........
may be completely unrelated to your problem but since you mentioned the card I thought Id chip that in..........
Hope you find a solution.....
I've had my note for almost two weeks now. This afternoon, I was using it as I always do, mostly mail, some web stuff and music - thus no extended gaming, etc to overheat the GPU.
I put it in my pocket, removed it several minutes later and it was completely dead - and I couldn't even turn it back on. It wasn't banged around or anything, and there was at least 50% charge in the battery. I opened the back, removed and replaced the battery. Still nothing. I tried again about 20 minutes later, and it powered up as normal. And it has been since.
Is this weirdness that happens occasionally to current gen android phones? Anyone else have similar issues? Should I try to exchange it?

thats odd. is it stock? if not, you should list everything you did to the phone. If you had it overclocked, maybe it overheated and shut down so as not to fry the chips?
Yeah, all's still stock. I've not even rooted yet.
Same thing happened to me with a skyrocket that I had. Except I did have it rooted running sky ics rom. And I had it plugged into the charger. So...maybe not quite the same thing...sorry. lol
I just went to the store and swapped it out for a new one. No questions asked within 30 days.

my note did the exact same thing yesterday or day befor,, i keep it in my locker at work , any how looked at it had over 50% battery life and when i came back a few hours later , it was dead , i got it to come on but battery was way way down , no life ,, dont know what the deal was ,, but has been running fine now.

Just happend to me, after testing out the mhl adapter at my parents place i restarted the phone. Then once all was booted up i put it to sleep to make the drive home only 15 min away i did notice the the phone was hot in my pocket but screen wasnt on. Pulled out my phone and it didnt turn on. I pluged in the the usb and it powered up normal.
Well its a new toy, they will have bugs and they will fix them. So far so good. I did get the juice defender app, seams to be.working.out.great went all day and still had 75% power when I got home.

My phone does get warm from time to time (on the back right below the camera lens), though I didn't notice it before the crash. Is this heat normal?
Only thing i did have is a random reboot once...thats about it.
Galaxy Note
My only odd experience is after unplayable Asphalt 6HD for a little while, and phone does get warm. After I close the game I get nothing. Blank screen and take a few minutes to come back to life and when it does it as if it went through a soft reboot.

UPDATE - problem has not gone away. It seems to be (at least partially) related to a malformed battery contact. Exchanging for a new one tomorrow.
I'm a light user throughout the day. Charged my phone to 100% before I left for work today. On my way home, I used my phone a lot. I visited websites that had a lot of content. I was pinching and zooming and the phone crashed/restarted on me. Same thing happen 10 minutes later. I was using the phone for about 20 minutes non stop prior to this to happening. The phone was in the upper 50s (56%-59%). The phone was getting noticeably warm on the back cover, but not to point where it was burning hot.
This doesn't happen to me during my lunch when I use the phone non-stop for a full hour. My phone is stock, not rooted. Had for about 1 1/2 week now.
Ok. So I was at work and at the end of my shift I went to unlock my phone and nothing happeneD. I had to hold the power buttllon for like 10 seconds to get the boot screen up. Does anyone else have this problem? I'm on saurom rc4

This sounds similar to what happened to me yesterday. Was heading to dinner, before I finished getting ready I had my phone start navigating to the restaurant and put it in my pocket. When I got in the car the screen wouldn't wake up from sleep until I pulled the battery and turned the phone back on.

That's what happens to mine except just holding the power button a couple times will reboot it. The n7000 group has the same issues I discovered after a quick google

Mine did that too last night (saturday march 24th) I am wondering if there was an update going on because when It finally turned on (after much panic) a few programs had updated I should mention im on stock rom with no root
Mine has been doing this too. It was fine for 3 weeks, then all of a sudden it started. For me, it will happen very frequently if I use the on demand or lagfree governors (haven't tried others though). If I use smartassv2 it has only happened once in ~2 weeks. In contrast, with on demand, even with a min of 384, it happens within 10-15 locks every time now. Crazy because I ran on demand with 192 min for ~3 weeks without a single hiccup, but now it can't go 10 minutes without the sleep of death if I use those same settings. FWIW I'm on stock rom, Da G OC kernel version 0.2 now (0.1 was when 192 min was stable with on demand, though no positive the version numbers are related?). Smartassv2 seems to all but solve the issue for me, but it's not the best for battery because it runs full clock or deep sleep only, there is no in between. I really don't know the best way to try to solve the issue. I'm just staying on smartass for now. It's really a big deal for me because I use the phone as my alarm, and if it decides to do a sleep of death overnight, the alarm doesn't go off, and I won't wake up for work...
Hi, this happen to me before on my white note. I been to 3 att notes so far. First it was very laggy and screen was not that bright. i was getting 1800 in quadrant even on clean install. Took it to att store and they compare to their demos and they gave me a new one. My new white was awesome, screen was perfect and i was getting quadrant scores of 3400 almost close to my international Note which is sold for the LTE. Then after 1 week i started getting the sleep of death. it hapeen 2 times a day and then it got worse to 20 times a day. no matter what i do, stock room no app for 2 days same thing after a day it will start doing it again. I took it to att store swapped for new one. It has been 2 weeks an no screen of death, but again my phone is laggy on this new one and the screen is a bit bright, not as bright as the previous one. If you compare brightness between note ATT and note international on full brightness, the international version is beautiful on vivid colors. You can see the difference right away. it is a huge difference. I guess att disable the screen mode for vivid color on ATT note. Take it to a store and get a new one.
Oh one of the att reps on the store told me one customer had a similar issue and it was related to the sd card. He said they replace his phone 2 times and at third phone it happen again and they told him to remove the sd card and it fix itself. Now that is not the case for me. I still using my same 32GB Scandisk sd card and no sleep of death.
I am having an issue with my MoPho severely overheating and shutting off. But strangely it only seems to happen when I am outside. The first time I noticed it was when I went fishing. My phone had about 80% charge, and when I picked it up maybe 30 mins later is was scorching hot. To the point that it burnt me. And it had shut off. I didn't have it in the sun or anything. It was in the shade inside a bag. I was not able to get it to turn on even with a battery pull even after it had cooled down. The battery completely drained in a matter of minutes. I couldn't even get it to charge in the truck on the car charger, either. It got too hot on the charger to the point it wouldn't even get a charge. This has happened about 3 or 4 times since. It will go from a full battery, get super hot, and completely drain within minutes. This never used to happen in the house, it was only an issue outside. until today. Went fishing, phone had full charge. It managed to hold the battery for a couple hours, unlike the other times, but eventually got hot and died. Then when I got home, plugged it into the charger and went to sleep, woke up a couple hours later and it was burning hot, and had no charge. Other things on it are acting weird now, as well. The screen keeps turning on and off every few seconds by itself. I don't know what the issue is, but I might have to switch back to stock if I can't find a solution. Because eventually this is going to fry my phone. And I don't want that to happen. It is also a huge inconvenience for your phone battery to drain in a matter of minutes and become a useless paperweight when you are in the middle of nowhere and need a form of communication in an emergency.
Has anyone else had this issue and found a solution?

Many people have experienced overheating problems on our cm9. Some people including self have fixed it by just doing a fresh install of cm9 as it seems like just a fluke. Im sure the fact that were running a gingerbread kernel on ics doesnt help. Also, try dropping the battery down to 1200 from the stock 1300, see if that helps.

Someone mentioned changing the overclock from the stock 1300 down to 1000 in another thread. Is that the same thing as what you're talking about? Or is there a separate setting for the battery? I did try dropping it down to 1000 but that's when the screen started turning on and off by itself. And LWP's stopped working properly. They would get stuck and seizure. Even after I changed it back to the default 1300. So I went into CWM and just reflashed the ROM. No more screen turning on and off or LWP's acting weird. But as far as the overheating problem I can't be sure I guess until I go fishing again or put it in another situation in which it's done it previously.

I work outside every day and its bout 100 degrees out consistantly now... I'm not running cm9 anymore but I've noticed I still get the occasional overheat while its in my pocket, it most definitely gets annoying sometimes having to pull the battery and let everything cool down but I think the benefits outweigh the annoyance level a million to one. I guess what I'm saying is you're not alone friend, it definitely happens to me as well. I have my CPU set to 1k though and messed around with undervolting as well and feel like I get a little better results this way. Keep playing with your settings until you find the one that works best for you is the advice I can give. Good luck!

Yeah its the same thing. Remember, our processor is technicallynot supposed to be over 1000 per core for a reason. People just like to push things to the edge. The whole lwp problem is expected and everyone experiences this with the our ice roms. That also is due to lack of proper 2d libs. But I'm glad most of your problems have subsided. Run your processor at 1000 and I'm sure the overheating will lessen. On a powerful dualcore phone like the photon 1300 from 1000 is miniscule anyway.

Alright. I will try it again. But I just love my LWP's =[ I always have a lwp on. I have never experienced the problem with the lwps until I set the processor to 1000. But I guess it comes down to sacrificing my wallpaper to stop it from overheating. If that's what it takes to fix the problem. Hopefully once the stable version is released everything will work like it should without having to sacrifice anything.
It did overheat again the other day. I did have Watchdog on my phone and I was on facebook messenger the other morning and it started acting up, I had my phone in my hand and within a couple minutes it got burning hot, and then right after, Watchdog popped up with a notification that messenger was above threshhold. It was running at 49% CPU or something. And come to think of it I would always get notifications about fb messenger "misbehaving". So I came to the conclusion that it could be either messenger or watchdog causing most of my problems. I deleted watchdog to see if it fixes my problems. I'm hoping it isn't messenger. Because I need my FB. lol. But I haven't really used messenger on my phone since I deleted watchdog. So we'll see. If that didn't solve it, then I will sacfrifice my lwp and set the processor back to 1000.

Fb messenger gets a lot of hate, i cant say thats your problem but you never know. Try out a chat client called imo from the play store instead. It supports fb as well as others and is leaps and bounds better than fb messenger.

Thank you. I will definitely try that =] Thank you. I really hope it fixes the problem. I can't wait for the stable release. haha
I have noticed I have been getting issues with random ghost touches when my XZU has had extensive use or just come off charge.
The one common thing I have noticed is the phone has been warm at the top left back of the phone, CPU perhaps?
I have updated to 257 and most of the other issues seem to be resolved. Just this one.
Here is an example : Was riding my bike with my bluetooth head set on in my helmet, I was streaming radio through 4g and after an hour my wife rang, took the call but the call ended prematurely. All I heard then through the headset was the beeps of the touch screen.
Pulled over and checked my phone and the screen was going haywire. The top left back of the phone was hot. Not super hot but hotter than normal.
Thoughts?

I've gamed for about 2 hours nonstop before, and while it did get hot, it was reacting fine. and when I say hot it was stull under 60.
If it does it again see what the CPU is doing. run an app like
'cooltool'
Take a look at this vid and see how to use it
There must be something making your device hotter than normal. so see what spike you get and see what constant you get also. My guess is that using the 4G modem, plus a couple other resident applications are spooling your CPU up to peak.. that along with 4G modem on full tit will create a bit of heat. In saying that ive never head of anyone having screen issues because of heat.
An easy option is to take it in to the store and seek a replacement. But to get to the bottom follow that video...
