I have bought a used HTC HD2 which freezes very often. Unfortunately I found out that the device freezes when it gets more than 36.5 degrees. I am incapable to make call which take longer than 5 minutes- its very annoying. The problem is, that I can't send the phone to HTC in my country because I got the device from Germany. So I have my warrantly in my country.
The problem exists in Android and Windows Mobile. I have tried many different ROMs. I've read serveral posts about freezing problems and it is definitly a hardware issue.
Is it possible or has someone fixed the freezing and reboot problems with his HD2?
I am very sorry for my bad English.
probably not, had the same overheating/reset loops issue, finished having mainboard replaced under warranty, no problems since
The problem is, that I have no warrantly and replaceing the mainboard cost 100€ or more...
Is there any way to disable the temperature sensor that the mainboard doesn't reboot?
Looks like you bought a flawed phone. Can't you just return the phone to the vendor you bought it from? Or insure it, and claim on it? At one stage I had my phone covered by house insurance, phone insurance and my bank also had it covered as part of a premium account I had with them, surely you have something along those lines you can claim though?

The problem is that I can't return the phone
I need to fix it myself but I don't now how to do it.
I found a post which maybe help but I am afraid to completlely damage my device.

had a same problem...
my solution was screawing the middle battery pin under cover...
the hd2 have must have Temperature senzor...
the hd2 have 3 pins under battery cover, 1 = +, 3 = -, and the middle pins is the 2 = ?
i think the middle or the pin nr. 2, is same as ACPI in desktop or notebook, Advanced Configuration and Power Interface,
Operating System-directed configuration and Power Management,
so if your middle pin is screawed, the powermanagement tell to device stop boot!!
or if the pin dont make a contact with battery - the powermanagement canot corectly detect the Temperature and the hd2 owerheat, then randomly restart...
its only my teory, my middle pins was screawed, im take it to the right position and my device worked well... but i want more and more and i broke the middle pin
after that the hd2 boot, and worked but when i want to do restart dont want to boot...
now my hd2 is in service center... so for all i want to say:
warrnig!!! dont youse the power or angry when u want to screaw the pin back
its only my teory, im not the electro technic...
sorry for my english, but i think everybody understand what i want to say

Has anyone done this? Or can anyone please share a pic with the three battery contacts because I don't know what's exactly the right position.
if it's overheating that easily, the motherboard needs to be replaced. Not much we can do to help.
Its very strange because 36.5 degrees is not very hot and there are HD2s which work when they get 50 degrees. I don't think that something is overheating. In my view there is something wrong with the temperature sensor. Maybe the sensor is reporting that the device is overheating which isn't true.
Hi,
my HD2 crashed when temperature was more than 34,4°. I observed that this problem gets more and more often. It began about 2 or 3 times a week and ends with crash after 2 min using the device. I gave it to sevice center and they replaced my keyboard. (btw: all Software using a hardware-dependent key is no mor working).

try using some "Tesafilm", and put it on the battery there where that pi is before screwin it off... maybe that helps.
@mm2700: You've got a PM! I had nearly the same issue here in Austria with a German HD2.
How do you measure the temperature?

This is an amazing device. However, I figured out why the soft keys at the bottom are breaking! (By breaking I mean when you touch them, the light goes off and goes into a key lock disabling the menu key and the back key)
This phone most likely has a heat sink sitting on the bottom left corner of the device. When this phone is in a high temperature state (either lots of constant usage or a hot room) the heat sink begins to overheat causing the heat sensitive soft keys to think it's being held down.
Edit: (That or the GPU is sitting in the bottom left corner because i noticed when I run an emulator, it freezes the buttons really quickly. Especially if you get a text message in the middle of it)
therefore this is a HARDWARE error. Samsung, please fix this. Don't let this amazing device go down the ****ter. Either add a stronger heat sink, or like most laptops now-a-day, install a vent for the air to leave the phone.
Temporary fix?
Shut phone off for like 5 minutes, and place it in a cooler area.
Specs:
Stock Samsung Galaxy Firmware. Straight from the bell store. (I had to do a few wipes to exclude outside variables)
Phones these days are going to need a fan built in because they're getting too powerful.
I haven't made a forum search because I didn't want to get lazy and post this if I didn't find one.
TLDR: Hardware issue causing overheating.
I don't think the keys use heat. (Maybe it's a bug with the Bell variant). It's a capacitive touchscreen, so most likely uses electric current. How do you know the keys are heat sensitive?
it only stops working when its warm.
i use my phone constantly and i have never had this issue. actually, i have had two, as i returned the first one after two weeks for one that has the 3 button recovery enabled. not only have i never had this issue, but i have never come across any mention of it in any of the forums i frequent.
When I bought my phone, I was able to use both vol up+ home + Power, and the vol down + home + power, so I don't think I have the non recovery model.
I don't think mine has this problem or i haven't suffered from it yet anyway. Today the phone got really really hot, i was in an online multiplayer game whilst it was charging. I was aware the phone was becoming quite hot but i needed to carry on gaming lol anyway, for the first time i got a system message stating that 'battery charging had been paused due to excessive heat' so this shows the phone was hot. Well this finally got me off my game and i used the back key to exit without any troubles at all. You don't mention getting this error so does that mean mine was at a higher temperature?
I agree with andrewluecke about the keys being responsive to 'electric' and wonder if maybe you had sweaty/moist fingers whilst trying your keys, it does mention in the manual about irrational behaviour due to moisture.
I have a Bell phone and never once had this issue. I would take your phone back.

make that two
the OP definitely have a defective unit
maybe some one dropped it when it was being demo-ed or something like that
else it doesn't make sense why those buttons would be at those horrible conditions

Well, I agree. I have the unlocked I9000 phone, and have never experienced this issue...
You probably have an intermittent fault caused by dodgy joints within the phone.
Get it repaired..
Nothing that could warm up is at the bottom http://www.careace.net/wp-content/uploads/2010/06/galaxy-s-disassembly-10.jpg (right)
Only the vibrator and the microphone
exactly, the stuff that warms up are the GPS and Wifi and those are at the top where the USB plug is
Yeah it's probably to do with a dodgy contact rather than heat, plus the touch buttons at the bottom are just an extension of the screen and so are capacitive, not heat activated.
Logicalstep
+1 for "never had issue"
You see that your buttons lock up when it gets warm and you automatically assume it getting warm locks up the buttons?
Ever thought that something in your phone was overloading and causing it to heat up at the same time causing the hardware keys to lock up?

And thats the increasing problem with XDA (and the internet in general).. It's becoming easier and easier for people to make ridiculous assumptions without proper proof. It's one reason why we should always question everything we see, if there isn't a reliable source, or proper testing.
Dear all,
I've performed an exhaustive search all over internet and in particular in XDA developers site and I could not find any information.
First some background just for info:
We are an amateur group that launches high altitude balloons to the stratosphere. There we take photos, videos, we measure temperatures, accelerations, pressure... (I guess it is quite known the HAB activities). Apart from other equipment’s (arduino based) and payloads, we always send an android phone as a recovery system as we can send an sms to the phone to ask its gps location. We also takes some photos during the flight with the phone camera and record GPS, the accelerometer and gyro data.
We would like to save some mass (to reach higher altitude) so we are thinking to launch only the motherboard and the battery. I have tested it with my galaxy S2: I opened it, extracted only motherboard (usb included) and battery (with no screen at all) and I could switch on, and operate it through MHL (hdmi) and a bluetooth mouse.
So we decided to buy a second hand galaxy note 3 (better camera resolution, battery, more sensors...) with a broken screen as no needed.
The note 3 works perfect with the screen attached again via mhl (even though the screen was not working). BUT when I remove the screen, the phone cannot be switched on... it enters and endless bootloop.
I guess that this is because the boot process checks somehow the presence of the screen.
Now the real question:
Do you know if there is any method to use the phone without the digitizer plugged?
Maybe replacing or reconfiguring the boot/kernel/rom to avoid the screen check? No problems at all with voiding the warranty (is a destroyed second hand device) or rooting, or flashing...
Many thanks!

I know this is not what you are asking (which is interesting in itself) but why don't you leave the digitizer plugged? It should be like just 1mm or so, and only a few grams.
Maybe this is unclean workaround: how about let the phone completely booted and remove the digitizer?
I would suggest disabling the digitizer and/or display in a custom kernel build first -- if you can get the device to still boot fully, you can try removing the hardware connections. If it doesn't boot, then you need to figure out what in the OS relies on these features.

Thanks xclub101
Our workaround is indeed that one, to remove everything appart from the digitizer (frame, glass, wacom...). But we also thinking in volume reduction that also impacts weight. Considering that we are tipically launching 500g, 50g is 10% that in terms of balloon ceiling could be 3 or 4 km (not that much, but in any case above our actual limits).
In any case, I do not want to diverge from the original question. That is to use the phone without the digitizer.

Thanks Crescendo
Yes, it could be a solution, I will try to do it. However, once integrated within the payload, it could be not so easy to remove it.
And what would happen if there is a reboot during the flight? (sometimes it happens, mainly due to failures in the battery as a consequence of the cold temperatures up there, almost reaching -50ºC). Then the phone wont boot again

Sounds a good solution, but I'm not an expert in kernel customization, nor cooking... If you (or any other) could guide me in how to do it I could try.

My father dropped his phone. The phones display isn't working anymore (kind of). It stays black. The LED works, the buttons light up, sounds function but the display is black. When pressing the home key the buttons light up for aprox. 1 second then turn off.
Help would be appreciated because I am not a Samsung person
Please help!
(the warranty is still active)

Since its just screen then just take it to them. Thought it was broken.
Although you have warranty, seems it would be hard to get it a service center to repair it without a cost to it. Best bet take it to a Samsung service center and try your luck(they will charge you more than likely). Seems the device is too damaged for normal operational use.

XDA does not condone doing things to circumvent OEM warranty. I think people can figure things out on their own.
Considering the device is under warranty, then just send it in for service. Clearly a connection came loose on the display, and disassembly will viod the warranty. Best left to professionals.
The member was asking for advice.

And I totally agree ^^^^^
Well, for info, I had an Iconia A501 tab (best tablet Acer made). It was a die-hard beast (until it became my 2.5yr old little girls tab) :laugh::laugh::laugh:
After 1 year slamming around, dropped I don't know how many times, some nand became corrupted. Now, don't laugh, but I removed the MB and put it in the oven for a bit (10 or 12 min). And shazzam! Could reload the OS.
You see, these OEMs "cold solder" the connections, chips and such, and dropping can make them come undone or lose contact. So a bit of heat, then pressing the chips back in place, can sometimes work.
But some months later, I finally put it to rest. Just too much abuse :laugh::laugh::laugh:
Good luck Mate, hope they get it sorted.
Iam planning to buy moto g4 plus, i heared there were 2 batches with 2 types of screens LGD and BOE . please tell me how to check the screen details of this mobile. and also please tell me what should i check before and after buying this mobile as this is highly controversial model. Thans in advance
Install DevCheck System Info. Search for the 'Hardware' section, and then scrolll down till you find "Panel", it displays which screen do you have (BOE or LGD).
You shouldn't check anything else, since the only bugs of this model come from the screen (always can exist an exception, like in every smartphone).
Short story:
LGD = possible image retention (can be fixed).
BOE = possible ghost touches while it's connected to a PC/Charger (can't be fixed).
Thank you
Thank you very much ..
Sir,
I just found that my screen is an LGD . should i worry about image retention ? is it common in all devices ? (my device mfg date - september-2016).
Is there anything else should i be careful at or worry about ? please suggest..
thank you

Yes, it should. Since it's a manufacture fault recognized by Lenovo. Some BOE screens will never suffer from this fault, is not my case, mine has ghost touches when is conected to a PC, since the zero day, but it is not big deal for me, obviously is a clear failure and can be very annoying for these who need to use their phones conected to a PC or wall charger (in my case i never faced ghost touches while is connected to a charger).
@pinke93
In the case of the screens made by LG, the image retention can be corrected setting all the 3 RGB values to 240, you will need root for this. Some people uses a blue filter app from the PlayStore that does not requires root (i didn't test this method).
I "fixed" a normal moto G4 from a friend, with LGD screen doing the RGB value re-setting.
You should not be worried about something else, and is not a certain that it's going happen to your device.

Thank you very much. I agree with you. It's not a problem at all since I do not use my phone that much while it is charging. Moreover the turbopower technology gives me at least 80% charge in nearly 1 hour or so. But in emergency cases, say during doing a phone call, sending important messages, when the ghost touch starts popping up it is indeed really annoying. So as per your advice, I will have to go to the service centre to replace the display panel. And by the way I have rooted my device on the very first day I purchased my device.

Same here haha, i bought this device because my Nexus 5x die, that model has a terrible design failure (same as LG G4), suddenly it went turned off and never could relive it (hardware break: the welding that holds the CPU attached to the mainboard get broke). So, the ghost touch issue for me is literally nothing.

Yes. Despite packing some decent hardware, the Nexus 5X always had these problems. Even some had filed a lawsuit against google. But I don't think its entirely google's fault. It was the fault of the OEM's, and LG (for Nexus 5X) and Huawei (for Nexus 6P) faced lots of criticisms from the customers.

But, I dont want to root my mobile . iam not a techie ,not good at this kind of stuff, so dont want to void my warranty... as you suggested i think colour filter apps might work.
And, Incase if i get this issue in future, can i request the service center to change my display to boe ?
when i connect my earphones to moto g4 plus, its not showing any icon on status bar ( headset icon that we generally see at the top ), please tell me how to get it.

The company is bound to replace your screen under warranty
Also you wanted headphone icon in status bar
For that swipe down from top on home screen and long press on settings icon you will see it rotating then leave it. You will get a toast notification that system ui tuner ....
Then go to settings you will see a new section at bottom called system ui tuner under that you will find status bar and then you can select icon to show
Thank you @ Sobhan Bhuyan.
will try it
