I have followed the pdf from here,
http://forum.xda-developers.com/showthread.php?t=298413&page=2
however.
I have now come to the end of the guide.
and there is a layer on top of the lcd, that I will have to remove first.
anyone have any idea how one removes this layer??
it's the one on the right I can't figure out to get off:

never mind. I figured it out now!
there are to hooks on the side of the phone, and two on the top(where the earsound is)..
take care of the sidehooks first. push a flat screwdriver and push the hook out, and while it is pushed out, push upwards the bottom of the phone. when both these hooks are off. you can go to the top of the phone, and push it down a little, and presto the earphone is relesed!
hope this can help someone in the same position!
I would love to hear from someone doing the same thing.

Now i love my desire... Its fantastic but it isnt without some issues...
One ive noticed that could be a problem esp when your working with reality overlay apps...
The compass doesn’t seem to work that well...
Its slow to respond to movement and even when it does move its horridly inaccurate. north seems to have a room for error of 60-90 degrees.
Has anyone else noticed this? Is it the same for most digital compasses? or do i have a faulty module?
Hi Nutsy,
I've also noticed these issues with the compass in the Desire. I've worked with magnetic compass chips before and I think it's all to blame on the way these compasses work:
To sense the earth's magnetic field they use a two- or three axis magnetometer. Although it's a very accurate way to sense the earth's weak magnetic field, it's also very sensitive to any other magnetic field. That means that the presence of ferromagnetic materials (like iron) or electrical currents in the vicinity might really screw up your compass reading.
So electrical wires, iron piping, laundry machines (almost anything that you would find indoors that runs on electricity or contains iron), will interfere with your compass.
a good alternative would be to use a gyroscopic compass like they do on submarines, but I don't think these fairly expensive devices aren't used in mobile equipment yet. So the only thing to do is to stay away from anything that might interfere.
The slow response to movement might be caused by internal filtering. These analog sensors produce quite an amount of measurement noise. In order to cancel this, they probably use some sort of filtering algorithm like this one:
step 1 -> Take a new sensor reading.
step 2 -> Add it to a buffer that contains the last 25 readings.
step 3 -> Calculate the mean value of all measurements in this buffer. This will be the compass heading that is sent to Android OS or your application.
step 4 -> Repeat this cycle every 25 milliseconds.
Hope this answers your questions. Of course if you compass readings never make any sense under any circumstances, the thing might just be broken...
Friendly regards,
Joost
Ps.
There's an App in the market called "Metal detector" that actually uses the interference "problem" with the compass to detect ferromagnetic metals.
Wow Thanks for the really detailed reply...
Im glad its not just me then... Didnt really want to RMA it over a dodgy compass unit.
And thanks for letting me know about that app... sounds usful... I guess it could be used to detect wireing in plaster as well?
You're welcome.
In theory you could use it to detect metal or wires in a plaster wall. I've just tried it, and it works quite well. On the other hand, I really don't want to risk electrocution by trusting a telephone to find electrical wires...
My compass is shocking. Actually points closer to South whenever I open Compass or a programme which uses the compass like G-sky. I have to calibrate it every single time.
Thing that annoys me, is if I calibrate, then exit the programme and immediately re-open the programme, it doesn't remember the calibration, it reverts to pointing in a ridiculous direction.
I want to hit it with my fist.
Addtitionally, think it's broken?

Yesterday I found out the same thing... Sometimes I cant even get it working after calibration. I was beginning to think that this happened because I dropped it once pretty hard. What should we do next? Can this be solved by replacement with warranty or something?

Make sure your phone isn't in a case which uses magnets to keep it closed, as they affect the compass. If you're affected, take your phone out of the case and try again. Also, try out in the open, away from structures which may contain a lot of ferrous metal.
In my case the problem is due to powered-on wi-fi module. Turning off wifi, compass works fine. Could Anyone elserepeat my experience?

Yes I know that. Tried out doors, and wheres no metal... When I had the G1, the compass worked normally.

Just went outside to test it again. And I think I found how to get it working. If i launch the compass application, and try to turn the phone in the flat position (on its back), then the arrow moves in random directions. But if i lift the phone that it is facing straight to my face, and then turn left and right a few times, like a steering wheel, the compass "calibrates" as I can see. And then when I lay it down again flat, it starts to work normally. Can anyone try this, if you understood my instructions?
A more accurate way of calibrating the compass is by rotating the phone twice around each axis, ideally you should do this away from anything metallic or any interfering magnetic fields preferably outside.
Er......
Where is the compass?
I dont seem to have a compass! In my list of apps there just isnt one called compass...
The Analogue Compass app is very buggy for me so I use the Compass app -> http://www.androlib.com/android.application.com-apksoftware-compass-qAC.aspx
When taking readings, I;
Always have to recalibrate on startup as far too many objects cause large interferences within the sensor making it go astray, even the charging cable causes it to go berzerk. The known working routine is to calibrate by fast twisting and turning the phone [I do it after running the built-in figure 8 calibration routine]
Keep it mid-upper body height with no metals nearby (jewellery/belt/metallic objects minimum >5ft away), holding still and level across the x-axis
Point the upper-end of the phone in the direction I want the bearing of (this depends on the type you use though, I use the digital type)
I spin the phone around and then retake 2 more readings for a total of 3 readings - averaging them out for a final mean reading
I only have 2 directions calibrated through professional consultation when this room extension was built a few years back and know the rough directions all sides this property faces, but in particular, I'm 100% sure of the exact degree reading one wall faces. This app using the built-in compass sensor reads that bearing spot on everytime after calibration (fluctuation is 1-2 degree max).
Some friends in a Lithuanian Android forum, suggested to do this, like it is shown in the video. Works perfectly every time. And I thought that something was wrong, because I never had to do anything like this on my G1.

Ok - forgive me if this is the wrong place to ask this...
I've used the Google Maps and navigation a couple of times now, and it's really good, but I haven't used a cradle with it. I foresee and issue however.
The charging port on the phone is on the bottom most side of the phone, however, for us in the UK, this could prove to be a problem when used in a dashboard mount. In UK cars, the lighter socket which provides power is located in the central console of the car, however, the screen only rotates one way for landscape screen orientation. This means that the charging port is point away from the source of power. In US cars, or EU mainland, this is ideal, but for us in the UK (and other places where you drive on the right hand side of the road) it could prove problematic.
So, the question I have is this.
Is there an app on the market, which enables the screen to rotate both ways - ie anti-clockwise, and clockwise, to enable dash board mounting that's less problematic? I've had a look on the market using the obvious search strings, but so far my searches have been fruitless.
Any ideas?
FWIW - I did a brief google, and by the sounds of things, this issue could be getting addressed in Froyo, hopefully...
but for us in the UK (and other places where you drive on the right hand side of the road)

We drive on the left side of the road in the UK, unless we're drunk
I guess you mean the driver sits on the right hand side of the car.
The nex-desire rom off here rotates 360, yes even upside down lol. It's great if you don't mind losing sense!
Lol - when I meant right I meant "correct" side of the road...
Yes - I also meant that you sit in the right side of the correct as opposed to the left - it means that the phone will sit on the right side of the console which isn't so good for plugging the charger in...
Well, that rather depends on where you site the phone.
I've always had mine roughly directly above the centre console, so the location of the charging port has never been a problem for me.
That being said, I find Copilot very good to use in "portrait" mode, so these days I seldom bother with anything other than a vertical orientation anyway.

The compass is about 10' to 15' out on my phone - i normally wouldn't care that much except the built in locations app uses the facing direction instead of the travel direction... so it looks like you are driving down a road diagonally.
Any ideas of how i can re-calibrate the compass - or make locations use the direction of travel instead of the compass?
Thanks
Kris
Maybe it is a magnetic compass, and hence points to the magnetic north?
BTW I have the same with mine. Mine is about -15' out.
The GPS Status app has something to 'calibrate' with, but the results stayed the same IMO.
Well I think that really su* ... y can't it just use the direction of travel like other software - or have the option
I know man, have the same issue. I have proper compass 'analog' and a digital one and the one on hd is a joke. Tried everything, it's still off. Most likely it's software issue here. Not sure though, but looks like it. Mine is -20 and less or more useless.
Mines off about that too.
When using the one in my Hero, I could wave my hand in a infinity symbol shape (or figure 8 on it's side) out in front of me for a few seconds, that would get it fairly accurate for a little while. Haven't tried it on the DHD, but it might work?
I have exactly the same issue. Annoyingly it is also 10 to 50 meters off on my location......
HTC Hub also shows me 20 meters off of my location.......
Anyone have a solution let me know!!
Good i managed to calibrate it to be fairly accurate.
There is still a minor distortion which i assume is caused by battery but it's an improvement never the less.
Basically go to maps. Then hold your phone by pointing your screen towards the sky and start making infinity symbol in the air. In such way like if you were trying to paint it on the wall in front of you. Do it for about 30 sec, then it should show you a fairly accurate readings.
Hope it helps, worked for me.
Thanks Madeinru........ it helps a bit but hasn't completely fixed it.
Probably will go back to the shops and exchange it - its still annoying the hell out if me
MadeIRu, could you describe your method in a lilttle more detail. I thought you had to hace your device towards the sky and make a movement like drawing an 8 horizontally al the time the device facing the sky. Thanks
Hello there
What i did is:
Switch on any compass app or maps.
Point your device with your screen towards the sky, same way when it basically lies on the table.
Then start making 'infinity' like sign in the air while your screen points at the sky all the time.
Just like you wanting to paint an 'infinity' sign on the wall.
Just like the guy in this video:
http://www.youtube.com/watch?v=qOkErjFKiD8&feature=related
But i was pointing my screen upwards all the time, so my phone stayed in the same position at all times.
Do it for about 30 sec or so.
Regards.
download compass from market, it has a calibration feature builtin
not sure if it will help you're situation though, i guess it's supposed to.
Disclaimer: I am just stating what worked for me, so if anyone's warranty is dismissed, or phone further breaks, it is not my fault.
Hey guys, so my phone started bootlooping about a month ago, but I have my warranty still so I am eligible for a G4 repair, (as well they agreed to fix my G2 from two years ago). Anyways, the problem is I didn't have some contacts, pictures, etc.. backed up so I needed my phone to function for about 20 minutes to back them up. I tried the freezing method, every button combination possible, even held the power button down for 10 minutes. Nothing worked. Until I found this reddit comment from a while ago.
https://www.reddit.com/r/lgg4/comments/3vsebk/retrieve_data_from_dead_g4/
The comment by.. uh... "Irapedyourcat" about heating the phone helped me. Now I used a hair dryer instead, and basically followed this video tutorial. It isn't the greatest, and one of the videos is 40 minutes long, but I skipped through most of it and you really don't NEED to watch it. He just mentioned some bumps you can experience and decently described the steps.
https://www.youtube.com/watch?v=TkMhaLryn-A
https://www.youtube.com/watch?v=uN6baDuozms
So I'll just go over the steps of what to do and what materials you need.
Materials:
- Hair Dryer
- The phone -_-
Steps:
- Take the battery out of the phone and be ready to put it in. (Keep nearby and away from the hot air of the hair dryer)
- Plug in the hair dryer and expose the back of the phone with the back cover off.
- Watch the time for about 3-5 minutes. Don't go over I would say 6 minutes.
- Slowly start from the bottom left corner of the phone, and move up to the top part of the battery hole. (Don't go over the buttons).
- Then from there move a little to the right, then move back down slowly. You want to leave about a pinky's length from the phone to the hair dryer.
- Just keep zigzagging until you reach the bottom right. Then go up to the top right corner, to the right of the camera, and heat that area for a little bit, definitely a shorter time than the bottom area. Then skip the camera and then move to the top left area.
- After you do that about twice, or for about 4 minutes, feel the phone. It should be really hot. Like enough to go "Ow!" Not jerk your hand away or it'll burn you hot but maybe a window of a car left in the sun in an empty parking lot for a while.
- Once you feel the temperature is right, (I'm not sure if this helped or not, but I did this process twice and the time where I did this the phone turned on for a longer period of time), focus your hair dryer solely on the 4 little gold things that your battery connects to. https://ibb.co/cKSnQa
- After you do this, turn the dryer off, and put the battery back in
- Start your phone, and once the logo shows up, plug your phone into the computer. (Or if you don't use PC, you can just use the phone and put it into a SD card, or use a cloud service. Personally I think the phone can stay on longer if you just control everything from computer but whatever works. If you DO choose to use a computer, make sure to click "allow" when it asks for access.)
- Back up away! If the back up is taking a long time and the phone starts to cool down, what the guy in the video did, and me too, I heated it with the dryer for about 5 seconds at a time, just on the bottom half of the screen and some of the sides.
One thing to mention is that the phone does get really hot. That's the point, it has something to do with "melting" the cicuit board and some connectors together or something??? I'm not really sure so if someone clarifies that, that'd be pretty cool. Anyway you will get warnings that 1) your phone is at a very high temperature and then 2) that if the phone gets any hotter the phone will shut off. (That's what happened when I heated it too much while it was backing up because the phone was starting to cool down so just do it for 5 seconds every minute or so!) https://ibb.co/nrfwJv
I'll mention again that this could work or could not work. This is pretty risky, I'm not gonna lie, but if done properly, you'll probably have a good chance of succeeding. The reason I'm posting this is because I kept thinking "what if I saw this right after my phone started bootlooping?", and it would have made my life so much easier if I found this way.(I've been without a phone for 3 weeks, just needing to send it in for repairs, but feeling that I could somehow manage to back up my files, but I didn't have a way). So I decided to not be lazy and write this. It's less risky than "baking" it, so if you're considering that, then try this first. Hopefully no one made a post exactly like mine because that would suck because I'm super tired right now but I hope this at least helped one person. Thanks and good luck!
