What exactly is the DoA and what are its terms and conditions?
Also what all should be checked? At the store we should check for physical damage right? and after that all that stuff to check about dead pixels and all..could someone give a list of it?
thanks

After checking for physical damage(and obviously testing for the phones basic functions like making a call, a text etc.. I'm sure you get what I'm saying :laugh you could dial *#0*#. That menu deserves one purpose which is to test several functions of the phone like the phone sensors, brightness, IR, touch screen, hover, camera, sounds and a ****load of stuffs that the phone can do.
Oh and DoA stands for dead on arrival, means that the phone doesn't even turn on out of the box. You should be able to replace it, I mean whose dumb enough to leave the store with a DoA phone?
calls, text messages, data connection (both 2G and 3G, 4G??), auto/manual network selection, check if it is unlocked with 2 sims by different providers, bluetooth, wifi, gps, camera, NFC, loudspeaker, headphones jack, cameras (front and back), g sensor, proximity sensor, auto brightness sensor, power button, volume rocker, sd and sim card slots, usb plug, in call volumes and sound, speakerphone all at different sound levels, screen - dead pixels, flickering, scratches, back cover for broken clips, check all samsung gestures, ask for leftover warranty, if it has had a screen protector you might find hairline scratches underneath, check if it looks as if it has been disassembled (any marks on the screws) you have a lo to do

Well this could be really e serious problem:
using my X7500 I noticed the display light level decreasing a little bit. I supposed it could be a wrong impression of mine. So I tried to push the upper side of metal case and I noticed the light coming up. Then I made a little pression on the same edge (near HTC brand as well the lower opposite side) and the light decreased again.
I assume there must be a problem with led position under metal cover. It's eneogh a little pression to have problem with light display. Maybe it could depend on "shock" due to the keyboard hook-up that could damage led connector inside...
Please help and tell me if you have noticed same problem...
Please any suggestions for this problem?

Tried the suggestion you made but no problems here either asci. Maybe your unit is faulty. Try returning it due to electrical shortage or something similar. It certainly does not sound normal.

Yeah, tried that - absolutely nothing happening.
I turned it back to assistence...it seems to be an isolated case, and they could tell me when I'll have it back.
HTC customer care: bad assistence:
1. they didn't solve my problem yet;
2. they didn't answer to my mail.
I purchased an HTC X7500 on 21.05.2007. After two days it immediately showed some problems related to LCD display. In fact on making a light pressure all around display metal case, especially near the hardware buttons on left side, the LCD background light became weak as it loosed brightness.
I brought it immediately to a technical customer care for reparation. After two weeks it returned back but the problem related to display brightness still persist.
1. The backlight is weak and display is not so bright and not stable too as the very first time I tested it. Now when I connect 4 in 1 cable or mini USB one, and some time even when a set stylus in its lodging, by doing some little movement of the cables connected or of the stylus in its lodging, the backlight display increases to its normal brightness level for while after that it turns itself weak so that display colors appear not vivid and with a lack of brightness. Before testing it I verified that all backlight levels were set on maximum level with any power option.
2. When I browse through menu icons and select them (without launching application) their appearance is not stable and it seem to flicker.
3. If I set a white background on display it seems to be completely crossed by horizontal stripes and its appearance (color and brightness) is poor.
So today I had to come back to HTC customer care point to leave it for the second time in twenty day.
I would like to point out that I am a professional user and I’m really disappointed about it. I had to bring my device to a technical assistance point twice and the first time, I had it back not repaired.
Considering that, and also considering its high price and that it came with original unmistakable manufacturing faults, I am asking to HTC for a replacement of the device with another X7500 perfectly working.
Best Regards.

Good luck and let us know how it turns out. I hope HTC doesn't become so big that they stop listening and taking care of their customer. I would hate to look for another high end phone manufacturer.
Arrived today...replaced.
I'm having trouble with the proximity sensor on my HD2. It works if the phone is pressed up directly on my ear, but if I move it away just the slightest, the screen comes back. Is there somewhere I can access the proximity sensor settings, and give myself a bit more room? Like, say, anything inside an inch shuts off the screen?
ROM info is in the sig, and I'm using the HTC phone dialer, if that makes any difference.
http://forum.xda-developers.com/showthread.php?t=624206
Aw balls, I hate it when there's a thread for this, and my impatience with searching failed to find it.
Thanks!
Doesn't sound like that app does anything for the sensitivity, unless i missed it. it just makes the screen stay off after the sensor is activated.
However the point of the proximity sensor is to shut off the screen so your ear isn't pressing buttons. If you've got the phone far enough away from your ear to reactivate the screen, then there's no longer a need to turn off the screen to prevent ear dialing.
If you're worried about power savings, the screen should shutoff in a minute or so, depending on your screen timeout options

correct, I haven't found a way to change the sensitivity for it, just turn it on or off. I believe the way the sensor works like a motion sensor in a store, either you are there or not... Hardware driven on sensitivity, not software.

I actually posted about the sensor in another post. The sensor is just an IR LED and a photo diode. The photo diode looks for the reflected IR when the phone is near something like your ear.
The IR LED only turns on during a phone call. Try this get a digital camera with a live preview and aim it at the 2 dots where the proximity sensor is, you'll see the IR LED light up when you initiate a call
The same photo diode is used to alter the screen brightness depending on the ambient light that hits it

It won't be in the upper portion of the phone, as this increases the strength of the radation the head is exposed to. I believe there is a law prohibiting it from being too near to the skull. Which is why all antennas in modern phones are internal and not placed by the speaker at the top of the phone.
Although this seems to not apply to GPS, Bluetooth and Wi-Fi, which is what those wires by the speaker at the top of the phone are.
Class 1 Bluetooth devices can cause exposure to radiation similar to that emitted by a cell phone if they are operated in the immediate vicinity of
the body. Bluetooth devices are designed to limit the radiation power exactly to that actually required. When the
receiving device indicates that it is a few meters away, the transmitter immediately modifies its signal strength to
suit the exact range, which reduces the total emitted radiation and signal interference (IT'IS 2005).
A study commissioned by the Swiss Federal Office of Public Health (FOPH) measured SAR for several Bluetooth
devices, including two different class 3 hands-free cell phone headsets. The headsets tested had SAR values of
0.001 and 0.003 W/kg, which is 34 and 12 times lower than the SAR of the lowest-emission cell phone currently
available (Swiss Federal Office of Public Health 2009a).
The article can be found here.

The cell antenna is the strip on the bottom below the battery door,the wifi antenna is at the top right (if looking at it with the screen up),and the gps antenna is at the top left. There is a white cable that is supposed to run from the gps antenna to the bottom side of the main board,and a black shorter antenna cable that is for wifi that plugs into the top part of the board. I have a pretty strong feeling that the person that fixed your phones (whether that was you or someone else) probably didn't plug that cable in the right way.
<EDIT> By the way,if either of you want one that works the right way/for parts,I have one for sale that the volume buttons don't work and the lcd is cracked,but everything works other than the volume buttons.

Anyone ever have any antenna issues without taking apart the phone? my phone just developed issues with dropping wifi unless im close to the router, im guessing an antenna cable is loose. and for those who have fixed the antenna issue, how hard was it?
according to the HD2 manual, the antenna is the bottom 1/5 of the phone

The WiFi antenna is located at the right of the camera watching the camera in the back panel. If you watch this video, http://pockethacks.com/category/service-manuals/, you will see that the Bluetooth/Wireless atennas are located together and connected to the main board with a coaxial cable.

What this guy said +1
I find myself in a similar situation to nedko76. I had to take my phone apart but just the case away from the screen circuit boards etc because the plastic led shield had come lose and was touching the vibration device causing a strange noise.
So i managed to get the phone apart (which was not as easy as shown in the video) i didn't touch the screen part at all, put it back together again and switched it on. To my relief it switched on, all looked good, the noise had gone from the vibrator however the only thing that is not working is the wifi.
I'm hoping someone has resolved a similar issue without the need to reopen the phone again as i can't help but think i will do this and see nothing wrong. Which would either mean i've somehow damaged the wifi circuit board or something else.
I use wifi alot and will miss it loads if i can't find a way to fix it.
As already mentioned, WiFi antenna seems to be feeded by a tiny cable, it is probably using some tiny coaxial connectors, those are usually relatively easy to accidentally disconnect. I would start from looking at those and making sure they are "wedged in" properly.
I have taken the phone back apart and checked all wires are pushed in and everything is connected from what i can see. But still nothing.
Wifi switches on but just stays at scanning. Now does that mean that the wifi is working but the antenna is the issue.
I'm just wondering if its a software issue somehow. As i never touched any part of the board, or antenna etc whilst it was apart and like i've said i couldnt see anything out of place or loose.
Dude,
There are 2 brass clips on the top right of the motherboard which attach to the rear case antenna. Make sure these brass clips are correctly functioning and working. There are 2 for the gps at top left big ones from memory then there are 2 at bottom for radio antenna and two at top right for wifi.
Make sure these are all ok...
If you can post a detailed photo(s) I can give you more assistance. Zoom in the motherboard and the clips if you do provide pictures.
Good luck
Yeah i saw these when i took the case back off yesterday, i looked at all them to see if there were any differances, any broken off etc but they all looked fine. I did lift the ones for the wifi and bluetooth just a little bit to make sure when the case went back on they would be in contact. But still no luck.
I find it difficult to believe that just taking the case off pushing a little bit flashlight plastic back into place would really stop the wifi/bluetooth from working.
I'll have to keep searching the web to see if anyone has resolved the same issue and what it actually is. It would be interesting to see if people take their cases off then just put them back on again if they have the same issue or whether somehow i've messed something up.
Dude, show me a pic of motherboard to see if all your connections coaxial are ok.
Otherwise, your hardware maybe fubar. I have opened mine several times and no probs.
Right I took my phone apart again this morning to double check everything. I noticed the cable attached at the bottom as mentioned in previous post. It lifted off a bit too easily, so I positioned it correctly and pushed it back down, my WiFi now works. So that was my issue.
So my advice would be if both your Bluetooth and WiFi do not work, it is more than likely the cable is lose. (more likely if your phone has been a part obviously)
Thanks for everyone's help and advice on here. no fubar hardware here thankfully

I'm also experiencing this after changing a smashed screen... The accident it self did hardly cause this since I used the phone with full performance for about a week between dropping it on the ground and draging my sorry ass to the retailer. Since I don't intend to open this stuff up I guess I'll have to go back there. I will refer to this site if they try to indicate that their sloppy disassembling isn't the reason... Please, feel free to boost me with more cases like this...
I have replaced the screen myself and have the same problem with Wi-Fi only.
I dont know why Wi-Fi run only without the battery cover.
I' m trying to torque chassis for looking if it is a mechanical issue but it seem not.
I've tried also to connect the two little contact they are at the same level with the bottom of the battery looking the phone from its back without the cover.
I've not found yet any relevancy with the presence or not of the back cover related with Wi-Fi transmission.
I remember that when the phone was disassembled, I have slighty lifted with my finger the bigger one of the two lamellar contact of Wi-Fi antenna; anyone know if this could be the cause? Must to touch these contacts chassis or not ?
nothing else ?
Howdy.
On the Model: SM-N900W8" Bell Galaxy Note 3
Basically when in call, Here is a problem that is reoccuring for the past few weeks ever since a couple over the air (ota?) updates I have received compliments of google.
Enabled right now, via "call settings" = "Turn off screen during calls" is CHECKED with Green checkmark.
Just handset call, moving handset to ear to talk. Handset goes black. When removing handset from ear to click hangup, or press buttons, ie to "see" the screen... screen is continually black. - Fix = PRESS HOME BUTTON... brings screen up...
When on speaker phone call, screen is lit. Move hand to the first of 2 sensor circles by the main earpiece part, screen goes black, but does not return on.
I have tried *#0*#. = "Connection problem or invalid MMI Code". - However try again, and I get red green blue receiver etc etc.
I clicked "sensor hub test" and it went BLACK.
I had to click home button, unlock screen, and I get a white with black text stating that..
INT Check: OK
FirmwareCheck
MCU Firm Version : ST0113090300
Bin Firm Version : ST0113090300
MCU Name: STM32F401CCY6B
"blue letters" PASS
I don't see how it passed, a screen went black, did not return, just went black..
Hit the back button. Tried "TSP HOVERING". That works fancy, drawing green squares everywhere...
Under "SENSOR"
I move the hand over proxmimity sensor - ACD goes to 1000+ when I put my finger over it and the screen goes green with black fonts of the prox, acceler, barometer, lights, etc...
Prox is native when sitting still anywhere from 80-95 averages for ACD
Proximity is 0.0 and TSP Color ID: 00
The different tests are rather cool to try, but not helpful in solving my issue...
What I have done: Use a lcd led plasma tv screen cleaner from nexxtech for non streaking. A cloth that came to clean my glasses I have to clean the screen. It is streak free. I have used compressed air to thoroughly blow the area around the upper speaker / sensors and even had the battery out / cover off, etc and blown every hole around the phone.
I still cannot solve this issue of black screening.
The only resolution which leads my ear to "hang up calls accidentally" is to "un check" ie single box, no checkmark, the "turn off screen during calls" option.... ie disable that sensor thing...
I have hard booted, rebooted, cleaned, etc...
Suggestions?
I have the same problem, hoping I won't have to send my device to the service because it's a pain in my country and I will be without a phone for more than a week.
Anyone know any fix for this?

I plan on trying to return mine before re-calibrating via the above technique. Though I would like to hear peoples opinion on if its a calibration issue (i.e they didn't calibrate it from factory properly) or a hardware defect and the sensor it self is bad. My ADC value's when not covered sit at about 70 (clean screen after blowing with air at ear piece) My screen was solid green, wouldn't go white until I blew it out, I didn't check the value beforehand.
Went to Bell today and they will let me exchange it (backing it up now) I checked out the new phone they have for me and its ADC value is 30 with nothing close. From the link above it shows the "normal" value with nothing close to the proximity is around 10, not sure if I should be concerned with the new phone and try and find another if they are willing? Either way its better then my ADC 90 I'm getting today (blew with air yesterday to get it down to 70)
Thoughts? I would love to know a few more peoples ADC values.

It's more then likely difficult to complete without this...
well, I've had this exact same issue, but I read somewhere that if I blow into the earpiece (no air spray, I mean by my mouth, normally blow air into earpiece) it might get fixed. so I did and it is ok now it seems there might be getting dust under the glass through the speaker

I used a can of compressed air... and ADC went form 120 and non working proximity sensor to 10-15 with a good working proximity sensor.
I've contacted the seller where I bought my device (Omegacell somewhere in Alberta... for a SM-N900 imported from some other country)... they told me that if I can reproduce the problem, they will replace my device since I bought the exchange warranty at the same time. So now I'm back to square one... because I got it working with the air through the speaker "trick". Hoping that this fix will last for ever... but if it ever comes back, I hope that it will be within my 1 year exchange warranty.
Deep cleaning
I had the same problem with my proximity sensor. First it wouldn't work at all. Then ,after wiping the screen and blowing (with compressed air and mouth), it would work somewhat. The screen would go black when I put it to my ear but would not come back on after I took it down.
I tested it by dialing *#0*# and using the "Sensor" button. It would sense my hand approaching the sensor but not my hand going away.
I disassembled the phone following the instructions from GalaxyNote3Root.com (Sorry I can't post a link, not enough posts yet).
I wiped the sensor and the inside of the glass with a clean cloth, reassembled and the phone is now good as new.
This might obviously void your warranty, but on my AT&T SM-N900A there are no seals or tapes of any kind that has to be broken to get access. So no warranty voidage. At least no way anyone can tell you the phone was opened as long as you are carefull.
The whole operations takes about 15 mins.
I have replaced the screen, LCD and frame on my VS980 due to dead sections of the screen. There were no problems swapping everything over to the new frame. The phone seemed to be working perfectly until I went into a dark room. When I am in a room with little to no light knock on does not work and if I press the power button the screen times out while I am swiping the home screen. Which component will cause this problem? I double checked each piece before reassembly and everything appeared to be properly installed.
Have you tried the motion sensor calibration? For me i press the power and volume down button quickly and it unlocks. Have you update the touch firmware?
I did the motion sensor calibration and it didn't help. the dialer codes I have found for the vs980 don't get me into the service menu.
I dont know for sure but i think its the hardware problem as in replacing the new LCD and all, but ya that be expensive to buy new ones just after buying a new one. If it still have warranty maybe replacing it perhaps. If the service menu dont work, i dunno.
Your proximity sensor may not be plugged in all the way.
How does the phone work while making a call?
Test it first. If the screen stays on during a call while the phone is held to your face, open it back up and double check all connections.
Unplug and replug the screen, digitizer connections, selfie cam and proxy sensor connections then test again.
The proximity sensor which is top left when looking at the front display. Smush and/or rub with your finger, then try to unlock again. I have to do this frequently.
