Repair HD2, now trouble assembling?

I recently tried repairing a friends HD2, because he had a smashed screen.
I bought the new screen and some 2mm double sided tape. Took the phone apart, and managed to see the lcd was damaged also. Bought one of those then taped the new screen and lcd together using the tape.
The inner chassis had all the old tape on it still, so I bought a new inner chassis. Waited for it, then stuck the new lcd / digitizer to it. The button end didnt seem to stick down that well - even with the new chassis, with the buttons wanting to drop out, and them not sitting out of the screen like they should.
I thought it must be due to the phone only partially assembled, so went ahead and installed the rest of the phone.
Now its together the button end of the phone wont sit in the shell properly and the buttons seem to be lower than they should...
How am i supposed to get this inner chassis to stick properly, and are there any tips or vids to show how its supposed to sit?
thanks.

maybe this video can help you with assembling your phone.
Search on youtube for t8Q7mXdcJ54.

Ive watched that video numerous times, and its a little misleading as to how much is required. Extra tape in places that had to be cut and removed, labels not sticking back down like they do in the video etc.
Im after information as to how people stuck the lcd/digitizer to the inner chassis. I used a new inner chassis with tape pre applied, and it still didnt seem to stick the two things together enough. When you stick the chassis (with lcd/digitizer) into the outer case, it doesnt sit into the case enough, and the buttons are not sitting right.

If u have purchased lcd with digitizer,u could look for flat cable that connects from lcd to mbo,maybe u need to form it.buttons have points to allign,but u need to center both sides in micrometer to function normal.lcd/digitizer frame must have black tape on edges.

done this and still no luck

I have the same problem like foney!
See this:
argh, i can't post my photos! how to do it now, i don't have 8 posts yet!
I've used "3M 300LSE" as a profesional doublesided tape i thought and also put a 2mm stripe below the keyboard, but the display is not really fixed onto the chassi around the keyboard and the keys also can't be used really, because they are maybe not correct centered onto the keyboard circuit board. i've been using the assembly video from htc, but there it's not mentionend very well, how to do it right.

Hmm,last thing i can think is that lcd/digitizer is not properly glued/taped.Did u put pressure for few hours on lcd/digitizer and middle frame?

it is taped on around the lcd using 2mm 3M double sided tape. The chassis i bought new, with tape included. When you stick the lcd/digi to the chassis, it appears that the button end, as l0rdius mentioned, isnt stuck down enough.
The video has the guy "magically" sticking it all together and all going together as it should, but doesnt show any real detail, like showing how things go together to fit properly.
edit/ pulled the phone apart again, and its definitely a case of the tape on the chassis near the buttons not sticking correctly. Ive wrapped it in rubber bands, and used some wooden clothes pegs to try to secure the two better. If it doesnt stick, then I may have to use something stronger than tape, like Tarzans Grip

I've found another thread, in which "profahmad" posted some hints:

Today i've ordered some more 3M 300LSE and want to take a new try on weekend with these hints. Hope i get the display better glued to the chassis and the buttons correctly justified.
Whats about the sticker under the battery. do you guys have problems reassembling it again and again? Or how do you handle it?

Im using glue like in the link if applying pressure for a day or two doesnt work.
I applied a little double sided tape under it, then when i left the phone for a few days with the battery in it seemed to stick down fairly well. Not like factory new, but good enough.

HARDWARE problem,help me ç_ç

at 6:34 the guy touch a copper piece that is glued on a plate.
I've bought an atrix and in my phone that thing is sliced.
it's a big problem?it's front camera or speaker piece?

Hi,
If it's in copper, I think it's the ground for the top PCB.
It's better if you can found a way to keep it connected.
But it's possible that work sliced, it depend of the drawing of the PCB...

it's half conncted..so there would be no problem if a part is connected to the plate?

Put a small sheet of tape to fix it and go head !
It is not a problem for me.

Noise Cancelling Mic

I'm trying to design some cases for the S III and since I'm in the US we don't have the actual phone to look at.
I know you guys do.
Can you tell me if your phones have a tiny noise cancelling mic hole above the flash on the back?
Thanks!

It's directly above flash on the "metal" frame surrounding phone

Is this picture accurate?
I have some 3 cad cam pictures I'm trying to work with...
Here is one link.
http://www.the3dstudio.com/product_details.aspx?id_product=616926
If you click on the 6th image across it shows in high res where the hole is - is this correct?
This one shows it better in blue...sixth image again...
http://www.the3dstudio.com/product_details.aspx?id_product=616923

This is an image of a case - http://www.ebay.com/itm/Genuine-Samsung-EFC-1G6FBECSTD-Original-Battery-Flip-Cover-Galaxy-SIII-S3-Blue-/140767849635?pt=PDA_Accessories&hash=item20c66aeca3#ht_5863wt_952
Made by Samsung, the last picture shows a hole at the top - is that correct?
This makes it even more Bizarre - http://www.ebay.com/itm/280899668071?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_1570wt_1185
This case seems to have holes for both potential places.

Well on mine the Mic is on the very top edge of the phone just a 1mm hole on the metallic band surrounding phone where the very top hole is on that purple ebay case, but my phone doesn't have that hole above the flash on the back cover which is odd because I thought all phones were the same.

It's bizarre. They are all supposed to be the same - I already confirmed that with Samsung last week.
Maybe it's an old image? They could have moved the port I guess.
Does anyone have a picture they can take?

Anyone else?

My white one has the hole in the silver band above the flash, and and no hole in the back cover above the flash

Thanks much.
Even on the Samsung site they have that extra hole. It must be a model design change. But the last thing I need to do is make cases and cover up a mic!

Wobbly and lose s pen tip

I noticed that my s pen tip for the galaxy note 2 is wobbly and loose compared to the s pen tip for galaxy note 1. Any of you having the same issue?
Is that a design or defective part?

Yeah, mines exactly the same.

It's part of the pressure sensitivity.

Does it feel like it might fall out? Like when pulling out of your pocket?

yes me too, but i love the sensitivity of it . very sensitive compared to note 1

I've had a replacement N7100 handset and this second pen has a wobbly tip also. If you shake the pen, can you hear the tip/ spring inside shaking which stops when you hold the tip?

The tip should be loose or else it can't detect the pressure. It won't fall out.

Some galaxy note 1 owners had problems with the tip getting jammed/stuck, and the pen forever thinking they are drawing..
I suspect that's part of the 'loosening' of the tip.

Hi
I appreciate it has to detect pressure but it's as though the nib drops freely out of the pen by 1mm and then when pressure is applied, this 1mm is taken back up leaving the very end part to actually offer and resistance against the pressure. This is the second one I've had (first faulty handset replaced) and i'm almost certain the first S Pen didn't rattle like this one does. It also moves from side to side slightly.

hi, dun want to open a new thread, just a quick question for those who own both note 1and 2
i noticed gn1 pen slot is more secure like when u put the pen into the slot it gives a audible click, while on my gn2, no click only some friction, both pens feel secure when they r in the slot but gn1 one is more solid, is urs the same?

Its normal. I loosened mine and I had to adjust the potentiometer in mine to lower the sensitivity of Airview. It was writing 2 inches above the notepad!

Wireless Reception Issues?

Here's something to think about. The One's casing is indeed 100% aluminum. In every previous attempt by a manufacturer to use an all-aluminum housing the result was disastrous for wireless reception. That includes antenna-gate on the Sensation which only had a partial aluminum body. Looking at the casing HTC's either going to try to get a signal through it or the antennas will have to be forward facing to get through the glass front panel. Neither is a recipe for great and/or consistent wireless reception. It'll be interesting to see how the One does once it's tested by sites like GSMArena and Anandtech.

First of all..I still don't get the "all aluminium construction" as from some pictures the sides are clearly NOT metal but plastic.
Other than that:
His focus on the all-metal attributes is a direct shot at the iPhone 5, which similarly uses aluminum but has a top and bottom row on the back that's constructed of glass, enabling the antenna inside to broadcast and receive signals. The HTC One, however, worked around that by building the antenna into the metal back of the phone, allowing for a more seamless looking device.
While the back of the phone is part of the antenna, Croyle doesn't foresee any reception issues like the iPhone 4, which used the metal frame around the phone as its antenna, causing some signal issues when held the wrong way. Croyle promised there wouldn't be an "antennagate" with the One.

Its mentioned a hundred times on this forum how the antenna is integrated into this phone. The back has strips for it... look at the pictures...

HTC says that the white strips on the sides are in fact metal.

It's no plastic @ the side its all metal....its just metal in a different colour...if u take out all components u are left full metal case so I don't see where the plastic is from

Guess again.
HTC also makes a big deal about the One's all-aluminum chassis, describing it as using a zero-gap unibody design. Indeed, available in hues of black and silver, the handset feels sturdy, has reassuring heft, and its smooth metallic skin exudes high-end craftsmanship. HTC also took pains to point out that while the thin white trim encircling the silver model I manhandled appears to be plastic, it is in fact metal.​

The iPhone 5 needed a lot of glass and the iPad needs the plastic Apple logo for the WiFi and those black plastic strips for the 3g versions. The HTC fans better hope that they need less plastic than Apple or they will have an Asus Transformer prime fiasco here.
The fans better hope that HTC has thoroughly tested this thing from a basement, between two skyscrapers, to a boat, to the top of the mountain, in car, on a helicopter etc. Judging from HTC craftsmanship from the past though, especially button ergonomics, good luck HTC fans.

Oh alright, that's news for me. Very good news in fact

guess they learned what to fix after the fiasco on the one x

That's exactly what I thought of when it was announced the One's housing was all-aluminum. Here's what Anand said about the Prime's signal issues which Asus corrected in the Infinity by adding a plastic strip along the back where the antennas are. Wi-Fi limped along on the Prime but GPS was so FUBAR because of the all metal-back Asus ended up giving owners a detachable external dongle in order to use GPS at all.
There is no RF window on the back of the Prime where the two antennas are located. Aluminum does a fairly good job of attenuating RF signals, which contributes to worse range on WiFi than the original plastic Eee Pad Transformer. WiFi performance at the edge of reception as well as the maximum usable WiFi range are both noticeably lower than its predecessor.​

The One X Wi-Fi issue was caused by connectors not meeting properly during the production process. HTC can't defy the laws of physics which say metal and wireless signals aren't compatible. In the Prime scenario Tomatoes8 mentioned Asus added a second antenna and used diversity as a means of getting a signal through the metal back cover. They also amped the signal up to the point it interfered with BT which uses the same 2.4GHz frequency. The challenge is even greater using metal on a phone because there's less physical space to work with in terms of antenna size, placement, and interference with other components.
For HTC and fans of their devices sake I hope this isn't an issue. But if they succeed in using an all-metal housing and still maintain competitive wireless performance they'll be the first to do so where there’s a history of others failing.

Just another quote/info from Anandtech:
Plastic is injected into the aluminum block after certain cuts are made for the back case, which then gets machined into the final form. The One uses the top and bottom aluminum strips for antennas, both of which are actively tuned to mitigate unintended attenuation from being held. There’s a plastic insulative strip in-between the two antennas and the main body. In spite of being aluminum, the One also includes NFC, whose active area surrounds the camera region. There’s no wireless charging from Qi or WPC, however.

Great info. But one has to wonder with an R&D budget larger than HTC's capitalization why Apple wouldn't have figured the same thing out and avoided the issues they faced when they took the Apple logo off the back of the iPad and moved the antenna under the perforated speaker grate and had to use a plastic trim strip over the antenna on the 3G/GPS version. The only real pass/fail test will be when there are One's in people's hands for a couple of months. It took almost three months (launched in March, issue identified in June) for users to figure out the commonality in the One X's wireless issue. Kudos to HTC if they've figured out how to design a metal device with decent wireless performance where others haven't been able to.
