That's April 4th, right? Just got it today from Sprint, going back tomorrow. Slight gaps under the speaker grills (I could live with that), but the haptic feedback motor was rattling like crazy and there was a stuck pixel.

Also, I can't quantify it, nor can I say it was during normal use since I was also having activation issues, but it felt a little warm...

I still have high hopes for this device! I'll keep everyone posted.

Mine is HT34G...wouldn't that be like last week? They must have literally sent mine from the factory to letstalk and then they shipped them. I got the phone on 4/22 and it shipped on 4/20. So it was made like 4 days earlier in Taiwan? :P

[One (M7) General] hamdir:
I just inspected an HT33M unit, 21st of March

seriously the device is too gorgeous to complain about but it was clearly not the revised build i saw in the HTC33W of my review with almost zero gap speaker covers

perfect screen

the speakers covers are a little micro misaligned, even a fractional micro raised screen from the top, slight imperfections to the outer radius of both speaker and sim eject holes

but really i would accept this unit, if i wasn't around these forums i wouldn't notice a thing, i mean these are micro imperfections

but one thing for sure, revisions came around end of March or start of April
[One (M7) General] ArmedandDangerous:
I think you mean March ;)

Still waiting for units to be sent out locally, within the next week I hear :)

Mine is FA34KW Black

It is perfect so far.....after reading this thread I am tempted to get out the magnifying glass and find something wrong with it:D
[One (M7) General] cnsviet:
I've had this issue too. First it was heard only when calling someone and then it started popping/crackling during the calls. I just got it exchanged today and the new unit seems fine ;)

My old one was from HT made during early April and also had a metal overhang on the bottom corner. The new unit is FA34ES and the plastic part on the bottom right corner protrudes a tad bit more than the metal grill. Nothing major though as this is definitely better than the other way around.
[One (M7) General] trincisor:
First FA346 gaps top and bottom , power button was flush. Bottom speaker grill where the chamfered edge meets the screen in the side was not at the same level , felt like filing it everytime my hand touched it.

Took it back. Got another FA346 evertything is perfect except the navigation button backlight is too bluish. Hurts my eye :(

FA34ES

A few minor flaws, but not enough to warrant me returning it. In my past experience with phones, when you return it for another, chances are the other might have just as many problems, if not more than the previous!

On the top of the phone, there's a slight gap where most people have it, in front of the power button.

http://cdn3.pcadvisor.co.uk/cmsdata/reviews/3427036/New_HTC_One_top_thumb.jpg

On the sides of the phone where the metal and glass meet, there's some excess glue which I could easily peel off, and I did!

On the bottom speaker grill, there's a light vertical scratch.

On top of the top speaker grill, there's a tiny little dot which looks like a tiny scratch or scoff mark.

Finally, to the immediate left of the power button there's a deeper scratch which caused the metal to be raised slightly, and generally the are around the power button doesn't seem too polished.

They don't affect the phone in any way, and not all phones are going to be perfect since they are, after all, made by humans. Sure, it's made in a machine, but the machine was made by humans, and I'm sure people have some part of the manufacturing process. Maybe the phone got scratched during production, etc.

Overall, I know being a flagship phone it should be perfect, but nothing in life is perfect.

When life gives you lemons...

Almost flawless, the upper left part if the screen is slightly lifted.
[One (M7) General] DiZzyBonne:
Reading through the thread, what do you people mean when you say "more yellow whites?" Are you talking about the whites on the screen being slightly more yellow in hue?
[One (M7) General] uh60james:
FA344 received on launch day (Sprint.). Flawless as far as I can tell.

Sent from my HTC One
[One (M7) General] atticus182:
Mine is SH34FW, which means it was produced in Shanghai, at April 15th, 2013.

Which is quite spectacular since I bought it April 24th, and the lady in the store said it arrived the 23rd in the late afternoon.

So that means it only took 8 working days from the factory in Shanghai to the store in The Netherlands!

It's not flawless by the way, but no major gaps either. The black bezel on the top left of the screen is *just* a little (I guess 0,1mm) higher than the alluminium top, which you can barely see but if you slide over it with your finger it feels a bit uneven. Also, there is a slight curve in the plastic on top of the phone, also about 0,1mm where it is not perfectly aligned to the alluminum.

That being said, I only found out these two minor details after closely examining the phone, it's not noticable in daily use so I'm perfectly happy with this awesome phone! :good:

Mine is HT34DW, No defects.
[One (M7) General] puremind:
Three phones, three different color temperatures, three different vibration modules.

Power button: very flat

Gaps: small hairline gap at the top only

Vibration module: very soft, this is clean sound but a bit soft for typing feedback

Display: color temperature slightly on the cool side

White color temperature: 6950K (some meters will incorrectly measure this up to 350K higher, especially if not using the right spectral file for the type of display)

Black Level: 0.37cd/m² to 0.50 cd/m²

Black Level (typical voodoo test pattern): 0.43 cd/m²

White Point: 370cd/m² to 490cd/m²

White Point (typical voodoo test pattern): 435cd/m²

Typical Contrast (without adaptative mechanism): 1000:1

ANSI Contrast: 1100:1
​

Unit 2 (silver)

Power button: protruding a little (easier to feel)

Gaps: gap at the top is smaller

Vibration module: stronger than unit one but a bit untidy/dirty sound on its highest level (e.g. notifications)

Screen: neutral color temperature, slightly lower contrat:

White color temperature: 6550K (some meters will incorrectly measure this up to 350K higher, especially if not using the right spectral file for the type of display)

Black Level: 0.50 cd/m² to 0.64cd/m²

Black Level (typical voodoo test pattern): 0.52 cd/m²

Unit 3 (black)

Fabricated on 12th April 2013 at factory Tierra del Fuego Factory in Argentina (Serial: FA34CWxxxxxx, Panel ID JDI C2_2)

Power button: very flat

Gaps: absolutely no gaps

Vibration module: same stronger vibration as unit two, but more tidy, nice feedback for typing (favorite so far)

Display: Even cooler color temperature unit 1 but same brightness and contrast

White color temperature: 7200K (some meters will incorrectly measure this up to 350K higher, especially if not using the right spectral file for the type of display)

Black Level: 0.37cd/m² to 0.50 cd/m²

Comparison of warmest color temperature on Unit 2 (left) vs. coolest on Unit 3 (right):
[One (M7) General] TRiBaL1981:
Where did you get them from?

Unit 3 seems the best which proves that newer batches are faultless.
[One (M7) General] puremind:
All Amazon Germany. In terms of actual manufacturing yes, unit 3 seems really good but it is not the best. Color temperature is quite cool on that unit.

Unit 1 has the nicer screen.

Unit 2 has the best power button

Unit 3 has the least gap/overhangs and best vibration feedback

Now having both silver and black, I prefer the silver:

Looks more slick (to me) - I like the matte aluminum finish vs. the shiny polished finish of the edges, the contrast between both is superb.

Less vulnerable to fingerprints

Am I the only one who noticed different vibration modules in different devices?
[One (M7) General] gtg465x:
HT34GW here.

A few observations:

Hsinchu, Taiwan factory seems to calibrate white color temperate to around 6500k.

US unlocked and developer editions come from this factory.

Tierra del Fuego, Argentina factory seems to calibrate white color temperature to around 7200k. They appear noticeably cooler.

AT&T versions seem to come from this factory.
[One (M7) General] gtg465x:
I noticed as well. Had an AT&T version and now a US unlocked version (HT34GW). The vibration of the AT&T version was like your unit 1 and the vibration of the US unlocked is like your unit 2.
[One (M7) General] puremind:
I also started to assume that the factory had an influence on the color calibration, however it doesn't appear to be the case, as both my warmest and coolest units come from the FA factory.

Because the color space is almost identical on all units (and they have the same panel ID), this really seems to be a calibration difference rather than a display difference. Still, this is quite a bit of unit-to-unit variation in terms of maximum brightness, contrast and color temperature (15-20%).
[One (M7) General] gtg465x:
Your post says that your warmest unit came from Hsinchu, Taiwan though... unit 2. Both of your cooler units came from FA, right? At least according to your post at 11:55.
[One (M7) General] puremind:
Yes, sorry, I meant to write second warmest. There is a big different between both FA units: 6850K vs. 7650K. It is quite a bit. But both have the same contrast and maximum brightness.

In daily use, the FA units are nicer (e.g. web browsing, outdoor use), whereas the HT unit seems better for films. However, it should be noted that the cooler units can be calibrated to warmer color temperature using the following Android App (since they have a higher contrast to start with!):

https://play.google.com/store/apps/...sMSwxLDEsImNvbS50ZWFta2FuZy5mYXV4ZGlzcGxheSJd

So I would choose the HT units over the FA units.
[One (M7) General] gtg465x:
Your post says your FA units are 7170K and 7650K. Not seeing 6850K. Wish mine was FA as I prefer the cooler screen, but not willing to step down to an AT&T version from unlocked and I feel that if I get a replacement unlocked it will have the same 6500K color temperature.
[One (M7) General] TRiBaL1981:
So the optimal would be something like 7000K.
[One (M7) General] puremind:
The color temperature depends on the measurement device and whether the display and measurement devices are warm.

The 6850K is what I measure with i1 Pro 2 and 7170 is what I measure with Eye One Display Pro. I should have posted the i1 Pro 2 measurement as it is more accurate for color temperature. Will edit this now.

Edit: I have now run all devices through the i1 Pro 2 (spectrophotometer) in succession for better comparison, since as all meters have a slight temperature drift (up to 200K).

Unit 1: 6950K

Unit 2: 6550K

Unit 3: 7200K

Same measured after the meter is warm:

Unit 1: 7000K

Unit 2: 6680K

Unit 3: 7350K

If I measure those same units with the i1 Display Pro (tristimulus color meter), the results will be up to 350K higher.

What device have you used to measure yours? Many review web sites use tristimulus color meters, which all give widly different color temperature readings. tristimulus color meters really can't be trusted for color temperature, even playing with the right spectral profiles, it always come down to the specific type of display being measured, so there isn't even a one size fits all adjustment factor that can be used uniformly across all measured displays.
[One (M7) General] puremind:
Optimal is 6500K, however this may mean slightly lower contrast. I have not seen a higher contrast unit with perfect color temperature yet, but I will continue to monitor this. Also, not only the color temperature is important but what RGB balance is has. A display can be neutral and still have too much green, which is actually worse than too much blue.

Any screen with color temperature up to 7000K is fine. Human vision is quite forgiving in terms of color temperature, especially since perception changes depending on lightning conditions...

Contrast is actually more important.

The HTC One has great color accuracy and gamma, this is what makes the display so great to the eyes of the many reviewers.
[One (M7) General] NxNW:
Could someone please cite an authoritative source that actually says FA means Argentina? People are really running with this and it's based on nothing but assumptions as far as I can tell.

I don't doubt HTC *has* a plant there, but it's not clear to me when we found out FA codes *definitely* came from that plant.

Not trolling- I just got an FA phone. I'm as curious to know what it means as anyone.
[One (M7) General] hamdir:
Google HTC factory Argentina it was announced two years ago
[One (M7) General] NxNW:
No, I did that already, which is why I included the disclaimer

Have we seen the FA code on some other HTC phone already, like the One X or something, that is *known* to have come from that plant? That would be good enough for me.

[One (M7) General] JoeNeckbone:
I'm switching mine tomorrow. Having issues with the digitizer that I touch the home button and it opens the app all the way on right of dock (after a bunch of times of thinking I was hitting wrong spot, I'm positive I'm hitting center of house.) and also a few times top right corner didn't register either. Good thing because screen protector is on best I have ever put one on (not a single bubble). Gonna shoot for a serial with the highest letter they have. It seems like there are good and bad ones from all factories. Any suggestions on best factory to get from?
[One (M7) General] veener79:
Mine is ATT.
[One (M7) General] gtg465x:
If you prefer cooler color temp screens, I would suggest FA. If you prefer neutral / warmer screens, probably a better chance with HT. Though these aren't for sure. Quality control seems to be hit or miss at either factory and it's probably best to get the most recently manufactured.
[One (M7) General] NxNW:
If you want a very recently built phone you may not have to do anything special. Specifically anyone ordering the developer edition through htcdev.com's online store will probably get a very fresh phone if my experience is any indication:

I received mine today just six days after it was built if I am reading the codes correctly. (FA34P ; P = 23 right? And today is the 29th, so six days?)

And it's not like I pre-ordered two months ago and got any kind of priority: I ordered on the 25th. Not sure if they will upgrade everyone's shipping to Next Day Air forever, but for now they seem to be rushing to get these out as fast as they can to buy a little goodwill.

For those who are turning this thread into a display shootout, I will put an i1displayLT on mine later on and let you know what I find. My gut tells me there's no way this thing goes to 400 cd/m2 . But that's why we use instruments instead of our naked eyes I guess. I'm as curious as anyone to see what the measurements will say...
[One (M7) General] omar302:
My phone is an "FA33V" (UK Sim Free), and it was clearly written on the box "Made in Taiwan".
[One (M7) General] NxNW:
Um, by your logic a phone with a serial code beginning with SH must be packaged in a box labeled "Made in China".

I think it's far more likely every HTC One comes in a cardboard box printed with the words "Made in Taiwan" regardless of what factory made the phone placed inside it.
[One (M7) General] omar302:
You do realize that what your saying implies that HTC is providing false information to Customs authorities (& customers)? I wouldn't believe that HTC would do such a thing.
[One (M7) General] Tower1972:
Looks like mine is HT32EW..whatever that all is...the thing is..with the Zero Gap construction..I watched a video of a drop test..the HTC one was dropped, and the bottom speaker cover (mine has small gaps on top AND bottom) popped off..I didnt get a chance to see what it looked like after that cover popped off, but with everyone worried about dust etc getting in there...it looks like its only going to get it, if at all..inside the speaker compartment..not in the screen itself as I believe that is a seperate sealed part of the phone
