There's no real way of knowing without firing it up and taking a look. I'm guessing you don't really want to do that because you might want to sell the newer one as "new". Bear in mind that i've seen a few items on ebay that are sold as "new" where the seller has explained that the box has been opened but it hasn't been "used" i.e. taken out and about/used as a smartphone. i.e. it was only checked. This way it's *possible* you'll still get a good price for it if you decide to open the box of the new one to take a look. Just a thought - obviously it's up to you.

---------- Post added at 10:49 AM ---------- Previous post was at 10:41 AM ----------

OK replying to my own post for continuity. My third N4 arrived today. Same as previous (two probably) with a 301K SN and lo and behold this one also has screen "issues". This time the lower third of the screen is affected again with it having a subtle but noticeable yellow "tint" and also - interestingly - it looks brighter than the top half of the screen. On an app with a white page like chrome or the email app (good one to use to check) you really can see that the bottom is very slightly more yellow and quite obviously brighter.

Now I've been googling this to death and the results are inconclusive but it *may* be that this will improve over time as these units are clearly fresh off the runway and it's possible that it's the glue waiting to "cure" and therefore the screen may even itself out. It is possible however that the brighter bottom third/half is due to backlight bleed or some other variance with the LED backlights. Again this could be due to the curing process and the position of the screen may change subtly with time. I have no idea.

I could get yet another replacement sent out but there's currently a hold of £837 on my account for 3 phones and a fourth would take it to £1116 which seems excessive.

Is anyone else here having issues with the screen uniformity? I'd be really interested to see if others notice this and if so - does it improve/fix itself with time? There's *lots* of info regarding "spots" and yellow tint for the HTC One X but not so much for the N4. Are there any batches that are free from this issue?

Thanks!

MediaMarkt gets different stock as google, so their availability has nothing to do with situation with play store.

As to the production codes, LG does seem to have certain "back and forth" of serial numbers. So it can happen, that they assigned some ranges of the serial numbers in the last days of december and actually produced them several days later in january.

211K, it was purchased some time in December by its previous owner. It's a revision 10 model from Australia.

Not noticed anything, except that the images when digitally zooming end up a bit pixel-liney. But, hey, that's digital zoom. Digital zoom was a bit softer on my previous One X, whereas this seems to have a sharper digital zoom.

It´s somehow weird because I got a 301K (produced 14.1, bought in Media Markt Germany ) phone with HW_Rev 10 !!! and a small Camera opening. What the f**** went wrong ? :(
[Nexus 4 General] VivaErBetis:
It may be strange, but possible. Read this document:

http://xdaforums.com/showpost.php?p=37120904&postcount=42516

As you can see rev_11 means that PCB has been replaced to correct a wireless charging problem. The change of the back cover is unrelated to hw revision.
[Nexus 4 General] Klin03:
Thanks but does this mean that all other changes are included except of the new PCB ? Because i have to mention that i´ve not found any bug people are talking about like the scratching in the corners or the loud autofocus,although the autofocus bug has been fixed afterwards.. I must admit that i´m still a litte bitte confused ... :rolleyes:
[Nexus 4 General] VivaErBetis:
The only thing I have for sure is that rev_11 means that PCB is different. Any other of the described and supposed changes may be or may be no included in any revision (as you, for instance, have a rev_10 with small camera cut and who knows if something else).

With respect to THIS link, does it mean they actually changed some hardware part(s) whcih weren't working fine?

What was LG's R&D doing before launching the device? And what about rev_10 customers now? I have read people say LG/Google won't change the phone depending on rev version but they have changed the hardware because rev_10 must have had some issues? So why not replacement for customers who got rev_10?

I'm also curious what the other three letters mean.
[Nexus 4 General] Alexander T.:
No idea, but most probably they identify the exact factory, otherwise, it is just an internal code.
[Nexus 4 General] negroplasty:
210K here and she's a beauty :D
[Nexus 4 General] draugaz:
They need to encode the the exact model number anyway.

Pity I currently have no access to the box of my Nexus4, but this got me interested so I dug out some unboxing videos on youtube with some serial #s and IMEIs.

As we know, first 8 IMEI digits are so called TAC (Type Approval Code) describing the exact phone model and issued by external regulating body, so manufacturer can't change it at random. It can of course request as many codes as it wish.

Video #1:

210KPKN044861

35391805-044861-n

Video #2 published Nov 29:

211KPGS094999 (16GB USA model)

35391805-094999-n

Nov 16, 16GB USA:

210KPJP020796

35391805-020796-n

And another one on Dec10 16GB USA:

211KPLC....

35391805-151...

My own Nexus ordered Dec4, sent out Dec5 (16Gb German model)

also has IMEI 35391805-109....

And another one with 212K.....165....

Which would mean:

Phone produced in Oct had serial#

20000 USA

45000

Nov

95000 - USA

110000 - GER

150000 - USA

DEC

165000

Still the same TAC.

Would be interesting if people could check their IMEIs, if they begin with 35391805 (for 16Gb) and then post the hunderds and tenths thousands of the serial number (ninth and tenth digits following after "05") together with date of shipment and country modification.

This could help to estimate, how many TACs google have "used" until now and how many devices have they produced in total.

Currently it looks like LG managed to produce something between 50 and 100k units in November. Ok, this probably was a "ramp up" month busy with other devices they were preparing for christmas. Would be interesting to see the other TACs (if any) and sequence numbers.

If this is the only TAC, it would mean they have produced only about ~200k devices to date.
[Nexus 4 General] heynomi4u:

[Nexus 4 General] draugaz:
Does you IMEI begin with 35391805... and what the next 2 digits are? Is it an USA model?
[Nexus 4 General] jundii:
211K here. Only small issue I have is the IPS screen has some light yellow bleeding at the top. I can only see it on a black screen in low light.
[Nexus 4 General] draugaz:
Sine noone is posting excerpts of their serial numbers, back to the stupid youtube unboxing videos:

212KPGS180447 16GB canadian, matching IMEI TAC.

212KPBF26399.... 16Gb german model.

353918, rest is covered by finger, but I suppose this is still the same TAC.

So we get December and device #264000. Which means - at least 100000 devices in the first 2 weeks of December.

I can confirm this because I got mine 211K device earlier this month from GPlay.

via Google Nexus 4
[Nexus 4 General] xdatastic:
what hardware version does it say in the bootloader for both?
[Nexus 4 General] draugaz:
Ok, which brings us to following:

Phone produced in Oct had serial#

20000 USA

45000

60000 AUS

Nov

92000 - USA

95000 - USA

109000 - GER

110000 - UK

132000 - USA

138000 - USA

150000 - USA

DEC

165000

264000

So, they did produce at least 60-90K devices in October, 60-100K in November and 100K+ in December, still counting (just 16G devices).

I am mainly doing all those calculations to understand what is really happening, i.e. how big was an initial stock and is the google doing something to ramp up the production (there was an conspiracy theory, that google is deliberatly throttling the availability to produce hype).

So, given the mid November launch, we would get something like 100K 16G devices prepared for launch (for all markets).

Then I suppose it took at least a week after launch to source all the components and resume production which could add 1-2Weeks of idle time in Nov and correspondingly less units produced.

What would be insteresting, if someone has a 16G 210K device with

353918-05-xxxxxx-x with xxxxxx greater than 06xxxx

or 211K with lower than 09xxxx

This would help to better estimate the october production counts (and initial launch stock).

Nov-Dec cut off is reasonably well known somewhere withing 15k devices.

It would be also interesting to know if someone has a 212K device with 353918-05-xxxxxx-x where xxxxx is greater than 26xxxx, so we know production counts for Dec.
[Nexus 4 General] derPianist:
211K PlayStore Device: HW_rev10

[Nexus 4 General] draugaz:
Wow, this is very interesting. Does the IMEI begin with 353918-05-xxxxxx-x and what the first 2 xx are?

Very strange. This would indicate, that LG is unable to produce enough sparking backs and google is desperate enough to cut corners.

But I don't know how they are planning to get away with this. I mean, your girlfrend is certainly less than amused and they will probably get a lot of returns.
[Nexus 4 General] derPianist:
It begins with 353918-05

[Nexus 4 General] draugaz:
Weird. My own (german) nexus which I got from second Play store batch (Dec4) also has an 353918-05-109xxx, but it is a Korean rev10 device.

Almost sounds like LG started the second production line in their China factory, but IMEIs are assigned by some central server, so they can interleave.

Otherwise it would mean, that IMEI assignment is not strictly sequential and allows no statement about production counts.

[Nexus 4 General] draugaz:
Don't act like you was born yesterday :)

There is no gadget on earth which remains in the same hardware revision over its complete life cycle. The same applies for any non trivial product like cars, TV's etc etc.

Every manufacturer finishes their QA process believing they caught all relevant bugs and then start producing millions. Everyone knows it is physically impossible to find each and every bug, only because there is a huge difference between manufacturing several hundreds of preproduction units and millions they will be churning out in the mass production.

After the devices are out in the wild, customer feedback starts to pile in. Manufacturer tries to fix them, something is possible via software (like button problems in Samsung Nexus Galaxy) and something requires hardware changes. So, several months into the production there usually are new hardware revisions.

Then there is the whole bunch of another boring reasons like "supplier X was unable to deliver us enough of their XCV234 chips, so we went to their competitor Y and ordered ZZZ0785r which is the same but different, so we need to reroute that circuit 2mm to the left".

You just usually don't have a slightest idea of all of this and don't worry about nothing.

In other words: if you have a particular problem - do ask for replacement. If not, then simply enjoy your device.

Either back your claim or STFU.

Moreover, as per you, if u r from one of the very first batch's customer, u r basically a testing purpose for Google/LG? You spend $ 400 to test a device for them and in the end get to know u have been cheated in hardware and that the phone u have does not possess XYZ quality/feature?

Sir, don't be a d*ck and respect others customer's money and time they spent to get hold of this device. For the confidence they showed in Google and LG, they should at least be given a chance where their hardware is warrantied.

And FYI, I already own a rev_11 phone and I am pretty much happy with my device's Hw_Rev. But I still care for those who got rev_10 units.

[Nexus 4 General] draugaz:
What would you like from me as a backup?

Yes, you are. That's why you should not buy a phone in its first three or four months if you don't want to be an early adopter. And by the way, the same goes for pretty much anything nontrivial, not only electronics.

So, what you basically say, manufacturers should just discontinue model X and then start differently named model Y for a next revision? So the buyers of X would not feel being cheated?

You did not pay the kind of money warranting such changes. Such a nexus4 with "latest HW revision guarantee" would easily cost over 1000$.

I have got a REV_10 unit.

And by the way, rev12 is comming and rev13 after that and so on. So you can already prepare your RMA request.
