Will everyone please stop talking about different hardware versions?

Serial numbers are not revisions

There's thread after thread after thread about Nexus defects and "311k fixed this but broke that". I've been posting a common response in most of these threads multiple times but it is too much effort to keep doing this.

Now please, all of you do this. Boot into your bootloader and look at your hardware version. It's rev_11, right?

That's because there is only ONE hardware version as per LG's understanding.

So what does 310, 311, 312 mean? Well it looks like month of manufacture doesn't it?! October, November, December?





"But, but, but i've got bigger speaker holes and my buttons don't rattle..."

Sure, manufacturing tolerances mean there will always be slight variances. Devices are built on different manufacturing lines, in different plants, in different countries perhaps - all maintained and calibrated by different teams. This is common. It is impossible (IMPOSSIBLE) to manufacture 2 identical devices. Humans are not good enough at it. This is why all the CPU's are binned between PSV 0-6.. these are within tolerance. Otherwise they'd all be PSV 3, or whatever is thought to be "optimum".

These tolerances mean that there are variations in every single component. No 2 are identical, meaning no 2 Nexus 5's are identical. Technically, every Nexus 5 is a variation. A variation of the perfect one, which probably doesn't exist

All these questions about "If I buy from store x" or "If I RMA now"..... "will I get new version?" Are pointless... there are no newer versions.

The defects reported exist across all the serial numbers. My 310 doesn't have any button rattle. It only rattles the autofocus when I rattle the device from side to side. So to say all 310's buttons rattle and all 311's fixed this is false... and now we have 312's with rattle... what happened? Did LG remove the fix? No! It was never a fix.

It seems some people want to RMA based on their serial number and nothing else or trying to avoid a particular serial... don't. Buy the device normally. If it has specific faults that you're not willing to put up with, RMA it. That's it. Please stop stressing about serial numbers. Buy your device and enjoy it, but please can we try and keep these threads where everyone posts "I've got a 311k and I have x fault" to a minimum? They're not helpful and mean nothing and clog up this forum with nonsense.

I admit the Defects thread may serve some purpose but this is happening there too, meaning the information is tainted.

Further logic

Here's some further logic I would like to include in this post.

The Nexus 5 is not manufactured in batches. It is manufactured 24/7. There is no end of an old batch and beginning of a new batch. The phone that rolls off the production line at 23:59 on October the 31st gets the 310K serial number. The very next phone that rolls off the same line at 00:00 on November 1st gets the 311K serial number.

If a fault had been found in 1 out of every 200 Nexus 5's, where the vibrator motor was faulty, what do you think would happen? Do you think that LG would discard the millions of vibrator motors they have in stock, replace every one with millions more and cease production immediately until the new motor is put in? The fact of the matter is if for every 1 Nexus 5 with a faulty vibrator, there are 199 with a working vibrator, it would be cheaper to repair the 1. What would you do if you were LG? Would you discard 199 good "type A" vibrators and buy 200 "type B" vibrators? Would you stop all of your productions lines and lose money by being unable to service demand? Or would it be cheaper to repair that 1 faulty device with a new vibrator and let the other 199 get manufactured and sold? Would you use up all the old stock of "type A" vibrators until they were gone, knowing only 1 in 200 would be faulty, then when you run out, start using "type B"? I certainly would as that is much cheaper than ceasing production in multiple plants around the world ans scrapping all the good "type a" motors.

In regards to the above, would all "type A" vibrators run out at 23:59 on October 31st, in every plant around the world? Then at 00:00 on November 1st, all "type B" would be used? If you were to scrap all "type A" vibrators and replace them with "type B", would you wait until the next month, when the serial number automatically changes? What would be the significance in that? If you're really going to be bold and scrap them all, you wouldn't wait until the end of the month. if you were happy to wait until the end of the month, then there would never have been a need to scrap them all in the first place. If the bold decision to scrap them ALL is made, you'd do it immediately

If you tightened Quality control, or started adding more glue to hold something in place, would you wait until midnight on the last day of the month to implement it? Why?

If tight rocker buttons and larger speaker holes are a fix and LG have waited to change serial number before implementing the fix, why are there even newer devices with newer serial numbers that do not have this "fix"? If loose rockers are something that needs to be fixed, why haven't all older devices got them? Why hasn't mine?

Great explanation! You had me at "manufacturing tolerances". Everyone wants a perfect device, but humans are not.

I tried to explain this once, but my post got buried so I gave up.

True. Im not happy if my device comes damaged or actually faulty, it will be RMA'd.

Im happy with my device. I don't care about light bleed that I have. It happens

People make imaginary problems with their device and it manifests into some sort of "problem". Damage/faulty = RMA but otherwise they should learn on how to be contented. Google and whoever they partner with is not perfect. Even if they partner with others, still the same result; there would still be some sort of fault/negative side otherwise a very good phone with killer specs.

Good post, think when slightly tweaked version of the same phone comes out i.e bigger speaker holes etc people then think my phone needs to go back for exchange when it really probably doesn't.

Some people won't be happy until they RMA so many devices for b######t reasons that we pay full HTC and Samsung flagship prices for a Nexus. Even still they'll RMA as they probably did with phones from other manufacturers.
