    Nope, I don't mean dead/stuck pixels. Here's what I'm trying to say:

    Bought a Nano, and upon observing the screen to check for dead pixels, I noticed a set of faint dots that make up small squares across the screen (visible at certain angles). I thought, these might be a characteristic of the type of screen Apple is using but then...

    ...I exchanged my Nano due to a defective battery. Long and behold, my replacement did not have any of these faint dots. I also saw my friends' and yes, some of them don't have them and some of them do.

    Apple might be using different supplier of LCD's for the new Nano. Do yours have them?

    Yep, mine has those. I wouldn't have noticed if you hadn't have pointed it out, thanks :p

    NP...I just thought I was going crazy...he he...:)

    To add, I don't think the touchscreen responssiveness is different in between types.

    Mine has the dots. I notice them when viewing in direct sunlight. You say that screen responsiveness is the same. Did you notice any difference in screen quality between the two?

    I didn't notice any screen quality difference between the two. Hopefully it's not just any manufacturing error where that part of the screen is supposed to be installed the other way. Hence other Nano's not having the dots at all.

    The dots show up in specific light conditions. It does this on every touch screen - check your iPhone or iPod touch.

    Cannot find any dots on my iPhone nor have I noticed them on my 3G.

    Wirelessly posted (Opera/9.50 (Nintendo DSi; Opera/507; U; en-US))

    I agree completly with Fuchal. It\'s on all Nintendo DS models, including the DSi that I\'m typing this from, and on the GPS/CD-player in my mother\'s car. It\'s also on my iPod touch 2G and nano w/ touch.

    Not that I am doubting any of you, but my eyes are not keen as some of you guys. COULD YOU PLEASE PLEASE Post pictures of these dots, so I can check on my nano and Iphone 4.

    If you can't see them, then don't worry about them. Really.

    Not to worry about them. From what I can gather, they are a characteristic of the kind of LCD's Apple is using for the new Nanos. They might be there to help with the touch navigation on such a small screen.

    I have gone through 2 Nanos due to defective batteries, and I noticed one that has no visible dots, and upon close examination at my local Apple Store, indeed, some have them and the others don't. This tells me Apple is using at least 2 different kinds of LCD's. There is no difference in quality and responsiveness between the two so you don't have to worry about anything. Then if it bothers you to see those dots, you can just exchange your Nano but you have no guarantees you'll get one without.

    For those who say these dots also exist in any LCD like ones used on iPods and iPhones, this is BS! They are definitely non-existent on my iPhones even upon examination under bright lighting or sunlight. You must have dust under your screens or dead/lit pixels.

    The dots I'm talking about have consistent distances between them (much like the meeting points of the lines on a checkerboard) and are not randomly placed on the screen. I suggest you check again.

    Question, has your third one been good for battery? I just exchanged mine yesterday due to battery (on full volume through my motorcycle helmet the one I had lasted all of 2 1/2 hours. I know it was full volume but it still seems that it should last longer than that).

    The first guy tested the battery and said it was normal (then I went home and decided to play it full volume through my motorcycle helmet just to see how long it lasted. I mean my 3rd gen would last hours and hours doing the same thing).

    I agree with you on the iPhone that is total B.S, as far as the nano go's I'm not sure yet I'll test it more today and see I might just leave it alone but depends how I feel.

    I've noticed that these Nanos do eat up the battery like there's no tomorrow, at least from the 2 Nanos I've had. My replacement now is better but not lasting as long as it should, but I decided to keep it 'cause it lasts me a day and I re-charge it at nights anyway...it's getting better though a bit.

    I also noticed that it takes a few charges before the battery reaches it's full potential so you might want to use your Nano a bit and recharge it several times. :)

    I can see the dots on your pics so this must be a unique situation. Man, I haven't seen those since I had my old 'Compaq iPaq'. :eek:

    As I stated earlier, I do not see them in mine whatsoever but have seen them in the new Nanos.

    Based on the illustration you attached, I'm suspecting the film containing the 'separator dots' has been installed in the wrong layer in some of the LCDs. Hence why we don't see the dots on others and we see them on some.

    Thanks for the pic. :)

    Hrm... maybe so. My nano I just exchanged I could see the dots. I also noticed that if I pressed just enough to open the clip, the whole screen would wave (like when you press on an LCD but I found it odd since it had a hard plastic screen so that should help prevent that).

    I haven't tried it much but hte new one i exchanged for doesn't seem to be as sensitive to me pressing down on the screen (little as I tried it). I haven't checked to see if the dots are there (cannot right now), but I think i'll try when I get home. Maybe the ones that you see the dots it is a mfg. flaw.

    Well, I haven't had a chance on the new one yet but I had gone through three cycles of using up battery and charging fully before I did that test with the previous Nano.

    It's just that 2 1/2 hours won't even last me a day's ride on the motorcycle (and I mean even when you consider that wouldn't be fully riding so the ipod would be off some).

    My 3rd gen ipod so far seems to have the superior battery to both the fifth and sixth (at least the sixth gen has the excuse that the battery has got to be much smaller than the third gen's). It lasted me on my motorcycle a full weekend trip one time. And on normal use (20-30 minute commute on bike a few times a week + walking the dog everyday, the bike it would be full volume) I'd charge it maybe once or twice a week at most. I miss that.

    I have them on my 6G Nano, though they're really faint and I have to look REALLY hard under bright light. I talked to an Apple Genius and this is normal, so no worries... Apple is using the same LCD for every Nano, it's just that some people can see them more clearly.

    Well, I can't see them on my "new" sixth gen nano and neither can I get the screen to get that LCD has been pressed down look on when I press on it to use the clip. Seriously, my old one was only slightly better than my computer monitor about not getting wavy when pressure was put on a point except my computer monitor doesn't have a hard plastic shell over the LCD that should keep that from happening.

    So I think there is more merit to the not together right theory imho.

    This is because the iPod Nano/iPhone screen has a tempered glass cover; most laptops + monitors do not for weight-saving reasons.

    I'm pretty sure they are on everyones but its really hard to see them. Both Nanos in my house have them but you have to hold the nano at a certain angle in really bright light.

    Its nothing to worry about. You can't see them when the screen is on at all.

    The dots are part of the touch screen -- they're the nodes that sense your touches. They are more visible under certain types of lighting (particularly bright sunlight, LED lights, fluorescent lights) and if you hold the screen at a certain angle.
