My iPod nano 3rd Gen has a black line on the screen
As you can see, my iPod nano has a black line. I’m wondering if it’s just a line of dead pixels or the dreaded black spot (which means the battery is expanding).

I'm not sure that the black line is conclusive proof that the battery is expanding. It may simply be a fault such as a loose connector, or a failed component.
The two options you can take are:
- put up with it, but accept that the iPod is reaching the end of its life and eventually the failing display makes the iPod unusable
- find a business local to you that might be bale to diagnose and possibly even repair the iPod. You might find that the cost of repair outweighs the benefit to you
If the casing of the iPod starts to come apart as a result of pushed from inside, that would suggest that the battery is expanding. If that happens, I would take the iPod somewhere that can safely dispose of it (such as an Apple Store).
