That “ME“ number looks like an Asus model number. Maybe within Asus, a Nexus 2B (this one) is known by that number within Asus?
(2017-11) My speaker at the camera end sounds raspy when loud. Maybe the “cone“ has a crack, or has partly detached from the voice coil…
You might see a black fabric tab attached to the battery connector. Try pulling on it to disconnect! Sweet.
Do be careful when prying: The micro USB connector shell extends through the back, so pry the other three edges free, then unhook the connector edge. I disabled my connector by forgetting this. :=(
I think you meant “copper”. So sorry to tell you, but the connectors are ZIF, which clamp the removable item in place, like removable CPUs on motherboards. The black plastic strip is the clamp. To unclamp, lift one edge. It will have definite friction. I’ve forgotten which edge, though. The black plastic is strong, but relaxes with time and fails to clamp across the whole width.
When that happens, your sensors go dead (and maybe the mic. as well?).
You'll note foam pads on the back cover which were to help clamp,but they’re much too soft! Small-cell polyethylene foam might work. I need to fix mine. Hope this helps!
