The more exterior black wire is thicker than the other ones. You can't really see it in the photos. I am thinking it is the same as the grey wire labeled as ground in the AE pic.
What am I measuring? The white box that clips in is exactly 1cm. All these connectors (which I believe are called JST) with 5 pins are labeled as being "1.25" but I can't tell if that's dimensional. But what else would it be? I can't find any that are 1cm.
I have had the chance to use it on a few different devices and ROMs. Been with it since before name change.
Performance, especially bugginess is highly variable. I don't know if it's the phone, the ROM, other apps, settings or what. Sometimes it is smooth and you forget its there. other times it is crashing every 5 mins, sometimes without being fully recoverable. Like on a certain set up my widgets would disappear when it crashed and widgets aren't in the backup so you have to redo them from scratch.
If it doesn't work on you current device just don't give up on it and whenever you get a new one give it a spin again.
