    I found a rubber plug under the battery cover that covers a small diode. Why did they cut a relief in the metal bracket over the diode and make an access port covered by a rubber plug? All for one little diode?

    Just curious. Pics below:

    by the way, for anyone reading this, i think that because of the lack of the contacts under that little rubber boot, we cannot use the revolution touchstone back and pad on this phone.

    Maybe it is an induction circuit for wireless charging and not just a diode . somebody has to know if it can be used?

    There's a little sticker that turns red if it gets wet that is used to check for water damage.

    LG Revolution service manual shows contacts that look just like the battery contacts, in that spot. which i assume interface with the touchstone cover. the fact that the touchstone cover is thicker than thestock one, i would not expectthem to be able to integrate the charging system into the phone.
