Hey guys, I'm quite late but I need the help as well.
I also have the Samsung Transform Ultra and ever since yesterday it started acting up and thinking it's charging every half second as well I wanted to hurry up and nip this in the butt.
My water damage indicator is white, I just tried the screwdriver trick but I couldn't get under the charger so I didn't want to force it in and potentially break something. I don't have a toothpick so cleaning out out wouldn't work and I doubt a q-tip would fit):
Any and all help would be appreciated, I would just get a replacement but I haven't had a plan for a few months, with Christmas coming up I can't really buy a new phone just yet and afford all of the other junk.
