I accidentally dropped my Gemini into a partially filled bathtub and now several of the keys return multiple characters when pressed. The Q key returns 1 as well as Q.
I haven't, I did have a similar issue, and sorted it myself (tea on/into the keyboard).. bathed in de-ionized water, then IPA.. then when keyboard was still partially annoying, dismantled it far enough to actually wipe the keyboard connector directly with IPA.. that seems to have worked.. Tho the screen could do with more drying out now.
