A number of xda-developers members have discovered and confirmed a glitch in the Android 2.3 keyboard that causes double letters to appear after a word correction. The problem has been submitted to Google as a bug, with multiple commenters supporting the submission. As you can see in the video above, the glitch is easily recreated on a Nexus S. This bug only pops up when a word is deleted to be replaced, so it might not be the kind of thing most of us would notice during daily use. But now that I’ve seen this video, it does explain some odd texts I’ve sent with the Nexus S.
Dangit, this is happening to me on my Nexus S 4G that I just got...smh. Creative title by the way :-)
