I was trying to use the Samsung keyboard and it started saying letters that I touched out loud. It wasn't talkback (turned off and disabled). When I switch to gboard it goes away.
It happened once before but went away I think when I restarted but now it's full time and persistent across restarts. I guess I'm going to have to use gboard which I don't prefer.
Does anyone else know about this that has an answer other than it's TalkBack. Because it's not.
In regular Android, there is a setting under "Sound & vibration" called "Dial pad tones". Do you have anything similar?
Edit: Or maybe they broke "TalkBack" in a recent update??
It isn't doing the behavior with gboard.
On the Galaxy there is no "Dial pad tones," but there is a system sound that has a toggle for Samsung keyboard.
It is turned off.
Welp. That was my only guess. Only other thoughts I have involve "force stop" the keyboard app and/or "clear cache/data".
Best of luck tracking this down!
