A major Gear S3 feature has been broken in the U.S. for months, Samsung yet to issue a fix (Update)

The issue occurs when a user tries to send a text message through their smartwatch via voice input: as reported by multiple users on both XDA Developers' forums and Samsung's own Community message board, the feature only works a couple of times before starting to display a "Voice input fail" message. Curiously enough, the feature is broken in U.S. English only, leading some users to speculate that Samsung is planning on including Bixby in a future update, and accidentally broke an existing feature in the process of working it in.

We have tested our own Gear S3 unit running firmware version R760XXU2BQC5 and can safely confirm that the problem exists. We have also contacted Samsung regarding the issue and will update the post when we receive a response.

The community has found a couple of workarounds to get voice reply back: one is simply setting the input language as U.K. English, though most people report having problems with speech recognition due to accent differences. The other fix is a bit more difficult: instead of using voice reply right away, users should instead hit the keyboard input button, rotate the device's crown until the last option is highlighted, and then speak.

However, various users have reported both solutions not working for them — for some, U.K. English input also starts failing after some time, while others say the keyboard workaround does nothing. And lastly, the bug doesn't seem to affect Samsung's S Voice app, or when using the device to make phone calls.

Samsung seems to be well aware of the issue, though it has done almost nothing to communicate that to its customers. A company rep has acknowledged the issue on May 1st and reportedly passed it on to engineers, but a fix is yet to be pushed out, three months later. So for now we advise those of you who haven't updated yet to hold on until the bug is patched, though Samsung doesn't seem to be in much of a hurry to do so.

Update: Samsung seems to have quietly pushed out an update specifically addressing the issue, and users are now reporting voice texting once again works for U.S. English. The update bumps the Gear S3's software up to version number R760XXU2BQG4, and the release notes only mention "S Voice - Accuracy and performance improvements."
