I cannot get the red underline on misspelled words to work. Here is what I have done:
1. Downloaded the Google keyboard (kept the Samsung keybaord as my default tho)
2. Enabled spell check
3. Set the input language to "use system"
4. I have turned off the Auto-correction function under the Google KB settings (should this be enabled?)
Any help is really appreciated, not having the red underline has been a petpeave of mine for a long time (I didn't know it was an option).
