Yes, automatic spell check is on, my phone says Im using a Samsung keyboard, not Google keyboard.
Thanks for screenshots,
I tried to include screenshot,
But just like everything else here with my phone I was unable.
.. I took sc shot of my mood error code (does not give choices, only white box without choices, because page says, "plug-in not supported".

-----> Btw, red highlight for misspelked words shows up everywhere else (when using my phone), just not on this forum...

Lol. Not intentional but I just mispelled misspell...letter k is to left of letter l on this keyboard...

My shaky hands, blurry tired eyes, and this dumb new phone with a very difficult keyboard to use, are causes.
Right now my hands arent shaking, my eyes are clear, have glasses on, but phone's keyboard still impossible for me to use...

I had a galaxy4 for years, and we got along well...
Got this Galaxy 7 in March from Sprint store in Mays Landing, NJ.
The sales person REFUSED to set it up (like they ususally do for you...and Ive been struggling ever since.!!

My life was a horror before needing a new phone (last one lost or stolen, most likely stolen)...
Struggling with the most simple basic things non-stop.. Only reinforces what I already knew, when I found this site= MY LIFE IS HOPELESS.
