My sister has the LG G3 and the next word suggestion isn't working for her.
She installed the Google keyboard and it started working right away.
She would like for this to work on the default keyboard as she misses the numbers and other features.
We're both coming from Samsung phones and it always worked fine.
I moved to a OPO and it isn't working either until I got the Google Keyboard on mine.
If anyone could please share their experience if it's working or not.
