google 輸入法

I havce installed Google 粵語輸入法 in 2 device,
1. LG old phone (andorid 4.0 4)
2. Acer Tab .

my Phone is using this without any problem, when I type english wording, 'Fri',then it can auto show me 'Friday' ' Friend' choice.

But when I just installed in Acer Tab andorid 5.0, it cannot show any similar english wording.

anyone have idea?

it is my setting in Tab,all english setting is enabled..thanks

Google Cantonese input method settings -> input -> check all the box at the bottom of the page (under English) ?
