Hi

I am using a LG G2(d802) phone.
I changed the system font. Every things go well, but opera mobile font became strange.

1. English became strange

2. Simplified Chinese became noise text

3. Traditional Chinese works well.

Is there any way to solve this problem? Or other ways to find technique support?
Thanks
