I'm glad you were able to resolve the issue by doing that. It's very strange that your device has an error with kanji characters, but none of my tablets seem to have a problem with that.

Hi
I have confirmed that this phenomenon also occurs on other models.
My tablet and 'OPPO Reno5A android 12'.

I will send you an email with the procedure and a link to the data.
The video is long, please watch at double speed.

Thanks
