I know it's me who's raising about this issue again. Regardless the android version, phone model, and apps, Chinese typing lags hugely while taping on the suggestion on the prediction bar. It takes one or two seconds to get the suggestion typed into the text box. It happens since the 5-language support, which means it has been 4 or 5 months. Some users and me made several reports during this time but we heard absolutely zero fix or underway news.
This feedback is also included in my report article to the team, and this should happen now, we waited for too long.
Bon courage team!
