My mobile phone is ZTE N600+ with full touch screen. Nowadays, when sending text messages, the soft keyboard is often hidden automatically. Why can't I type at all?

Domestic mobile phones and touch screens are really not very good in this respect. Especially when clicking on the rightmost and leftmost keyboards, the response is not sensitive.

It's not the setting, but it really doesn't work. Let's change it to handwritten input.
