Keyboard not show at Samsung galaxy s22, note 20, a52s


Mblock is good app to teach program to students at my school. But, this year i met some problem at students who use Samsung smartphone like galaxy s22, note 20, note10, a52s.
The problem is that keyboard is not activated when need to input text. Most students use well this app. But a few students can’t input text because keyboard doesn’t show up.
