Samsung a9 sends text messages in split screen, why is the keyboard full screen? What's the point?

The full keyboard input method interface can display letters and numbers at the same time, and there is no need to switch to the digital input method interface separately. To switch the full keyboard input method, please operate: Settings-Language and Input-Click the gear icon on the right side of Samsung Chinese input method-Keyboard type setting (/input language), taking Chinese as an example-Select "Full Keyboard" (Qwerty keyboard). To switch the Samsung input method of mobile phone to Jiugongge mode, please operate (taking Chinese as an example):

1. Settings-Language and Input-Samsung Keyboard (Samsung Chinese Input Method)-Chinese -3*4 Keyboard.

2. Settings-Language and Input-Samsung Chinese Input Method-Click the gear icon at the back-(Advanced Settings)-Keyboard Type Settings (Input Language)-Chinese-Select "9-key Pinyin".

Tips: The operation paths of different models of mobile phones may be slightly different.
