Emu48/Android - Keyboard feedback

[Marco Polo]

I use both real HP50 and emulated on Android phone (Honor 7x).
The emulator works great, but if compared to real calc the interaction with keyboard is really poor.
As a matter of fact user input on emulator is (for me) much slower and error-prone compared to real calc, mainly due to poor tactile feedback.
Same problem for HP48, partially mitigated by better keyboard layout.
Is there any way to improve Emu keyboard feedback?
