I have GTA vice city game in my mobile (Redmi Note 4 running on Nougat and MIUI 9). I have installed and started playing but as you all know the game is not fun without "cheat codes".
So I want to use an onscreen keyboard with which I can type in the cheat codes to play the game. I've already tried the third party keyboards but my phone doesn't give permissions for the application.
How can I achieve my goal?
