I've tried to install the application on Xiaomi Redmi 9 for the first after tring it on the emulator which worked fine but when I tried to install it on the physical device this error appeared The application could not be installed: INSTALL_FAILED_VERSION_DOWNGRADE
Before installing a popup message said to uninstall the existing app, but I've searched on the phone everywhere but there was no app installed.
I tried to install another application on the same phone it worked fine with no error, I've no idea how to deal with this problem.
I need your help and thank you in advance.
