This error means the installation was cancelled on the device. Here’s what you can do in simpler terms:

• Check for Prompts:
  Make sure you didn’t accidentally cancel an install confirmation on your device. Sometimes a pop-up appears asking if you want to allow the installation—tap "Allow" if you see it.

• Enable Developer Options:
  Ensure that USB Debugging is turned on in your device settings. Also, if available, enable "Install via USB."

• Disable MIUI Optimizations:
  Xiaomi devices sometimes have extra security. Try disabling MIUI optimizations in the Developer Options.

• Allow Unknown Sources:
  Check your security settings to ensure that installing apps from sources other than the Play Store is allowed.

I hope these steps usually resolve the [INSTALL_CANCELED_BY_USER] error.
