I am using Mi Note3, before that, I can run the code from react-native using react-native run-android and connect with my phone. Now cannot already. My MIUI version is 10.2, I already open Developer options, USB debugging, Install via USB and turn off the MIUI optimization.
This happens when you try to update a signed release build with a debug build for instance. apk cannot be installed because its signature is incompatible with the currently installed version.The solution is to uninstall the existing app from the device.
