Hi, I bought a Xiaomi Redmi 4x yesterday and I can't debug my apps in this device.
I already enabled the Developer Options in the device, switch on to USB Debugging, install the USB Drivers and accepted the RSA debugging fingerprint pop that appears when I plug it on USB port for the first time.
So, I select the "Xiaomi Redmi 4X (Android 6.0 - API 23)" in devices list of Visual Studio, click in Run (or deploy) and see this error:
>Detecting installed packages... >Removing old runtime: Mono.Android.DebugRuntime... >Target device is arm64-v8a. >Installing the Mono shared runtime (debug - 1505313604)... >10% ... 3520kb of 35035kb copied >20% ... 7040kb of 35035kb copied >30% ... 10560kb of 35035kb copied >40% ... 14016kb of 35035kb copied >50% ... 17536kb of 35035kb copied >60% ... 21056kb of 35035kb copied >70% ... 24576kb of 35035kb copied >80% ... 28032kb of 35035kb copied >90% ... 31552kb of 35035kb copied >100% ... 35035kb of 35035kb copied > Deployment failed >Mono.AndroidTools.InstallFailedException: Unexpected install output: pkg: /data/local/tmp/Mono.Android.DebugRuntime-debug.apk >Failure [INSTALL_CANCELED_BY_USER] > > at Mono.AndroidTools.Internal.AdbOutputParsing.CheckInstallSuccess(String output, String packageName) > at Mono.AndroidTools.AndroidDevice.<>c__DisplayClass94_0.<InstallPackage>b__0(Task`1 t) > at System.Threading.Tasks.ContinuationTaskFromResultTask`1.InnerInvoke() > at System.Threading.Tasks.Task.Execute() >Unexpected install output: pkg: /data/local/tmp/Mono.Android.DebugRuntime-debug.apk >Failure [INSTALL_CANCELED_BY_USER] > >Creating "obj\Debug\upload.flag" because "AlwaysCreate" was specified. >Creating directory "obj\.cache\". >Done building project "MyTestApp.csproj". >Build succeeded. >An error occured.

This occurs with all my apps and just in this Xiaomi device. In other brand devices and emulators, the debug works normally.
Just to complement, I have this problem http://en.miui.com/thread-544718-1-1.html and even following the instructions, I can't make the "Install via USB" works.
