问题
I know this is an old question but I am trying to install my app the very first time on Redmi note 4. Whenever i try to install it displays a dialog saying..
Installation failed with message Failed to establish session. It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing. WARNING: Uninstalling will remove the application data! And it gives error after this.
This app is not installed before,I have cleared cache,rebuild the project,restarted my phone but nothing is working.

I'm Using Redmi Note 4 mobile (Xiaomi Phone). I got the same problem.
Problem Resolved:
Go to setting >> Additional settings >> Developer options >>Turning off MIUI Optimizations
and also turn on USB debugging and install via USB. And then restart your phone. After that, I am sure that your problem will be solved.

I didn't have to turn off MIUI optimizations (using MIUI v8.5.3.0 MAGCNED). In my case I was blocked by the MIUI security system.
Go to Settings > Additional settings > Developer Options
- Turn ON USB Debugging
- Turn ON install via USB
- Turn OFF Verify apps over USB.
Once you do this MIUI will prompt you whether you want to install your app. You only need to accept permission once.
One strange issue I notice is that I cannot enable install via USB without sim card. However, Once it is enabled I am able to remove the sim.
回答5:
The latest version of Android OS will have multiple user logins like admin and guest, whenever we install an app through USB debugging, that .apk file will be installed for all users in the mobile, Uninstall the .apk file from all the users including guest login.
回答6:
- Turn off Developer Option
- Restart your mobile
- Turn on Developer Option
- Turn on Usb debugging
Worked for me. Hope it works for others...
回答7:
This issue occurs sometime I have also faced the same issue.
Try the following steps
Go to Settings > Additional settings > Developer Options
Off your Developer Option and re-On it
On - USB debugging
and press Revoke USB debugging authorization
I hope it will work.

In my case Faced the Same Issue with My Redmi 3s PRIME and I can't able to enable the Install Via USB and it asks to connect Network So I tried the Following Method and luckily it works...!!
Open Inbuilt Securit App.
Click On Optimize. (While Scanning, It Disables the Developer Option )
Now Open Settings->About Phone-> Tap On MIUI Version to Enable the Developer Option
Open Additional Settings -> Developer Options.
Now Re-enable the USB Debugging it automatically enables the Install Via USB
In Android Studio Disable Instant Run Settings>Build, Execution, Deployment>Instant Run
Now Run the App with Android Studio.
