What is a DPC App?
DPC stands for Device Policy Controller — Android's official enterprise device management framework, built into every Android phone since version 7.0 (Nougat, 2016). When you install a DPC app and grant it Device Owner permission, the app gets root-level control over the device's policies — kiosk mode, lock screen, app blocking, factory reset protection, and more.
EMI PRO's DPC app is the same core technology used by Google for managed Android Enterprise devices, but specialized for the Indian device finance market. It runs silently in the background, sends a heartbeat every 30 seconds, and instantly executes lock/unlock commands from your dealer dashboard.
DPC Modes Explained
Device Owner Mode (Strongest)
The DPC owns the entire device. Cannot be removed without factory reset, and even after factory reset, FRP (Factory Reset Protection) requires your authorization. This is the strongest lock mode and is set during initial provisioning via QR code or USB.
Profile Owner Mode (Work Profile)
The DPC owns only a managed work profile. The customer can use the rest of the phone normally. Less powerful but easier to set up — works on any Android phone without a factory reset.
LITE Mode (No Special Permissions)
Fallback for older Android devices or quick setups. Uses Accessibility Services + Device Admin to enforce lock. Customer can theoretically remove it, but EMI PRO detects removal attempts and alerts you instantly.
Setting Up the EMI PRO DPC App
Method 1 — QR Code Provisioning (recommended)
- Reset the customer's phone (or use a brand-new phone)
- On the welcome screen, tap the screen 6 times in the corner
- Scan the QR code from your EMI PRO dashboard
- Phone auto-installs DPC app, grants Device Owner, connects to EMI PRO server
- Total time: 3-5 minutes
Method 2 — USB / ADB
Connect the customer's phone to your computer via USB. Run the EMI PRO USB tool. The DPC installs and gets Device Owner permission via ADB command:
adb shell dpm set-device-owner com.emipro.deviceservices/.AdminReceiverThis works on any Android phone, no QR needed. Takes 2 minutes.
Method 3 — APK Sideload (LITE mode)
Download the APK from /download, install on the customer's phone, grant Accessibility + Device Admin permissions. No factory reset needed, but lock is slightly weaker (LITE mode).
