Blink Setup
This guided setup unlocks additional Blink features using a
one-time USB connection from your computer. Nothing is sent to a server —
everything runs locally. All steps are optional.
What you'll unlock:
Screen Protection Service — Blink detects when a protected app opens and covers it instantly, before any content appears
Auto-Recovery — silently re-enables screen protection if a phone update ever turns it off
Banking Mode — automatically pauses screen protection inside banking apps so they work without any issues, then restores it when you leave
What you need: a Windows or Mac computer with Chrome or Edge, a USB cable, and your phone nearby.
Enable USB Debugging
USB Debugging lets your computer talk to your phone over the cable.
This is a temporary setting — you can turn it off after setup is done.
Open Settings on your phone
Samsung phones: tap About phone → Software information Other Android: tap About phone
Tap Build number 7 times — you'll see a message saying "Developer mode has been enabled"
Go back to Settings and open Developer options (usually near the bottom of the list)
Turn on USB debugging
Plug your phone into your computer with a USB cable
Your phone will show a popup: "Allow USB debugging?" — tap Allow Tip: check "Always allow from this computer" to avoid being asked again
If you see a USB notification on your phone, tap it and select File Transfer (MTP)
Used Android Studio or ADB on this computer before? You'll need to stop
the ADB server first — otherwise the browser can't see your phone.
Open a terminal and run: adb kill-server
Connect Your Phone
Click Connect via USB below. Your browser will open a
device picker — find your phone's name in the list and click it, then
click Connect.
Don't see your phone? Unplug and replug the cable, make sure USB Debugging
is still on, and check that your phone's screen is unlocked.
Waiting for connection…
Connection Troubleshooting
Try these steps in order:
Unplug and replug the USB cable
On your phone, pull down the notification bar and tap the USB notification — select File Transfer (MTP)
Check that USB Debugging is still enabled in Developer Options
On your phone, look for an "Allow USB debugging?" prompt and tap Allow
Try a different USB cable or port on your computer
Advanced: if you have ADB installed on your computer, you can run these
commands directly in a terminal instead of using this page:
# Release build (com.factor.blink) — use this for production:
adb shell pm grant com.factor.blink android.permission.WRITE_SECURE_SETTINGS
adb shell settings put secure enabled_accessibility_services \
com.factor.blink/com.blink.intercept.BlinkAccessibilityService
# Debug build (com.factor.blink.debug) — use this for development:
# adb shell pm grant com.factor.blink.debug android.permission.WRITE_SECURE_SETTINGS
# adb shell settings put secure enabled_accessibility_services \
# com.factor.blink.debug/com.blink.intercept.BlinkAccessibilityService
Grant Permissions
Your phone is connected. Grant each feature below — all are optional, skip anything you don't need.
Auto-Recovery
Free
Silently re-enables screen protection if a system or OEM update ever turns
it off without warning. Also required to enable Banking Mode below.
Recommended — grant this one first.
Screen Protection Service
Free
Lets Blink detect when a protected app is opened and cover it instantly —
before any content appears on screen. Without this, Blink uses a slightly
slower fallback method.
Banking Mode
FreeGrant Auto-Recovery first
Automatically pauses screen protection while you're inside a banking app
so it works without any compatibility issues. Protection turns back on
when you leave the banking app.
You're all set!
Setup complete.
A few final steps:
Unplug the USB cable from your phone
Optional but recommended: go back to Developer Options
and turn off USB Debugging — it's no longer needed and
turning it off is good for security
Open Blink and trigger it with the volume sequence to confirm everything is working
To configure Banking Mode: open Blink → Protected Apps → tap the 🏦 icon next to each banking app you use
