Vivo V11 Pro In-Display Fingerprint Scanner Explained

The Vivo V11 Pro does have an in-display fingerprint scanner. It uses an optical sensor built into the lower portion of the screen, letting you unlock the phone by placing your finger on the display itself. This article explains how that scanner works, what it feels like in daily use, its limitations, and how it compares to other unlock methods.

Background of the Vivo V11 Pro

Launched in late 2018, the Vivo V11 Pro was one of the first mid-range phones to bring an in-display fingerprint sensor to a wider audience. At the time, this technology was mostly found on flagship devices. The phone features a 6.41-inch Super AMOLED display with a waterdrop notch, a dual rear camera setup, and a Snapdragon 660 processor. The in-display sensor sits under the screen in a fixed position near the bottom center, marked by a subtle fingerprint icon that appears when the screen is on.

How the In-Display Scanner Works

The V11 Pro uses an optical fingerprint sensor, not an ultrasonic one. Here’s the basic process:

• The OLED screen emits light from the pixels above the sensor area.
• That light illuminates your finger when you press on the glass.
• The sensor beneath the display captures a 2D image of the ridges and valleys of your fingerprint.
• The phone compares that image to the stored fingerprint data to verify a match.

Because it relies on light, the sensor works best when your finger is clean and dry. It also requires you to press slightly harder than a traditional capacitive sensor, and your finger must cover the sensor area fully.

Using the Scanner in Daily Life

In practice, the V11 Pro’s scanner is reasonably fast but not as quick as a physical sensor. Typical unlock time is around 0.5 seconds, which is acceptable but noticeable. The sensor works when the screen is off if you tap the display first to wake it, then press the fingerprint area. It also works for authorizing payments and logging into apps, provided those apps support the fingerprint API.

One common issue is that the sensor may fail if your finger is wet, sweaty, or has a screen protector that is too thick. Many users find that registering the same finger multiple times improves accuracy.

Comparison with Other Unlock Methods

The V11 Pro also offers face unlock, which uses the front camera to recognize your face. Face unlock is often faster than the in-display sensor, especially in good lighting, but it is less secure and can be fooled by a photo. The in-display fingerprint is more secure and works in the dark, but it requires deliberate finger placement.

Compared to rear-mounted sensors, the in-display scanner is more convenient when the phone is lying on a table, as you don’t need to pick it up. However, rear sensors are generally faster and more reliable. The V11 Pro’s scanner is a compromise: it looks futuristic but sacrifices some speed and reliability.

Common Problems and Fixes

Users sometimes report the following issues with the V11 Pro’s in-display scanner:

• Slow or unresponsive unlock: Clean your finger and the screen, and make sure your finger covers the entire sensor area.
• Fails after applying a screen protector: Use a thinner protector or one specifically designed for in-display sensors. Some protectors have a cutout over the sensor.
• Sensor icon not visible: Go to Settings > Fingerprint & Face & Passcode and enable “Show icon when screen off” if available.
• Cannot register a fingerprint: Ensure your hands are dry and clean, and try pressing with different parts of your finger.

If the scanner stops working entirely, a software update or a factory reset may help, but hardware failure is possible.

How to Set Up and Use the Scanner

To set up the in-display fingerprint scanner on the Vivo V11 Pro:

1. Go to Settings > Fingerprint, Face & Passcode.
2. Tap Fingerprint and then Add fingerprint.
3. Follow the on-screen prompts to place your finger on the sensor repeatedly until the phone captures enough data.
4. Name the fingerprint (e.g., “Index” or “Thumb”) and finish.
5. After setup, you can unlock by pressing the sensor area when the screen is on or after tapping the screen to wake it.

For best results, register the same finger multiple times, and re-register after any significant skin changes (cuts, peeling).

Security and Accuracy Considerations

Optical in-display sensors are generally less secure than ultrasonic sensors or traditional capacitive sensors because they capture a 2D image. A high-resolution photo of your fingerprint could potentially fool it, though this is difficult in practice. For everyday use, it is secure enough for unlocking your phone, but for sensitive transactions, you might prefer a more secure method.

Accuracy also decreases if your finger is dirty, oily, or if the screen glass is scratched. The sensor area is relatively small, so you need to be precise. If you have very dry skin, the scanner may struggle; applying a bit of moisturizer can help.

Alternatives and Later Models

If the V11 Pro’s in-display scanner doesn’t meet your needs, consider these alternatives:

• Face unlock: Faster but less secure; works best in bright light.
• Rear-mounted fingerprint: Found on many other phones; more reliable but less convenient on a table.
• Side-mounted fingerprint: Integrated into the power button; fast and ergonomic.
• Newer Vivo models: Later phones like the V15, V17, and V20 use improved in-display sensors that are faster and more reliable.

When choosing a phone, consider how you typically unlock it and whether you use screen protectors, as those can affect in-display sensors.

Frequently Asked Questions

Does the Vivo V11 Pro have an in-display fingerprint scanner?

Yes, it does. It uses an optical sensor under the screen, located near the bottom center of the display.

Is the in-display fingerprint scanner on the V11 Pro fast?

It is moderately fast, taking about half a second to unlock. It is not as quick as a physical sensor, but it is acceptable for most users.

Can I use a screen protector with the in-display scanner?

Yes, but it must be thin and compatible with optical sensors. Thick glass protectors can block the light and cause failures. Look for protectors labeled as “for in-display fingerprint” or use a film protector.

Does the scanner work when the screen is off?

You need to wake the screen first by tapping it or pressing the power button, then place your finger on the sensor. There is no always-on fingerprint detection unless you enable the “show icon” feature, which still requires a tap.

Is the in-display scanner secure enough for mobile payments?

It is generally secure enough for everyday payments, but optical sensors are less secure than ultrasonic ones. If you are concerned, use a PIN or password for sensitive transactions.

What should I do if the scanner stops working?

Clean the screen and your finger, remove any screen protector, and restart the phone. If the problem persists, check for software updates or reset the fingerprint settings. If it still fails, it may be a hardware issue requiring service.
