Vivo In-Display Fingerprint Phones in India: Models & Checks

Vivo has sold more in-display fingerprint phones in India than any other brand, with models spanning from budget V-series and Y-series handsets to the flagship X-series. Before buying any of them, you should verify the sensor type (optical vs. ultrasonic), whether the screen protector is compatible, and the registration and unlock settings in the phone’s menu.

Background: Vivo’s Lead in Fingerprint-on-Display Tech

Vivo introduced the first commercial in-display fingerprint phone in the world, the X20 Plus UD, in early 2018. In India, the company quickly brought the technology to mid-range devices, making it a key selling point. By 2020, Vivo was offering in-display fingerprint sensors in phones under ₹20,000, a feature that was previously reserved for flagships. The technology uses a small sensor placed under the OLED panel, which is why almost all in-display fingerprint phones have AMOLED displays — LCD panels are too thick for the light to pass through.

How the Sensor Works (Optical vs. Ultrasonic)

Vivo phones in India use two main types of in-display fingerprint sensors:

• Optical sensors — These illuminate your finger with the screen’s own light and capture a 2D image through the tiny gaps in the OLED pixels. They are cheaper, faster in most cases, and used in the vast majority of Vivo phones in India, including the V and Y series.
• Ultrasonic sensors — These use sound waves to map the 3D ridges of your fingerprint. They work better with wet or oily fingers and are more secure, but they are rare in Vivo’s India lineup and typically appear only in premium models like the X series or the iQOO flagships (iQOO is a Vivo sub-brand).

You can check which type your phone has by looking at the official spec sheet on Vivo India’s website or the box’s printed specifications.

Current Vivo Models in India with In-Display Fingerprint

As of 2024, the following Vivo models sold in India have in-display fingerprint sensors. This list is not exhaustive, but it covers the most common ones:

• Vivo V29 series (V29, V29 Pro, V29e) — Optical sensor, 3D ultrasonic on the Pro model.
• Vivo V27 series (V27, V27 Pro) — Optical sensor.
• Vivo T2 series (T2, T2 Pro) — Optical sensor.
• Vivo Y100 and Y200 series — Optical sensor on select models like Y100 and Y200.
• Vivo X90 series (X90, X90 Pro) — Ultrasonic sensor on the Pro.
• iQOO 12 and iQOO Neo 9 Pro — Ultrasonic sensor (iQOO is a Vivo sub-brand).

Budget models like the Y36 or Y17s often use side-mounted fingerprint sensors instead of in-display ones, so check the specifications before assuming.

What to Verify Before Buying

When you are considering a Vivo phone with an in-display fingerprint sensor, verify these points:

1. Sensor type — Optical or ultrasonic? This affects performance with wet fingers and screen protector compatibility.
2. Screen protector compatibility — Many in-display sensors fail with thick tempered glass. Vivo phones often come with a pre-applied film protector that works, but aftermarket glass may not. Look for protectors that explicitly state “in-display fingerprint compatible.”
3. Display type — In-display fingerprint requires an AMOLED panel. If a phone has an LCD, it cannot have an in-display sensor.
4. Fingerprint registration — After buying, register the same finger multiple times (e.g., 2-3 times) to improve accuracy. This is a common trick that works on all Vivo models.
5. Software updates — Check if the phone has received recent updates that improve fingerprint recognition. Vivo often tweaks the sensor’s sensitivity in updates.
6. Warranty and service — In-display sensors are glued to the display. If the sensor fails, the entire screen assembly may need replacement. Verify the warranty covers this.

Common Problems and Fixes

Users in India commonly report these issues with Vivo’s in-display fingerprint sensors:

• Slow or failed recognition after applying a glass screen protector — Solution: remove the glass and use the pre-applied film, or buy a protector designed for in-display sensors. You can also re-register your fingerprint after applying the protector.
• Sensor doesn’t work in bright sunlight — Optical sensors can be fooled by strong light. Solution: cover the sensor area with your finger fully and press slightly harder.
• Fingerprint icon not showing on lock screen — This happens when the phone thinks the screen is too bright or when the Always-On Display is off. Solution: enable Always-On Display or tap the screen to wake it before placing your finger.
• Sensor stops working after a system update — Solution: clear the fingerprint data and re-register your fingerprints. If that fails, restart the phone or check for another update.

How to Test the Sensor in a Store

If you are buying offline, do this quick test:

1. Register your fingerprint on the demo unit (ask the staff for permission).
2. Lock the phone and try unlocking with a dry finger, then with a slightly wet finger (dip your finger in water and wipe it on your shirt so it’s damp, not dripping).
3. Try with a screen protector if the store has one installed.
4. Check the unlock speed — it should be under 1 second on most Vivo phones.

Comparison: Vivo vs. Other Brands in India

Vivo’s in-display sensors are generally on par with Samsung’s, but there are differences:

• Samsung uses ultrasonic sensors on its flagships (S series) and optical on its mid-range A series. Samsung’s ultrasonic sensors work better with wet fingers but are slower.
• OnePlus uses optical sensors on most models, and they are often faster than Vivo’s but can be less accurate with dry fingers.
• Xiaomi uses optical sensors on many models, but the placement is sometimes lower on the screen, which can be less comfortable.
• Realme uses optical sensors on its mid-range and flagship models, similar to Vivo.

Vivo’s advantage is that they have been refining optical sensors for longer, so their accuracy and speed are usually very good for the price.

Frequently Asked Questions

Does Vivo’s in-display fingerprint work with a glass screen protector?

Yes, but only if the glass protector is specifically designed for in-display fingerprint sensors. Standard tempered glass is too thick and will cause frequent failures. Vivo phones come with a pre-applied film protector that works, and you can buy compatible glass from brands like GadgetShield or Spigen that mention in-display compatibility.

Can I use a wet finger to unlock a Vivo in-display fingerprint phone?

Optical sensors (most Vivo phones) struggle with wet fingers because water scatters the light. Ultrasonic sensors (like on the X90 Pro) work better with wet fingers. If you have an optical sensor, dry your finger on your clothes before trying.

Why is my Vivo’s fingerprint sensor not working after an update?

Software updates can sometimes reset the fingerprint data or change the sensor’s calibration. Go to Settings > Fingerprint, Face & Passcode, delete your existing fingerprints, and re-register them. If that doesn’t work, restart the phone or check for another update.

Is the in-display fingerprint sensor secure enough for UPI payments?

Yes, both optical and ultrasonic sensors are secure enough for UPI and other payment apps. They are encrypted and stored in a secure element on the phone’s processor. However, ultrasonic sensors are slightly more secure because they capture a 3D image, making them harder to spoof.

Does Vivo’s in-display fingerprint work in cold weather?

Yes, but dry or cracked skin in cold weather can reduce accuracy. This is common for all optical sensors. Try moisturizing your fingers or re-registering your fingerprint when your skin is dry.

Can I replace the in-display fingerprint sensor if it breaks?

The sensor is fused with the display panel. If it fails, the entire screen assembly must be replaced, which can cost between ₹5,000 and ₹15,000 depending on the model. This is why it’s important to use a good screen protector and avoid dropping the phone.
