Repair parts vivo Y21

In this category, you’ll find replacement parts for the 2021 vivo Y21, an entry-level model featuring a Helio P35 processor, a 6.51-inch LCD screen and a 5000 mAh battery. We stock a screen assembly, battery and flex cable in Premium quality, suitable both for anyone repairing their own phone and for repair shops that regularly work on the Y21 and its variant, the Y21s. Before ordering, check the model code, as vivo has reused the Y21 name for very different handsets.

V2111, V2110 or Y21 5G: how to identify your vivo Y21

The vivo Y21 in this category corresponds to model code V2111. You can check it in Settings, More settings, About phone or on the sticker on the original box. If you see a different code, check this list before choosing a replacement part:

• vivo Y21 (V2111): Helio P35, 13 MP main camera and 6.51-inch HD+ LCD screen. This is the model featured on this page.
• vivo Y21s (V2110): the same official dimensions and screen, but with a Helio G80 and 50 MP main camera. The screen and battery listed here are also suitable for it.
• vivo Y21 5G (V2553 and V2554): 2026 model with a 6.74-inch screen and a different battery. It shares the name, but the replacement parts in this category are not compatible with it.

The most common mistake is looking for Y21 replacement parts for the new Y21 5G, or vice versa. They look quite different, but shops and customers often identify them by their commercial name alone. Model code V2111 or V2110 is the reliable reference to make sure you order the right part.

Replacement parts available for the vivo Y21 and how they differ

What to expect from the 6.51-inch screen replacement

The Y21 comes with a 6.51-inch IPS LCD with HD+ resolution (1600 x 720), a 60 Hz refresh rate and a waterdrop notch. It has no in-display fingerprint reader or high refresh rate, so fitting a compatible replacement won’t cost you any panel-dependent features.

The Premium screen assembly compatible with vivo Y21 and Y21s comes with the LCD and touch layer already bonded together, so there’s no need to separate the glass from the panel. It fits model codes V2111 and V2110, which is useful for repair shops that handle both models. As with any compatible part, brightness and white tone may vary slightly from the original panel. Before ordering, check the product listing to see whether it comes with or without a frame. If your phone’s front frame is bent or broken, this will affect the installation process.

What to check on the B-S1 battery

The original Y21 battery has a typical capacity of 5000 mAh, supports 18 W charging and has reference B-S1. The B-S1 5000 mAh battery for vivo Y21 has the same reference and capacity, and is the same cell used in the Y21s (V2110).

Some catalogues list the B-S1 as compatible with additional models in the Y family, and they don’t always agree. The most reliable check is to read the code printed on the battery you’re removing: if it says B-S1, you can replace it directly. Checking the capacity alone isn’t enough, as other 5000 mAh batteries may have a different connector or dimensions.

A flex cable that also fits the Y21s

The Premium flex cable for vivo Y21 and Y21s is suitable for both models, which share the same chassis. Before fitting it, compare the connector and length with the part you’re replacing.

Fingerprint sensor in the vivo Y21 side button: what this means when replacing parts

The Y21 fingerprint reader is integrated into the side power button, not under the screen. This means that replacing the screen does not affect fingerprint unlocking: the sensor is not part of the replacement screen and does not depend on the panel.

If you run a repair shop, it’s also useful to know that the Y21 and Y21s share the same official dimensions (164,26 x 76,08 x 8 mm) and use all three parts listed here. Keeping just one screen reference and one battery reference in stock covers both models. The technical documentation we reviewed does not indicate that the screen or battery is software-paired with the board on this model, although we couldn’t find an official repair manual specifically for the V2111.

Frequently asked questions about vivo Y21 (V2111) replacement parts

Does the Y21s screen work in the Y21?

Yes. The Y21 (V2111) and Y21s (V2110) use the same 6.51-inch HD+ LCD and share the same dimensions, so our screen assembly fits both model codes. The differences between them are the processor and cameras, not the panel.

Are these parts compatible with the vivo Y21 5G?

No. The Y21 5G (V2553 and V2554) is a 2026 phone with a 6.74-inch screen and a different battery. Although it has the same name, its screen and battery are not the same as those in the 2021 Y21.

Will I lose fingerprint unlocking if I replace the screen?

No, as the reader is located in the side power button. The replacement screen does not affect fingerprint unlocking.

How can I check whether my battery is a B-S1?

Check the reference printed on the label of the installed battery. If it says B-S1, it is compatible with the battery we sell. If the code is different, check the product listing before buying, even if the capacity is the same.
