The short answer
A Vivo Y31 cover only fits the phone it was cut for, and there are three Y31s. The Y31 5G (2025) is 166.1 × 77.0 mm with a 6.68-inch screen, 2.2 mm taller than the 2021 Vivo Y31, so an old Y31 back cover or flip cover won't fit it. The Y31 Pro 5G has a different screen and camera layout, so a Y31 5G cover won't fit the Pro either. Check Settings → About phone and order the cover listed for that exact name.
Vivo has sold three phones called "Y31" in India: the original Vivo Y31 from January 2021, and the Y31 5G and Y31 Pro 5G, both launched on 15 September 2025. The Y31 5G is the one in shops now, but a search for "Vivo Y31 cover" still turns up back covers and flip covers made for the 2021 phone. Those don't fit. Picking the right mobile cover for Vivo Y31 starts with knowing which of the three you own.
Cut for the Y31 5G body and its tall camera island. Closes over the screen, holds 3 cards and cash, and folds into a stand.

The three bodies differ by only a couple of millimetres. That's why the wrong cover feels almost right, then won't close.
Bars start at 150 mm so the gap is visible.

What to check on a Y31 5G cover
1

3
- Camera cutout. It should frame the whole pill island, ring light included, with nothing touching the glass.
- Stitching. Even tan topstitching runs along every edge and holds the panel in place.
- Denim weave. Denim hides small scuffs and softens with use.
Vivo Y31 back cover or flip cover?
- carry the phone in a pocket or bag with keys
- want your cards and some cash with the phone
- watch videos and want a stand
- want the slimmest phone in the hand
- mostly use a mount that grips the phone's edges
- want the Rose Red or Diamond Green back on show
Three Y31 cover myths
MythAny Vivo Y31 cover fits the Y31 5G.
FactThe 2021 Y31 is 2.2 mm shorter and has a different camera block. Its cover won't close over a Y31 5G.
MythThe Pro is the bigger phone, so its cover will fit a Y31 5G loosely.
FactThe Pro has the bigger screen, but the Y31 5G body is bigger: 166.1 × 77.0 mm against 165.7 × 76.3 mm. The cameras sit differently too.
MythA back cover keeps the screen safe in a drop.
FactA back cover leaves the 6.68-inch display open. A flip cover closes over it. More in flip cover vs back cover.
Colours and price
Every cover is a denim upper with a tan PU leather trim, a side magnetic strap, a black inner tray and an inside flap with 3 card slots and a cash pocket. Four denim shades are ₹599; Forest Green is a chambray weave at ₹699.
Frequently asked questions
Does a Vivo Y31 cover fit the Vivo Y31 5G?
No. The 2021 Vivo Y31 is 163.9 × 75.3 mm and the Y31 5G is 166.1 × 77.0 mm, with a different camera island. A cover made for the 2021 phone is too small and the camera cutout won't line up. Buy a cover listed for the Y31 5G.
Is the Vivo Y31 5G cover the same as the Vivo Y31 Pro cover?
No. The two launched together and are close in size, but the Pro has a larger 6.72-inch screen and a 50 MP + 2 MP camera layout, so the cutouts differ. Order the cover listed for your exact model.
How do I know which Vivo Y31 model I have?
Open Settings, then About phone, and read the model name. Model number V2036 means the 2021 Vivo Y31. If you can't check settings, the phone colour helps: Rose Red or Diamond Green is the Y31 5G, Mocha Brown or Dreamy White is the Y31 Pro 5G.
Which is better for the Vivo Y31, a back cover or a flip cover?
For screen safety, a flip cover. The Y31 5G is a heavy 209 g phone with a big 6.68-inch display, and a back cover leaves that display open. A flip cover closes over the screen, and a wallet flip also carries your cards and folds into a stand for videos.
What is the price of a Vivo Y31 flip cover?
Our Vivo Y31 5G wallet flip covers are ₹599 in the four denim colours and ₹699 in Forest Green chambray, with free shipping across India.
