That’s an interesting request! The fact that you are looking for a single combo pack for both the Oppo A3 Pro 5G and the Oppo K12x 5G suggests you might have noticed their similar dimensions and design.
My search confirms that accessory makers often list their products, especially clear/transparent back covers, as compatible with both the Oppo A3 Pro 5G and the Oppo K12x 5G because the physical phone dimensions are nearly identical.
✨ Shared 3-in-1 Combo Features (Transparent)
A transparent 3-in-1 combo pack for these models will likely offer the following items, with a key caveat on the Camera Lens Protector:
1. Transparent Back Cover (The Shared Component)
This item is generally compatible with both phones.
| Feature | Description |
| Material | Soft, flexible TPU (Thermoplastic Polyurethane) or a Hybrid design (TPU bumper + Hard PC clear back). |
| Design | Crystal Clear to show off the original color and design of the Oppo A3 Pro or Oppo K12x. |
| Protection | Features Air-Cushion Technology (small bumps) on the corners to absorb shock from drops, and a raised lip around the screen. |
| Compatibility | Excellent: The overall height, width, and thickness are almost identical, allowing one case to fit both phones perfectly. |
2. Tempered Glass Screen Protector
This item is also generally compatible.
| Feature | Description |
| Fit | Designed for the 6.67-inch display that both models share. |
| Protection | Typically 9H hardness glass with an Oleophobic coating for scratch resistance and anti-fingerprint properties. |
| Compatibility | Excellent: Both phones have the same screen size and dimensions. |
3. Camera Lens Protector (The Key Difference)
⚠️ IMPORTANT NOTE: You must check the specific camera cutouts for this piece.
While the body of the phones is similar, the camera modules are different, which means the lens protector might only fit one model perfectly.
| Phone Model | Main Camera Resolution | Camera Module Design Impact |
| Oppo A3 Pro 5G | 50MP + 2MP Dual Camera | The layout of the two lenses and flash might require a specific cutout. |
| Oppo K12x 5G | 32MP + 2MP Dual Camera | The layout of the two lenses and flash might require a different specific cutout. |
Action Recommended:
-
If the combo mentions it is universally compatible, it likely uses a large, single cutout that covers the entire camera housing, which may be a less precise fit.
-
If the combo includes a Camera Lens Protector, ensure the product page confirms the exact fit for the specific camera ring arrangement of your model (A3 Pro OR K12x).
