Redmi Note 4 Dual Camera: The Real Answer
The Xiaomi Redmi Note 4 does not have a dual camera setup. The standard Redmi Note 4, released in early 2017, features a single 13-megapixel rear camera. The Redmi Note 4X, a variant sold in some markets, also has a single 13-megapixel camera. No official version of this phone shipped with two rear lenses.
Why the Confusion Exists
The dual-camera trend was just beginning when the Redmi Note 4 launched. In 2016 and 2017, several flagship phones like the iPhone 7 Plus and LG G5 had dual lenses, but budget and mid-range phones mostly stuck with single sensors. Xiaomi did release dual-camera phones in the same era, but they were different models, such as the Mi 5s Plus and the Redmi Pro. The Redmi Pro, in particular, had two rear cameras and looked similar to the Redmi Note 4 from the front, which may cause people to mix them up.
Another source of confusion is the Redmi Note 5, the direct successor to the Note 4. The Redmi Note 5 Pro, launched in early 2018, had a dual rear camera (12 MP + 5 MP depth sensor). If you see a Redmi Note device with two rear lenses, it is almost certainly a Note 5 or newer model, not a Note 4.
Camera Hardware on the Redmi Note 4
The Redmi Note 4 uses a single 13-megapixel rear camera with an f/2.0 aperture and phase-detection autofocus (PDAF). The sensor was typically a Samsung S5K3L8 or OmniVision OV13880, depending on the production batch. There is no secondary lens for depth sensing, wide-angle capture, or monochrome photography.
The front camera is a 5-megapixel sensor with an f/2.0 aperture, also a single lens. Neither camera can produce the bokeh (background blur) effect that dual-camera phones achieve through hardware depth mapping. The phone does have a software “Beautify” mode, but that is a skin-smoothing filter, not a dual-camera feature.
What Dual Cameras Do and Why It Matters
Dual cameras on smartphones generally serve one of three purposes:
- Depth sensing: A second lens captures depth information to create a blurred background in portrait shots.
- Wide-angle capture: One lens is standard, the other is ultra-wide, letting you switch field of view.
- Improved low-light performance: A monochrome sensor captures more light and combines with the color sensor for better detail.
Since the Redmi Note 4 lacks a second lens, it cannot do any of these. Portrait mode with background blur is absent. If you want that feature, you need a phone with dual cameras or a newer single-camera phone that uses AI-based depth estimation (which the Note 4 also lacks).
How to Verify Your Phone’s Camera Count
If you are unsure whether a specific device is a Redmi Note 4 or a different model, check the physical hardware:
- Turn the phone over and look at the rear camera module. The Redmi Note 4 has one circular lens in the top-left corner, with a single LED flash beside it.
- If you see two lenses side by side, it is not a Redmi Note 4. It could be a Redmi Note 5, Redmi Note 6 Pro, or another model.
- Check the model number in Settings > About Phone. The Redmi Note 4 is model 400 (China) or 410 (global). The Redmi Note 4X is model 401 or 402.
- Look up the model number on Xiaomi’s official support site to confirm specifications.
This quick check will settle any confusion before you buy a used phone or install a custom ROM.
Common Misconceptions and Myths
Some online forums and video reviews claim that the Redmi Note 4 has a “dual camera” because the flash is placed near the lens and looks like a second sensor. The flash is a single LED, not a camera. Another myth is that a software update could enable dual-camera features. This is impossible because the hardware lacks the second sensor; no software can create depth data from one lens.
There is also a variant called the Redmi Note 4 Global (sometimes labeled as Redmi Note 4X in India). It has the same single-camera hardware. No regional version has two rear lenses.
Alternatives With Dual Cameras
If you specifically want a dual-camera phone in the same price range as the Redmi Note 4, consider these options from the same era or slightly newer:
- Redmi Pro (2016): Dual 13 MP + 5 MP rear cameras, but it has a different processor (MediaTek Helio X20/X25) and a slightly different body.
- Redmi Note 5 Pro (2018): Dual 12 MP + 5 MP rear cameras with portrait mode. This is the natural upgrade from the Note 4.
- Mi A2 (2018): Dual 12 MP + 20 MP rear cameras, though the second lens is used for low-light, not depth.
- Honor 7X (2017): Dual 16 MP + 2 MP rear cameras, a direct competitor to the Redmi Note 4.
These phones offer the bokeh effect that the Note 4 cannot. However, they are all older models; if you are buying new today, any modern budget phone from Xiaomi, Samsung, or Motorola will have a dual or triple camera system.
Frequently Asked Questions
Does the Redmi Note 4 support portrait mode?
No. Portrait mode with background blur requires either a dual-lens camera or advanced AI depth estimation, and the Redmi Note 4 has neither. Some third-party camera apps can simulate a blur effect, but the result is not true depth-based bokeh.
Can I install a Google Camera app to get dual-camera features?
No. The Google Camera app (GCam) can improve image processing on some phones, but it cannot add hardware that is not present. It will not give you depth effects or wide-angle capture on a single-lens phone.
Is the Redmi Note 4X different from the Redmi Note 4?
The Redmi Note 4X is essentially the same phone with a different processor (Snapdragon 625 vs. the MediaTek Helio X20 in some Note 4 versions). The camera hardware is identical: a single 13 MP rear sensor. The X is not a dual-camera variant.
Why do some photos from the Redmi Note 4 have a blurred background?
That is likely due to close-up focusing, not a dual-camera effect. When you focus on a subject very close to the lens, the background naturally blurs due to the shallow depth of field. This is an optical property of any camera, not a special feature.
What is the best way to get portrait shots on a Redmi Note 4?
You can use a third-party app like Snapseed or PicsArt to manually blur the background in post-processing. The result is not automatic, but it can mimic the look of a dual-camera portrait mode.
