Blurred video on Xiaomi phone: how to fix and return clarity

Videos on your Xiaomi are fuzzy, with artifacts or soap effect? The problem is found on both the budget Redmi and the flagship Mi 13 Ultra — and it's not always the camera's fault. Most blurring is due to incorrect settings, software failures or hardware limitations. In 80% of cases, the problem can be solved without going to the service center — just know where to look.

We analyzed user feedback from the 4PDA forums, Mi Community and Xiaomi technical documentation to collect 7 proven ways to restore clarity to video. In this article, we provide step-by-step instructions for different scenarios, from basic settings to hidden parameters of the engineering menu. And if your case is unique, at the end you will find an FAQ with answers to rare questions (for example, why blur appears only at zoom or in the dark).

1. Check the basic camera settings

Before digging deeper, make sure the problem isn’t in standard shooting options. Xiaomi often resets the camera settings after updates or reboots, and users shoot low-resolution videos for years without even knowing it.

Open the Camera app and go to the Video section. Notice three key parameters:

• 🎥 Video resolution: should not be lower than Full HD (1080p). On flagships (Mi 12 Pro, Redmi) K60) readily available 4K — But remember that it eats away at memory and can slow down on weak chips.
• 🔄 Stabilization: Turn it off if you're shooting from a tripod or in static scenes. Xiaomi's algorithms sometimes "restabilize" by adding blur at the edges of the frame.
• 🌙 Night mode: forced on Night Mode during the day leads to a "soap" effect. Automode works better.

If you're shooting in manual mode (Pro Mode), check the shutter speed. Too long exposure (e.g., 1/15c) will lead to lubrication even with minimal hand movements. The optimal value for video is 1/30c–1/60c.

💡

On Xiaomi with a Snapdragon 8 Gen 2 processor (like the Mi 13), enable the HDR10+ option in the video settings – this will improve detail in dark and light areas without losing clarity.

2. Clear the cache and data of the Camera application

Camera failures are often due to corrupted cache or temporary file conflicts, especially after MIUI updates, when new video processing algorithms encounter old data.

To clear the cache:

1. Go to Settings → Applications → Application Management.
2. Find the Camera (or Camera on global firmware).
3. Press Warehouse. → Clear the cache.
4. For a complete reset, click Clear Data (⚠️ Warning: This will remove all custom camera settings!).

Once cleaned, restart your phone. If the blur is gone, the problem was software. If not, move on to the next step.

3. Update firmware and camera drivers

Xiaomi regularly releases patches to fix camera bugs, especially on newer models (Redmi Note 12, POCO F5).Outdated firmware can be a cause of blurring due to:

• 🐛 Unoptimized video processing algorithms.
• 🔧 Conflicts with camera modules (for example, after changing the display).
• 📱 Mistakes in work ISP (Image Signal Processor – the processor responsible for image processing.

Check the relevance of the firmware:

1. Go to Settings → About the phone → System update.
2. If you have an update, install it. Use Wi-Fi for stability.
3. After the update, perform a soft reset: pinch Power + Volume up for 10 seconds.

If there are no updates, but the problem remains, check the version of the camera drivers through the engineering menu (instructions in the next section).

4.Configure hidden settings through the engineering menu

Xiaomi has hidden camera settings that allow you to manually adjust the sharpness, noise reduction and bitrate of the video, which are often confused after resetting or firmware.

To get into the engineering menu:

1. Open the Camera app.
2. Twice tap the screen in the area to the right of the down button (the "Engineer Mode enabled" toast should appear).
3. Return to the main camera menu, and now a new Engineer Mode section will appear.

In the engineering menu, pay attention to:

💡

The changes to the engineering menu only apply to the current session of the shooting. After restarting the camera, the settings are reset!

5. Check for hardware problems

If software methods do not help, the cause of the blur may lie in physical defects:

• 🔍 Dirt on the lens: even microscopic dust particles or greasy prints scatter light, creating a "veil." Wipe the lenses with a microfiber wipe (do not use alcohol!).
• 💥 Camera module damage: Falls or bumps may cause the focus to shift or the lens to crack, and check if the camera is breathing when pressing the body.
• 🔋 CPU overheating: At high temperatures, Xiaomi artificially reduces camera performance.Use the app CPU Monitor for diagnostics.

A critical sign of hardware malfunction: blurring only occurs when zoom or under certain lighting conditions (e.g., when shooting against the sun), in which case only a replacement camera module will help.

✅ Check the lenses for scratches and dirt

✅ Test the camera in different lighting conditions

✅ Start a stress test of the processor (application) AIDA64)

✅ Check the camera module mount (gently press the body around the lens)-->

6. Use third-party applications to shoot

Xiaomi’s stock camera app doesn’t always make the best use of hardware. Alternative software (such as Open Camera or Filmic Pro) allows you to:

• 🎬 Customize bitrate video manually (up to 100 Mbps on flagships).
• 🔍 Disable software stabilization that adds blur.
• 📊 Choose a codec (H.265 It gives you better quality with the same file size).

Set up the Open Camera for maximum clarity:

1. Set 4K resolution (if supported).
2. Enable Force video 4K in the settings.
3. Turn off Video stabilization.
4. Set the bitrate to a maximum (e.g. 50 Mbps for 1080p).

Compare it to a stock camera. If the video is sharper, the problem is MIUI algorithms.

7. Reset the phone to factory settings

If all the previous methods didn't work, the last thing left is a complete reset, which would delete all the data, but bring the camera back to the factory state, eliminating software conflicts.

How to reset Xiaomi without losing important data

1. Create a backup through Settings → Additional → Backup and Reset.
2. Go to Settings → About the phone → Reset settings.
3. Choose to erase all data.
4. After a reboot, don’t restore data from the backup right away – check the camera first.

⚠️ Note: On models with MediaTek (Redmi) 10A, POCO M4 Pro) the reset may cause the bootloader to lock.Be sure you have it unlocked before the procedure OEM Unlock in Settings → For developers.
