How to install your picture on the watch Xiaomi Mi Band 4: 3 proven ways

The Xiaomi Mi Band 4 fitness bracelet has become a hit with smart electronics fans thanks to its combination of affordable price, long autonomy and wide customization options. One of the most popular features is the ability to set your own picture on the dial, turning the device into a unique accessory. However, many users face difficulties: where to find the right images, how to crop and download them correctly, why does the dial not change after synchronization?

In this article, we will look at all the working ways to install images on the Mi Band 4, from the official method through the Mi Fit app to alternative solutions using third-party utilities. You will learn what formats are supported, how to avoid common errors (for example, loss of image quality when converting to.bin format), and get ready-made templates to create perfect dials.

Image requirements for Xiaomi Mi Band 4

Before you upload a picture to the bracelet, it must be properly prepared. Mi Band 4 has a AMOLED- screen with a resolution of 120×240 pixels, but not all images will fit out of the box.

• 📏 Resolution: 120×240 px (vertical orientation) If you download a picture of a different size, it will be cropped or stretched.
• 🎨 Format:.png or.jpg (no transparency). To convert to.bin (official dial format) you will need additional software.
• 🖼️ Color gamut: AMOLED- The screen supports deep black (the pixels just turn off), so it’s best to avoid dark backgrounds — they eat up battery power.
• 📁 File weight: no more than 100 KB. Heavy images may not load or cause synchronization errors.

Important: the bracelet only displays static images. Animated dials (like on the Mi Band 5/6) are not available here. Also note that widgets (steps, pulse, time) occupy part of the screen, so the center area of the picture should not be loaded with important details.

⚠️ Warning: If you use custom firmware (e.g., Amazfit), the image requirements may differ, in which case check the documentation for your version of the software.

Method 1: Installation via the official Mi Fit app

The most reliable, but also the most limited, method is to use Xiaomi’s proprietary Mi Fit app, which is suitable for users who don’t want to mess with file conversions and third-party programs.

1. Download Mi Fit from Google Play or App Store and log in through your Xiaomi account.
2. Connect the bracelet to your phone via Bluetooth and wait for the data to synchronize.
3. Go to Profile → Mi Band 4 → Dials.
4. Select My dials category and click Add.
5. Upload the prepared image (in.bin format) or select from the suggested templates.

The problem is that Mi Fit doesn’t support direct downloading of.png/.jpg. To get around this limitation, you need to pre-convert the picture to.bin format using the Mi Band 4 Tools utility (available for Windows and macOS).

⚠️ Warning: After converting to.bin, the image may lose brightness. To avoid this, increase the contrast of the source by 10-15% in any graphics editor (e.g., Photoshop or GIMP).

Method 2: Use Notify & Fitness (without conversion)

If you are afraid of the process of converting to.bin, an alternative option is the Notify & Fitness for Mi Band app. It allows you to download images directly in.png and.jpg formats, and also offers advanced display settings (for example, selecting the position of watches and widgets).

Instructions:

1. Install Notify & Fitness from Google Play (no iOS equivalent).
2. Connect the bracelet via the app (you may need to disable Mi Fit in Bluetooth settings).
3. Go to the Display section → Dials → My dials →
4. Click + and select an image from the gallery. The app will automatically crop it to screen resolution.
5. Set up the location of the watch and widgets (optional) and save.

Advantages of the method:

• ✅ There is no need to convert files to.bin.
• ✅ Transparency support (if sourced in.png).
• ✅ Possibility of fine-tuning the position of elements (time, date, steps).

Cons:

• ❌ iOS doesn't work (Android only).
• ❌ Sometimes synchronization errors occur with the bracelet (reconnecting helps).

Method 3: Manually create a dial through Gadgetbridge

For advanced users who want complete control over the look and feel of the bracelet, Gadgetbridge is an open source application that supports not only the Mi Band 4, but also other Xiaomi/Amazfit devices.

• 🎨 Create dials from scratch by tuning each pixel.
• 🔄 Change fonts, colors and widget locations.
• 📥 Download pre-made templates from the community.

How to set the dial through Gadgetbridge:

1. Download the application from the official website (available for Android and Linux).
2. Connect the bracelet: go to Settings → Devices → Add the device.
3. Select Mi Band 4 and wait for the sync.
4. Go to the Manage of dials → Create a new one.
5. Upload the background image (.png) and adjust the layers (time, icons, etc.).
6. Save the project and send it to the bracelet.

Gadgetbridge takes more time to set up, but gives you maximum freedom. For example, you can create a dial with animated elements (although the Mi Band 4 itself does not support them, but some custom firmware does).

Where to download the ready dials for Mi Band 4

You want to be a little bit more involved in creating your own images? There are a lot of resources on the Internet with ready-made dials.

When downloading dials, pay attention to:

• 🔍 The firmware version of the bracelet (some dials only work on the latest updates).
• 📌 Resolution - This must be the same as 120×240 px.
• 🔋 Optimization for AMOLED (black background = battery savings).

⚠️ Warning: Only download dials from trusted sources..bin files may contain malicious code if created using modified tools.

Frequent mistakes and their solutions

When installing dials, users often face typical problems, and let's look at the most common ones and how to fix them:

1.The dial does not change after synchronization

Causes and solutions:

• 🔄 Reboot the bracelet: disconnect it from the phone, turn it off (hold the 5 seconds button) and turn it on again.
• 📱 Update the app: Older versions of Mi Fit or Notify & Fitness may have bugs.
• 🔌 Reset the connection: Remove the bracelet from the Bluetooth device list and reconnect.

2. the image is not displayed in full or distorted

This is due to incorrect resolution or formats.

• 📏 File size: Must be exactly 120×240 px.
• 🎨 The format is only.png or.bin (for Mi Fit).
• 🔍 Transparency – if it is in.png but is not supported by a dial, the background will turn white.

3.After changing the dial, the battery quickly goes down

The AMOLED- Mi Band 4 screen consumes more power when displaying light colors.

• 🖤 Use dark themes with a black-dominated themes.
• ⏱️ Reduce the backlight time in the bracelet settings.
• 🔋 Turn off automatic pulse detection (if not necessary).

💡

If the dial is not installed via Mi Fit, try temporarily disabling VPN or antivirus – they can block synchronization with Xiaomi servers.
