# I can't connect to my camera after updating the firmware

Troubleshoot connection problems after installing Firmware Update 4.0.0 on Q3/SL3 or 1.7.0 on D-LUX 8

## Migration of Bluetooth Pairings

After installing the latest firmware, **a new Bluetooth pairing is required** for the following cameras:

-   **D-Lux 8** — Firmware version **1.7.0 or later**
    
-   **Q3 family** — Firmware version **4.0.0**
    
-   **SL3 family** — Firmware version **4.0.0**
    

### **Why is a new pairing required?**

This change is required due to updated **EU regulations**. Devices sold in the EU must comply with the latest technical standards, which necessitates a renewed Bluetooth pairing.

## **What happens in Leica FOTOS?**

In most cases, **Leica FOTOS will automatically detect** that a new Bluetooth pairing is required. The app will guide you step by step through the process and help you recreate the pairing.

-   You will be asked to put the camera into **pairing mode** again.
    
-   The app will guide you through updating the pairing **without needing to remove the camera from Leica FOTOS first**.

## **I can’t establish a new pairing on my Android device**

On some Android devices, the Bluetooth pairing request may not appear as a pop-up dialog.

-   The pairing request may only be shown as a **notification** in the **Notification Center**.
    
-   If the phone is in **Do Not Disturb** mode, the pairing request may not be shown at all.
    

### **What to do:**

-   Check your **Notification Center** for Bluetooth pairing messages.
    
-   Make sure **Do Not Disturb** mode is disabled.
    
-   Retry the pairing process.
