HarmonyOS 7 Introduces Seamless Multi-Device Collaboration Even When Your Phone is Locked
- ✨ Huawei is rolling out the HarmonyOS 7.0 beta, introducing advanced multi-device collaboration capabilities.
- ✨ Users can now unlock their locked smartphones directly from secondary devices like tablets or PCs.
- ✨ The update supports convenient unlocking via lock screen passwords or biometric authentication methods.
- ✨ This upgrade unifies the device ecosystem, making cross-screen productivity faster and more secure.

Huawei is rolling out a new HarmonyOS 7.0 beta for its devices, which will enable users to access multi-device collaboration with other handsets even when the phone is locked. The company is giving a significant upgrade to its interconnection segment to further ease the user experience.
It’s the first time Huawei phone users will be able to unlock their handsets directly from the tablet or PC under the multi-device or multi-screen collaboration feature.
The new software version unlocks many useful features — from 3D spatial wallpapers to an upgraded outdoor mode.
But the highlight of HarmonyOS 7.0 beta is the new multi-device collaboration feature that enables you to link devices and work seamlessly even when your main phone is locked.
According to users, if the phone is locked and connected to the MatePad tablet, the multi-screen collaboration will support unlocking the main device (here, the locked phone) using the face or fingerprint method on the tablet.
Unlock Feature in Multi-Device Collaboration
Users can choose from the two options given below to unlock the main device right from the secondary one within a few seconds:
- Use phone lock screen password
- Face or fingerprint registration using a tablet

Multi-device or multi-screen collaboration in the Huawei device ecosystem lets your phone, tablet, and PC work as one unified system. It projects your phone display directly onto other devices, such as a tablet or MateBook laptop.
However, it doesn’t fully work if the main phone is locked and attempts to access or mirror a locked phone from another screen, prompting you to unlock the main device first for security reasons.
HarmonyOS 7.0 closed beta is now out for a handful of flagship Huawei smartphones and tablets. You can check the details on how to participate in the testing pool below.
