Google home matter connectivity getting failed for some devices.

[kartikGupta1502]

While attempting to onboard a Matter device (Sonoff) using the Home SDK in my Android app, we encountered connectivity issues on two devices: the Pixel 7a and Moto G 54. I've verified that Bluetooth was functioning properly, the mobile devices were connected to a 2.4 GHz network, and the network signal strength was strong.

Model details:

pixel 7a	Android 14
Moto G 54	Android 14

I was able to successfully onboard the device on other Pixel 7a models, but with this particular unit, the process failed. I also tried updating Google Play Services and resetting the Wi-Fi and Bluetooth modules, but the issue persists.

Errors:
1. Can't reach google - check your internet connection and try again.
2.Can't connect your device - check your device instructions.

Hello @kartikGupta1502 ,

Thank you for reaching out to us with your issue. Based on what you have described above, can you try resetting your Matter Device (Sonoff) and then try commissioning the device again ?

Yes we tried it multiple times the same Sonoff device is getting connected with multiple different mobile phone across different OEM's but not with the pixel

I encountered an interesting situation with Matter device onboarding:

Scenario 1 (my Pixel 7a):

• Required a hub to successfully onboard the Matter device via Google Home
• Direct connection failed

Scenario 2 (Other devices including another Pixel 7a):

• Successfully onboarded directly without requiring a hub
• Direct connection worked fine

What could explain this inconsistency in behaviour where identical phone models (Pixel 7a) have different hub requirements for Matter onboarding? Why does one Pixel 7a require a hub while another doesn't?

FYI: After resting devices are working fine
