@phanhug.93 Thanks for your detailed post.

Your issue has been forwarded to a team and we will get back with further updates once more information becomes available.

@vjgee I found the reason:
I coded follow guideline example ( https://github.com/Web3Auth/web3auth-pnp-examples/blob/main/android/android-example/app/src/main/java/com/sbz/web3authdemoapp/MainActivity.kt )
The reason is here:

 whiteLabel = WhiteLabelData(
                    "Web3Auth Android Example", null, null, "en", true,
                    hashMapOf(
                        "primary" to "#229954"
                    )
                ),

if I config whiteLabel , japan device can not login look like above topic images. On the contrary, i don’t config whiteLabel, everything works well.
I think web3 team should re-check it.
I have received backlash from customers about the problem. I hope the dev-team will be more careful about the source code in the sample project.
Now, i just removed whiteLabel configuration from project to fix this problem.
Thanks for all

I have tried using same i.e. changing device language to japanese. It’s working. Please see below.
