K2400 bright digit clock

I have built this and can get as far as a rotating green face but then got stuck.
Im using an Android phone and a laptop.

There are no specific instructions for Android

Can any one help or advise please.

If it stays green it means it tries to connect to the wifi network but doesn’t succeed.
Maybe you entered the wifi credentials incorrectly
Press the boot button for a few seconds and the light should turn Blue.
Then follow the same procedure as if you did the first time.
(Connect to hotspot, enter credentials, etc…)
