At this point,
your iPhone has generated a WiFi connection too.
On the Android phone, open the WiFi and connect to the WiFi hotspot created by the iPhone. For example, it would be something like iOS fb466 or iOSfb466 – It can differ according to your phone.
Connect to this WiFi on your Android now. The password would be the name of your WiFi connection. For example, if the hotspot name is iOS fb466, the password would be iOS fb466. If it is iOS fb466, the password would be iOS fb466. Be careful about the spaces.
Open Move to iOS app now and enter the code again. It will work. That’s all.
Android手機連翻iPhone gen出嚟嘅WiFi AP就connect到,琴日就係咁解決咗。
