Questions and Answers

Trying to connect AllShare cast to Galaxy S3 phone, it tells me to turn ON screen mirroring and I can't get this to open to connect dongle?

How can I turn ON screen mirroring on Samsung Galaxy S3


If you followed the instructions and still can't get it to connect to the dongle you may need a device that recognizes that particular dongle. You should check into getting the AllShare Cast Wireless hub. This will allow significantly better connections with a wider array of devices.

How to use Screen Mirroring in Galaxy S3?


When I want to share my Galaxy S3 with the other Galaxy S3 screen mirroring is not working. Every time it displays ' Device not found ' on both the phones.

Both the phones have this option enabled.

Why is it so ? What are the steps to do screen mirroring ?




Make sure that your connection is strong. If it's not, that is more likely the reason why your devices don't detect each other.

Also, it may help if you will restart both devices first. Sometimes, this happens when the system is stuck reading some information.
