Please ensure that you have purchased the correct cover for your Agora phone, as there are different variants of the Agora phone, each requiring a different cover - you can check the product listing to confirm this.
If you have purchased the correct cover, please be aware that the flip cover replaces the existing back cover of the phone.
In order to use it, you will need to remove the back cover of the phone and attach the flip cover in its place.
If you require further assistance, feel free to contact our Support team by submitting a question below.
