The camera in the Grom Social app requires 3d capabilities which only newer iPhone’s and Android devices have. This leaves users with older devices not able to access or use the camera inside the Grom Social app.
We do have a solution in the works and should be available in August 2019. This will allow all devices to access and use the Grom Camera and editing features. Since 3d is limited to device support, only newer devices will be able to access the funny faces and 3d effects.
