If you are an XR user, you can choose a phone case with two adapter holes to install dual cameras. This ensures that your camera is well protected and does not affect the camera function. In addition, it is recommended to choose a transparent phone case to optimize the quality and effect of the photo. There are hundreds of places selling such phone cases, such as Amazon, Taobao, and JD.com, so you can buy them easily. Finally, be sure to check the compatibility of your camera type and the holes with the phone case.
