de727, we want to help you figure out what is going on with your Galaxy S7. We recommend taking the device to a store location to have it inspected. We can also do troubleshooting to try to have it fixed. When did this first start? We want to give you an option that might help get your device past the loading screen. Have you tried using the Software Repair Assistant? Here is a link to help you with this step, https://www.verizonwireless.com/support/knowledge-base-80201/. Let us know if this works or if you still need assistance with your device.
