Hello, Welcome to the Community. We understand how upsetting it is that you are unable to use the phone due to it no longer connecting to any networks or devices. 

Some steps to try to correct the connection concerns would be to clear the cache partition and repair apps in the recovery menu.

To get to recovery mode:
- Turn off phone
- Once off, hold down volume up and power buttons simultaneously
- When Samsung logo appears, release power button BUT KEEP HOLDING VOLUME UP until the recovery menu appears
- Use volume buttons to navigate down to clear cache (NOT CLEAR DATA/ FACTORY RESET)
- Use power button to select.
- Run the repair apps option and your device will restart. 

If the phone will still not connect, try testing in Safe Mode. https://www.samsung.com/us/support/answer/ANS00062983/
