Oh no. Can the place you bought it from send you a replacement? I don’t know if you will have success with doing that, but it might be worth a try.
If they won’t, then maybe open the back and see if the connector can be re-seated. I hope it doesn’t come to that, but if you decide to do that, could you take some pictures of the internals and post them, for the rest of us? X80 Pro needs some hardware mods done on it to improve wifi and maybe even put in a bigger battery and separate charging port. That could help someone decide to do that.
Anyway, sorry to hear that, I hope you can get a replacement unit.
