My screen is shattered how much would it cost to get it fixed

If you wanted to repair the phone your self, the display assembly is around $30-35 USD. It would likely be $20-$40 labor for a shop to do it. https://www.ebay.com/sch/i.html?_from=R4

Buy oem screen on eBay 28 bux, prolly 20 labor from “pro…” Or YouTube that ish yourself.

They are many places where you can get a display dependent on your location. See the guide below. ZTE ZMax Pro Display Assembly Replacement
