Should you change the glass?

My son's smartphone crashed, or rather, the glass of the smartphone cracked from hitting the concrete. The phone works as before, but the entire screen is on the web. We decided to repair it, but on the Internet, many write that when replacing the glass, the smartphone will no longer work as before. The glass itself is on the "aliexpress" 3100, the master will take it for work. Tell me who knows if it's worth repairing?
