@abdirahman25149, I found an iFixit-style guide over on the French site SOSav that shows you how to do the recommended screen plus frame replacement for this phone. That's the only fix for a cracked screen; it cannot be repaired.

Otherwise follow @jayeff's advice for finding a replacement screen and of course you can watch the video he provided as well.
