Will my files in my phone be deleted after being repaired?

[AC Question]

My Samsung Galaxy S4 is going through the "black screen of death", so I'll have it repaired. But I'm wondering what will happen to my files? Will it be deleted?

Also, my phone has a passcode lock. Will this be gone after repairing my phone?

Welcome to AC.

As long as it is just the screen being replaced, no data nor any system changes should occur.
