FP3 Display freezes! Display noise issue

Hello, my screen is frozen like on the pictures above since this afternoon. It happened after a bag with my phone in it fell, although it was really not from high up and didn’t seem like much, but I guess it must have moved something in the phone.
I tried opening it up and twisting it a bit, but no luck so far.
I would welcome any other ideas, if anyone has some.
I would really hate to have to buy another phone after less than a year with this one… :frowning:
