Fairphone 3 not reacting anymore

My phone fell down the other day. I can start it but it takes ages. Then when it is at the lock screen, it just flashes and does not react. Does anyone now what might be broken?
Thank you!

I would dismount and remount the display, that often helps with problems after a drop.

Make sure to heed the (black font) advice in the final Step 9. And while you’re at it, you might want to use the opportunity to clean the insides of the device with some high % cleaning alcohol (give it some time to evaporate then) – although this is not a must.
