My iPhone randomly starts clicking by itself it’s mostly at the same position and it clickes itself repeatingly on the almost same position. I have to lock the phone and then it goes away. It happens randomly over the day without any special reason. Can it be fixed by cleaning the connectors or by changing the whole screen? (Phone fall into the toilett months ago[at least 7-8] but everything ist working perfectly, except this problem - which isn’t always)
It’s clearly been water damaged. As you’ve let it dry and continued to use it. The display is likely damaged, and you’ll have to replace that. While you’re at it, you’ll want to clean the board for water damage. You may get away with a general cleaning with 90% isopropyl alcohol, and a q tip. But I would recommend bringing it to a board repair shop, that has an ultrasonic bath, and can remove all the shields.

Chances are it is a bad screen. I would certainly take a look at the connectors though before spending money on a replacement screen. Follow this guide and be careful to disconnect the battery first and keep track of your screws.
