Hey there and welcome to the Samsung UK and EU Community Forum

Sorry to hear of your issues.

Where did you take your device to have the film replaced please

Hello @Aiven1404 and may I extend a Warm Welcome to the Samsung Community Forum Section for Uk and Eu Members 👋 

If you've purchased a replacement screen protector yourself from a ³rd party Manufacturer's website then it may not be properly compatible, or isn't fitted quite correctly. 

If a Highstreet Store that deals in phone repairs etc has replaced the protector, then you'll need to go back to them. 

Hopefully the actual display hasn't been affected via the removal of the factory fitted screen protector. 

If a Samsung Service Centre has replaced the screen protector then get back in touch with them as their work is guaranteed. 

You can run the diagnostic tool in your Samsung Members App to see if that highlights anything. 

Ultimately my advice is to go through a Samsung Service Centre. 

If i can be of any further help please don't hesitate to ask  😎
