How to transfer photos and videos from damaged iPhone?

How do you transfer photos and videos from a damaged iPhone. My iPhone 8Plus is still on but the screen isn't responsive due to water damaged. I'd tried iTunes but not only that it didn;t back up my photos, it also has changed some of it to AMP format instead of JPG and the videos can't be played (its says device can't be reached) please help me. I have thousands of photos and videos there that worth a whole year memory:'( please help me:'( I've tried everything.

If you didn't back up your photos and videos to iCloud your only option is to take it to a repair centre specialising in liquid damage where they can repair the phone enough recover your data.

You'd likely have to get the screen fixed 1st.

Not sure if this has changed on Windows, but you could plug it in & access the camera roll through the main folder (Computer/My Computer) & get the media there.
