Go to AliExpress.com They should have sealing tape and new or slightly defective screens. I recently replaced my S21+ screen with a slight defect for ~$40. It has a small black spot at the bottom left of the screen that is seldom seen. You can also get backs. Use a suction cup to pull up the screen and back. I didn't on the back and broke it. For a suction cup, I used one that came with a device to mount it on my car window. I used a hair dryer to soften the glue tape. That replacement tape is very thin and sticky. Try not to touch it with your fingers. It will end up folding and sticking to everything.
