A:AnswerThis particular one is made especially for the Galaxy S21 FE, which has a 6.4 inch screen. I believe the Galaxy S21 has a 6.1 inch screen, so this would be too big for that. However, check the specs and the screen dimensions to make sure.
A:AnswerYes, if there is a mall near you that has a phone repair kiosk like zagg, they have protectors, batteries, new screens. However I have never broke a screen so I dont know the cost. I use otterbox phone protectors.
