It is crucial to fully turn off the device before replacing the front camera for iPhone 14 to ensure safety and prevent potential damage to internal components. When ready to remove the screen, use a hair dryer to evenly heat its edges. The heat softens the adhesive, making disassembly easier and reducing the risk of screen breakage. This method ensures a smoother repair. Next, handle the flexible battery plug carefully. Check and eliminate any abnormal issues to maintain stable connections and avoid electrical problems.
