To remove and replace the back cover and display panel on your Samsung Galaxy S10e, you will need to follow a series of steps. First, heat the phone's back cover or display to soften the adhesive using an iOpener, hair dryer, heat gun, or hot plate. Be careful not to overheat the phone. Once heated, use opening picks or suction cups to create a gap and slide them along the edges to slice through the adhesive. After removing the back cover, proceed to remove the screws and various components to access the display panel. When reassembling the phone, make sure to follow the instructions in reverse order and test the repair before sealing the back cover in place.
