Haven’t worked on this one myself, but all the Samsung devices are pretty much the same formula. Remove the back, undo all the screws, remove the plates or midframe, disconnect everything starting with the battery, remove the main board and daughter board, remove and transplant any components that aren’t present in the new screen assembly (make sure to buy a replacement part with frame or you will have a much harder time), reinstall the boards, reinstall the battery, connect everything, put plates or midframe back on and tack down with a few screws to make sure the power buttons are making a good connection, test the device, if everything is good you can reinstall the remaining screws and then re-adhere the back.
