i suggest to apply heat on the corners of the front screen to lose the adhesive a lil bit and push from the bottom back of the phone right where the wireless charger is because of the charging port

the way we do it at Get it fixed cellphone repair calgary is with a heat gun, wich is way easier than this, make sure to wear some gloves and dont worry to use to much heat as long as you point just to the back of the phone, (the back panel is thick enough to protect the logic board from over heat) instead of the usual blue plastic piece i sugest to use the thinnest metal razor knife and a business card so you can insert the business card and move it all around the frame, those blue plastic things are way too thick that will break the glass panel if you apply to much pressure
