Taking out my sim card tray today to take out the micro sd card before i sell the phone, and the sim card tray snapped halfway across. I wasnt even pulling hard its the most fragile thing in the world. Luckily i stopped pulling halfway and carefully and extremely slowly took it out, took about couple minutes because the broken part was snagged inside the phone. I was !#^&@@ off so I pull with strenght and I damage the sim slot, how to replace it?
I concur, those SIM card trays on Samsung’s S7/S7 Edge are very fragile! I broke one in the same fashion you did when repairing a teacher’s S7 Edge. You can buy a replacement SIM card tray at the link below. Galaxy S7 SIM and SD Card Tray
