We only use the best parts but let's be honest: Sometimes technology simply lets you down. Whether you brought your device in for a broken screen, battery replacement, charging port trouble, new headphone socket, speakers, faulty cameras, antennas, or anything else, we fully guarantee our work. If your part fails for any reason (not including water damage or obvious physical damage) we will replace the part at no cost to you. That said, it is extremely rare to have one of our parts fail or malfunction, so rest assured your phone is in good hands.
