All legitimate iphone repair services will be certified by Apple, therefore before trusting the shop with your phone and money, always ask for credentials and certificates. Asking for credentials is extremely important because it proves that the shop has a track record of being efficient, trustworthy and most importantly accurate in their repairs. Certification is proof that they have the qualifications to do the job, that they claim they can do. If they have no certificates or credentials that they want to show you, then consider moving on to a different shop. When talking to a technician it is always best to ask if they offer warranty on repair. Warranty will ensure that you will get free repair if your phone fails again.
