When repairing an iPhone , you can initially try to fix it on your own with a self-purchased repair kit and the online guide. But if you really aren’t into the technical details and cant wrap your head around the circuitry and don’t want to cause further damage, hand it over to an expert. Ensure that it is an expert, who specializes in iPhone model repairs; you can find a reputed store or call the technician home. It will be well worth the money, as you get a professional to solve the issue.
There may be multiple problems requiring attention such as a cracked screen, bleeding colors on the LCD screen, or battery dying out too soon. It is best not to attempt these repairs on your own. Going to an Apple store may mean you need to replace the entire phone or buy a new one, instead find a specialized technician who will repair the iPhone and have it back to you good as new. Enquire and research about repair stores beforehand. Talking to friends and family or enquiring with colleagues who have the same phone is a good idea. Find out reviews and recommendation, and make an informed decision. Consider doing some research on shortlisted options. Calling a technician home is an option, if you don’t wish to leave your phone at a store, and it saves you a lot of trouble too.

Whether it is damage from water exposure, USB issues finding a good store that specializes in repairing iPhones is important.
