The most common cell phone repair is a fix for a broken or cracked screen. In the majority of cases, this can be done in under an hour, while the customer waits in the store. There are some repair shops that will actually allow the customer watch the repair being done. The next most frequent cell phone problem relates to the phone's power supply and/or battery. This may or not be simply a matter of swapping in a new battery. Often the port itself has a problem. Switching it for a new one can do the trick. Other times there is a problem on your phone's logic board (think "mother board" for a computer). This latter situation can often be resolved, but only, perhpas, 50% of repair shops can/will do it. Just call and ask them. At any rate, most shops will fix phones on a contingent fee basis: i.e. you pay for results only if your phone is fixed successfully.
