Repair of Android Devices

I think you have to be more specific with your question, its going to depend really on what part of the phone is broken.

If it is hardware damage take it to a technician, probably depending on the company you are going to have to buy a new one.

Your question is kind of ambiguous so I’ll try to answer the most common scenarios.
If you bricked it there’s nothing much you can do.
If you broke the screen, you can order one online and replace it yourself, or you can have somebody at a shop replace it.
If you damaged it’s innards so to speak, your phone is not worth much anymore, your best bet is to try and sell it on ebay.

Depends on what kind of problem you’re facing. An Android device is no different than other device when you say you need it “repaired”; some things you can do it yourself, and some other things have to be done by a specialist.

There are a good number of techs popping up these days. Where I live in Tempe there is one right next to ASU and I heard he has pretty decent prices. Just google “android repair [your zipcode]” and you might find someone.

No bring it to the local store and you will be fine.

Whatever the problem is, it’s better to have someone with experience repair it for you if it’s complicated. I myself check a number of resources, mostly XDA forums. They’re pretty helpful.
