How can I fix my phone it not doing anything I can't see anything what can I so to fix it

Check with I buy on main st downtown Boonville

Any at&t can check it out for free if you have them. Factory reset? Don't go to the boonville store. The real at&t in Columbia is better (Not authorized retailer).

Buy a new phone anymore they are $20

Take it to where you bought it from to see if they can help you
