Question about Samsung Cell Phones

1 Answer

Have samsung flight A797 that has a short in the USB jack. Will not charge and will not show unit as charging. What is causing the small black chip located on top of the circuit board below that USB jack to get very hot each time I put in the battery? The unit turns on but goes off after 30 seconds due to that chip overheating. How can I fix the chip from overheating?

The short is causing the over heating. there is most likely nothing you can do but get a new phone. get the usb jack replaced (cost about 30-50 bucks) from your phone provider
