I have a Walmart Straight Talk phone made by Alacatel. The computer stopped seeing it when I plugged it in. I went and did all the usual stuff like checked the developer debugging, changed usb cables , tried it in different computers , it appears the phone is no longer putting out . Computers are not able to see this phone. They charge fine with these USB cords. I called Straight Talk , They deny it's their problem told me to call Walmart, I called Alcatel , they do not accept the problem either said it was straight talk's problem. All I want to do is to be able to get inside my phone. It seems to work fine otherwise Android 4.4.4 Kitkat OS . If I did already the suggestions that everyone gave in previous posts and it's still not working, is my phone broken?
