I have an Android phone accent a400 and I sent it to a repair store to change the broken screen.
After receiving the phone, I noticed that they did a reset to the phone and the internal memory doesn't appear in the file manager. Also the application SuperSU which was installed by default doesn't exist any more, so I installed ES file explorer and used it to verify that the system and racine folder still exist. Then I installed Framaroot after rooting the phone and the application SuperSU became visible.
Sometimes "the message was sent" popup alone when using the phone. How would I fix this?
