My phone updated and has not worked properly since.I used it Friday morning at 7:30 am it updated at 8:00 am,and the home screen blinks from black to blank,it never loads totally,then blinks to black again.The only way i can use the phone,is if i push the square menu button while the screen is black,i can get into the menu screen and use things from there.So the phone actually works,just the home scren wont.I unistalled all apps that i had running on the home screen,changed backgrounds...etc.Still the same,can anyone help? TIA
