It won't update. Bombards me with notifications constantly. Have not been able to open notification for at least 2 years! When I asked for help was told it was all my fault that I invited all those things in that won't leave me alone. I INSTALLED SAMSUNG MYSELF. WHETHER YALL REMEMBER OR NOT. IN 2012 ON MY ORIGINAL PHONE B4 I DROPPED IT, BROKE IT N HAD TO GET TH FACTORY RETREAD, USED 1, IT HAD SAMSUNG ALREADY ON IT. BUT NOT MY ORIGINAL. I WISH ID NEVER DONE IT. SAMSUNGS BEEN PAIN IN MY NECK
