Yesterday afternoon somewhere between 5 and 6 pm, I noticed that an update was available from Samsung. I tapped the notification, and the rest as they say was history. Countless battery pulls, attempts at clearing cache, and so forth, with no signs of its former life. I went to my local Sprint store this morning, and low and behold their message boards were being flooded by people like me, and fellow Sprint store techs. Samsung bricked my phone. It is not recoverable, and now backlogged for replacement. UGH! The Note 4 is the best phone I have ever used. Next best was my Palm Pre. HAs anyone else had this happen to them?
