My S5 was a great phone until the Lollipop update. Have called Verizon Tech service for assistance and have done a hard reset. Phone is under warranty, a replacement with a refurbished phone has been offered. I don't want a refurbished phone. Did hard reset again and seems that battery life has improved. But, I still have wifi connection issues. When will that be fixed? Who is responsible for the failed update? Is it Verizon, Samsung, or Android. It has gone long enough. Do something...Please!!!!!!
