Since KitKat, I can no longer connect to my home network, can only connect via wi-fi to networks of KitKats choosing apparently. Can no longer choose to save to my SD card which should be my choice not the operating systems. My phone now has to be charged daily and it only gets minimal use daily during the week. On weekends I have to now charge it even during the day and all night. System is much slower. Pictures are fuzzy and used to take perfect sharp pics. I have checked other Android forums and these are typical problems after KitKat. Verizon needs to provide another system update to revert the system back to JellyBean for those of us that has basically experienced a destroyed operating system.
