My Galaxy S4 has been unusable since the NG6 update was installed. All apps are up to date, tried the factory reset 'fix' as directed by verizon support, problem is now worse. Phone crashes, freezes constantly, OS runs away and burns up the battery. SD card is mostly unreachable, phone randomly shuts off. Tried safe mode & that's unstable too. Plus the apps I use daily are not available. Unless an update is provided within the next few days I guess the only option is to get a 3rd party firmware & OS for the phone. I would also like to know how I am going to be compensated for the lost service since the upgrade as I am paying for service I do not get.
