APPLE AUTOMATIC SOFTWARE UPGRADE

Good Evening, My review on Apple. They are a bunch of rouges!!!! Last Friday, my Apple 6 and Apple 8 were perfect. Then an automatic update . which you are forced to accept, failing your device could become dysfunctional, now my Apple 6 has died and Apple 8 takes fuzzy photos. A colleagues experienced exactly the same!! Are Apple forcing users to upgrade their phones, as they did with the battery saga several years ago. This is plain ******ion by Apple!!!!
