I am having many issues with My Samsung Galaxy Note 2 (Rogers), since the most recent upgrade. The battery drains excessively. It takes longer to recharge. The voice command features on the camera no longer work. The predictive text and automatic auto-correct is horrible and there are no options given to regain control over it. I want to return to the software that was installed when I bought the phone. As a consumer purchasing this phone with hard earned money I feel I am entitled! Please advise.
