Sounds horrible 🙁 I'm an S3 owner... I love everything about Samsung, they are my favourite brand alongside BMW.
Why must they murder the phone's day to day tasks with slower performance than the phone is capable of , the main use of the phone is day-to-day tasks, and the gaming and performance are the extra, but now the day to day tasks get to be slower than the S3, for better app performance ? Sigh
