Why is Carrier Aggregation support turned off for M31...?
What's wrong with you Samsung....? How much premium amount do you want the customers to pay you for basic features like Carrier Aggregation?
Your devices under Monster series really **bleep** at network reception. People are pissed off with M series.
Why is it you are not providing CA inspite of so many customers asking for the feature?
If you can't provide customer request and work on feedback just stop advertising yourself saying you provide best connectivity and features.
