bro you won't get thjs feature at least for M51....that is for sure...if you want please buy A series phones from samsung or otherwise you may opt for other brand phone....where CA will be basic feature... as for as samsung concern CA is a premium feature.....
It is the power of our feedbacks only, that samsung gave clipboard. Now, lets flood samsung will feedbacks about carrier aggregation on all channels, to get it in future updates. Becoz our processor supports ca and we need it.
