Samsung has to provide this basic feature to all M Series phone.
Limiting the basic network capabilities of device even though it has a
powerful processor, is not a good idea. Neither Samsung nor customers
get benefit out of this decision. So Samsung...
I am agreeing with Ritu321 and Nick95 here... Samsung should have
explicitly stated that M series devices doesn't support LTE-A or CA... I
am not seeing it mentioned in the specifications of any M series
