What buttons bro? They don't have dedicated lcn fav, if you mean accessing fav means pressing left arrow, then scrolling the list and press ok button then it is painful process don't you think? Similarly even though you remember LCN it is not practical to press 3 digits to switch to next fav channel! Also due to many things going on in human mind, it is always easier to forget the lcn..so why take additional burden to remember random LCN when you have other useful thing to rememberIt has favourite option but just like Tata Play binge box favourite button is missing on remote, to access favorite channels they have introduced method by using other buttons on remote
Also remembering LCN number of ur favorite channels is not superhuman thing, human brain automatically registers the same in memory when u perform certain tasks for week or 10 days
