Isn't single take feature available for s7 edge??

earlier the battery backup was good but after oreo update the battery drains very quickly.samsung plz provide another update and resolve the issue asap.

this is the second time i have fallen in samsung trap thinking that the familier problems of hanging slow device and auto restarting wont happen in a flagship phone of samsung.But i was wrong and now i pity myself why i have fallen for samsung again....
