Samsung Should provide an update or an option to roll back as the 180 mb update on 22nd Dec is a disaster.. my battery started draining faster than usual and in standby initially I lost 2-3 % whereas now I loose 5-6%

Can Samsung do some software editing where we get the option to use the scanner as a home button rather than pressing the button physically

I have a j7prime device and when the battery goes below 50% phone automatically goes into power saving mode ... how to stop this
