I give up on this bug. The S5 Plus had official lineage 15.1 and 16.0 with this bug in it. There are 652 commits that separate the 14.1 and 15.1 kernel branches, in which this bug appeared. I will never have the time to go through each and every one of those commits.Battery drain is not solved. 33% drop during 18 hours shut off. Clean install of 0426.
