Just to let you know still the same ,no difference made, look at Samsung notes compared to the move launcher which has been running longer in the background than Samsung notes and see how much battery has drained . I already did a painful factory reset which resolved in nothing
Contacted Samsung team they seemed to be less bothered to care and direct me to the community,
Can't put the app to sleep or deep sleep , can't even uninstall it , since the 3.0 update
