While using deep sleeping apps, the app stated as deep sleeping clears/swiped away on its own from recent apps tray. This behavior makes deep sleeping feature unreliable. I was placing an order from a shopping app (slated as deep sleeping), and on the payments page i went back to check my balance from another app, upon checking my balance i pressed recent menu button to go back and what what i saw that the shopping app was not there on recent app tray. I had to start all over again. This behavior to deep sleeping apps should be changed to manual closing by the user as with the case with normal normal apps (apps not set to deep sleeping). Deep sleeping feature is useful for battery saving but this automatic closure of apps makes this feature unreliable.
