Yeah even with cached services your running at twice as much ram free as me. That's a massive difference and would explain my reloading. Maybe art & lollipop are just too heavy in this build... it would explain why they stopped rolling it out generally.Not sure if this is what you are looking for, I"m a bit of a noob in settings. I hit the show cached processes tab.
I just booted upto recovery and flashed my cache there and no going to manually close other cached serviced and see if it improves.
