I sorta recently got a new LG Tribute 2 (Leon), which there are no ROMs for, and I just HATE Lollipop with all the memory leaks. After a few days of being on, apps will just randomly close like my music player when I'm on Firefox or the Facebook messenger bubble just closes as I'm typing or reading a message. Whereas on KitKat, I never restarted my phone outside of when my battery died. Right now Metro PCS has a great deal to get a free Samsung on5 (quite a bit better than my phone) and it comes with Marshmallow installed. So is Marshmallow as stable and memory leak free as KitKat?
