@Da_G:
This is a little put down kind of thing for users like me with retro devices having 64 MB RAM
If the base os code is done that means they are not going to work on memory leaks that GWES.exe, Shell32.exe, device.exe and filesys.exe are having. GWES is the top memory eater. In 21815, it increased a bit, people with phones having less ram should have notices it. Memory usage wise, 217xx series was better. Maybe we, old device users, should go back to 6.1 now. But the increased battery life always stops me. I get double the speed and responsiveness in 6.1 but in 6.5, battery life is more than 1.5 times.
