Hi,
similar situation here: I have Mi Note Pro (Leo) and it's been a while since development ROMs have been released.
However China Stable Rom has been released recently.
Does anyone know why no more development ROMs for Mi Note/Pro (Leo) have been released?
The device still works very well, it's lightning fast and latest ROMs (released last year) were working like a charm. I see no reason for buying a new phone.
