Aren't you buying for your Dad? If so more important what your Dad prefers than you.
My Mum had a tougher time with Stock Android than MIUI, same with my sis but I prefer Stock over it. Depends upon the type of user.
Yes, need one for my dad. My dad is a clean slate and a quick learner and hence can learn whatever is taught. You mean MIUI interface is easier than Stock? My comment on settings page says otherwise.
Anyone facing Heating Issue with Mi4i ?
I am facing a lot.
Hope you have updated the OS. Check for updates from settings if you haven't. Mi4i had heating issues before the update. Now users report heating issue have gone down by a significant margin.
