I have as primary phone samsung S7 edge but I need a secondary dual sim phone.
I got a Meizu 3m note this summer, is not much bigger that my s7 but it feels like too wide for my hand, battery life is very good. I also got it white because I needed fast from retail store and I usually don't like white phones, meizu looks better than others but I always thought that black would be better.
I would like to change that phone with a xiaomi but I'm not sure if it would be better a mi4c or a mi5
Size: mi5 seems more like an s7 flat, that is smaller than the edge and the curve on the back make it feel smaller. Mi4c should be a little smaller but it doesn't have the curved back.
Screen: from video on YouTube is not possible to understand if and how the 2 screen compare. I guess mi5 screen is better.
Battery: I didn't find much info about the comparison between the 2 device. I read some posts where some people complained about MIUI8 battery drain on mi5
SIM size: I'm not sure if mi5 use nano sim
On my if I need to use your global rom I don't need to unlock the bootloader is that correct?
