@Karthik48 It very much depends on your use case.
If you don’t play games and rarely watch Full-HD videos on your phone you will never notice the SoC.
The SoC outperforms (in raw power) a Qualcomm SD615, what may be found in the XIaomi Mi4i for ~200€ and in European phones for ~300€ or more.
There is no SD Card Slot. The build quality is great, the shape feels good in the hand.
I do prefer the home button of the M2 Note, yet the M1’s blinking light is cool.
swiping up on it brings you back one step, (short) pressing to the home screen and it is the notification led.
The camera is decent, in low lights not the best but this is to be expected from most devices.
