Hi! I want to buy a smartphone for my mother. The one she's using right now is Mi Note 4 (for more than 2 years now). She doesn't have any issues with it as such, but recently she has realized the importance of 'camera', because of Zoom meetings and video calls. Mi has screwed up the operating system over time, so I would really avoid buying an Mi phone. Usage is quite limited to games such as Angry Birds and YouTube.
