The smartphone is great! Beautiful screen, powerful at work. The main advantage is the Android One program. Updates come on time and without delay. Pure Android is fast and stable - no complaints. The battery is small but holds up well - 1-2 days of moderate crystallization is enough. Overall, I'm happy with the smartphone. You can point to a slow proximity sensor that works slowly, but not critically. I am waiting for an update to Android 10 (scheduled for January 2020). I think by then this smartphone will be relevant and interesting and 1-2 more years with Android 10.
