Hardware quality is 3 years old budget phone.
My main compliant is screen. Adaptive brightness is not working, either too bright or too dark. Screen colour tempureture is too blue.
Another thing is the case. The hole of Charging port is too small so often USB cable isn’t fit enough to charge the device.
Software works okay, but I feel UX is now not up to date while other OSes have been improved a lot in recent years.
But generally speaking UX is quite smooth.
I reckon it’s quite efficient if I take the hardware specs.
Overall the C2 has some shortcomings to use as daily driver.
