I bought a Nokia 3.1 as a lower end test device, which also belongs to the Android One program. The device is so slow to respond to input in every way that it's become the device I use to test our apps absolute worst case performance on.
Even knowing it was meant to be a lower end device it routinely gets frustrating to use for even the most simple tasks, such as Chrome tab switching, keyboard response and even just plain navigation.
We have had similar, buy not as bad, reactions to other low end device we use for testing.
I genuinely feel sorry for people who use these devices as their primary phones.
