The phone is not yet available, but it will be soon and i’m thinking of it to replace my 5 years old OnePlus X running /e/. It would be great to continue to use it on my new phone.
Since the device comes with Android 8.1 or higher, the device is probably treble supported so you will be able to install an unofficial GSI image.
Oneplus Nord would be a very nice choice containing e. Please consider selling the device as new with pre-installed e in your web shop, as you do with Fairphone3, instead of some old refurbished models. I will order one straight away.
