I had a slight issue with the OnePlus 5, though - it didn't recognize the SIM card.

I rebooted <- nothing
Took the SIM card off, put it on again and rebooted <- nothing
| The mobile is Dual-SIM, so: |
Took the SIM card off from the outermost slot and changed it to the innermost slot <- recognized <- rebooted and now everything ok.

(the SIM card is Lycamobile Portugal and I'm currently residing in Finland, though I suspect that doesn't affect anything, but still FYI)
