I am in transition between a OnePlus2 and a Moto G4 play.
The OnePlus2 has a removable back plate and OnePlus offers their own case which then encases sides and rear and protudes up enough to offer good all round protection. It is a basically $400 device so I kept in a case from new as cases wear I replace and on I think the 3rd case in >1 year of use.
The G4 play is a $130 device so I use it naked just with a screen protector as dropping a $130 phone is less $ consequence than dropping a $400 device.
It is a minor issue but given microUSB2 is more ubiquitous than USB-C I’m looking forward to go back to 1 cable type.
