Verizon's OnePlus 8 5G Phone Will Need Its Own Unique Third-Party Cases
Verizon's version of the OnePlus 8 is physically different on the outside compared to versions of the smartphone available from other carriers. The external differences are significant enough that Verizon's device won't fit in cases made for any other version of the smartphone, because this particular version places the volume buttons in a slightly different location.
Compared to all other versions of the OnePlus 8, Verizon's OnePlus 8 5G UW pushes the phone's volume buttons down slightly. Non-Verizon versions of the device feature volume buttons that are located slightly above the power button and almost directly across from the alert slider. As for why Verizon's version has relocated volume buttons, it has to do with the additional 5G mmWave radio.
What the change means for buyers of the OnePlus 8 5G UW is that you need to be careful choosing a case. Certainly, the OnePlus 8 cases sold at Verizon will fit its version of the device. Anyone who buys a case outside of Verizon's offerings will need to ensure they are getting a case that is specifically designed for the Verizon version of the phone or it won't fit. Interestingly, among the cases that reportedly won't fit are the official OnePlus offerings.
Verizon doesn't offer the OnePlus 8 Pro, that device isn't fully validated for the Verizon network at this time.
