The OnePlus 5 has barely hit the market but it’s already receiving its first software update. It’s a pretty typical early set of patches, but it should be a welcome update to anyone who managed to snag the phone early.
According to OnePlus, the update brings the phone to OxygenOS version 4.5.2 with no major Android upgrade. It fixes a few issues with the system itself and app installations failing, plus optimizes a few things.
App installation issue
System update failure
Compatibility with 3rd party apps
If you have a OnePlus 5, make sure to check for OTA updates to get started.
