Coming to the other system changes on the new build, OnePlus has now optimised the startup speed of some apps for a faster launch. There are some bug fixes that rectify delay of receiving messages, a volume adjustment bug and a bug that affected the speaker output. The fifth Open Beta build also brings the December 2020 Android security patch to both the devices.
OnePlus has also fixed the call freezing bug that was triggered when someone got an incoming call while listening to music via a pair of Bluetooth earphones/headphones. Apart from this, some new camera animations have been added to the phone, and can be seen when switching over to the front camera.
