The update brings a new feature called Clear Image for the camera, According to OnePlus, "Once you switch on the new Clear Image mode in the Camera app, nothing but awesomeness will be captured." Using algorithms, pictures are clearer, noise in low-light conditions is removed, and OnePlus says it adds detail to pictures that other cameras can't add.
Addressing the yellow tinting of the screen, the update adds a new, cooler calibration of the screen. Using the proximity sensor, the phone is now set so it won't switch displays while in your pocket. The touch keys are now illuminated better, and the overall stability of the handset is improved. Among the items fixed is one that prevented vibrations from being deactivated during "quiet hours." Another fix takes care of the bug that led the phone to refuse to update song info on the lock screen.
Also fixed is the volume of the microphone in "voice recorder," the failure of "Ok Google" to start Google Search and the failure of the "O" gesture to start the camera. Repaired is an issue that would put up the wrong sized wallpaper on the screen.
The update might take some time to reach you, so don't panic if it doesn't come right away. Hopefully, this update will solve the issues that have had a number of the phone's owners unhappy with the manufacturer's response to these problems.
Thanks for the tip!
