Zoom In and Out in the Camera App auf OnePlus
Pinch-to-zoom works in the OnePlus camera app, but it often causes shaky framing because both fingers move on the screen at once. A steadier alternative uses the zoom control built into the viewfinder.
Open the Camera app and tap on Zoom. A zoom slider or dial appears on the screen depending on the shooting mode.
Swipe left or right on this control to zoom in or out. This single-finger motion keeps the phone steadier than a two-finger pinch, which matters most in low light or with longer focal lengths.
Once the subject is framed the way you want, tap on the shutter release to take the picture. The zoom level stays applied until you change it again or switch modes.
Use pinch-to-zoom for quick, rough adjustments when speed matters more than stability. Use the swipe control when precision matters, such as distant subjects or video recording where camera shake is more visible.
