If the camera on a Galaxy S23 is blurry, shaky, slow or says Camera failed, wipe the lenses and clear the Camera app's cache before you suspect hardware. The S23 has a 50 MP main camera, a 12 MP ultrawide and a 10 MP 3x telephoto. After One UI 8 some owners reported the image trembling while changing zoom and heat when the camera opened; clearing the cache and installing the next patch were the fixes they reported.

Test in Safe mode
ReversibleIf the camera works in Safe mode, a downloaded app is conflicting; remove the newest ones.
Use the other lens to find the culprit
ReversibleSwitch between 0.6x, 1x and 3x. If one lens is poor and the others are fine, clean that lens and, if it still fails, book service for it.
Model-specific
What is true of this model and not of its siblings
- The S23 camera set
- A 50 MP main camera, a 12 MP ultrawide and a 10 MP telephoto with 3x optical zoom on the back, and a 12 MP front camera. Each is a separate module, so a fault on one lens does not mean the others are failing.
- What owners reported after One UI 8
- The picture trembling as zoom changed and warmth when the camera opened. Clearing the Camera cache and waiting for the next patch were the reported fixes.
Stop boundary
When this stops being a self-service repair
- !If Phone diagnostics fails the camera test, book service
- !If the lens glass is cracked, have it replaced
- !If autofocus hunts in good light only, ask Samsung to inspect the module
