Only if the stars were actually recorded by the sensor. Editing can increase brightness and contrast, but it cannot recover detail that was never captured.

The key limit is signal-to-noise ratio: stars must be bright enough on the sensor to stand out from the camera’s random image noise. If the phone didn’t gather enough light, those faint star signals are buried in noise, and post-processing can’t reliably tell real stars from random bright pixels.

So, if the stars are already faintly present in the file, careful editing may make them more visible. But if they were not captured above the noise floor, there is no practical way to “enhance” the photo to show where the stars were.
