Greetings - My FP4 was working great until I replaced a cracked screen. After that, only the primary camera worked; the selfie camera was a white blur.
I removed the FP cover to check that nothing was covering the camera module. All seemed fine. Didn’t change anything. Replaced FP cover.
After closing the FP again, the selfie camera works again… however now the MAIN camera shows only a white blur.
Software is the latest available upgrade. No third-party camera software ever installed. Rebooted several times over the past few days. Still only have a working selfie camera, but the main camera shows just a white blurry screen.
