Huawai P30 Pro: main cam not focussing – ToF problem?
9 months ago
Hello, on my Huawai P30 Pro (2019, full Android, full Play Store access) the main camera doesn't focus any more in regular mode. It's fixed to a macro distance. I wonder if it has to do with a defect ToF camera (read symptoms below). Do you have any helpful ideas?
The defect occurred just like that, after snapping a pic. There has been no shock, no unusual software manipulation, no humidity. All lenses on the phone's back side seem unchanged. I have the phone in my pocket a lot while walking, since late 2019. There was a recent software update, but the camera didn't fail immediately after the software update. A restart didn't help.
Now when I tap the screen, the exposure may change, but the focus remains fixed – anything further away than 10 centimeters or so is blurred.
One interesting thing: I take many photos of books pages (for later text excerpts) - perhaps more than any other subject. And the focus is now frozen just so that a book's page is still correctly focused, but anything super-close or further away is blurred.
- The problem also occurs using the camera app's HDR mode (which I need sometimes).
- It also occurs in the camera app's "Pro" mode with both automatic and manual focussing (MF doesn't work any more), and with or without "AF assist light". I didn't see anything helpful in the camera settings.
- The problem ALSO occurs using other camera apps (tried Cymera and Camera Zoom FX; both seem to access only the P30 Pro's main camera, and they show the same problem as the Huawai camera app with the main camera, also when I select "Infinity" mode).
Under some conditions, photography with my broken phone is still possible:
- wide angle cam fully works
- tele cam fully works
- main cam in "Super Macro Mode" fully works, also for distant subjects, focussing any distance correctly
So I CAN use the main camera in "Super Macro Mode". But "Super Macro Mode" has these disadvantages:
- requires extra taps each time
- doesn't allow exposure correction as in "Pro Mode"
- doesn't combine with "HDR"
- doesn't use camera's "digital bokeh" (?) – it creates much more sharpness throughout (even though there is a slight focus change between Nearby and Infinity). I usually like the "digital bokeh", even if it slightly smoothes the main object itself. The "Super Macro Mode" feels a tad harsh sometimes.
So do you have any idea if that is repairable and if a local phone repairer would be up to the job?
Thanks!
