Huawai P30 Pro: main cam not focussing – ToF problem?

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!

Probably a bad camera - common problem on your model.  Call Huawai support line to get a local repair center location.

Another trouble with that phone is that the USB-C plug seems a little wide. Charger cable and headphone plug disconnect all the time, it's terrible when you move just very slightly.

I had that problem from the beginning (and it's the phone's problem, not a cable problem, checked that).

I wonder if a Huawei service could improve that too?

(Aware that i could use wireless charging and headphones, but i prefer with cable and on other phones there is no problem with wired connections.)

Hi, i just called a local Huawei Service which was well reachable by phone (after lengthy voice menu, but no wait loop). Here is the repair prices they told me (acc. to agent "supposedly" including VAT):

  • Back camera not focussing, "repair might cost 183 Euro"
  • Change battery, "fixed price 49 Euro"
  • Change glass, "might cost 173 Euro" (i gasped, he whispered "yes")
  • USB-C-socket too wide, "can't tell now"

For prices in USD, multiply with 1,05.

He said: "They will check the whole phone anyway and quote a repair price you can approve or not. The initial check is 25 Euro."

(The glass is slightly broken on my phone. It's stilly waterproof, as I inadvertently found out. The battery is not the freshest.)

What troubles me now – how to select the next model, with a view to good camera.
