Camera App and Flashlight Not Working

I'd dropped my Huawei P9 a few months ago and the screen broke pretty badly. I finally ordered a LED+Digitizer from iFixit and got my screen replaced just last week. But now, when I try to open my camera app, the black rectangle animation of the app opening just barely reaches the edges of my screen before the app crashes/force closes. I've tried seeing if the camera will work on other apps, but it will force close Instagram and just gives me a black screen on Messenger.

I went back to the guy who helped me replace my screen. He opened my phone up again to check the camera pins and he said the camera pins were fine. He even connected my phone to the old screen again to see if there might've been an issue there(?) but the camera app and flashlight were still not working. He insists that it's a software issue and that I need to factory reset my phone, which I'm all but ready to do, but I wanted to reach out into the community and see if anybody had other ideas about what the issue might be.

It's a Huawei P9 EVA-L09. My camera and flashlight were working absolutely fine before the screen replacement. (Everything was still working smoothly except for the screen, really.)

Thanks in advance for any help!

I have a P9 Plus and I have exactly the same problem. Even the trouble shooting part is exactly the same as my experience. Does any one know how to get t a diagnostic tool to test the hardware on Huawei Phones. Please help.

Hey, you could indeed try to reset it. But I don't think that will help. While replacing the lcd did you disconnect the camera?

I have the same problem on an P9 EVA-L09 with software version EVA-L09C432B398, The back camera works but as soon as you switch to the front camera, nothing works anymore and the app crashes. You have to force stop and reboot in order to get back camera functionality again, otherwise the app always crashes ?? This happened after a battery replacement (I have tested with a new front camera, it didn't help).

I'd be grateful for any sort of help!!

EDIT: Flash still works for me, but i first had to activate it from the lock screen. (it was blacked out in the quick toggles in the notification bar)

Let the battery discharge completely until the phone turns off. Charge the phone for five minutes. Then turn it on and test the camera. That worked for me. You do not need Hard reset or anything complicated

“Restart the Huawei P9 (hold the “Power” button and the “Home” button at the same time for 7 seconds until the phone turns off and vibrates).

Go to Settings, open the Application manager and then go to the Camera app. Select on Force stop, clear data and clear cache. Restart your phone again”.

That worked for me. Good luck.
