codynunes: I am guessing I been using Nokia Recovery Software approx 7 times. Firewall on router is disabled, only uses normal Windows 7 firmware.
I dont have any maps installed on phone. No maps cached on phone. Its empty. Almost nothing on phone installed. The camera seems to get corrupt when I go from 8.x to 8.1. I mean update 1+2 8.x did not corrupt camera. Its something with 8.1, I dunno what it is however. I am pretty sure, almost 100% sure if I downgrade using Nokia Recovery Software again, camera will works, but that does not solve my problem.

Wait if your phone is unbranded (unlocked?) is Cyan available for you without the Preview? Do you have Cyan already? Yeah, I believe you know what you are talking about, and I am kind of out of ideas also. I don't know why the camera driver is not being loaded, or why maps keeps crashing.

Maybe you tried this pattern already. Nokia Recovery- update all you can without preview app. Get preview app and update to 8.1, then update to gdr1. Reset and reboot as you feel necessary. Good Luck! I wish I could help more, and I am not sure if Microsoft Mobile will be of much help :/

I will try to download latest Nokia Care Suite and see if I can get some more information before I downgrade. Thanks for your help codynunes. Too bad I'm having this problem...

When i run the phone in TEST mode with Nokia Care Suite, "Camera interface test for second camera" + "Secondary camera Non volatile memory self test" fails.

Now I know that the camera driver can go corrupt somewhere during the upgrade process.
I have downloaded NaviFirm+ and flashed my phone to stock rom. Phone works great but I wonder what the problem is...

FWIW, camera and video working OK on AT&T 1020 post U1 install...

same here, unlocked ATT lumia 1020, atfter 8.1 update one (DP) my lens is stuck open and no camera apps working. installing apps doesnt work, clearly a driver got broken on update ( very very annoying as i only just got the phone and have already spent a day going all the way from 8.0 to 8.1 DP.

anyone find the solution? just a hard reset best? or recovery tool better?

[TheNerosam]

I reinstalled just the Nokia camera app and it started working again

[lumia0323]

Does anyone have a solution for this problem? I am back on WP 8.x and camera works fine. How do I get drivers to get propered installed? i tried over 10 times without any luck. I can't go WP 8.1 preview or GDR1 without camera stops working. It have worked but doing a update today fails. Anyone? Please, this is a bug right? It seems my investigation lead to a driver missing somewhere causing the camera to stop responding.

Try updating again. Maybe it will work this time.

Enever I am glad that I am not the only one having this issue! ... but I feel sorry for you. Its not fun at all....

Have you found a solution to the problem? I have tried everything... hard reset, recovery etc. upgrading to 8.1 results in camera fails (hidden driver issue somwhere)

Found this thread on other forum. More users having the same problem. No fix yet... No wonder why CYAN is delayed for 920/1020.

Problems with camera on Windows Phone 8.1 Developer Preview

[anon(8171782)]

I downloaded the dvp last night and i didn't have any single error installing all update.took about 5hrs.since I was on wp8. After update.only camera app ihave problem with was Nokia camera beta. The Nokia camera works fine.even the lock app works smooth on my phone.with no freeze.

[anon(8171782)]

I have 1020 btw

[lumia0323]

I did a new installation today... again same problem. I only think LUMIA CYAN can solve my camera issue. I will wait for Italian ROM to be released. I am soo mad at Nokia. No support at all. I have product code 059T911

[anon(8171782)]

Some people already saying they are getting cyan on Lumia 1020, if u are back on 8.0, check for update.

[codynunes]

Did you get Cyan?

[anon(8171782)]

Yes,got it last night.did you?

[yohannyphm]

use the original nokia camera, not the beta one.

[lumia0323]

I placed a ticket to Daniel at NOKIA SUPPORT SWEDEN regarding that camera does not work with CYAN. I am guessing its a Windows Phone 8.1 issue and not CYAN. Same problem with camera happens with WP 8.1 preview as WP 8.1 official with CYAN.

yohannyphm: Does your Lumia 920 work CYAN? I mean camera?

[Kryzzly]

I too am having the exact same issue. At first I thought it was a hardware fault in Developer Preview and Cyan. I used the recovery software to reset back to vanilla 8.0 and the camera worked again. It seems once it updates to the developer preview and then Cyan it stops working.

Kinda sucks :/ ....I recently got this phone in July and will need the camera for my job coming up in September. Nokia Care Live Chat doesn't open till Monday.

[yohannyphm]

Mine fixed itself after a while running the dev preview. No need to do hard or soft reset. Now I'm a happy camper. BTW when I updated to last dev preview my L920 lost all sounds not even on bluetooth no luck after several hard and soft reset I reverted back several times and re upgraded no luck. After last update and one soft reboot it got fixed.
