In my case Camera MX solved these problems too, but only temporarily. Not a single streak in my pictures since the beginning of March. Perfect, but …
… some days ago - I updated it from 3.4.202 to 3.5.001. And the streaks returned. Downgraded Camera MX, tried other camera apps, played with all their settings. No success. The streaks persisted. I changed my camera app back to Open Camera.
Thought I’d have to live with it until the next Fairphone Android update.
My FP2 is rooted. I mainly did it to mute the camera shutter sound. But it opened a world of new possibilities to play with. Via F-Droid I downloaded the app “Kernel Adiutor”. A wonderfull app with loads of complex options. Since the FP2 is a fast machine, my initial goal was to lower the energy consumption to make the processor run cooler and the battery last longer. I changed some parameters in the CPU and Temp section and monitored what would happen.
By accident I started Open Camera - and the streaks where - gone!
To make it short.
It seemed, the streaks and lines appear if you operate the phone at a minimum CPU freq. lower than 1267 MHz. At a minimum of 1267MHz or higher they disappear.
Since this was not satisfying, initially I wanted to save energy , I changed the value back to 300 MHz and played with the governors - “performance” did the trick for me.
At least there is hope for a software fix.
This seems hopeful, even though it means the camera wont provide good results in say battery saver (unless you alter the mode). A change of the handling of the camera app and maybe RAW-support and I will be very happy =).
Would be nice to have this confirmed with some of the mods/devs/other user, since this might not be easy to find out even if you’re looking for it.
A thought though, shouldn’t this issue be visible also for different phone makes? Or might it be that the OS (I’m guessing this has more with android to do than the fairphone specific additions? ) code in combination with this specific hardware is a bad combination?
I’m on 1.2.8 .Even though it did not say anything about the camera in the update information it seems to be working much better. I’ve tried to replicate the old behaviour but so far no ugly streaks (yes!). I’ve tested good and bad light scenarios as well as ‘battery saver’ and normal. Both camera MX and stock camera works just fine.
I suggest trying the new FPOSOS. It will get released shortly and be easily rootable from what I have read. Then you can try to solve the problem by adjusting the CPU frequencies and the governor.
My own FP2 runs perfectly using this method since the beginning of April.
Yesterday I installed the new googlefree FPOSOS.
Basically I’m really happy with the new software on my FP2 but unfortunately my camera showed the same behavior as in 1.1.7 and produced these coloured lines and streaks.
I rooted it in a second with a click in the developer options and applied the fix as outlined above. Now it continues to take clean pictures again
After a couple of weeks I have also noted that the lines appear again, but much less frequent than before the update. Both during battery saver and during normal mode. Would be interesting if the devs or someone else could confirm s99hs observations with the low CPU freq.
My FP2 camera has the same problem described. [quote=“Martin_Rhodes, post:1, topic:11840, full:true”]
Hi, just wondering if anyone else was having problems with the video function on FP2? When try to make a video there are long streaks and flicker across the image.
I have the same problem and another one: The focus makes every 10-15 seconds a little jump so that is not really possible to make a usable video. I changed the camera module but there is no change. Also the streaks and flicker are still there.
I have the same problem while recording videos; the camera tries to focus continuously although the camera already found focus. It will find focus faster if i touch the screen, but a couple of seconds later it will start again. As fairjuan states, the recorded videos are pretty much useless.
