After some experimenting, my recommendation for video is clearly Blackmagic. No other app gives you that level of professional control. And Blackmagic cures the abysmal sound quality of the FP6, which is due to a ludicrously high levelled pre-amp, which results in overloading the analog to digital converter. The heavily clipped output of which even gets worse with post-processsing. On some apps, not only Blackmagic (Open Camera as well and also the OC fork of Fairphone/e/OS) you can switch the input stream to “unprocessed/raw”, but the main culprit is the utmost extreme setting of the pre-amp. In Blackmagic, simply tap on the VU meter to get a gain control slider, turn the amplification down until audio peaks only seldomly hit at -5 dB (you can also turn the VU meter into a peak meter to ease that levelling) and you get clear audio…
For camera, I would like to hear recommendations. Normally, on the net, and in reviews, Pro Shot wins most competitions. Pro Shot has an Evaluator package that will tell you what Pro Shot detects in your hardware, and it does not see the full resolution (50 Mpix) of the Lytia 700C sensor, and not the 32 MPix of the Selfie camera as well.
I had very good (!) e-mail exchange with the developer of Pro Shot. And he tells me that it is not by chance that his app does not see 50 MPix: Since Android 11, device manufacturers (here: Fairphone) may declare one camera app to be stock (“whitelisting”), and so that installs in specially protected storage, and only from there will it see the entire hardware.
So basically this is something intentionally done by Fairphone to block out other camera apps. They can only see 13.1 MPix on the main camera and 7.1 on the selfie cam and are thus unable to compete with the not-so-professional standard apps that Fairphone (or /e/) ship.
So this is basically an instrument by Google to block out competition and I wonder why Fairphone takes such a measure which is basically unfair to it’s own customers?
