Hi
I found a strange behaviour: When the camera is active (you see the image of the camera on the screen) then the LED which indicates that the battery gets charged by the USB cable, is turned off.
So if you have an application which uses the camera a longer time the battery will be discharged
Where to switch off this strange behaviour?
Thanks.
Do you use the 12 MP Camera Module? If so please see this topic
Hi @Deaffish ,
indeed on Fairphone 2 with the 12MP rear camera module charging the phone while the camera is in use won’t work. This is definitely an unfortunate problem for video calls, caused by a power conflict between the camera flash led and the PMIC.
For your use case you should be able to replace the 12MP rear camera with the 8MP rear camera (you can normally get that module for free or for cheap in the forum buy/sell section). With that module charging should work as expected while the …

No, I am using a 8 MP camera module. Seems that the problem is independent of the module, 8 or 12 MP.
I would report in the issue tracker as the statement that it effects o ly the 12MP module is from fairphone

It seems to me that it is more a (hardwired) hardware problem. With an second FP2 with LineageOS 18.1 there is exactly the same problem.
But with a third FP2 with LineageOS 18.1 (<= my phone) this issue does not exist as I have mentioned in the thread linked above:
Without knowledge but with experience: I have just connected my FP2 to my charger and opened the camera app. The charging LED stayed on with the camera app open and I could watch the battery percentage increase. This was on LineageOS (with the old camera module) but I doubt that this is different on the other OSes. So at least this is not a general problem.
Therefore this cannot be a general issue.
I have found, since updating to Android 10, that the camera sometimes switches on when I start charging the battery, and therefore the level of stored charge is compromised.
