Depending on what you use your FP3+ camera for, you might want to give this camera app a try on it:
Of course I’m biased, but I’m really happy I installed GCam on my own FP3+ (running /e/OS, too):
P.S.: GCam can’t be found in an app store, you can find links in the above topic. I for my part installed Nikita: NGCam_8.2.300-v1.8.
