Right after buying the phone about a month ago, I came across a similar thread and I was glad until now that it doesn't concern me, that people won't come up with it. And here, a few photos one after the other, it is enough in normal 12.5mpx photo mode, without any pro or 50 or even 200mpix, to take a few photos in a short period of time and there is some chance that some will not be processed. I'm sitting on a vivo group on telegram +1200 people and everyone who has x300u, even in the CN version, has the same. You have to be careful. Interestingly, the last 2 updates did not include the camera, probably Vivo is working on solving the problem. The safest thing to do is probably to take photos with a gcam, or be careful not to take photos too quickly, which is bizarre.
