Some of my photos get pixel errors. But the errors aren't visible immediately. When you later watch your pictures again, the errors appear at once. But not on every picture.
Every picture is safed on google photos, but the original on the device is destroyed. I don't know why.

I’ve managed to upgrade to the version 153.
After that I performed the tests again with the same 256GB NMcard and the issue with corrupted files seems to be resolved.
At least I could not reproduce it yet.
So, I suggest to update the firmware of the phone as soon as possible.
