@Gordon: I tried to power the display through the VBAT and 3V3 (right next to the GND pin).
I am using the connector on the display side. I tried to swap SCL and SDA too. I got 3 displays out of the box, I tried each display, same behaviour.
@DrAzzy: I have 10k pull-ups on both SDA and SCL. I although tried to put 4k7 resistors, without any better results. The display is rated between 3V3 and 5V. In my case, I could not damage it (or should I say , damage them, because I tried each of my 3 displays)
Weird, isn't it?
