I think in other threads with the purple screen the consensus was a stuck IR filter which is a hardware defect. The split screen I can’t explain, but I imagine the camera will need to be replaced.
Yes they did say you could use a magnet On the side to try and move the IR lens back
My my daughter has a new V2 just started The purple problem 3-4 days ago , Tried switching night mode off and on Did a factory reset , tapped on it , And it’s still purple , She has not tried the magnet yet , She doesn’t have an SD card in it either
