On my main profile night mode was on , on my work profile it was off.
Today this started to happen. Bottom of my screen started to flicker black and white.
I was I WhatsApp at main screen at the time , and then complete WhatsApp starter to flicker and pixelate. I have rebooted the phone , and tonight my unlock screen where I type password started to flicker between night and day mode , black white all time flickering. I have manage to unlock it somehow and entered WhatsApp again and it all startet to shift back and forth between black and white theme , including my keyboard and WhatsApp and all on screen.
