Doogee S60
After several times of trying to take photos under the immediate water-surface, water leaked at the top right corner so a black blob appeared on the screen in that corner. After 5 years of using it, it died off: presumably, water droplets got from the charging nest (i forgot to cover it when taking photos near a sprinkle) and it seems that the battery died as well. As for the rest, great phone it was.
