Hello friends, after many attempts I managed to configure the game to stop having this bug, and in fact it hasn’t happened again. The graphic configuration that I’m going to provide not only solves this, but also, at least in my case, achieved a reduction in battery consumption.
Within the game settings, under ‘Display’, select ‘HD mode’, ‘Classic image mode’, screen brightness 50%. Then, within ‘Graphics’, ‘FPS 30’, resolution ‘High’, sharpness ‘off’, visual effects ‘high’, shadows ‘high’, fog ‘high’, post-processing ‘disabled’, anti-aliasing ‘to each person’s preference, I use it disabled to save phone battery’, environment detail ‘high’, monster effects ‘high’, liquid dynamics ‘low’, water effects ‘low’, bloom effects ‘disabled’, enhanced reflections ‘disabled’, ray tracing ‘enabled’, reduce PvP effects ‘enabled’
Finally, within the Samsung Game Booster, I use the battery saving profile, I don’t use customization for Diablo Immortal, motion smoothness in games ‘60 Hz’
With this configuration, I stopped having visual problems in the game, and also I notice that even though the game settings aren’t at the lowest, the battery consumption is better than setting everything to ‘low’ which is the cause of the visual bug that makes the game dark. I hope you can do your tests and verify this to establish it as a definitive solution.
Regards!
