This is the first time I hear about this. You could try and go into settings -> Apps & Notifications -> see all xxx apps -> three dot menu in top right corner -> show system -> scroll down to splendid -> storage & cache -> clear storage.
If that doesn't help, then go to settings -> system -> reset options -> reset app preferences (this is lika a soft factory reset. All apps and data will remain but most app settings will be reset).
If this doesn't help, then a full factory reset will be the next step. Or that you find a custom setting that you like. Could be a hardware issue but lets try with the software first
