Assalam-o-Alaikum Furqane, I heared that you're facing some issue with Adaptive Brightness. Kindly note that Adaptive Brightness means that your phone Brightness will control automatically. For Example,at bright light ,it will automatically Increase the brightness and at dark it will set the brightness level to zero. If you know that and still facing the problem then kindly clean your phone with a clean cotton cloth and then check again. Note: Sometimes the dust appears on Sensor and due to the dust,sensor not worked properly. And if still facing the problem then bring your phone at your nearby Samsung Customer Care Centre. I hope that this method helped you. Take Care.
