Unable to adjust brightness



Hello,

My phone's brightness is set to a locked value and neither the slider in the notification bar, nor Brightness level option in Settings seems to have any effect. First thing I tried is downloading an application called Night screen which is able to change the screen's brightness - it asked me for "Allow write system" permission and it worked. However, I did not see this as a permanent solution, so here's a few other things I tried:
  • Changing Adaptive brightness option

  • Factory reset

  • Phone Repair in PC Companion

  • Flashing another official firmware through FlashTool


Additional info:
Model number: D6603
Firmware: 23.5.A.0.575

Any help is greatly appreciated.
