Explain what you are doing when this happens. Do you have Auto-Lock set for a period of time? Do you have Auto-Brightness set? If you have Auto-Brightness checked and you change the ambient, or surrounding lighting, the screen brightness will change. Depending on the time, Night-Mode will also change screen brightness.
My screen keeps going dim, it’s been happening since I bought the phone and now I have had enough, is this a hardware or software problem, it does it every now and then and takes several hours to go back to normal

Hi
Go to settings down to display & brightness also check auto lock.
Go to i books download ios 11 user guide & iPhone guide for your model iPhone.
Both are free.

It can be due to multiple things.
1) Make sure “Reduce White Point” is off
2) Turn up the brightness in Control Center
3) Make sure Night Shift is off
4) Make sure Auto Brightness is off
