Lollipop is terrible. Downgrade issues topic

Hi, I dislike Lollipop that much that I have taken the time to register and ask for assistance, I think it is the most terrible upgrade ever. I hate the white screens that burn my eyes due to having vision issues. Is there anyway around this? I tried to downgrade to kitkat but my baseband would go unknown and no matter what modem I would flash it would never reconnect back to my network lollipop works fine as far as signal and data concerned. I used the firmware supplied via sammobile. I really do wish to complain about how bad it is to be so used to the dark themed UI and to just be slapped in the face by google without any option to change this. Not to mention it is constantly buggy even after factory resets and I am on the 5.1 version. If someone can help it would be greatly appreciated.
