Need help

I was looking at old threads on this forum and it seems my whole page layout has changed to this grey colourless scheme which was the same as the old threads I was looking at. I hate it! How do I change it back to normal? I am using an android phone. Have tried restarting my phone and browser

Here I have attached photos

Please mods help
