It's annoying for taking photos, but besides that it's a really good way to make the phone a less enticing timewaster. I have done it on previous devices, but used my new phone as an opportunity to switch back to grey. We'll see how long it lasts this time, though.
As it turns out i am a toddler just fascinated by shapes and colours and everything is more boring in black and white if you struggle with being on your phone a lot and doom scrolling, Iโve found that setting my phone up to go grayscale/black and white at certain times really helped me!
on apple itโs on shortcuts and on android I think itโs modes&routines (?) Give it a try! I hope this helps someone ๐ซถ๐ป
