Blue light filter for Galaxy S7 Edge?

There isn’t such an option on the International version of the Galaxy S7 Edge.

I’m not too sure about other variants.

There are quite a few Blue light filtering apps out there. You can pick one and hope Samsung includes it in the future update.

3 months of using my S7 n I was surprised with the built in B.L.Filter in my husband Note 7.
You have to download a 3rd party app.
Blue Light Filter – Night Mode by Simple Design Ltd. is the best substitute I’ve found.

Lies s7 edge has Blue light filter since nougat 7.0.

The above answers are given way before the Nougat update. They were right back then.

After Nougat update, you no longer need a 3rd party Blue light filter. It comes built-in. Just open the Quick Setting panel from the top of the screen and tap the Blue light filter button to turn it on and off.
