Blue light filter is just one of the many essential features embedded into the new Samsung Galaxy flagship smartphone. Activating this display feature is highly recommended if you are sharing your phone with your kids. It’s one way to reduce, if not, totally inhibit harmful light emission (radiation) from the phone. 

While smartphone manufacturers are required to abide by the FCC guidelines in regard to radio frequency radiation absorption by the body, some smartphones including iPhones and selected Galaxy models may still have exceeded the radio frequency radiation safety limits. This is an alarming notion because radio frequency radiation from these devices may have adverse effects on human health, especially with 5G rolling out globally. 

Thankfully, new Samsung devices including the latest galaxy s20 lineups already have built-in display features users can use to safeguard themselves from such harmful radio frequency radiation. Thus, be sure to make full use of this display feature on your new smartphone.

And that covers everything in this tutorial. Please keep posted for more comprehensive tutorials, tips and tricks that will help you make the most of your new Samsung galaxy s20 smartphone.
