You've heard the theories. Phone manufacturers slow down older devices to push people into upgrading to new ones. This theory has led to lawsuits, settlements and software patches, but what's the verdict? The answer is a bit more technical than you may think. We've got the clarification for you right here.

Dottie from Boston, Massachusetts loves to go on long walks with her partner. Unfortunately, that means she sometimes loses her phone while enjoying the scenery. She asked me for the best app for tracking down her lost Android.

I suggested Google Find My Device. By installing this app on a trusted person’s phone, you can use Google Maps to find your way back to your lost Android. You can even secure the device to make sure strangers aren’t sneaking through your secrets.

Even better, you can add a message for anyone who finds your phone, letting them know where to find you. In a worst-case scenario, you can even erase the device. (Hopefully, you’ll find it before you start considering that, though.)

Download the app here for Android.

I didn't forget about you, iPhone owners. Here's how to find your lost device.

Being able to see color is a significant evolutionary trait. We can see how blue the sky is or how beautiful fresh flowers are. But, it turns out not all of us see color the same way, and scientists now believe women can see more colors than men. So why is this?
