How Credit Card Skimmers Work, and How to Spot Them

How to Enable Wi-Fi Calling on an Android Phone

If you’re on a carrier that supports it, Wi-Fi calling is a great feature to have. It will allow your smartphone to use the best connection in your house to make and receive calls and text messages.

How to Back Up Your Mac and Restore Files With Time Machine

Regular backups are essential.

How to Make Your Samsung Galaxy Phone Feel More Like Stock Android

The Galaxy S and Galaxy Note are some of the best Android phones available right now. But TouchWiz has a bad rep for being ugly and “bulky” (especially with Android elitists).

It’s actually pretty easy to get a near-stock experience on most Samsung phones—you’ll just need to download and tweak a few things.

What Can You Do With Samsung’s Bixby?

It seems like every technology company under the sun is working on a voice-controlled assistant to go up against the likes of Google’s Assistant, Amazon’s Alexa, and Apple’s Siri.
