How to Give Alexa Multiple Commands Without Saying Alexa Every Time (Video)

Amazon finally allows you to have a more human-like conversation with Alexa. What I mean by that, is they’ve allowed you to give multiple commands in a row without having to say, “Alexa” Every. Single. Time. So for this tip and trick Tuesday, I wanted to show you this new feature and why it saves so much time. The feature is called Follow-Up Mode and you can enable it in the Alexa app for each specific Echo device. This video was sponsored by Blinkist. They make an awesome app for Android and iOS that converts the most popular non-fiction books […]

Huawei P20 Pro on Table

Huawei P20 Pro Complete Walkthrough (Video)

The P20 and P20 Pro, two quite unique phones from Huawei, were just announced and Huawei was kind enough to give me a little time with each before they were launched. So as is the usual here on my channel, I used that time to try and do a complete walkthrough. Now, if you aren’t familiar, a complete walkthrough on here is me trying to go through as many features as I can on a device so you guys can be better informed on what the device can do before you decide if you want to buy it in the

Intelligent Scan vs Face ID

Intelligent Scan (Galaxy S9) vs Face ID (iPhone X) (Video)

Now that the iPhone X started to make face unlock a bit more mainstream other manufacturers are all getting on board with, not adding facial unlocking, which most have had for some time, but with marketing the feature upfront now and coming up with better ways of implementing it. Samsung recently launched their Galaxy S9 and S9+ and with it “Intelligent Scan” which isn’t so much a new tech as it is a combination of their existing Iris Scan (which scans your eyes for authentication) and then defaults to their facial recognition if that isn’t available–all within milliseconds. But, as

How to Use the iOS 11 Document Scanner Feature

One of the more useful features in iOS 11 that not a lot of people talk about is the new built-in document scanner feature in Notes. Where you normally would have used a third-party app to do this type of scan (and there are good ones that I like out there), this one is super easy to use and is built in to iOS so, you know, it’s just better. To scan any document (super handy for business cards in my opinion), simply open the Notes app. Tap the new note icon at the bottom right. Tap the plus sign above

Android P Notification

How to Update to Android P Right Now (Video)

There’s a new version of Android out called Android P (my money is on it being named Peppermint when it’s released to the public, for the record) and Google has released the developer previews. If you aren’t familiar, the developer previews are really meant for developers to test out their apps on the latest version of Android in order to make sure it works, maybe integrate new features, etc. but it’s also what people like us (see: nerds) like to install in order to test out and play around with new features before they are released. Now, it goes without

Camera Comparison: S9 Plus vs Pixel 2XL vs iPhone X vs S8 Plus (Video)

Time for yet another Galaxy S9 experiment of sorts. In this video, let’s see how the Galaxy S9 Plus’ camera stacks up against the reigning champs of the iPhone X, Pixel 2 XL, and Note8. For this, I wandered all over NYC and managed to get the same shots on all four devices so we could line them all up and see how well they each did. Without further ado, here’s the camera comparison. Here are the photos for your own comparison below. Let me know in the comments which you preferred and why and follow me on social for

Typing to Siri Featured

How to Type to Siri Instead of Talking

Sometimes you don’t want to say the thing you need to Siri out loud. “Hey Siri, remind me to take my antibiotics for that weird rash tomorrow morning.” Maybe not that, but you get the idea. Interestingly enough, Apple actually added a feature that allows you to type to her instead and I’ve found it’s actually quick useful (not just for discrete Siri commands, but in situations where you’re in a quiet location, for example). Here’s how to enable typing to Siri instead of talking. Enable Typing to Siri Head to Settings. Tap on General. Tap on Accessibility. Tap on

Speed Test: Galaxy S9 Plus vs iPhone X vs Pixel 2 XL vs Mate 10 Pro vs OnePlus 5T vs Note8

Ok, let’s do an experiment with the new Samsung Galaxy S9 Plus. I wanted to see how it (and the Snapdragon 845 in it) compared to the other flagships currently out. Namely the iPhone X, Pixel 2 XL, Mate 10 Pro, OnePlus 5T, and the Note8. So to test it, I opened the same apps on all the devices running the same accounts on the same gigabit speed WiFi network and lined up the footage to see how long it took each to render and display the app or game. Now, of course, this isn’t the most scientific test, but

Stock Android on S9

How to Make Your Samsung Galaxy S9 Look Like Stock Android

The S9 and S9 Plus were released recently and they are a fine bit of kit. They feel more solid than the S8 and S8 Plus for some reason, the low-light camera is insane, and that screen? Drool. But what if you love the hardware but aren’t the biggest fan of the software or Samsung’s Experience UI (formerly TouchWiz UI). Now, I admit Samsung’s UI is way better than it used to be, but some people out there might want to use stock Android instead–no judgement, I get it. So in this tip and trick Tuesday, here’s how to make

Samsung Experience Landscape Home Screen

How to Rotate Your Home Screen on your Samsung Galaxy S9 Plus

So this might seem sort of basic, especially if you are used to using custom third-party launchers on your device, but Samsung finally is letting users rotate their homescreen to landscape mode within the Samsung Experience UI. Right now, this is only working on the Galaxy S9 Plus so who knows if they’ll let it come to other devices or not but feel free to check for the setting to rotate the home screen on your Samsung device and let everyone know in the comments if it works for you and what device. Otherwise, if you have a new Samsung

Samsung’s 2018 QLED TVs Complete Walkthrough

During an event in NYC, Samsung launched their new lineup of QLED, top-of-the-line TVs and I have to admit, they look damn sexy, have up to 8K upscaling on certain models, my favorite new feature ambient mode (which we’ll get to) and more. I got to spend a little time with them at the American Stock Exchange while a blizzard was raging outside, so I figured I’d try and do one of my complete walkthroughs. Now, if you aren’t familiar, a complete walkthrough is where I try and go through as many features of the device as I can and

Two tips and tricks in one week?! Crazy, I know. But with the launch of the new Samsung Galaxy S9 and S9 Plus (and the fact that Samsung was kind enough let me use one before its release) there’s just a few videos I want to get out for anyone who might be thinking about getting an S9 or just got one and are curious about some of the newer features. So, for this one, let’s check out how to use super slow-mo, the feature that records 960fps to give you some epic short clips. Firstly, the 960fps super slow-mo,

How to Set an Image as the Always-On Display on Your Samsung Phone

With the launch of the new Galaxy S9 and S9 Plus, I figured I’d do a few quick tutorials on the site for anyone who picked one up and wanted to learn some tips and tricks for it. For this tip and trick, let me show you how you can set an image as your Always-On Display screen (instead of our usual boring clock). This tip and trick was actually taught to me by MrMobile, Michael Fisher and works on any Samsung Galaxy device with Always-On Display and Samsung Experience UI. This means, the Galaxy S7, S8, S9, Note8, etc.

AR Emoji

For this week’s tips and tricks Tuesday, I figured it was fitting to go through a feature on the newly launched Samsung Galaxy S9 and S9 Plus. So in this episode, I’d like to show you one of the more controversial features that the S9 phones bring: AR Emoji. If you aren’t familiar, AR Emoji are essentially Samsung’s version of the iPhone X’s Animoji except that they can also resemble you instead of a 3D version of an emoji. In addition to that, they have an agreement with Disney for Disney characters to appear in the app, as well (and

Best New Features in 2018 Flagships

The Best Features Coming in 2018 Flagship Phones (Video)

The first batch of 2018 flagships are arriving and already there is a definite pattern. A lot of the new devices that are being released are all utilizing the Qualcomm Snapdragon 845, which I spoke about when it was announced back in Dec and was honestly really excited about. And even though it’s only been a short bit since the chipset was announced, all the usual players are already releasing flagships with it and the new features it enables. This means that there is now a pretty solid expectation of features that flagships in 2018 will have that I think
