LG to add Knock Code security to the LG G2 and the G Flex

LG Knock Code

LG has announced it will be sending out a software update containing the new Knock Code feature for two of its most popular smartphones. Owners of the LG G2 and the G Flex Android phones should be on the look out for the new software, which the company says is coming soon.

Knock Code was one of LG’s big new software features announced during Mobile World Congress, where it made its debut on both the G Pro 2 and the new G2 Mini. Proving it’s not only suitable for high-end, expensive hardware, Knock Code is also installed on the L Series 3 range, and the updated F Series devices.

We named Knock Code one of our favorite new technologies we saw at MWC this year, and in case you missed it, here’s what it’s all about. At the moment, phones are mainly unlocked using a PIN code, but Knock Code takes away the number aspect, and replaces them with a Morse code-style system of taps. These taps don’t require the screen to be on either. LG has found a way to keep the touch layer active, so no button presses are needed.

The one-step unlock method has more than 80,000 possible combinations, and will accept codes between two and eight steps long, in your choice of area on the screen. It’s convenient, secure, and surprisingly, fun to use.

LG hasn’t provided an exact date for the update’s release, but says it’ll start sending the software out in April, but adds that specific details will be locally announced over the coming weeks. LG hasn’t been all that quick to respond to Google’s release of Android 4.4 KitKat, so don’t be surprised if the Knock Code update takes its time to reach your phone.

I record interviews for work. These are my favorite free recorder apps

Before you head to the app store on your phone to buy a voice-recording app, take a moment to consider the apps that may already be installed on your phone. Why? In my experience, they're likely all you really need. I’ve recorded interviews and voice-overs for work for years, and I’ve found the two best examples come preinstalled on your phone already, so they’re entirely free to use.

The best Samsung Galaxy Z Fold 5 cases: 10 best ones so far

Two Galaxy Z Fold 5 phones next to each other -- one is open and one is closed.

Samsung’s next-generation foldable is here with the Samsung Galaxy Z Fold 5. This iteration has some notable improvements, including a new hinge design that eliminates the gap from previous generations when the device was folded. You also get a 6.2-inch HD+ Dynamic AMOLED 2X display on the outside while having a 6.7-inch QXGA+ Dynamic AMOLED 2X display on the inside, with both screens having a 120Hz refresh rate. In other words, they're about as nice as you could ask for.

The Galaxy Z Fold 5 is made with premium materials, and the triple-lens camera system packs in a 50MP main shooter, 10MP telephoto with 3x optical zoom, and a 12MP ultrawide lens. There’s a 10MP selfie camera on the front cover, and a 4MP camera on the inner display. You also get a Snapdragon 8 Gen 2 for Galaxy chip inside for the best performance and power efficiency.

Google Pixel Tablet just got its first big discount and it’s worth a look

Tablets are a dime-a-dozen these days, with offerings from all the great brands including Apple, Samsung, Lenovo, and more. So, if you really want to stand out in a sea of similar tech, you need to do things a little differently. That's what Google's Pixel Tablet offers. How? It comes with a unique speaker dock that can be used to both charge the device and offer room-filling sound -- almost like a smart speaker add-on. Better yet, when your Pixel Tablet is docked it benefits from the Hub Mode, turning the device into a smart display, with digital photo frame support, smart home controls, and hands-free Google functionality. Of course, it could set you back at full price, normally $499 unless you find it included in a roundup of the best Google Pixel deals. Well, guess what? Thanks to a Best Buy Google Pixel Tablet deal, you can get it today for $439 and save $60. Hurry, though, it's part of Best Buy's recent 48-hour sale so it won't stick around for long.

Why you should buy the Google Pixel Tablet
Okay, okay, so in our Google Pixel Tablet review, Joe Maring did give it less than stellar remarks, but he called out its reliable fingerprint sensor, comfortability during use and excellent speaker dock. Honestly, how many tablets come with a matching speaker dock that transforms the entire experience? This tablet also marks a "lot of firsts" for Google, as it's the first tablet from the company in nearly five years, the first Android tablet in eight years, and can be converted into a smart home display with the speaker dock. All of which are notable milestones.
