So, Is Battery Life Gonna Be A Problem For The Foldable Razr?

  So, Is Battery Life Gonna Be A Problem For The Foldable Razr? Motorola’s new foldable Razr phone is pretty neat. Not only is it a pretty impressive feat of engineering, it packs a nice dose of nostalgia for those of us old enough to remember the days when the original Razr flip phone reigned supreme. There’s just one thing that, at least on paper, raises a red flag. That 2,510 mAh battery. Well, technically it’s two batteries—one in each half—that add up to 2,510 mAh. To put things into perspective, that’s tiny compared to every other smartphone released in 2019. Samsung’s Galaxy S10 has a 3,000 mAh battery, while all the new iPhones top 3,000 mAh, with the 11 Pro Max boasting a 3,969 mAh battery.

Plenty of iconic Aussie snacks didn't deserve to die but Australia has had a slightly sordid history when it comes to keeping our snacks free of racist and homophobic undertones. Here are five Aussie snacks that you won't find in 2020 because they were rightly discontinued.

According to an investigation by Checkmarx security researchers, some Android devices may have an unpatched security flaw that an app could use to record you without your knowledge using your device’s camera and mic.

No attacks that exploit the bug have been reported so far, thankfully. Still, the Checkmarx researchers were able to successfully create and execute commands that could remotely record phone calls; capture photos, video, and audio; access GPS metadata from photos; and even check whether the phone was facing down—meaning hackers may one day create their own clever attacks for devices running an unpatched version of a device’s default camera apps.

Qantas chief executive Allan Joyce, alongside captain Helen Trenerry, speaks to reporters in Sydney after a direct Qantas flight from London to Sydney successfully touched down just under 19-and-a-half hours. The trial flight, part of Qantas's Project Sunrise, carried just 50 people, including crew. Mr Joyce says the company has been evaluating two aircrafts - the A350 and 777-8X - over the last few years as potential carriers for the route. "Now we're convinced that both aircraft can do the critical missions," he says. (AAP Video/Michael Wade)

To bring things up to code with a new FCC standard, Android recently added an "Emergency broadcasts" feature that will make your smartphone notify you whenever a potential safety threat or Amber Alert is posted in your area.

Google and Samsung released patches for impacted smartphones earlier this year, but Checkmarx’s report suggests that many other Android smartphones may still be affected. Fortunately, there are ways you can check if your device has been patched.

Check for the bug on Pixel phones

Pixel users can check for the patch easily: simply open your device’s settings then go to Apps & Notifications> See All Apps> Camera> Advanced> App details to open the app’s Google Play Store page. If the app has been updated since July 2019, you’re in the clear.

Check for the bug on other Android devices (manually)

If you’re not sure whether your smartphone’s manufacturer has issued an update for your phone’s camera app that fixes this bug, one way to find out is to try exploiting the bug yourself (which comes care of Ars Technica).

The new Motorola Razr is the most desirable smartphone in years, but there are 4 key reasons why you shouldn't buy it

  The new Motorola Razr is the most desirable smartphone in years, but there are 4 key reasons why you shouldn't buy it The new MotorolaRazr is the most desirable smartphoneI've seen in years, and yet it's not a phone that people who care about functionality and value should buy. It has a high price tag, less-powerful specs, fewer features, and foldable-smartphone technology still has a long way to go before it's as reliable as regular smartphones. Instead, the new Razr will appeal to those who value fashion and design. After all, it looks like the iconic Razr from the mid 2000s that's been modernised into an ultra-sleek smartphone with a long, foldable screen. Visit Business Insider's homepage for more stories.

Google updated its Google Camera app Wednesday to add support for Android Wear. To launch the app on your smartwatch, simply open the Google Camera app on your phone . Your Android Wear device will then display a card for remote capture.

If you suspected your phone were being tracked and wanted to start covering your tracks without snapping it in half, your first bet might be to simply Stingrays are also known as cell-site simulators, or IMSI catchers. They mimic cell phone towers and send out signals that can trick your cell phone into

You’ll need:

  • A PC (this will work on Windows, Mac, and Linux).

  • Your Android device.

  • A USB cable to connect them.

Once you have those materials, here’s what you need to do:

  1. First, you’ll need to install and configure ADB tools on your PC. All the necessary files and instructions for installing ADB for your PC’s OS can be found on the XDA Developer Forums.

  2. After ADB is installed and configured, plug your Android phone into your PC with the USB cable. Next, we’re going to try to use codes to force the phone to take videos and photos without accessing the phone’s camera app.

  3. Open your PC’s command terminal. On Windows: Press “Windows Key+R,” then type “cmd” and hit “run.” On Mac: Press “Command+Space” to open the Finder, then type “Terminal” and double click the Terminal icon to run.

  4. In the command prompt window, run the following commands one at a time:


Open your phone’s camera app and go to your photo/video library to check if the commands worked. If you find a new photo or video, then the bug is present on your device.

If you haven’t updated your device’s camera app in a while, try checking for updates via the Google Play Store. Once you’ve installed anything that’s available for your phone’s default camera app, try the above ADB commands again. If they still work, you should report the issue to your device’s manufacturer as soon as possible. In addition, stay away from unknown camera, video, or audio recording apps, since this is the most likely method for hackers to slip malicious code onto your device and take a few photos.
