Sony WF-1000XM4: Specifciations

Sony WF-1000XM4 come with support for Hi-Res audio over LDAC codec, which is much superior compared to the typical Bluetooth audio. They also come with support for the company's own 360 Reality Audio. The DSEE Extreme feature of the buds can help them rebuild compressed audio to something that is close to Hi-Res in quality using AI.

The buds come with the company's custom V1 chip integrated, which is said to maintain active cancellation of high-end frequencies and cut noise levels up to 40 percent better than the XM3's. The buds are also designed in a way to cut wind noise with the help of a new automatic wind detection feature.

Sony WF-1000XM4 come with 24-bit amps, with 20 percent larger magnets. The setup provides better cancellation signals at lower frequencies and can produce better bass according to the company. They also come with proprietary polyurethane foam tips pre-installed, which aid in passive noise cancellation.

Sony’s “Speak-to-Chat” feature, fast pairing support for Windows/Android, and an IPX4 water resistance rating are some of the additional features that help the Bluetooth earbuds stand out.

Coming to voice calls, the earbuds include a bone-conducting sensor and beam-forming mics to help provide the best sound quality. They also include support for Amazon's Alexa and Google Assistant.

Sony claims that the XM4's can provide a battery life of up to 8 hours with noise cancellation and the case can recharge them up twice. The case supports Qi wireless charging support, and the company claims that a quick 5 minutes charge is enough for 1-hour of playtime.

WhatsApp is yet again working on a new feature for the iOS version of the app. According to a report by WABetaInfo, the upcoming update will let the app show the profile picture of the contact in the notification itself. The feature is already available on the Android version of the app. This will help users to better understand who is texting them without needing to open the application.

The Facebook-owned giant is currently working on the new feature and there is no official word as to when it will be made available for the users. This will be one of the first feature updates in 2022 and it will use APIs in iOS 15 to show the WhatsApp profile images in notifications on both top-screen banners as well as the Notification Center.

As of now, the feature seems to be available only to a limited number of testers and it should be available to the masses in the coming weeks. If you are excited about the feature, you should keep an eye on updates for WhatsApp on the Apple App Store.

How to understand your car diagnosis codes and then what to do

Modern cars are quite intricate and one needs to take time to learn how to diagnose some of the car problems they encounter daily. However, other problems may be quite complex for the driver to diagnose on their own without professional help. Sometimes you could be driving fast and all of a sudden, your car indicator will turn on and demand that you “Check Engine”. When this kind of problem occurs, how should you go about it? How do you start to find out the source of the problem? Well, this is where the OBD2 code reader comes in handy to help you.

In this article, we shall examine what steps you need to take while using the OBD2 code reader. This will help you know some of the things you can do when you use the code reader.

First, find the menu

When you are done selecting your car model and other required information for the code reader, you will have to wait for the reader to boot up and then find the Menu. For you to diagnose your car engine problems, select the “codes” or the “Trouble Codes” on the main code Menu of the OBD2 reader. Here, your reader could present you with system choices such as Transmission, Powertrain/Engine, Brakes, Airbags, and so on. Pick any of these choices and you will see more codes. These are Active Codes or Pending Codes. Live codes refer to the malfunctions that are keeping the Check Engine lights on.

The Pending Codes refer to a failed OBD2 monitoring system operation and therefore in case it fails another time, then the Check Engine light will turn on.

What do the letters mean?

The diagnostic codes start with a letter. Here are some of them:

The letter P

This letter stands for the Powertrain and has the largest number of codes. The codes in this range refer to problems associated with the engine. Here, you can get codes associated with transmission problems, emissions, ignition problems, and fuel systems, among others.

The Letter B

This letter in the codes refers to problems associated with airbags, power seating, seat belts, and more.

The Letter C

This refers to the issues related to the Chassis. Here, you will find codes that cover brake fluids, axle, ABS, and others.

The Letter U

This covers issues in your vehicle that have to do with Undefined problems or issues with the vehicle.

Common Diagnostic Codes

Code P0420- this code refers to a problem with the catalytic converter. This can be diagnosed and repaired by experienced professionals.

Code -P04976: this coder refers to Evap flow during a non-purge condition. This system helps the car contain dangerous fumes and therefore when such a code pops up on the code reader, a technician will help repair such a problem.

Code P0171: This code refers to problems related to oxygen sensor issues. A problem to do with the oil and fuel ratio is the issue here. It means the ratio of the fuel and air leaving the engine cylinders is not as is required. As such, when such an error pops on the OBD2 reader, a suitable technician will sort it out.

These issues and reports are steadily rising, with the report numbers on Down Detector increasing from 243 to over 800 within a matter of minutes.

WhatsApp has not issued a statement regarding the issue. However, seeing its past record with such problems we expect the company to already be hard at work trying to fix it. But, considering the COVID-19 situation and that most people are working from home, we might see a longer wait than usual before the services are completely back up online.

The company usually issues a statement regarding what was wrong, after the problem has been fixed. But, if it takes longer than usual we can expect the company to make a statement about this on Twitter.

If we were to take a guess, the issues could have been caused due to a particular server not responding or down due to hardware issues.

The services are not down for all users and some are still able to do everything, this is because they might not be connected to the faulty server. If your services start to work and then stop in between multiple times, it means that the company is trying to fix the issue.

Back in October, Microsoft launched its first pair of truly wireless earphones, Surface Earbuds back in October. It is priced at $249 (approximately Rs. 19,000), which is a bit expensive for a pair of truly wireless earphones. To justify the price, the company has announced that the Surface Earbuds will now be able to control PowerPoint presentations too.

The feature is now currently only available to Microsoft Insiders running PowerPoint using Windows Version 2004 (Build 12730.20270) or later. The company is yet to announce the public availability details of the feature.

This new feature will become one of the USP's of the Surface Earbuds. No other truly wireless earphones available in the market claims to control PowerPoint presentations. The company says that this feature will come handy "for parents with work presentations and kids with end-of-the-year school projects."

How to control PowerPoint presentations using Surface Earbuds

  • Pair your Surface Earbuds with your PC using the Surface Audio app.
  • After the earbuds are connected, open the PowerPoint presentation that you want to present and start the slideshow.
  • Inside of the Slide Show mode, right click on your mouse and hover on 'Surface Earbuds Settings'. Now click the 'Use Gestures to Control Presentation' option. (Once selected, the setting will be remembered by the PC until changed)
  • You can now swipe forward and backwards on your left earbud to control the presentation. You can also double tap to play or pause videos embedded inside of the presentation.

Key points to remember while using the feature

  • PowerPoint presentations can only be controlled via the left earbud.
  • The earbud does not need to be inside of your ear to function as a PowerPoint remote, you can simply hold it in your hand and use it to control the presentation.
  • If you do not see the 'Surface Earbuds Settings' in the PowerPoint slideshow, confirm if the earbuds have been paired to the PC using the Surface Audio app or not. If not, reconnect them.
  • While controlling PowerPoint presentations using the Surface Earbuds, users will not be able to hear system audio. To let the system stream audio back to the earbuds, users will have to disable the feature by going into a PowerPoint presentation, starting a slideshow, using the right click, hovering on the 'Surface Earbuds Settings' and then tapping on the 'Use Gestures to Control Presentation'.

In terms of the specifications, the dual-SIM handset features a 6.67-inch fullHD+ IPS LCD display. The smartphone is powered by the Qualcomm Snapdragon 720G processor paired with up to 6GB RAM and 128GB of onboard storage. All of this is backed by a 5,020mAh battery with support for 18W fast charging.
