Google Pixel orders exceed 8 million

The Google Pixel 7 and 7 Pro phones launched by Google became extremely popular due to their latest technologies and camera  The Nikkei Asia website states that the number of orders received for the two phone models has exceeded 8 million.

Compared to last year's Pixel 6 series, the number of orders received is higher, and by 2023, the sales volume of Pixel 7 will also be very high compared to the previous data, according to Google. And due to the high amount of orders received, Google has informed its suppliers to produce more than 8 million units. For that reason, Google says that the company should double the shipments of Pixel smartphones compared to this year.

The Google Pixel 7 and 7 Pro phones are priced at $599 ($599) and $899 ($899), respectively. While it is lower than the starting price of the Apple iPhone 14, many critics are of the opinion that it has received a large number of orders due to the quality of its features. However, due to high demand and online orders, Google has made arrangements to carry out these orders without any country.

Currently, this model is expected to be released in 17 countries, and we can think that Google phones can become very popular in the phone market by 2023. Before this heat subsides, Google mentions that they will give their users the opportunity to get a professional experience through the upcoming Pixel Tablet. They further mention that they are more concerned about its Features and Specs and mostly it can be very less in price compared to Galaxy Tabs and iPads.

How to increase the battery life of your mobile phone

The mobile phone has become a communication device that is used by everyone big and small. But all of you use the mobile phone as you wish. Charge whenever you want, full charge, or even charge from the moment the phone turns off. If you go to charge in this way, the life of your phone will decrease. And it can have a big impact on the home electricity bill. So, stop making these mistakes while charging the phone.

Unplugging the charger from the socket

Many people leave the charger in the socket even when they are not using the phone. It can actually be dangerous. Because even when the phone is not connected, the charger continues to draw electricity. This can cause danger to you or someone else. Also, keep in mind that the higher the electricity bill and the longer it is, the higher its temperature, the more it will catch fire and ignite something nearby, or if the humidity in the room is high, it may even short out. That's why after you finish charging the phone, unplug it from the socket and remove it.

Charging the battery until 100%

Some people try to keep the phone 100% charged at all times. But that reduces the life of the phone battery. Generally, any battery has a certain number of rounds that can be charged, so if you charge it frequently to the maximum capacity, that number of rounds will quickly run out. Therefore, maintain the maximum phone charge between 70%, 80%, or 90%.

Charge the phone after the battery dead

There are some people who only charge the phone when the battery is at zero. It is bad for the phone. It greatly affects the life of the phone. Get used to charging when the battery is about 20%.

Charging the phone until dawn

Because it is easy to use in the morning, and because it is fully charged, I leave the phone on charge at night and go to sleep. It causes the phone to charge beyond the number of hours it should be charged. Sometimes the phone may be hot in the morning. It helps to shorten the life of the phone. So charge your phone before going to bed at night. If possible, turn it off and sleep.

Using it while charging

Never use the phone while it is charging. Thus, electricity is supplied to the battery and removed from it at the same time. Having to engage in two actions at the same time, it damages the battery and can create dangerous situations for you. If you want to make an urgent call, unplug the phone from the charger at that moment and charge it after the call is over.

Charge while having a back cover

Another thing that affects the life of the phone is the high temperature. Therefore, avoid charging with its back cover. Or the temperature produced there is trapped inside the back cover itself. It affects not only the battery but also the other devices inside the phone.

Using another charger

Every phone comes with its own charger. But instead, by using a charger of another brand or a charger of the same brand but made for a different model, there are cases where the battery supplies less or more electricity than the required amount. Then the phone may charge very slowly or overheat. Therefore, use a charger suitable for your phone.

Connecting to the laptop and charging

Many people connect the cable to the laptop and charge the phone while working. It takes time to charge the phone and it is bad for the phone and laptop. Because of that, over a period of time, the charging of the phone is stolen and the charger becomes inactive. Always charge the phone through a wall socket.

Stay Safe!!!

Automatic recording of incoming calls from unknown numbers

About a year ago, Google introduced the ability to record calls to the Google Phone app on Pixel devices. Shortly afterward, Google launched this feature on several Nokia and Xiaomi devices. It is reported that Google is currently working on the Google phone app to enable automatic recording of incoming calls from unknown numbers.

XDA-Developers' website has been able to uncover some new code strings that highlight this feature through a teardown in version 59, the latest update to the Google Phone app. As stated in the first string thus detected, the other person in the call with you will be notified of each recorded call. In order to use this call recording feature, you must first agree to allow calls to be recorded. It also states that all recordings recorded in this way will be stored only on your phone.

The other strings thus detected confirm two automatic call recording options, one called "Always record" and the other "Cancel". However, Google has not yet officially confirmed this feature. Keep in mind that this feature is only a feature detected through an app teardown.

You can use the XDA-Developers website and the GSMArena website to learn more about this feature.

Learn more about the best 13 privacy features of iOS ahead of Android

With the new Privacy Update on WhatsApp, many people are talking about this Privacy. This article is about the privacy changes that Apple has made to the iOS operating system. Apple has been passionate about privacy for many years. Apple believes that users who use their products, especially the iPhone, should have an understanding of how their data is used (Privacy and Data Transparency).

01. Sign in with Apple: You have seen options like Sign in with Google / Login with Facebook on many web sites and apps. But because it collects user email and other personal information, Apple provided this signing with the Apple facility. The special feature here is that you can use the Random Email Address provided by Apple instead of your Email Address. This will prevent annoying News Letters / Promotion / Ads from reaching your Email Address.

02. Location Usage Request: If an app accesses your geolocation, it allows the user to grant permission. The special feature here is the ability to enable the Location Service only when using the relevant service.

03. Clipboard Access Notification: You can see this notification every time you copy and paste something from another app and it will also give you a hint about if an app accesses your clipboard without notifying you. A number of popular apps, including Tiktok, embarrassed by this and were later removed.

04. Camera and Microphone Recent Usage: This will make the user aware of the apps that are using your camera and microphone. Upon accessing the Control Panel, the app shows the camera or microphone used.

05. Camera and Microphone Usage Indicator: When an app accesses your camera, a green mark is made and if the microphone is accessed, an orange sign is indicated near the signal bar. This allows you to block camera or microphone access without notifying you of an app.

06. Safari Privacy Report (Intelligent Tracking Prevention): This allows Safari Browser to track the activities that you visit on a particular website (Browser Activities) by other websites and how many Tracking Sites can be blocked. To do so, go to Safari Browser, tap on View Option [AA] in the Address Bar and go to Privacy Report. It allows you to see how many websites are tracking you.

07. Trust Your Device: You often use a charger to charge your iPhone, but sometimes you have to connect it to a computer and charge it. But when you connect your iPhone to a guest computer, even if the phone is unlocked, asking for your passcode again will prevent you from unknowingly transferring data.

08. Private Address in WIFI: Normally when you join a WIFI network your device will share a unique identification number called MAC Address to the network and it will always be one. This allows you to easily track your device, and this private address on iOS uses a different MAC address on different networks, blocking you from being tracked. (Settings -> WIFI -> Connected SSID (WIFI Name) -> Info -> Private Address)

09. Precise Location: If you do not want to give your location to an app, you can stop it by going to Settings> Privacy> Location Service App Name> Precise Location. This gives the app only the approximate location you have.10. Local Network If an app communicates with a device on your local network, that is, on the WIFI network, the permission for that is stated here. This will allow an app to control the hardware on the local network without your control.

Settings> Privacy> Location Service App Name> Precise Location

10. Selected Photos: This feature may make it difficult for you to use the app that works with Photos after you update to iOS 14. What happens here is that instead of giving full access to your image gallery, only the photos you have selected will be allowed to access the relevant app.

11. App Usage and Analytics: This allows developers to limit the sharing of errors and usage patterns (crash data and analytics) that may occur when using an app.

Settings -> Privacy -> Analytics & Improvement -> Share with App Developers

12. Quick Disable FaceID / TouchID: This is also a very small but important safety feature. If at some point someone tries to unlock your phone by forcibly pointing it at your finger or face, this can thwart that attempt. What happens here is that by pressing power + volume up you will be taken to the Shutdown screen and the passcode will be prompted when unlocking again.

13. Control Third Party Keyboard Access: Third-party keyboards sometimes have more features than stock keyboards. But if they get what you type, they have the opportunity to control it. (Often this data is used by developers to improve features such as Auto-Correction / Auto Suggestion) But if you do not wish to provide such data, this will allow you to limit it.

Settings -> General -> Keyboard -> Select Third Party Keyboard -> Disable Allow Full Access

Smart Wireless room 2022 with Xiaomi, charge everything via wireless even at a distance of several meters

Xiaomi. unveiled its latest wireless charging technology, Mi Air Charge Technology.

They point out that with this technology it is possible to charge several devices simultaneously, giving 5W of power to one device even at a distance of several meters.

What makes it special is that you do not have to touch the device on the wireless charger as is currently the case with wireless charging systems, and can charge even a mobile phone while playing a game or walking within the relevant range. Exists.

It also has the ability to charge speakers, lamps, and other smart home devices from things like smartwatches and fitness bands, allowing you to keep almost all the technical devices in-room wireless.

Developed by Xiaomi, the device has five-phase antennas that track the location of the devices needed to charge it, and with the help of the information obtained, another 144 antennas are used to direct millimeter-wide waves to the device.

For the mobile phone or charging device, two types of antennas have been created, a beacon antenna array that uses less power and a receiving antenna array, which is an array of 14 antennas, to exchange information about the location of the device.

The millimeter wave signals received through this receiving antenna array are converted back into electricity through the charging file contained here and the ability to charge the relevant device.

However, a representative of Xiaomi confirmed in a statement to The Verge that a commercial product featuring the technology will not be released this year.

How to focus objects in mobile phone camera - II

Now trying to go a little deeper. Before that, I have to say these are a little hard to really describe. Lots of misunderstandings. Because the crystal is not as beautiful as we can see. I will try to explain it as simply as possible. Those who invented these technologies really deserve respect. Before going forward, please read our part-1 'How to focus objects in mobile phone camera' article.

  

CDAF - Contrast-Detection Auto Focus

This process involves moving the camera lens around and selecting the right position until an object visible to the camera reaches the maximum intensity (Crisp / Clear) that the camera sensor receives. This means that the sensor determines that what we want to take the photo is clear and focuses there. This is a Trial & Error process. From the CCD section mentioned in the previous article, the camera processes all the data coming to the camera at that time using its algorithms.

Trial and Error. Trying to be right. In other words, when we do manual focusing on a DSLR camera, we shoot and trial a few photos and test them one by one to see which focus range is best. That's how he does that part for us from the inside of the camera. 'I do not take photos but I try some frames and find the right focus'. Again, this method uses the highest intensity.

Advantages of CDAF

• This method does not require any other hardware other than the camera. What is needed is a good algorithm. As the quality of the algorithm used by the camera maker increases, so does the quality of the photos. 
  

• This method usually gives a good clear picture. CDAF can provide a very clear photo if it is focused exactly

Disadvantages

• CDAF is a very slow mechanism. The reason for this is the use of the Trial & Error methodology. This mechanism takes about a second to focus on a photo. If the photograph you are trying to capture is a moving object, there is a good chance that what you want will not be there when you focus. 
  

• This mechanism cannot function in semi-darkness or without light. Light is a mandatory factor because the focus of an object depends on the intensity relative to it. But if you have a flash on your cell phone, you can get some level of support from it. But it is not as successful as natural light.

• The CDAF mechanism cannot hold the focus on moving objects. This is because, as I said before, the Trial & Error methodology does not allow it to continue to focus on something that is moving. Therefore, it is very difficult to make a good video recording with a camera that uses CDAF.

PDAF - Phase-Detection Auto Focus

This is a bit of a complicated but fast process. This works by using a phase-detection photodiode attached to the camera sensor. This photodiode converts the light received by the camera into an electrical signal (Light into an electric current). In this PDAF mechanism, a sample of 10% or less of the pixel data of the image received by the camera sensor is taken to the photodiode mentioned earlier. The resulting pixel sample data is collected in a scattered manner on the sensor.

The photodiode then separates the data from the right and left of the camera lens. This process is similar to the process by which our brain creates a single image from two images received by our right eye and left eye. Then this data and light locations are processed by an algorithm related to the photodiode and the position of the focus in the relevant region (Phase) is confirmed to be correct. If that focus is not right, the previous data will be used to adjust the camera lens to the correct position. Then the camera will get the correct focus. A trial & error story is therefore not needed here. The process is thought to be very long but it takes only a fraction of a second for it to work.

Advantages of PDAF

• This method is very fast. It takes about 0.3 seconds. It can be activated three times faster than a CDAF. 
  

• A moving object can be easily photographed through this. Also, when recording a video, you can continue to focus on the object (Continues Focus).
  

Disadvantages

• Like CDAF, PDAFs are difficult to operate in semi-dark or light. Even in this method, light is a mandatory factor and the process is not correct. If you have a flasher you can get help. 
  

• This is a slightly more expensive mechanism. A few years ago, a camera with PDAF was only available on high-end flagship phones. But now that size has been put aside and dropped a bit. However, PDAF is not yet seen in most budget ranges of mobile phones.

Dual Pixel Auto Focus (Dual Pixel PDAF)

An improvement on the PDAF mechanism itself, is the dual pixel PDAF mechanism itself. In this case, we use two instead of the photodiode we talked about earlier. Also, instead of the> 10% pixel sample used in PDAF, almost all the pixels received by the sensor are given to the two photodiodes. This allows the camera to capture faster, more accurate photos or frames. Here, using two photodiodes, each pixel data is used in two ways. One is to get the data in the photo as well as set the correct focus position. Therefore, the efficiency of taking a photograph increases with productivity.

The pros and cons are no different than PDAF. But because the resources used are more and more expensive, mobile phones with dual pixel PDAF are not cheap either. The story about Focus is not over yet. Today's article is longer than the previous article. Tried to explain quite a bit. If there is something you do not understand, please don't hesitate to comment.

Cheers! 

How to focus objects in mobile phone camera - I

If you have a DSLR camera, you can adjust the focus by rotating the lens. Even in the auto mode functionality, the adjustment can be seen by the naked eye. Today we are going to find out how the mobile phone camera mechanism takes place to adjust the lens to capture objects. Basically, several technologies can be used to find the focus of a mobile phone camera. Each cell phone uses a different technology. You can see that some mobile phones use two or more technologies.

We can categorize these options into different technologies. Let's see what are the focus types within these three categories separately.

• Passive Auto Focus
• CDAF - Contrast-Detection Auto Focus
• PDAF - Phase-Detection Auto Focus
• Dual Pixel Auto Focus (aka Dual Pixel PDAF)

•  Active Auto Focus - Laser Auto Focus 
  

•  Hybrid Auto Focus - Focus types using two or more of the above mechanisms (Eg: PDAF+Laser AF) 

Let's see, what are Passive Focus and Active Focus.

Passive focus is the process by which a stream of light from an outside object passes through the camera lens and is set to focus on the distance and light intensity of an object by an algorithm provided by the CCD (Charged Coupled Device) on the camera sensor. A part of the camera sensor detects the location and distance of an object and adjusts the lens. For a passive focus to function properly, it must have both the light and the object contrast (Lighting condition and Contrast) relative to other objects. Then it is certain that a Passive Auto Focus does not happen in the dark. So how exactly do you focus in the dark? That's when the Active Focus Mechanism emerges.

Before we talk about Active Focus, we need to talk about Sonar Beam. Ever wondered how the shapes of seabed objects (like sunken ships) know the distance? What happens is that ships or submarines send a sonar beam, which is a very sensitive range of sound, to the seabed. The distance to the object is determined by calculating how long it took for the beam to collide with the object and reflect back. This process has been developed to the extent that the shape of the relevant objects can be identified. Sonar radar systems operate on this principle. This is very easy to understand if you understand how an ultrasonic sensor commonly used in Arduino works.

Off the topic: Dolphins, considered to be the most intelligent species in the world, use this sonar beam to communicate with their species many miles away. Even today, scientists do not know how to do that. Turning to the Activate Focus again, it simply means that the technology works in the same way as the Sonar Beam or Ultrasonic mentioned above. The difference is that it uses a laser beam. The device emits a laser beam and adjusts the focal length by calculating the time it will take to hit the object and recover. That means an Activate Focus works even in a dark place. Having light is not a mandatory factor. Then you will understand by now why Active = Active and Passive = Passive as I said earlier. 

The rest is just one category. Hybrid, or Hybrid Focus Mechanism. This is very simple to say. Using two or more Activate and Passive Focus Mechanisms to adjust the Focus Length is called a Hybrid Focus Mechanism. Easy to say but a very complex process takes place here. We will talk about that in the next section. 

Usually, when we say hybrid, the first thing that comes to mind is a car that runs on both liquid fuel and electricity. But the word hybrid literally means hybrid. This means that any process that combines two types of technologies in any science can be called a hybrid, any process that enhances efficiency and productivity. Hybrid Autofocus Mechanism is one of the hybrid processes that is working in zoology, botany, automotive technology, and camera parts.

In this hybrid category, two Passive focus mechanisms (Mechanism) or two Passive Active mechanisms can be used to find the exact focus.

• Passive + Passive = PDAF + CDAF 
• Passive + Activate = PDAF + Laser AF
  

There are two ways to create a Hybrid Focus. You can usually find a Hybrid Focus Mechanism in the High-End mobile phone with the flagship category or close to it.

Samsung expects to launch networks with 6G technology by 2028

You may know that Huawei had begun testing 6G technology. Samsung, a well-known South Korean technology giant, hopes to launch the next generation of communication technologies, 6G technology, sooner than expected. Samsung says it will launch in 2028 and expand globally by 2030. A report released by Samsung entitled "The Next Hyper-Connected Experience for All" details the expansion of the 6G network.

 

However, Samsung has said it will focus on the 6G network in a context where even the 5G network has not yet expanded globally, as it usually takes at least 10 years for a network to research and develop and expand, with no plans to delay its launch. That there is no reason. Sunghyun Choi, head of Samsung's Advanced Communications Research Center, said the decision to start work on the 6G network was based on that fact. It took tech companies 15 years to switch from 2G networks to 3G and the world has been able to upgrade to 5G within 8 years.

With Samsung's latest revelation, the world will shift from 5G technology to 6G within this decade, with 6G expected to deliver speeds of around 1,000GB per second. It is said that with 6G, the air latency will be less than 100 milliseconds and the 6G network will be 50 times faster than the 5G network. It is also expected that AI technologies will grow with the 6G network, and it is expected that high-speed 6G will be available by 2030.

How to unlock your phone while wearing a face mask

Apple released the iOS 15 update for iPhone users last year. As usual, Apple has been releasing small updates for a few months. Apple has released the first beta release of iOS 15.4 for beta users, and XDA - Developers website reports that it includes some special features requested by Apple users. One of the most exciting new features that came with it was the Universal Control feature, which lets you install iOS / iPadOS 15.4 on an iPad and update your Mac to the latest macOS 12 beta release, allowing the mouse and keyboard on one device to control another device.

Also, one of the highlights of this update is the new feature called "Face ID with a Mask" which allows you to unlock your iPhone even if you are wearing a face mask. So far when you try to unlock your iPhone wearing a face mask, you know from experience that the system does not recognize your face correctly, but as a solution, if you are wearing an Apple Watch, Apple has given you the ability to unlock phones. You may remember that. So this new feature introduced by iOS 15.4 will be more effective than that option, which will allow you to easily unlock your iPhone even when you are wearing a face mask.

According to reports from the Mac rumors website, the iOS 15.4 update will also feature several new emojis, including emojis such as "melting face", "saluting face", "peeking eye" and "dotted line face". Will be reported. If you update your Apple phone to a new iOS version, please comment on us by using these new emojis. 

There is no official word yet on when iOS 15.4 will be available to everyone, but according to a recent beta release, it's possible that every iOS user will receive the iOS 15.4 updates in a few weeks. You can use the XDA-Developers website, 9to5mac website, and Mac rumors website to learn more about this.

Cheers!
